Preface I Outline of this PhD thesis and the PhD project This thesis is based on the ADDITION-study, the Anglo-Danish-Ducth study of intensive treatment in people with screen-detected diabetes in primary care. The ADDITION-study was developed and implemented in cooperation between the Department of General Practice and the Steno Diabetes Centre. The ADDITION-study investigates the effects of screening and intensive treatment including poly-pharmacological treatment and behavioural change, on patients with Type 2 diabetes. The ADDITION-study is an ongoing study encompassing three countries, The Netherlands, England and Denmark. In Denmark, the study is represented in five counties, Aarhus, Copenhagen, Ringkoebing, Ribe and South Jutland counties. In this thesis, the effect of “Motivational interviewing” was evaluated in a cluster-randomised controlled trial carried out in the counties of Aarhus and Copenhagen, Denmark, 2001. This PhD thesis is a part of the ADDITIONstudy. It specifically explores the effect after one year of “Motivational interviewing” on newly diagnosed Type 2 diabetes patients detected by screening. This thesis focuses on whether GPs using “Motivational interviewing” can increase adherence to and effect of intensive treatment of Type 2 diabetes patients risk profile, thus reaching treatment goals. The concept of “Motivational interviewing” is introduced in Chapter 1, which also offers a summary of the use of this concept in research and practice and a presentation of the rationale why “Motivational interviewing” was chosen as the means of intervention. The aim of the PhD study is presented at the end of Chapter 1. Chapter 2 features a review of previous research on “Motivational interviewing” and its implications for practice and a meta-analysis on its effect. In Chapter 3 the effects of a training course in “Motivational interviewing” for general practitioners (GPs) are presented. The chapter addresses the questions whether the GPs aquired the methods of “Motivational interviewing” and if they used “Motivational interviewing” in their daily work. The next step focused on the effect of “Motivational interviewing” on patients lifestyle and behavioural change. Chapter 4 hence addresses the questions whether the GPs’ use of “Motivational interviewing” changed the patients’ contemplation of changing behaviour and if they did, indeed, change lifestyle behaviour. Finally, the effects of “Motivational interviewing” on patients’ risk profile and adherence to intensive treatment are outlined in Chapter 5. Chapters 6 to 9 offer a comprehensive and more general discussion of the methods used and the results presented in the articles, adding perspective to the research questions posed. Finally, Chapters 10 and 11 present English and Danish summaries. References used throughout the thesis are listed in citation order. Appendices provide an outline of the study flowcharts, the educational programme of “Motivational interviewing” and the questionnaires and case record forms in Danish (Appendix A-D).

III Motivation After my graduation from the University of Aarhus in 1998, I began my postgraduate career as a house officer. At this time I came into contact with the Department of General Practice while doing a small research project. During this project, I felt that the department had pleasant, productive and appealing atmosphere. However, I started as a senior house officer at the Department of Paediatrics, Skejby Hospital, where I was much inspired by the clinical work with children. I found myself standing with “one leg in two worlds”, General Practice or Paediatrics. This dilemma was put into perspective by my family situation as a husband and father of two children, Johan and Astrid. The challenge was to combine this wonderful family life with a productive and meaningful, clinical career and a PhD presented itself as a natural solution. The Department of General Practice proposed a project on “Motivational interviewing”. I had a meeting with Professor Carl-Erik Mabeck, my mentor in “Motivational interviewing”, and was intrigued by the possibilities of “Motivational interviewing” and the lack of research in this field. This was a method which, if it proved effective, could be used in both General Practice and in Paediatrics. After having caught up on the subject of “Motivational interviewing”, I decided that this was the right area for me to do further research in and began my PhD project. Acknowledgements The study would never have succeeded had it not been for the tremendous support I have received from my colleagues, from research funds and from my family. My colleagues in general practice in the County of Aarhus and the County of Copenhagen have involved themselves strongly in the project and accepted to be randomized and then undertaken all the hard work of attending courses, implementing the methods and recruiting the patients to the project. I am truly grateful for their participation and support for this project. I would also like to thank the practice staff and all the patients who spent much time filling in the questionnaires and case record forms. I am indebted to my supervisors, Professor Bo Christensen for being there all the time during the study, Associate Professor Annelli Sandbæk for having paid close attention and for having the “feel” of the project in its different phases, Professor Torsten Lauritzen and Professor Knut BorchJohnsen for their work launching and supporting the ADDITION-study. Finally, I am greatly indebted to my mentor Professor Carl-Erik Mabeck for sharing his profound knowledge on “Motivational interviewing”, his guidance and willingness to provide the right amount of inspiration and motivation when needed. I owe my sincere thanks to the flourishing research atmosphere at the Department and Research Unit of General Practice. My research colleagues have been helpful in constructive discussions, in practical matters of all kinds. I would also like to thank Hans Christian Kjeldsen and Kaare Mai for good company, our discussions in the office on everything else than research. The help provided by all the partners in the PhD project, the ADDITION-study, from the County Health Service, the Department of Health Insurance and all the laboratories on the hospitals has been exceptional, as has their aid in data retrieval and assistance in sorting out problems encountered during the study. The choice and use of statistical methods for data analysis was, of course, an interesting challenge, and I owe my special thanks to the Department of Biostatistics, Associate Professor, PhD Morten Frydenberg, who has been most helpful and patient with my queries and questions. IV I appreciate all the help that I received from the secretaries, Eva Therkildsen and Helle Hjort Pedersen at the Department of General Practice, Karen Wolsing, Ynna Margot Nielsen and Inge Krogh at the ADDITION-study, Elsebeth Schreiber at the Specific Training for General Practice and Birthe Brauneiser and Eva Højmark Pedersen at the Research Unit of General Practice. I am greatly thankful for the assistance provided by Bjarne Benner Svendsen, Lars Venge Olesen and Tonni Juul Hansen in relation to designing questionnaires, handling the retrieval of data and the database, solving all technical problems at hand and keeping virus, worms and other creatures out of my computer. I acknowledge the linguistic help of Professor Morten Pilegaard in revising the text. I owe a dept of gratitude to the Department of General Practice for housing me and for helping me administer the project economy. Considerable financial support was essential for the implementation of the study. The PhD study is funded by The Danish National Research Foundation for General Practice, the Danish Medical Association Research Fund, the Diabetes Associations foundation for Scientific Research. Furthermore the PhD study could not have been carried through without financial support given to the ADDITION study DK by: The National health service in the counties of Copenhagen, Aarhus, Ringkøbing, Ribe, South Jutland, all in Denmark. The Danish National Research Foundation for General Practice, Danish Centre for Evaluation and Health Technology Assessment, The Aarhus University Research Foundation, Novo Nordic Foundation. Unrestricted grants from Novo Nordic AS, Novo Nordic Scandinavia AS, ASTRA Denmark, Pfizer Denmark, GlaxoSmithKline Pharma Denmark, SERVIER Denmark A/S, HemoCue Denmark A/S. Finally, I am greatly indebted to my family. My father has provided eminent support during the study. My father has the ability to grasp all aspects of a problem, keep an overview, and yet still focus on how to solve each of the specific problems. My mother and sister have kept me going with their loving support and positive attitude. My children give me their unconditioned love and make me believe everything is possible in this world. My wife, Dorte, has inspired me in many parts of the project phases and I have enjoyed her ultimate confidence in my capabilities. I can only hope that I will be able to return this some day.

CASE RECORD FORMS IN DANISH USED IN THE STUDY X Chapter 1 General introduction 1 The concept of “Motivational interviewing” In this thesis “Motivational interviewing” as a concept is based on the definition of Miller and Rollnick presented in their book “Motivational interviewing, preparing people to change addictive behaviour”, 2002 1;2. Miller and Rollnick defined ”Motivational interviewing” as a “directive, client-centred counselling style for eliciting behaviour change by helping clients to explore and resolve ambivalence”. The concept of “Motivational interviewing” evolved from experience with the treatment of alcoholism and was described by Miller in 1983 3. This early experience developed into a coherent theory and detailed description of clinical procedures was provided in Miller and Rollnick (1991) 1, a work which was recently revised (2002) 2. Miller and Rollnick’s theory also draws inspiration from Carl Rogers’ work on non-directive counselling and behavioural change theory described in 1951 4. Previous research and the use of the term or concept “Motivational interviewing” has made it a more comprehensive concept that also often includes aspects from other psychological models of behaviour change and different approaches to the patient-doctor relationship. These new conceptual elements border on “Motivational interviewing”, and some even rest on the same theoretical foundation. However, in important respects, they are not coherent with the core concept of “Motivational interviewing” formulated by Miller and Rollnick. Description of the concept of “Motivational interviewing” “Motivational interviewing” is based on a characteristic counselling style including different techniques used in the patient-doctor relationship. The examination and resolution of ambivalence is the central purpose in non-directive counselling. However, the counsellor is intentionally directive in pursuing this goal. “Motivational interviewing” is a particularly way of helping clients recognize problems and change their behaviour accordingly. It is considered particularly useful with patients who are reluctant to change or ambivalent about changing their behaviour. The strategies of “Motivational interviewing” are more persuasive than coercive, more supportive than argumentative, and the overall goal is to increase the client’s intrinsic motivation so that change arises from within rather than being imposed from without 2. The spirit and characteristics of “Motivational interviewing” is captured in the following key points 2. 1. Motivation to change is elicited from the client, and not imposed from without. Other motivational approaches have emphasised coercion, persuasion, constructive confrontation. Such strategies may have their place in evoking change, but they are quite different in spirit from “Motivational interviewing” which relies upon identifying and mobilising the client's intrinsic values and goals to stimulate behaviour change. 2. Ambivalence takes the form of a conflict between two courses of action (e.g. indulgence versus restraint), each of which has perceived benefits and costs associated with it. The counsellor's task is to facilitate expression of both sides of the ambivalence impasse, and guide the client toward an acceptable resolution that triggers change. The specific strategies of “Motivational interviewing” are designed to elicit, clarify, and resolve ambivalence in a client-centred and respectful counselling atmosphere. 2 3. The counselling style is generally a quiet and eliciting one. More aggressive strategies, sometimes guided by a desire to "confront client denial," easily slip into pushing clients to make changes for which they are not ready, and therefore will not accommodate afterwards. 4. Readiness to change is not a client trait, but a fluctuating product of interpersonal interaction. Resistance and "denial" are seen not as client traits, but as feedback regarding counsellor behaviour. Client resistance is often a signal that the counsellor is assuming greater readiness to change than is the case, and it is a cue that the counsellor needs to modify motivational strategies. 5. Eliciting and reinforcing the clients in their motivational behaviour towards problem recognition, concerns, desire, intention, responsibility and ability to change. The client’s belief in the ability to carry out and succeed achieving a specific goal is essential. 6. The therapeutic relationship is more like a partnership or companionship than expert/recipient roles. The counsellor respects the client’s autonomy and freedom of choice and consequences regarding his or her own behaviour. 7. “Motivational interviewing” is not merely a set of techniques that are applied in treatment of clients. It is an interpersonal style, not restricted to formal counselling settings. It is a subtle balance of directive and client-centred components shaped by a guiding philosophy and understanding of what triggers change. Use of “Motivational interviewing” in research and practice “Motivational interviewing” is a counselling style and a method that is both rather well documented and scientifically tested, and it is viewed as a useful intervention strategy for changing behaviour5. It has been used and evaluated internationally especially in the last decade, in relation to the following main areas: 1) addiction (alcohol abuse and drug addiction), 2) change in lifestyle (smoking cessation, weight-loss, physical activity, asthma and diabetes treatment), and 3) adherence (to treatment and to control, encounters of follow-up, counselling meetings). “Motivational interviewing” has been deployed by various health care providers, including psychologist, doctors, nurses, dieticians and midwifes. However, current studies have focused on its effect in hospital settings with no or little attention to how the methods could be implemented and applied afterward in the daily clinical work especially in general practice. A few studies have been conducted in a clinical setting allowing to continue the process of using “Motivational interviewing” in daily clinical work after project termination 6-10. This thesis explores the effect of “Motivational interviewing” in general practice. “Motivational interviewing” has only recently been introduced in Denmark, but its use has been rising over the past years and it has been deployed in different scientific and clinical settings. Thus, in 2000 the Danish College of General Practitioners issued an introduction booklet on “Motivational interviewing” 11, which was mailed to all members of the Danish Medical Association. Furthermore, a Danish book on the subject written by Professor Carl Erik Mabeck was issued in more than 10000 copies 12 and more than 30 residential courses in “Motivational interviewing” have been conducted by Professor Carl Erik Mabeck since. These courses attracted mainly nurses, however, a number of GPs also attended the courses with a view to use the methods in general practice. Thus, a significant effort has been made in order to enhance the use of “Motivational interviewing” in Denmark. However, no research on the effect of this effort has so far been attempted. 3 The ADDITION-study The ADDITION-study, Anglo-Danish-Ducth study of intensive treatment in people with screendetected diabetes in primary care was developed and implemented in cooperation between the Department of General Practice and the Steno Diabetes Centre. The ADDITION-study investigates the effects of screening and intensive treatment, including poly-pharmacological treatment and behaviour change, in patients with Type 2 diabetes in general practice (as shown in Figure 1, Appendix A) 13. The ADDITION-study includes Type 2 diabetes patients detected by screening treated by a target-driven approach to intensive treatment including behavioural change and it has a follow-up period of 5 years. It is a large-scale study in general practice of a highly prevalent disease. The ADDITION-study is an ongoing study encompassing three countries, The Netherlands, England and Denmark. In Denmark, the study is represented in five counties, Aarhus, Copenhagen, Ringkoebing, Ribe and South Jutland counties. In this thesis effect of “Motivational interviewing” was evaluated in a cluster-randomised controlled trial carried out in the counties of Aarhus and Copenhagen, Denmark, 2001. This PhD thesis is a part of the ADDITION-study. It specifically explores the effect after one year of “Motivational interviewing” on newly diagnosed Type 2 diabetes patients detected by screening. This thesis focuses on whether GPs using “Motivational interviewing” can increase adherence to and effect of intensive treatment of Type 2 diabetes patients risk profile, thus reaching treatment goals. Aim of PhD thesis The overall aim of this PhD thesis was to evaluate the effect of a course in “Motivational interviewing” on intensive treatment of Type 2 diabetes patients detected by screening in general practice. Furthermore, the PhD study aimed at evaluating: 1. The effectiveness of “Motivational Interviewing” as an intervention tool in previous randomised controlled clinical trials (RCT) and to identify factors shaping outcomes in the areas reviewed. 2. In which way a 1½-day course in “Motivational interviewing” and subsequent follow-up meetings influenced the GPs’ professional behaviour. 3. If the GPs having participated in a course in “Motivational interviewing” found the method applicable and useful in general practice. 4. If “Motivational Interviewing” in general practice can improve patients’ a) contemplation and readiness to change behaviour, b) their actual change in patient behaviour, and c) their beliefs about Type 2 diabetes treatment. 5. If a course in “Motivational interviewing” for GPs can improve the risk profile of Type 2 diabetes patients detected by screening. 4 Chapter 2 Motivational interviewing: a systematic review and meta-analysis. Rubak S, Sandbaek A, Lauritzen T, Christensen B. British Journal of General Practice. Accepted 2004. 5 Abstract Background: ”Motivational Interviewing” is a well-known, scientifically tested method of client counselling developed by Miller and Rollnick and viewed as a useful intervention strategy in treatment of lifestyle behaviour and disease. Study design: A systematic review and a meta-analysis of randomized controlled trials (RTCs) using “Motivational Interviewing” as intervention. The aim is to evaluate the effectiveness of “Motivational Interviewing” in different areas of disease and to identify factors shaping outcomes. Methods: A systematic literature search in 16 databases produced after selection criteria 72 RCTs, the first published in 1991. A quality assessment was made with a validated scale. A meta-analysis was performed as a generic inverse variance meta-analysis. Results: Meta-analysis showed significant effect (95% CI) of “Motivational Interviewing” for combined effect estimates for Body Mass Index (BMI), total serum-cholesterol, systolic blood pressure, blood alcohol concentration, standard ethanol content, while combined effect estimates for cigarettes per day and for HbA1c were non-significant. “Motivational Interviewing” had significant and clinically relevant effect in app. 3 out of 4 studies with equal effect on biological (72%) and psychological diseases (75%). Psychologists and medical doctors obtained an effect in app. 80% of the studies, while other health care providers obtained an effect in 46% of the studies. When using “Motivational Interviewing” in brief encounters of 15 min., 64% of the studies showed effect. More than one encounter with the patient ensures effect of “Motivational Interviewing”. Conclusion: We conclude that “Motivational Interviewing” in a scientific setting outperforms “traditional advice giving” in the treatment of a broad range of behavioural problems and diseases. We now need large scale studies to prove, that “Motivational Interviewing” can be implemented into daily clinical work in primary and secondary health care. 6 Introduction The concept of “Motivational Interviewing” evolved from experience with treatment of alcoholism, and was first described by Miller in 1983 3. This basic experience was developed into a coherent theory and detailed description of clinical procedures is provided by Miller and Rollnick (1991) 1, who defined “Motivational Interviewing” “as a directive, client-centred counselling style for eliciting behaviour change by helping clients to explore and resolve ambivalence”. Miller and Rollnick’s theory also draws inspiration from Carl Rogers’ work on non-directive counselling described in 1953 4. The examination and resolution of ambivalence is the central purpose in nondirective counselling, and the counsellor is intentionally directive in pursuing this goal. “Motivational Interviewing” is a particular way of helping clients recognize and do something about their present or potential problems. It is viewed as particularly useful with clients who are reluctant to change or ambivalent about changing their behaviour. The strategies of “Motivational Interviewing” are more persuasive than coercive, more supportive than argumentative, and the overall goal is to increase the client’s intrinsic motivation so that change arises from within rather than being imposed from without2. The spirit of “Motivational Interviewing” is captured in the key points in Appendix 1 2. Appendix 1. Miller & Rollnick: “Characteristics of the motivational interviewing” 1. “Motivational Interviewing” relies upon identifying and mobilizing the client's intrinsic values and goals to stimulate behaviour change. 2. Motivation to change is elicited from the client and not imposed from without. 3. “Motivational Interviewing” are designed to elicit, clarify, and resolve ambivalence to perceive benefits and costs associated with it. 4. Readiness to change is not a client trait, but a fluctuating product of interpersonal interaction. 5. Resistance and "denial" is often a signal to modify motivational strategies. 6. Eliciting and reinforcing the client’s belief in ability to carry out and succeed in achieving a specific goal is essential. 7. The therapeutic relationship is a partnership with respect of client autonomy. 8. “Motivational Interviewing” is both a set of techniques and counselling style. 9. “Motivational Interviewing” is directive and client-centred counselling understanding and eliciting behaviour change. “Motivational Interviewing” is broadly applicable in the management of diseases which to some extent is associated with behaviour 6-77. It has been used and evaluated in relation to alcohol abuse, addiction to drugs, smoking cessation, weight-loss, adherence to treatment and follow-up, increase of physical activity, asthma treatment and diabetes treatment, “Motivational Interviewing” has been deployed by various health care providers, including, among others, psychologist, doctors, nurses and midwifes6;8;30;38;54;62. This review provides an overview of the areas in which “Motivational Interviewing” has been applied. The aim of this review is to evaluate the effectiveness of “Motivational Interviewing” as an intervention tool in randomised controlled clinical trials (RCT) and to identify factors shaping outcomes in the areas reviewed. 7 Methods Search strategy The following electronic libraries were searched according to the Cochrane Collaboration’s search strategy for randomised controlled trials for each database: the Cochrane Central Register of Controlled Trials on the Cochrane Library (issue 4, 2002); MEDLINE (1966 to January, 2004); EMBASE (1974 to January, 2004); and PsychINFO, including PsychLIT (1967 to January, 2004), Cancerlit (1966 to January, 2004), Science Direct/ISI, including scisearch and social scisearch (1972 to January, 2004), Sociological abstracts (1963 to January, 2004), social services abstracts (1980 to January, 2004), EBSCO net research databases (1980 to January, 2004), CSA/Econ lit index (1969 to January, 2004), Biological science (1982 to January, 2004), Biological abstracts (1969 to January, 2004), AIDS and cancer research abstracts (1982 to January, 2004), AskERIC (1966 to January, 2004), BIOSIS PREVIEWS (1969 to January, 2004), ABI-/INFORM (1971 to January, 2004). The following search terms were used for MEDLINE and adapted for each other database: “motivational interviewing”, “motivational behaviour”, “behaviour/motivational interviewing”, “Behaviour change”, “Motivational change” and “Behaviour change/motivational interviewing”. The proceedings of conferences during 1997 to 2004 on diabetes (American Diabetes Association, Diabetes UK [formerly British Diabetic Association], European Association for the Study of Diabetes, International Diabetes Federation) were searched under psychological, educational, or behavioural headings for reports of any trials using motivational interviewing. The reference lists of included studies and reviews were searched for additional studies. If an included trial did not supply sufficient data needed for the meta-analysis, we tried to obtain data approaching the authors and the same time asking for data from unpublished trials. The search process was performed by first author. Figure 1 shows the progress of RCTs through the review. 8 Figure 1. Flowchart of progress of RTCs in the review. Potentially relevant studies based on key-word search in 16 databases. N = 15516 Studies excluded because of not being RCT N = 15174 RCTs retrieved for more detailed evaluation. N = 342 Studies excluded because of overlap of publications between databases. N = 188 Potentially appropriate RCTs to be included in the review. N = 154 Studies excluded because of intervention not being based on Miller & Rollnick. N = 88 RCTs included in the review. N = 72 RCTs included in the review with direct effect measures. N = 42 RCTs included in the review with direct objective measures and statistical data entering the Meta-analysis. N = 19 9 Selection In Figure 2, a Funnel plot is presented 82. RCTs included in the review were using “Motivational Interviewing” defined according to Miller & Rollnick as intervention 2 regardless of the context of client counselling. Excluded were RCTs in which there were no or minimal description of the methods of “Motivational Interviewing” and the modes of delivery. We only included studies where “traditional advice giving” used to help and advice clients served as control. “Traditional advice giving” is used as an expression for doctorcentred approach, i.e. the GP define the patients’ problem from a biomedical perspective and does not at all include the patient perspective on the matter, thus giving advice accordingly 12;83. Figur 2. Funnelplot of RCT´s using motivational interviewing as intervention 1000 800 600 Sample size (n) 400 200 0 -2 -1 0 1 2 3 Log(Effect-estimat) A Funnel plot is a simple scatter plot of the treatment effects estimated from individual studies (on the x axis) against some measure of each study’s simple size (on the y axis). A logarithmic scale ensures that effects of the same magnitude but opposite directions are equidistant. In the absence of bias the Funnel plot should resemble a symmetrical inverted funnel or a triangle. Qualitative data synthesis Quality assessment of each of the resulting 72 RCT was assessed by the first author. Quality assessment was made with a validated scale 84;85 and individual components known to affect estimates of intervention efficacy 86. The scale consisted of three items pertaining description of randomisation, masking, dropouts and withdrawals in the report of an RCT. The scale ranged from 0 to 5, with higher score indicating better reporting. The individual components assessed the adequacy of reporting of randomisation, allocation concealment and double-blinding. High-quality trials scored minimum of 2 out of 5 86. 10 Validity assessment, Data extraction The abstracts of studies identified by electronic searches was assessed by first author and extracted onto a data extraction form. Confirmation of outcome measures and clinically relevant goals was assessed by all the authors. All studies were examined to assess the clinical relevance of their goals and outcome measures to client treatment, for example HbA1c as outcome-measure and study goal as a 1% reduction in HbA1c. Table 1 (only published in the electronic version of the paper), shows the studies with objective outcome measures and the assessment of clinical relevance and statistical significant effect. Furthermore, for a study to be classified as showing effect, the recorded effect had to be statistically significant. When a study is classified as demonstrating effect, it therefore enjoys both a statistically significant effect and a clinically relevant effect to client treatment. Quantitative data synthesis Statistical data analysis was conducted in SPSS (version 11.0). A descriptive summary of the information extracted from included trials was made. The meta-analysis was carried out using Excell 2003 and STATA (version 8). The Meta-analysis conforms to the Cochrane Reviewers Handbook 82. The meta-analysis is performed as a generic inverse variance meta-analysis, in which we assume homogeneity between study estimates. The assumption of homogeneity is based on the confidence intervals for the study estimates having large overlap, which indicates homogeneity 82. The meta-analysis calculates combined estimates of effect with standard error and 95 % confidence interval. The meta-analysis is based on the RCTs which included effect measures on patient outcome and submitted statistical data. Study characteristics The following variables were extracted for analysis: 1. Characteristics of the intervention: - Ways of delivery (in office, out of patient clinic, at home, by telephone, etc.) - Duration of intervention (time used in one counsellor-client encounter) - Number of intervention encounters (counselling encounter) - Practising counsellor (psychologist, doctor, nurse, midwife, etc.) 2. Design of study (study group and follow-up): - Number of participants - Follow-up period - Inclusion criteria (population, selection, etc.) 3. Area of intervention: - Adherence to treatment of diseases - Adherence to life style changes 2. Outcome measures: - Direct indicators (health outcome, e.g. B-glucose, B-cholesterol, utilization of health care services, e.g. length of hospital stay, etc.) - Indirect indicators (subjective report, self-assessment, questionnaires) Results Trial flow The systematic review using RCTs progressed as shown in flowchart, Figure 1. 11 Validity assessment, Data extraction Table 1 (only published in the electronic version of the paper), shows studies with objective outcome measures, clinical relevance, statistically significance and published statistical data.

The meta-analysis show significant effect (95% CI) of motivational interviewing for combined effect estimates for Body Mass Index (BMI), total serum-cholesterol, systolic blood pressure, blood alcohol concentration, standard ethanol content, while combined effect estimates for cigarettes per day and for HbA1c are non-significant (Table 3).

High-quality trials scored a minimum of 2 out of maximum possible score of 5. Out of 72 RCTs, 50 were assessed to 3 points, 21 assessed to 2 points and one RCT was assessed to 1 point. Study characteristics An effect of “Motivational Interviewing” was demonstrated in 74% (53/72) of the RCTs. With regard to adverse effects of motivational interviewing none of the publications reported any adverse effects nor did they explicitly aim to report this. In no studies have “Motivational Interviewing” shown to be harmful or having any kind of adverse effects. A total of 94% (68/72) of the RCTs used individual interview. Of the remaining four studies, three used group therapy; one study used a telephone interview, but showed no effect. The median duration in all the studies of an individual counselling encounter was estimated to 60 min. (range: 10-120 min.). Among the studies using encounters of 60 min., 81% (26/32) showed an effect. Out of eleven studies using less than 20 min. per encounter 64% (7/11) showed an effect. The likelihood of an effect rose with the number of encounters. Hence, an effect was demonstrated in 40% (10/25) of studies with one counselling session, but in 87% (13/15) of studies with more than five encounters. The studies had an estimated median follow-up period of 12 month (range: 2 months to 4 years). A prolonged follow-up period increased the percentage of studies showing effect. Thus, 36% (4/11) of studies with a 3-month follow-up period ascertained an effect compared with 81% (26/32) among studies allowing a 12month or longer follow-up period. Health care providers as counsellor were: psychologists 55% (42/76), medical doctors 30% (23/76) and other health care providers (nurses, midwives, dieticians, etc.) 15% (11/76). Medical doctors obtained an effect of “Motivational Interviewing” in 83% (19/23) of the studies, where psychologists obtained an effect in 79% (33/42) of the studies. Other health care providers obtained an effect in 46% (5/11) of the studies. Intervention targeted alcohol abuse, treatment of clients with psychiatric diagnoses and different aspects of addiction in 47 of 72 studies, and “Motivational Interviewing” outperformed “traditional advice giving” in 75% (35/47) of these studies. “Motivational Interviewing” targeted biological problems, i.e. weight loss, lowering of lipid levels, increasing physical activity, diabetes, asthma and smoking cessation in 25 of 72 studies and had an effect in 72% (18/25). Smoking cessation studies alone reported an effect in 67% (8/12), where studies involving treatment of diabetes, asthma, and weight-related problems reported an effect in 77% (10/13). All studies used indirect measures, e.g. questionnaires. 46% (33/72) also used direct effect measures (health outcome, direct/indirect indicators, utilization of health care services). An effect of “Motivational Interviewing” was obtained in 75% of the studies elicited in terms of direct measures (33/44) and in 74% of the studies elicited in terms of indirect outcome measures (53/72). Discussion Main findings This review documents that “Motivational Interviewing” in a scientific setting effectively helps clients change behaviour and that it outperforms “traditional advice giving” in approx. 80% of the studies. No studies have reported “Motivational Interviewing” to be harmful or having any kind of adverse effects, however no study did explicitly aim to report this. 17 Strength and limitations Publication bias is often a well known problem. However a Funnel-plot, Figure 2, of all the studies within the research area of motivational interviewing indicates publication bias to be nonsignificant. Furthermore a methodological quality rating 84-86shows that except one study, all the RCTs in this review has a high methodological quality. All studies in the meta-analysis demonstrate a positive effect or tendency although not all studies show a significant effect of “Motivational Interviewing”. However the meta-analysis was only performed on the 19 studies (out of 42), which stated effect measures on patient outcome and statistical data needed for the meta-analysis in the article or delivered these data afterwards on request. Of the remaining 23 studies, 17 concluded significant effect of “Motivational Interviewing” and 6 showed non-significant effect. These remaining studies did not deliver the statistical data in the article or afterwards needed for metaanalysis. However, in the light that a vast majority (33 out of 42) of the RCTs with effect measures on patient outcome, concluded significant effect of “Motivational Interviewing”, we believe a potential selection bias to be non-significant and the results of the meta-analysis to be valid. Detailed findings The meta-analysis shows significant effect of motivational interviewing for combined effect estimates of Body Mass Index (BMI), total serum-cholesterol, systolic blood pressure, blood alcohol concentration, standard-ethanol content (Table 3). In particularly the magnitude of the decrease of BMI, systolic blood pressure, blood alcohol concentration decrease and standard ethanol content is of clinical relevance and imply that motivational interviewing can and should be used. The significant decrease for the combined effect estimate of total serum-cholesterol is of less clinical importance. However viewing an effect as clinical important or not, it is imperative to keep in mind that “Motivational Interviewing” is based on making the patients themselves aware of potential “space” for change in behaviour resulting in improved health parameters, which means that small changes also may be of interest, if they are the beginning of a changing process for the patient. The “nature of changes” from the patient is almost always related to both the adherence to prescribed medication and to what changes the patient make in life style. However effect of “Motivational Interviewing” in some problem areas e.g. weight loss, smoking cessation, is primarily mediated through change of own habits, whereas effect on asthma primarily comes from adherence to prescribed medication. This meta-analysis provides evidence of significant effect of motivational interviewing on many different areas of intervention. The review has shown that “Motivational Interviewing” can be effective even in brief encounters of only 15 min and that more than one encounter with the patient increases the likelihood of effect 6; 7;14;15;24;43;44;45;49;51. This review sheds new light on the assumption that the effectiveness of “Motivational Interviewing” depends upon the counsellor’s profession. The effect was not related to the counsellor’s educational background as medical doctor or psychologist. Hence, there was no statistical significant difference in the percentage of studies obtaining an effect of “Motivational Interviewing” whether it was performed by psychologists, psychiatrists, physicians or general practitioners. Utilization of “Motivational Interviewing” probably depends on other aspects like duration and number of client-counsellor encounters. However, it would be reasonable to speculate that aspects like training and experience with “Motivational Interviewing” methods and clientcounsellor relationship also influence the effectiveness, even if this cannot be shown in this review. Five studies involved other health workers, e.g. nurses, midwifes and dieticians as counsellor, and 18 another six studies partly involved other health workers in the counselling encounter 6;17;18;22;27;30;32;38;62;70;72 . Only five of these eleven studies found “Motivational Interviewing” to be effective 6;30;38;62;72. This may, to some extent, be explained by the design of these studies as most of them reported on the effect of only one encounter, had a follow-up period shorter than three months and began with difficult subjects like HIV-positive addicts changing life style. Implications for future research This review underscores the crucial importance of the “Motivational Interviewing” setting and the study design for obtaining an effect. Thus, a follow-up period shorter than three months increases the risk of failure counselling, probably due to “lack of intervention” 22; 27;28;32;34;40;65. Another important aspect was the use of indirect measures versus direct measures. This review showed that an effect of “Motivational Interviewing” can be demonstrated by indirect measures like questionnaires but also direct effect measures like blood pressure, blood glucose, weight, length of hospital-stay, etc. When it is possible to measure effect by epidemiological as well as clinical direct measures and to capture effect by clinical endpoints, this should be done to ensure the reliability of the results. The optimal design would match the specificity and reliability of direct measures with the in-depth qualitative perspective of indirect measures, e.g. questionnaires. Furthermore in the optimal design, it is imperative that future studies make an effort to describe precisely how “Motivational Interviewing” education is performed and how we “use” the methods in client counselling, allowing us all to learn more about how to increase and maximise its effect. Implications for practice The review shows that “Motivational Interviewing” has been used in treatment of various life styles and diseases, psychological as well as biological. The review shows that app. 75% of the studies do obtain effect no matter biological or psychological disease, which is supported by the meta-analysis. We may therefore now argue that “Motivational Interviewing” is not limited in any way to counselling of a small group of selected clients, but can be used in the treatment of a broader area of diseases which to some extent is influenced by behaviour. When viewed in combination with no apparent harmful effect and no reported adverse effects of “Motivational Interviewing”, it suggests a method with an important potential effect, which patients very well may benefit from. Conclusion The review and meta-analysis affords the conclusion that “Motivational Interviewing” in a scientific setting outperforms “traditional advice giving” in the treatment of a broad range of behavioural problems and diseases. However evaluation of exact methods of “Motivational Interviewing” in a clinical setting is missing. We now need large scale studies both RCTs and qualitative studies on how to implement the methods of “Motivational Interviewing”, to prove, that it can be implemented into daily clinical work for health care providers and yield effect to the benefit of the patients. 19 20 Chapter 3 How does an education and training course in “Motivational interviewing” influence general practitioner’s professional behaviour. ADDITION Denmark. Rubak S, Sandbaek A, Lauritzen T, Borch-Johnsen K, Christensen B. British Journal of General Practice. Submitted 2004. 21 Abstract Background: ”Motivational interviewing” has been shown to be broadly usable in the management of behavioural problems and diseases. However, data concerning implementation and aspects regarding the use of ”Motivational interviewing” in general practice is missing. Aim: To evaluate general practitioners (GPs) conception of ”Motivational interviewing” in terms of methods, adherence to and aspects of its use in general practice after a course. Study design: The study involved three groups of GPs, two of which comprised a RCT concerning intensive treatment of newly diagnosed Type 2 diabetes patients detected by screening. These two groups were randomised to a course in ”Motivational interviewing”. The study also included a third group of GPs outside the RCT, who had two years previously received a similar course in ”Motivational interviewing”. Methods: The intervention consisted of a 1½-day residential course in ”Motivational interviewing” with ½-day follow-ups, twice during the first year. Questionnaire data from GPs were obtained. Results: We obtained a 100 % response-rate from the GPs in all three groups. The GPs trained in ”Motivational interviewing” adhered statistically significantly more to the methods than did the control group. More than 95 % of the GPs receiving the course stated that they had used the specific methods in general practice. Discussion/Conclusion: A course in ”Motivational interviewing” seems to influence GPs professional behaviour. Based on self-reported questionnaires, this study shows that the course provided GPs with skills that raised their confidence in using ”Motivational interviewing” for patient treatment. GPs found ”Motivational interviewing” to be more effective than “traditional advice giving”. Furthermore, the experienced GPs found that the method was not more time consuming than “traditional advice giving”. 22 Introduction The concept of “Motivational interviewing” evolved from experience with treatment of alcoholics and was described by Miller in 1983 3. The concept was developed into a coherent theory and a detailed description of the clinical procedures 1. ”Motivational interviewing” has been shown to be broadly usable in the management of behavioural problems and diseases 5. Hence, the method has been used and evaluated internationally especially in the last decade in relation to the following main areas 1) Addiction (Alcohol abuse and addiction to drugs), 2) Change in lifestyle (Smoking cessation, weight-loss, physical activity, asthma and diabetes treatment), and 3) Adherence (to treatment and to control, encounters of follow-up, counselling meetings) 5. The technique has been deployed by various health care providers, including psychologist, doctors, nurse’s and midwifes. Controlled trials in general practice have shown that it is an effective strategy in the treatment of different diseases 21;24;36;38;43;60;64. However, only very few studies have focused on how to implement and integrate “Motivational interviewing” in professional behaviour in daily work in general practice 87;88, and they have concluded that this strategy lends itself well to implementation in general practice. We found a need for evaluating whether the general practitioners (GPs) educated and trained in ”Motivational interviewing” actually used and adhered to the methods in their clinical work. The aim of this study was to evaluate 1) how a 1½-day course in “Motivational interviewing” including follow-up meetings influenced GPs professional behaviour, 2) whether GPs after a 1½day course found the method to be useful in general practice. 23 Methods Study group The study included three groups of GPs: Two groups participated in the ADDITION study 13, which is a multi-centre randomised controlled trial of a target-driven approach to intensive treatment of patients with Type 2 diabetes detected by screening. All practices registered at the County Health Insurance Registry in Aarhus County were 1. January 2001 invited to meetings about participation in the ADDITION-study. In Copenhagen County only practices located in the north and eastern part (7 municipalities) were invited, because screening for diabetes had already taken place in the remaining municipalities in the county in connection with the Inter99 study. In agreement with the County Health Insurance only 60 GPs were to be included per county at study onset, and primarily practices with more than one GP were included. No exclusion criteria for the GPs were applied and included GPs in the ADDITION study were randomised at practice level into a group giving standard care and an intervention group educated to intensive treatment including lifestyle intervention and poly-pharmacological treatment aiming for rigorous values of blood glucose, blood pressure and lipids in addition to anticoagulation treatment. This study included practices/GPs from the intervention group of the ADDITION study. These practices/GPs were sub-randomised into: an internal motivational group (IM-group) comprising GPs receiving a course with education and training in ”Motivational interviewing” and an internal control group (IC-group) comprising GPs receiving no formal education or training in ”Motivational interviewing”. The inclusion of GPs is shown in the flowchart, Figure 1. Randomisation within the ADDITION study was stratified by county (Copenhagen and Aarhus) and size of practices. GPs received education and training free of charge. This study included furthermore an external motivational group (EM-group). This group consisted of GP, who had attended the course in ”Motivational interviewing” two years before the start of the ADDITION study (20 GPs). This group was contacted externally to the ADDITION-study and was asked to answer the same questionnaire as GPs within the ADDITION-study, thus serving as a group of GPs with long-term knowledge of the use of “Motivational interviewing”. GPs in this group attended the training and paid all expenses themselves. 24 Figure 1.

IM-group: Internal motivational group receiving course in “Motivational Interviewing” EM-group: External motivational group receiving course in “Motivational Interviewing” 25 Method of intervention The courses in ”Motivational interviewing” for the GPs in the IM and EM groups were conducted by a single trained teacher, who had conducted several of these courses successfully. The teacher is the first author of ”Motivational interviewing ”, a manual from the Danish Scientific Society of General Practitioners (2000) 89 which together with “Motivational interviewing, preparing people to change addictive behaviour” (1991) 2 constituted the theoretical part of the course curriculum. Each course included 6-12 GP participants. Each session started with a short introduction to the methods of “Motivational Interviewing” followed by group discussions and training the methods involving a high level of participation in workshops and role-plays. The principal rules of “Motivational Interviewing” in relation to the patient-doctor relationship 2 were trained as was the use of the specific skills e.g. empowerment 90, use of the ambivalence 2, the decisional balance schedule 2, visual analogue scale 2 and stage of change 91 and reflective listening 2. The courses for the GPs in the IM group consisted of a 1½-day training sessions with half a day follow-up twice during the first year. Two years prior to the start of this study, the GPs in the EM group had participated in a course similar to that given the IM group. None of the GPs in either three groups had previously participated in courses in ”Motivational interviewing”. All GPs in the RCT (IM-/IC group) had participated in the same training courses in intensive treatment of Type 2 diabetes patients detected by screening. The training course lasted half a day and follow-up was performed as afternoon meetings twice every year. During these diabetes training sessions, it was stressed that GPs should act as counsellors for the patients, allowing treatment decisions to be based on a mutual understanding between the patient and the GP. Measurements No validated questionnaire was available for evaluating the courses in ”Motivational interviewing” and the GP’s conception of the methods, adherence to the technique and their actual use of ”Motivational interviewing”. The construct of the questionnaire was therefore designed based on 1) the theoretical knowledge about ”Motivational interviewing”, 2) the leading author’s knowledge from attending the course and 3) knowledge from the teacher and head of the course. The content of the questionnaire was divided into themes: “GPs reaction in specific patient cases”, “GPs preferred way of motivating change in patient behaviour” and “practicability of ”Motivational interviewing” and aspects concerning the GP’s use of the technique in their daily clinical work”. The questionnaire was evaluated and pilot tested by GPs and lay people within and outside the Department of General Practice, University of Aarhus. The validation process included ensuring that questions were not to be misunderstood, that questions in total covered the themes while at the same time not overlaying each other and that answering categories was sufficient to discriminate between different answers. In order to evaluate the GP’s use of ”Motivational interviewing”, the following 4 questions were asked: Q1: What do you do, when the patient obviously does not follow your advice? Q2: What do you do, when you sense that the patient does not want to follow your advice? Q3: What do you do, when the patient’s conception of good health and actual life style are inconsistent? Q4: What do you do, when you aim at motivating change in patient behaviour? For Q1-3 the GPs should respond to 9 different possible reactions (Figure 2) on a 5-item Likert scale (1=full agreement, 5=total disagreement). With regard to question 4, the GPs should respond to 8 different possible reactions (Figure 3) on a 5-item Likert scale indicating how often they used each possibility (1=always, 5=never). The possible reactions for Q1-4 were related to counselling style, using either ”Motivational interviewing” or “traditional advice giving”. 26 “Traditional advice giving” is used as an expression for doctor-centred approach, i.e. the GP define the patients’ problem from a biomedical perspective and does not at all include the patient perspective on the matter, thus giving advice accordingly 12;83. Figure 2. Questions (Q1-3) to evaluate how GPs used MI. Q1: What do you do, when the patient obviously does not follow your advice? Q2: What do you do, when you sense that the patient does not want to follow your advice? Q3: What do you do, when the patient’s conception of good health and actual life style are inconsistent? GP’s had to respond on a 5-item Likert scale to each of the following possible reactions: Explain the plan of treatment and care once again Explore further the patients abilities and possibilities for solving the problem Explain by arguments why it is important to follow the treatment once again Investigate if the patient believes that the treatment will help Make the patient tell about advantages and disadvantages of habits in relation to disease Inform further about the disease and treatment to pursuit the patient to a deal Tell further about the consequences if the treatment plan is not followed Make the patient summarize the agreed deal Ask about the patient’s expectations to what you can do in the actual situation of disease 5-item Likert scale: Fully agree=1, partly agree=2, not agree or disagree=3, partly disagree=4, totally disagree=5 Figure 3. Questions (Q4) to evaluate how GP’s used MI. Q4: What do you do, when you aim at motivating change in patient behaviour? GP’s had to respond on a 5-item Likert scale to each of following possible reactions: Reflective listening Preparing the patient of different treatment options before choosing the one Using accurate arguments for change of life-style to emphasize the consequences of sustained life-style Clarifying the treatment strategy in relation to time Emphasizing the patients resources Clarify what advantaged and disadvantages the patient sees in relation to disease and plan of treatment Showing patient empathy, support and respect Focusing on the positive sides of the patients habits in relation to the disease 5-item Likert scale: Always=1, Often=2, On occasion=3, Seldom=4, Never=5 27 The sum-scores for questions 1 to 4 were calculated to evaluate whether or not the GPs used the methods of ”Motivational interviewing” or “traditional advice giving”. “Questions” 1-4 were based on the responses to each possible reaction in Figure 2 and 3. The responses were first reversed in order to unify the direction of the response to each possible reaction. Then all the responses to the possible reactions to each question were added and divided by the number of items, thereby generating a mean response for each question. The method of sum-scoring questions has been used and validated in different settings 92-96. Questions 1-4 were given to all three groups of GPs, whereas the remaining questions regarding the practicability of ”Motivational interviewing” and aspects concerning the GP’s use of the technique in their daily clinical work (Tables 1-3) were given to the GPs in the motivational groups (IM-/EMgroup). Questionnaires were mailed to all three groups either one year (IM- and IC-groups) or threes years (EM-group) after the courses. Reminders were mailed two weeks later. Statistical method Statistical analysis of data was conducted in SPSS (version 11.0). All single variables containing data from a Likert scale were analysed by a non-parametric Mann Whitney test (Tables 2 and 3). All sum-score variables from questions 1-4 followed a normal distribution and consequently a Ttest was done. Results are either given as median and quartiles, simple percentages or as mean with 95% confidence interval (CI). A statistical significance level of 0.05 (two tailed) was used. Results Study sample characteristics A flowchart for participating practices and GPs is shown in Figure 1. In all, 48 practices (65 GPs) were included. Twenty-syven practices (36 GPs) were randomised into the IM-group and 21 practices (29 GPs) into the IC-group. Two practices including 6 GPs (all in control group) dropped out after randomisation. We obtained a 100 % response rate to the questionnaire from the GPs in all three groups. All GPs in the IM- and EM-group participated in the ”Motivational interviewing” courses, and less than 10% were absent from the ½-day follow-up meetings. The GPs had an average age of 53 years, were male in 2 out of 3, and had an average of 1500 patients in their practice with no significant differences between the study groups. Study data and analyses The motivational groups (IM-/EM-group) seemed to adhere more to ”Motivational interviewing” than the control group (IC-group) as there were no significant differences between these two groups, as opposed to between the motivational groups and the control group in terms of the GP’s responses to different doctor-patient situations (Table 1). 28 Table 1.

Evaluation by mean sum-scores from the possible reactions (Tables 1 and 2) to the following questions: Q1: What do you do, when the patient obviously does not follow your advice?

The responses from GPs in the control group to the possibilities raised in Figures 2 and 3 showed that they used some elements from both strategies, viz.”Motivational interviewing” and using “traditional advice giving”. A majority (79-100%) of GPs in the motivational groups (IM-/EMgroup) stated that they had used the different elements of ”Motivational interviewing” after the course (Table 2). The GPs in the IM-group agreed statistically significantly more than the GPs in EM-group in the usability of the visual analogue scale and the decisional balance schedule, whereas no differences were seen concerning the usability of the other elements (Table 2).

Four statistically significant differences appeared between the IM- and EMgroup.

The GPs in EM-group disagreed more than GPs in the IM-group in their awareness to questions concerning aspects of the use of ”Motivational interviewing” (possibilities 12-14, Table 3). Table 3.

Their professional behaviour in daily practice seemed to be changed in direction of the ”Motivational interviewing”. Strength and limitations The main strengths of the study are that 1) all GPs responded to the questionnaire, 2) all GPs in the IM-group attended the ”Motivational interviewing” courses, and 3) less than 10% GPs were absent from the follow-up meetings. In spite of the relatively small number of GPs in each group (20 to 31), significant findings between groups were found. Previous studies on ”Motivational interviewing” in general practice have proven an effect 21;24;36;38;43;60;64. However, only few studies have focused on how to implement ”Motivational interviewing” in the daily clinical work in general practice in such a way that it is ascertained that the method is used after study closure 87;88. They concluded that it despite barriers was possible to implement the use “Motivational interviewing” in general practice 87;88. We used questionnaires as measuring method on effect of a course in “Motivational interviewing” of GPs in general practice and obtained statistically significant changes between study groups. However, the sensitivity of this measuring method is low, when focusing on the GPs actual use and adherence to ”Motivational interviewing”. In order to enhance sensitivity of these aspects, external assessment was required, e.g. video-recordings. This was not possible in this study of 48 practices, and 65 general practitioners in two counties. The GPs in the internal groups (IM-/IC-group) were randomised into a RCT arm for ”Motivational interviewing”, whereas GPs in the EM-group had decided by themselves to participate in the course. Thus the GPs in the latter group were probably more motivated to obtain and use ”Motivational interviewing” than the former groups. However, both motivational groups (IM-/EMgroup) rated ”Motivational interviewing” the same way except that external group agreed more to the usefulness and the effect of ”Motivational interviewing” in general practice. The study suffer the limitation that GPs in the control group could have become familiar with ”Motivational interviewing” by personal initiative during the study period. Furthermore, GPs in the RCT (IM-/IC-group) received training in intensive treatment of Type 2 patients. During these diabetes training sessions, it was stressed that GPs should act as counsellors giving patients advice about how to reduce the risk of late diabetic complications and allow treatment decisions to be based on mutual understanding between the patient and the GP. This may have influenced the GPs in the control group, who in their response to the possibilities in Figures 2 and 3 indicated that they neither entirely used ”Motivational interviewing” or the “traditional advice giving”. However, some of their choices showed a tendency for adhering to ”Motivational interviewing”. These circumstances tend to reduce the differences between GPs in the IM-group and IC-group. In spite of this, statistically significant differences were found. This indicates that the course in ”Motivational interviewing” affected the GPs’ professional behaviour, thus, a relevant change for daily work in general practice. The intervention consisted of a course in ”Motivational interviewing” conducted by one person. Outcome is therefore highly dependent on this person’s teaching methods and capacity to train the 31 GPs. If several teachers had conducted the courses, this problem would have been diminished. The use of more teachers on different courses, however, might have introduced differences in learning and training outcome. We chose to use one teacher only because only very few can teach ”Motivational interviewing” in Denmark and the teacher had previously conducted several of these courses and was the leading author to the course curriculum. Detailed findings Of particularly interest was that the EM-group of GPs with three years of experience with ”Motivational interviewing” differed more in their evaluation of the usability of some of the specific methods than the IM-group of GPs with one year of experience. GPs in the IM-group evaluated methods like “visual analogue scale” and “decisional balance schedule” to be more usable in general practice than GPs in the EM-group (both methods being “straight forward” and easy to use). The GPs in the EM-group showed a tendency of rating “using the ambivalence” and “empowering” higher than the GPs in the IM-group. These methods demand that the GP is able to use the principal rules of ”Motivational interviewing” in all aspects. Hence, it seems if GPs in the EM-group integrated ”Motivational interviewing” in their patient-doctor relationship to a greater extent than GPs in the IM-group, thus, having obtained more confidence in using its more complex dimensions. Even though the GPs in the IM group were recruited by randomisation, their responses mirrored those of the GPs who participated by own choice (EM group). The results after 3 years in the IMgroup would probably be close to the present results of the EM-group. This is further supported by the fact that both groups evaluated ”Motivational interviewing” as suitable for general practice. However, the more experienced GPs in the EM-group expressed that the method was not more time consuming than “traditional advice giving”. The time-consuming aspect of ”Motivational interviewing” has previously been investigated by Rollnick et al in relation to smoking cessation reporting that an average consultation encounter lasted 9-10 min, which was acceptable to the GPs 36 . Furthermore, the GPs in the EM-group found the method was not difficult to adapt and use in patient-doctor relationship. The motivational groups found that ”Motivational interviewing” improved the patient-doctor relationship and that it was more effective than “traditional advice giving”. Stott et al performed a study on how GPs would react to new technologies and methods showing that GPs did adopt, accept and use new methods when they facilitated solutions to problems in patient-doctor relationship 97. The difference between the motivational groups could indicate that it takes more than one year to integrate ”Motivational interviewing” into daily clinical practice. Implications for future research Doherty et al wrote addressed the relevance of developing GPs’ skills through ”Motivational interviewing” and the importance of acknowledging the difficulties of changing professional behaviour 98. This study has focused on the first level towards implementing ”Motivational interviewing”, viz. to change the way GPs are integrating ”Motivational interviewing” into their daily work. Further research into the precise use of ”Motivational interviewing” by GPs is required in order to identify which methods are most effective and why. Another aspect to be addressed is whether and how the use of ”Motivational interviewing” affects the patient’s attitudes toward changing behaviour, e.g. life style and adherence. Finally future research should explore the effect on patient risk profile. The ADDITION-study 13is an ongoing 32 study which aims to gather all these issues into a RCT to evaluate whether a course in ”Motivational interviewing” change the professional behaviour of GPs, whether patients change behaviour and if this improve the risk profile. Conclusion A ”Motivational interviewing” course seems to influence GPs’ professional behaviour. GPs find that the course provide them with skills that afford them greater confidence in using ”Motivational interviewing” for patient treatment. GPs found that ”Motivational interviewing” was more effective than “traditional advice giving” and that it improved the patient-doctor relationship. Furthermore, the experienced GPs used more complex parts of ”Motivational interviewing” and found that the methods was not more time-consuming than “traditional advice giving”. Whether ”Motivational interviewing” results in a better prognosis for patients remains to be proved. 33 34 Chapter 4 Effect of “Motivational interviewing” on beliefs and behaviour among patients with Type 2 diabetes detected by screening. ADDITION Denmark. Rubak S, Sandbaek A, Lauritzen T, Borch-Johnsen K, Christensen B. 35 Abstract Background: ”Motivational interviewing” has been shown to be broadly applicable in the management of behavioural problems and diseases associated with unhealthy lifestyle. Only few studies have evaluated the effect of ”Motivational interviewing” on the treatment of Type 2 diabetes and none have explored the effect of “Motivational interviewing” on target-driven intensive treatment of this disease. Aim: To evaluate whether “Motivational interviewing” in general practice improves screened Type 2 diabetes patients’ beliefs about Type 2 diabetes and its consequences, and whether it changes their behaviour. Study design: Two groups of GPs were randomised to training in ”Motivational interviewing” or not. Both groups received training in target-driven intensive treatment of Type 2 diabetics. Methods: The intervention consisted of a 1½-day residential course in ”Motivational interviewing” with ½-day follow-ups twice during the first year. Data from patients was obtained using previously validated questionnaires. Results: The study obtained 87% response rate. Patients in the intervention group were statistically significantly more autonomous and motivated in their inclination to change behaviour compared to patients from the control group after one year. Patients in intervention group were also statistically significantly more conscious of the importance of controlling their diabetes and had a significantly better understanding of the possibility of preventing complications. However the significant differences between the groups were small. Discussion/Conclusion: Questionnaires one year showed that “Motivational interviewing” had improved on patient beliefs of Type 2 diabetes treatment and their contemplation and readiness to behaviour change. No change was seen in self-reported lifestyle behaviour. 36 Introduction Type 2 diabetes attracts growing attention because of rising prevalence, its accompanying disablement due complications and the reduced life expectancy associated with this disease. At the root of this problem lies inexpedient lifestyle behaviour, failure to adhere to intensive treatment and prescribed medication 99-102. Most Type 2 patients are being treated in primary care, but the majority of studies of intensive treatment of patients with Type 2 diabetes have been performed in hospital settings and without the use of “Motivational interviewing” 99-102. However, there is a growing interest in methods like “Motivational interviewing”, one of the rather well-known, scientifically tested method of client counselling developed by Miller and Rollnick 2. It is viewed as a useful intervention strategy for changing behaviour and it may be instrumental in improving the prognosis of the disease. “Motivational interviewing” has been used as an intervention strategy in several contexts, e.g. alcohol abuse, drug addiction, smoking cessation, weight-loss, adherence to treatment and follow-up, increase of physical activity, asthma treatment and diabetes treatment 5. A previous study showed a course in “Motivational interviewing” can influence GPs professional behaviour towards using the method in general practice 103. This study, performed in general practice, aims to evaluate whether “Motivational interviewing” of Type 2 diabetes patients detected by screening can improve their self-reported 1) contemplation and readiness to change behaviour, 2) actual change in patient behaviour, and 3) beliefs regarding Type 2 diabetes. 37 Methods Study group This study is a sub-study of the ADDITION study 13, which is a multi-centre randomised controlled trial of a target-driven approach to intensive treatment of patients with Type 2 diabetes detected by screening. All practices registered at the County Health Insurance Registry in Aarhus County were 1. January 2001 invited to meetings about participation in the ADDITION-study. In Copenhagen County only practices located in the north and eastern part (7 municipalities) were invited, because screening for diabetes had already taken place in the remaining municipalities in the county in connection with the Inter99 study. In agreement with the County Health Insurance only 60 GPs were to be included per county at study onset, and primarily practices with more than one GP were included. No exclusion criteria for the GPs were applied and included GPs were randomised at practice level into a group giving standard care or an intervention group educated to intensive treatment including lifestyle intervention and poly-pharmacy aiming for rigorous values of blood glucose, blood pressure and lipids in addition to anticoagulation treatment. This study included practices/GPs from the intervention group of the ADDITION study. These practices/GPs were sub-randomised into an intervention group (I-group) comprising GPs receiving a course with training in ”Motivational interviewing” and a control group (C-group) comprising GPs receiving no formal training in ”Motivational interviewing”. Randomisation was stratified by county (Copenhagen and Aarhus) and size of practices. GPs received training free of charge. The inclusion of GPs and patients is shown in the flowchart, Figure 1. Patients were included in the study by the following inclusion-/exclusion criteria: All newly diagnosed Type 2 diabetes patients detected by screening aged 40-69 years were eligible unless they were found to have contraindications or intolerance to study medication; a history of alcoholism, drug abuse, psychosis or other emotional problems that were likely to invalidate informed consent or adherence to treatment; malignant disease with a poor prognosis; or were pregnant or lactating. Patients previously diagnosed with diabetes or treated with blood glucose lowering agents were excluded. 38 Figure 1.

The teacher is the first author of ”Motivational interviewing ”, a manual from the Danish Scientific Society of General Practitioners (2000) 89 which together with “Motivational interviewing, preparing people to change addictive behaviour” (1991) 2 constituted the theoretical part of the course curriculum. Each course included 6-8 GP participants. Each session started with a short introduction to the methods of “Motivational Interviewing” followed by group discussions and training the methods involving a high level of participation in workshops and role-plays. The principal rules of “Motivational Interviewing” in relation to the patient-doctor relationship 2 were trained as was the use of the specific skills e.g. empowerment 90, use of the ambivalence 2, the decisional balance schedule 2, visual analogue scale 2 and stage of change 91 and reflective listening 2. The courses for the GPs in the I-group consisted of a 1½-day training sessions with a ½-day followup twice during the first year. None of the GPs in I- and C-group had previously participated in a course in ”Motivational interviewing”. All GPs in the I- and the C-group had participated in the same training courses in intensive treatment of Type 2 diabetes patients. This training course lasted half a day and follow up was performed as afternoon meetings twice every year. During these diabetes training sessions, it was stressed that GPs should act as counsellors for the patients, allowing treatment decisions to be based on a mutual understanding between the patient and the GP. Measurements The intervention phase began 1. May 2001 and included the 1-year follow-up data. The questionnaire used for assessment consisted of a collection of previously validated questionnaires used in primary care and on Type 2 diabetes patients: - Health Care Climates Questionnaire (HCCQ) 104-108. It assesses the patient’s perceptions of patient-doctor relationship and the the degree to which counselling are autonomous supportive versus controlling. In this study the short 6-item HCCQ was used. It includes 7 items using a Likert scale with categories from “not at all true” to “very true”. - Treatment Self-Regulation Questionnaire (TSRQ) 105;108-110. It assesses the degree to which behaviour tend to be self-determined. The main scale includes three subscales: the “autonomous” regulatory style; the “controlled regulatory” style; and “amotivation” style. The “autonomous style” represents the most self-determined form of motivation and has consistently been associated with behaviour change and positive health care outcomes 105. TSRQ is a questionnaire including 21 items. It involves a 7-item Likert scale with categories from “not at all true” to “very true”. - Diabetes Illness Representation Questionnaire (DIRQ), which comprises two questionnaires, the Illness Perception Questionnaire (IPQ) and the Personal Models of Diabetes Interview Questionnaire (PMDIQ) 92;93;111. The DIRQ questionnaire assesses Type 2 diabetes patient’s beliefs and understanding of Type 2 diabetes and involves 5 subscales: Identity (symptoms associated with the illness); cause (the cause of illness and the factors responsible for illness onset); timeline (patient’s perception of duration of the illness); threat, impact i.e. consequences (patient’s expected outcome of the illness); and prevent/control/treatment/effectiveness (patient’s beliefs about the extent to which 40 the illness is amenable to cure, in which way prevention is possible and how good recommended treatments are at controlling the illness). In this study we only used 4 of the subscales, excluding “identity” because we obtained this by the GPs’ reports. All questions involve a 5-item Likert scales with categories from “no importance” to “extremely important”. The DIRQ included 30 items. - Summary of Diabetes Self-Care Activities (SDSCA).95;112-116. It assesses to which extent Type 2 diabetes patients perceive advice on various self-care activities related to Type 2 diabetes. The questionnaire focuses on which advice from the counsellor has been perceived by the patient in relation to: general diet and specific diet ; exercise; testing and controlling; adherence to prescribed medication; foot care; and smoking. The answering categories were either listed on a dichotomous (yes/no) or a continuous scale (viz. “On how many of the last 7 days did you ...?”). The SDSCA included 13 items. - 13 self-constructed and pilot tested questions on self-care activities in relation to smoking, alcohol and exercise. Answering categories were dichotomised or presented on a continuous scale. Sum-scores were calculated for the questionnaires HCCQ, TSRQ and DIRQ. The sum-scores for questions were calculated to obtain an overall picture of each patient’s views on different subjects (Table 1 and 5). Questionnaire responses for each subject were first reversed in order to unify the direction of the response to each question. Then the responses were added and divided by the number of responses to generating a mean response. The method of sum-scoring questions has been used and validated in different settings 92;93;95;96;108-111;117. All the questionnaires were translated by the conventional principal rules of forward-backward translation. The authors translated from English into Danish and a British subject residing in England speaking Danish translated backward again in order to ensure mutual agreement of the translation. After the translation, the final Danish questionnaire was pilot-tested and validated on a group of 5 GPs and a group of their Type 2 diabetes patients. Questionnaires to all patients in both groups of GPs were mailed at baseline and 6 and 12 month after inclusion. One reminder was sent in case of no response within four weeks. The questionnaires were designed in and read by the computer program Teleform 118, which ensures reliable and valid data 119. Statistical method Statistical analysis of data was conducted in SPSS (version 11.0). All single variables containing data from a Likert scale were analyzed by Non-Parametric Mann Whitney test. All sum-score variables followed a normal distribution and consequently a T-test was therefore performed. Results are either given as median and quartiles, simple percentages or as mean and 95% confidence interval (CI). A statistical significance level of 0.05 (two tailed) has been used. The clustering of GPs was adjusted for by using a mixed regression model assuming random (normal) variation between and within GPs. 41 Results A flowchart for participating practices (GPs) and patients is shown in Figure 1. In all, 48 practices (65 GPs) were included. Twenty-seven practices (36 GPs) were randomised into the I-group and 21 practices (29 GPs) into the C-group. Two practices (6 GPs) and 2 patients dropped out after randomisation. All GPs in the I-group participated in the training courses, and less than 10% were absent from the ½-day follow-up meetings. The study included 265 Type 2 diabetes patients detected by screening with a one year follow-up; 128 in the C-group and 137 in the I-group. The response rate to the patient questionnaire was 87% in the I-group and 90% in the C-group. Among the 265 patients, 59% were males, average age of 62 years, 33% of patients with familiar history of diabetes, with no significant differences between the study groups. The GPs had an average age of 53 years, were male in 2 out of 3, and had an average of 1500 patients in their practice with no significant differences between the study groups. The sum-scores for the HCCQ- and TSRQ-questionnaire are presented in Table 1. Table 1.

With regard to treatment and self-regulation, both groups wanted “controlling counselling” (TSRQ-control), even when they stayed “autonomous” in their behaviour decisions (TSRQ-autonomy). Patients from the I-group were statistically significantly more autonomous in their choice of action towards behavioural changes than patients from C-group after one year. Patients from the I-group were statistically significantly more motivated for changing behaviour (less “TSRQ-amotivation”) than patients in the C-group after one year, but not after 6 month. 42 Table 2 features self-reported advice from GPs regarding diet, exercise and self-control of diabetes after one year. Patients in the I-group reported having received statistically significantly more specific advice from their GP regarding diet, exercise and self-control of diabetes than patients in the C-group after one year. The differences in perceived advice from the GPs became more statistical significant after 12 month compared to 6 months of study period. Table 2.

Table 4 shows changes in patients’ beliefs regarding their diabetes. Patients in the C- and I-group showed no significant differences in terms of their opinion about the threat and the impact diabetes imposed on their lives and on the time aspects of their disease. Patients in both groups reported controlling their diabetes and paying attention to preventing factors as important. Patients in the Igroup were statistically significantly more aware of the importance of controlling their diabetes for specific factors than patients in the C-group and they also had a statistically significantly better understanding of the probability of how different factors would prevent complication.

Furthermore, patients in the I-group were more knowledgeable and had a better understanding of which factors would help prevent complications and ensure relevant disease control. The autonomous style represents the most self-determined form of motivation and has consistently been associated with behavioural change and positive health care outcomes 105;108-110. A RCT-study showed that changes in perceptions of autonomy predicted change in glycemic control 108. These findings suggest that “Motivational interviewing” have moved more patients in the I-group than in the C-group into the contemplation phase and that they increased their readiness to change behaviour. Strength and limitations We cluster randomised at practice level in order to avoid contamination between the interventionand control group 120. The cluster design does affect the statistical analysis, because in this design the patients are not independent individuals statistically and the statistical analysis has to be performed using the number of cluster units, thus reducing the total number in the comparing groups. 120-122. Cluster randomisation with a small number of units is not likely to show similar distributions of baseline characteristics among groups 123. However, we included 48 practices in 2 counties, which secured similar distributions in each treatment group. Furthermore, we performed stratified randomisation of GPs on size of practice and on county. We hence anticipate a high internal validity, a low degree of selection bias and a random allocation of unpredictable, immeasurable confounders. The study showed that the GPs in the different groups included an equal number of Type 2 diabetes patients, which supports the conclusion that selection bias was limited. The number of GPs and patients’ (all in C-group) dropped out of the study after randomisation is not expected to bias the results in consideration of the total number of GPs and patients included in this study. The study did not include blinding and behavioural changes may therefore be influenced by the Hawthorne effect 124. However in this PhD project both groups of patients were treated with intensive treatment and only one group was further exposed to “Motivational interviewing”. In this way attention to the treatment of Type 2 diabetes including lifestyle changes would increase in both groups and a potential Hawthorne effect would hence exist in both groups. If the patients’ consciousness about changing lifestyle behaviour was raised because of the Hawthorne effect, this would tend to reduce the effect of “Motivational interviewing”. The validity of the study is strengthened by a high response rate to the questionnaire and the use of sum-scoring, a validated method increasing the power of the statistical analysis. The measuring methods used to observe patient behaviour change was mainly based on validated questionnaires which increase the reliability of our results. The study may suffer from a limitation because training in “Motivational interviewing” was only performed by one person. This makes outcome highly dependent on this person’s teaching methods and capacity to train the GPs 103. This person was, however, highly experienced in the methods of “Motivational interviewing” and in teaching. We evaluated the course and found GPs in the I-group adhered more to the methods of “Motivational interviewing” than GPs in the C-group 103. 45 In order to ascertain an effect of behavioural intervention, it is necessary to adopt a triple approach assessing 1) professional behavioural change to “Motivational interviewing” on the part of the counsellor, 2) patient behavioural change and/or attitudes to entering contemplation phase of behavioural change, and finally 3) effect on patient outcome measures e.g. risk profile 103. This paper presents the results of the second stage. The presentation of the effect measures of patient risk profile of this study awaits publication. Detailed findings It was unexpected to find that GPs in I-group gave patients more advice on diet, exercise and selfcontrol of diabetes than GPs in the C-group. In a similar trial investigating the effect of patientcentred care on lifestyle, Kinmonth et al reported that patients became more satisfied by their GP’s counselling style, however with no effect on perceived advice or the risk profile 125. The authors suggested that that GPs became too focused on the consultation process at the expense of disease management 125. Our interpretation of the results in this paper is that GPs in the I-group used “Motivational interviewing” to increase the patients’ awareness of the need for behavioural changes in lifestyle and adherence to diabetes treatment, which led the patients to believe that they had received more advice and thus integrated the behavioural change to a higher degree than patients in the C-group. However, whether this study shows effect on the patients risk profile remains to be seen. GPs in both groups managed to educate the patients to the same level of knowledge about the causes of Type 2 diabetes, its time-aspects and the consequences of complications. However, in the I-group GPs counselling had a significant impact on the patients’ understanding of factors preventing complications and factors controlling the disease compared with the C-group. This improved understanding or higher levels of awareness can also be interpreted as the patients’ acceptance of the disease and their interest in knowing which opportunities they had for preventing complications through lifestyle behavioural changes and adherence to medication. Even though the differences obtained were small, the results do indicate that more patients in the I-group than in the C-group entered contemplation phase and thereby possibly increased their readiness to change behaviour. With regard to the lack of change of alcohol intake behaviour, the results revealed that more than 98% of the patients in both groups were, in fact, within the treatment goals, which left only little room for demonstrating effect of “Motivational interviewing”. The study showed a tendency that more GPs in I-group than C-group asked the patients about smoking status and behaviour (Chapter 4, Table 3, page 44). However, no change was found in smoking behaviour, which may be caused by the GPs not using the opportunity to focus on smoking behaviour or the GPs not motivating for smoking behaviour change. The patients’ statements indicated the latter, thus, that they were not motivated to change smoking behaviour. Whether this was a result of GPs including many subjects (e.g. smoking behaviour, lifestyle behaviour, Type 2 diabetes self-care etc.) in the same counselling encounter, or if it was their use of the “Motivational interviewing”, or the concept of “Motivational interviewing” itself, was difficult to determine for certain. Implications for future research The study measured no effect on behavioural change, e.g. smoking status or alcohol intake, despite changes in patient beliefs, contemplation and readiness to change behaviour. Thus, the measuring methods and the intervention of a study need to be considered. In this study, the method has shown overall effect on the contemplation of behavioural change. It has previously been shown that a ”Motivational interviewing” course seemed to influence GPs’ professional behaviour and GPs 46 reported that they used ”Motivational interviewing” in their daily practice 103. This supports that ”Motivational interviewing” does have effect, however long-term evaluation is needed in order to capture effect at both GP-level (changing professional behaviour) and patient level (contemplation towards change and occurred change). Conclusion This study reports a statistically significant effect of ”Motivational interviewing” on patients beliefs regarding Type 2 diabetes and on their contemplation and readiness to change behaviour. However, both groups obtained effects, and even though the effect of ”Motivational interviewing” was statistically significant, it remained a small additional effect. Thus, the importance of this finding in clinical setting is uncertain. The study showed no significant change in actual change of smoking and alcohol intake behaviour. Whether better results of ”Motivational interviewing” can be obtained over a longer period of time has to be investigated. 47 48 Chapter 5 No effect of “Motivational interview” on risk profile in patients with Type 2 diabetes detected by screening. A one year follow-up of a RCT. ADDITION Denmark. Rubak S, Sandbaek A, Lauritzen T, Borch-Johnsen K, Christensen B. 49 Abstract Background: ”Motivational interviewing” has been shown to be broadly applicable in the management of behavioural problems and diseases associated with unhealthy lifestyle. Only few studies have evaluated the effect of ”Motivational interviewing” on the treatment of Type 2 diabetes and none have explored the effect of “Motivational interviewing” on target-driven intensive treatment of this disease. Aim: To investigate whether an improved risk profile can be achieved following implementation of “Motivational interviewing” in general practice. Study design: Two groups of GPs were randomised to training in ”Motivational interviewing” or not. Both groups received training in target-driven intensive treatment of patients with Type 2 diabetes. Methods: The intervention consisted of a 1½-day residential course in ”Motivational interviewing” with ½-day follow-ups twice during the first year. Blood samples, case record forms, national registry files and validated questionnaires from patients were obtained. Results: The study showed statistically significant changes in terms of improved metabolic status and adherence during the intervention period within both randomisation groups. However, there was no significant difference between the randomisation groups after one year. Conclusion: Based on a one year follow-up, we found no effect of “Motivational interview” on the risk profile in patients with Type 2 diabetes detected by screening. 50 Introduction A large proportion of patients with Type 2 diabetes are treated in primary care. Despite this, most previous studies on intensive multi-factorial treatment have been conducted in hospital setting 99;102. A major problem in these studies has been poor patient adherence to healthy life style and poor adherence to medication 99;102. New approaches to achieve behavioural changes are therefore required to be introduced. “Motivational interviewing” is one of the rather well-documented, scientifically tested methods of client counselling developed by Miller and Rollnick and it is viewed as a useful intervention strategy for changing behaviour and improving disease management 2. “Motivational interviewing” has been used in very few studies of Type 2 diabetes and the results have been varying 5;14;43;103. No investigations have evaluated its effect in relation to target-driven intensive treatment of patients with Type 2 diabetes detected by screening in primary care. The aim of this study is to show whether a course in “Motivational interviewing” for general practitioners (GPs) improves patient adherence to intensive treatment based on an evaluation of the risk profile of patients with Type 2 diabetes detected by screening. Method Study group This study is a sub-study of the ADDITION study 13, which is a multi-centre randomised controlled trial of a target-driven approach to intensive treatment of patients with Type 2 diabetes detected by screening. All practices registered at the County Health Insurance Registry in Aarhus County were 1. January 2001 invited to meetings about participation in the ADDITION-study. In Copenhagen County only practices located in the north and eastern part (7 municipalities) were invited, because screening for diabetes had already taken place in the remaining municipalities in the county in connection with the Inter99 study. In agreement with the County Health Insurance only 60 GPs were to be included per county at study onset, and primarily practices with more than one GP were included. No exclusion criteria for the GPs were applied and included GPs were randomised at practice level into a group giving standard care or an intervention group educated to intensive treatment including lifestyle intervention and poly-pharmacy aiming for rigorous values of blood glucose, blood pressure and lipids in addition to anticoagulation treatment. This study included practices/GPs from the intervention group of the ADDITION study. These practices/GPs were subrandomised into an intervention group (I-group) comprising GPs receiving a course with training in ”Motivational interviewing” and a control group (C-group) comprising GPs receiving no formal training in ”Motivational interviewing”. Randomisation was stratified by county (Copenhagen and Aarhus) and size of practices. GPs received training free of charge. The inclusion of GPs and patients is shown in the flowchart, Figure 1. Patients were included in the study by the following inclusion-/exclusion criteria: All newly diagnosed Type 2 diabetes patients detected by screening aged 40-69 years were eligible unless they were found to have contraindications or intolerance to study medication; a history of alcoholism, drug abuse, psychosis or other emotional problems that were likely to invalidate informed consent or adherence to treatment; malignant disease with a poor prognosis; or were pregnant or lactating. Patients previously diagnosed with diabetes or treated with blood glucose lowering agents were excluded. Diagnostic criteria for Type 2 diabetes is defined as fasting capillary whole blood glucose above 6,1 mM or oral glucose tolerance 2-hour test above 11,1 mM 13. 51 Figure 1.

The teacher is the first author of ”Motivational interviewing ”, a manual from the Danish Scientific Society of General Practitioners (2000) 89 which together with “Motivational interviewing, preparing people to change addictive behaviour” (1991) 2 constituted the theoretical part of the course curriculum. Each course included 6-8 GP participants. Each session started with a short introduction to the methods of “Motivational Interviewing” followed by group discussions and training the methods involving a high level of participation in workshops and role-plays. The principal rules of “Motivational Interviewing” in relation to the patient-doctor relationship 2 were trained as was the use of the specific skills e.g. empowerment 90, use of the ambivalence 2, the decisional balance schedule 2, visual analogue scale 2 and stage of change 91 and reflective listening 2. The courses for the GPs in the I-group consisted of a 1½-day training sessions with a ½-day followup twice during the first year. None of the GPs in I- and C-group had previously participated in a course in ”Motivational interviewing”. All GPs in the I- and the C-group had participated in the same training courses in intensive treatment of Type 2 diabetes patients. This training course lasted half a day and follow up was performed as afternoon meetings twice every year. During these diabetes training sessions, it was stressed that GPs should act as counsellors for the patients, allowing treatment decisions to be based on a mutual understanding between the patient and the GP. In Denmark, GPs’ consultation encounters average 15 min. and the County Health Insurance has agreed to one longer prophylactic encounter of 45 min. per patient. In this study the County Health Insurance agreed to allow the GPs in the I- and C-group to undertake three consultations of 45 min. per patient, in which the I-group could use “Motivational interviewing”. Measurements The choice of effect parameters was based on the recommendations from evidence-based guidelines for treatment of Type 2 diabetes. In these guidelines treatment goals are controlled by measuring HbA1c, lipid-profile, blood pressure and body mass index. Furthermore the study aimed at reporting changes in adherence, which required other measures e.g. health care services, selfreported changes from GPs and patients. The intervention phase began 1. May 2001 and included the 1-year follow-up data. The study was based upon the following types of data obtained from all patients: Risk profile The use of blood sample data is addressed in Chapter 5. They include HbA1c, total serum cholesterol, serum LDL, serum HDL and serum triglycerides. Baseline blood samples were analysed as follows: HbA1c was analysed using a Tosoh blood sample analyzer on venous whole blood drawn and stored in EDTA aliquots. HbA1c reference interval is 4,1% to 6,1%. Serum cholesterol, serum HDL-cholesterol and serum triglycerides were analysed using a Hitachi 917 System or an Abbott Aeroset analyzer with an enzymatic colorimetric test as the test principle. LDL-cholesterol was calculated using Fridewald’s formula. Reference interval for serum cholesterol is below 6,0mM, for serum HDL above 0,9mM, for serum triglycerides below 2,5mM and for serum LDL below 4,5mM. All blood samples after baseline were analysed on several laboratories in the two counties, all subject to the Danish quality assurance for laboratories. Body mass index (BMI) and systolic- and diastolic blood pressure (measured sitting at rest at the GP) were obtained from case record forms reported by the GPs. 53 Health care services Prescribed medication was reported by the GPs on case record forms. The number of prescriptions cashed in at the pharmacy by the patient was drawn from the National Health Service Registry. The number of encounters and blood samples was obtained from register data files from the National Health Service Registry. Self-reported data Data on smoking and exercise in leisure time and at work was obtained from patient questionnaires. - The questions on physical activity had previously been validated in the “International Physical Activity Questionnaire (IPAQ)” 126. - The questions on smoking had previously been validated in the “Summary of Diabetes Self-Care Activities” (SDSCA) questionnaire 95;112;116. Answering categories for the questions were dichotomised (yes/no) or presented on continuous scales (“On how many of the last 7 days did you ...?”). The questionnaires were designed in and read by the computer program Teleform 118, which ensured reliable and valid data 119. Statistical method Data was blinded by the use of serial numbers in order to prevent observer bias. Statistical analysis of data was conducted in SPSS (version 11.0). Results are either given as median and quartiles, simple percentages or as mean and 95% confidence interval (CI). Paired T test was used to compare changes from 0 to 12 month. A statistical significance level of 0.05 (two tailed) was used. The clustering within GP's was adjusted for by using a mixed regression model assuming random (normal) variation between and within GPs. Results A flowchart for participating practices (GPs) and patients can be seen in Figure 1. In all, 48 practices (65 GPs) were included. The 27 practices (36 GPs) were randomised into the I-group and 21 practices (29 GPs) into the C-group. Two practices (6 GPs) and 2 patients dropped out after randomisation. All GPs in the I-group participated in the educational and training courses, and less than 10% were absent from the ½-day follow-up meetings. The study included 265 Type 2 diabetes patients with a 1-year follow-up; 128 in the C-group and 137 in the I-group. The response rate to the patient questionnaire was 87% in the I-group and 90% in the C-group. According to the case record forms, 74% patients in the I-group and 79% in the C-group had visited their GP one year after their inclusion in the study (Table 1). The GPs had an average age of 53 years, were male in 2 out of 3, and had an average of 1500 patients in their practice with no significant differences between the study groups. 54 Table 1.

After one year, blood glucose, serum-lipid profile, blood pressure, physical activity, BMI, drug prescriptions reported by GPs, drug prescriptions cashed in at the pharmacy and the number of visits to the GP did not differ between patients being treated by GPs trained in “Motivational interviewing” and those who were treated by GPs who had received no such training. The study showed significant changes in patient outcome with improved metabolic status and treatment adherence after one year within both groups. Strength and limitations The validity of the study is strong by virtue of 1) the attendance of all GPs in courses intended for each group, 2) the absence of less than 10% GPs from the follow-up meetings, 3) a patient response rate to the questionnaire exceeding 87%, 4) acquisition of 74% of the case record forms from GPs in the I-group and 79% from GPs in the C-group, and 5) acquisition of a 100% data rate from the National Health Service Registry. Blood samples during the 1-year follow-up was obtained from 61%-91% of the patients (Table 1). This range may introduce a bias in the interpretation of data at the 61% end of this continuum. Furthermore, data rates obtained on serum lipid profiles in the Igroup were statistically significantly lower compared to the C-group, which may introduce selection bias and tend to decrease the difference between the two groups. The number of GPs and patients’ (all in C-group) dropped out of the study after randomisation is not expected to bias the results in consideration of the total number of GPs and patients included in this study. The study did not include blinding, in which case behavioural changes may be influenced by the Hawthorne effect 124. However, in this PhD project both groups of patients were treated with intensive treatment, and only one group was further exposed to “Motivational interviewing”. In this way attention to the treatment of Type 2 diabetes including lifestyle changes would increase in both groups and a potential Hawthorne effect would hence exist in both groups. If the patients’ consciousness about changing lifestyle behaviour was raised because of the Hawthorne effect, this would tend to reduce the effect of “Motivational interviewing”. We cluster randomised at practice level in order to avoid contamination between intervention- and control group 120. The cluster design does affect the statistical analysis, because in this design the patients are not independent individuals statistically and the statistical analysis has to be performed using the number of cluster units, thus reducing the total number in the comparing groups. 120-122. Cluster randomisation with a small number of units is not likely to show similar distributions of baseline characteristics among groups 123. However, we included 48 practices in 2 counties, which secured similar distributions in each treatment group. Furthermore, we performed stratified randomisation of GPs on size of practice and on county. We hence anticipate a high internal validity, a low degree of selection bias and a random allocation of unpredictable, immeasurable confounders. This study may suffer from a limitation because training in “Motivational interviewing” was only performed by one person. This makes outcome highly dependent on this person’s teaching methods and capacity to train the GPs 103. This person was, however, highly experienced in the methods of 57 “Motivational interviewing” and in teaching. We evaluated the course and found GPs in the I-group adhered more to the methods of “Motivational interviewing” than GPs in the C-group 103. Detailed findings Adherence to prescribed medication was high compared with previous studies despite intensive poly-pharmacological treatment, however, there was no significant differences between the groups 127-129 . This may be the result of the intensive training in treatment of Type 2 diabetes, where it was stressed that GPs should act as counsellors advising the patients how to reduce the risk of late diabetic complications and allowing treatment decisions to be based on mutual understanding between the patient and the GP. This is indicated in a previously published paper in this study on how “Motivational interviewing” influences GPs’ professional behaviour 103. Thus, the effect of “Motivational interviewing” may have been reduced because of GPs in the C-group had a greater awareness into all aspects of Type 2 diabetes treatment, including motivating lifestyle changes. The lacking effect of “Motivational interviewing” may also be ascribed to GPs failure to use all the potential three motivational consultations made available by the study. GPs in the I- and C-group on average used only one prophylactic consultation for each patient. Thus, the possibility of an effect on the risk profile would have been higher if the GPs in I-group had used all three consultations deploying “Motivational interviewing”. The results revealed that a large part of the patients in both groups had values (e.g. HbA1c, lipidprofile, blood pressure or BMI) that were, in fact, within the treatment goals from the beginning of the study. This left only little room for demonstrating an effect of ”Motivational interviewing” due to the narrowness of the intervention field. However, significantly more patients in the C-group than in the I-group achieved the treatment goal of blood pressure reduction, but there was no significant difference in mean blood pressure between the groups. The reason for this may be that the patients in C-group only had marginal increased blood pressure, and subsequently the patients achieved treatment goals with only a small decrease in blood pressure. Thus, a difference between the study groups in patients achieving treatment goals of blood pressure was seen, however, with no significant difference in mean blood pressure between the study groups. Another reason for more patients in C-group than I-group achieving treatment goal for blood pressure may be that the GPs was too focused on the consultation process at the expense of disease management as reported earlier in a study with a similar design investigating patient-centred care targeting lifestyle changes 125 . The issue of focusing on behaviour change e.g. diet counselling, thus leading to less focus on other medical treatment e.g. medication is addressed in a newly published paper in the Lancet 130. Implications for future research and practice The measuring methods used to observe patients’ behavioural changes included both self-reported measures, e.g. validated questionnaires and effect measures on patient outcome, e.g. HbA1c. This ensured valid results regarding the effect of ”Motivational interviewing”. We have previously outlined that in order to obtain an effect of behavioural intervention, it is important to measure this effect at several levels, viz. the level of 1) professional behavioural change, 2) patient behavioural change and/or attitudes to entering the contemplation phase of behavioural change, and 3) effect measures, e.g. changes in risk profile 103. Previous studies using ”Motivational interviewing” in general practice have proven an effect of this approach 21;24;36;38;43;60;64. However, only few studies have focused on how to implement ”Motivational interviewing” in the daily clinical work in general practice in such a way that it is ascertained that the method is used after study closure 87;88. They concluded that it despite barriers 58 was possible to implement the use “Motivational interviewing” in general practice 87;88. This study showed that GPs found that implementation of “Motivational interviewing” was not timeconsuming and de facto used the same or fewer consultation encounters than GPs resorting to “traditional advice giving” 103. Thus, the results decrease the concerns over the time-consuming aspect of this technique and its concomitant expenses in primary health care services. The study period lasted one year, a period during which the GPs received training and had to adapt to the methods of “Motivational interviewing” and to use the technique with a number of patients, make these patients change lifestyle to the effect that changes could be measured on their risk profile. This PhD-study has previously shown that 1) a ”Motivational interviewing” course seemed to influence GPs’ professional behaviour, 2) GPs reported that they used ”Motivational interviewing” in their daily practice, and 3) that patients’ changed contemplation of behaviour. The findings of this study support the hypothesis that the non-significant effect of ”Motivational interviewing” on risk profile may be a result of the study’s attempt to accomplish too much over too short a period. Conclusion Based on a 1-year follow-up, we found no effect of the motivational interview on the risk profile in patients with Type 2 diabetes detected by screening. Two recent meta-analyses concluded that psychological therapies improve long-term glycaemic control, and “Motivational interviewing”, as one of these methods, had an effect on lifestyle factors like food intake, smoking, alcohol consumption and medication adherence 5;131. These meta-analyses side with the results of the present study on GPs’ professional behaviour and patient behaviour 103 in supporting the need for long-term evaluation of the effect of ”Motivational interviewing” on the risk profile. 59 60 Chapter 6 General discussion of methods 61 Introduction This section offers a comprehensive discussion of the methods used in this study, adding perspective to the research questions posed. The issues raised are: 1. Setting of the study 2. Design (cluster randomisation, bias, blinding, study evaluation) 3. Intervention (monitoring of intervention, adherence to the method of “Motivational interviewing”, changing and sustaining long-term change of professional behaviour) 4. Measuring methods (questionnaires to GPs, questionnaires to patients, case record forms, blood sample data, registry data) 5. Statistical methods 6. Generalisation of outcome Setting of the study The clinical setting of this study was Danish general practice in the counties of Copenhagen and Aarhus. The scientific setting of the study was conducted from the Department of General Practice, University of Aarhus and the Steno Diabetes Centre, Gentofte. The ADDITION-study aimed at investigating the effect of early detection of Type 2 diabetes by screening and multi-factorial intensive treatment, including “Motivational interviewing”. However, the ADDITION-study did not intend specifically to evaluate if and how the “Motivational interviewing” was used and implemented in patient-doctor relationship, and if it yielded effect on treatment goals. This PhD study focuses on the effect of “Motivational interviewing” on GPs professional behaviour, patients lifestyle behaviour and effect on patient risk profile. The study was conducted in general practice, because treatment and follow-up of Type 2 diabetes is situated well in general practice. Furthermore, general practice was preferred to hospital setting because of the GPs’ profound knowledge with each patient, and thereby the possibility of close follow-up by the GPs. All practices registered at the County Health Insurance Registry in Aarhus County were 1. January 2001 invited to meetings about participation in the ADDITION-study. In Copenhagen County only practices located in the north and eastern part (7 municipalities) were invited, because screening for diabetes had already taken place in the remaining municipalities in the county in connection with the Inter99 study. In agreement with the County Health Insurance only 60 GPs were to be included per county at study onset, and primarily practices with more than one GP were included. No exclusion criteria for the GPs were applied and included GPs were cluster-randomised at practice level. The PhD study included furthermore a group of GPs who previously had participated in the course in “Motivational interviewing” (EM-group). This group was contacted externally to the ADDITION-study and was asked to answer the same questionnaire as GPs within the ADDITIONstudy, thus serving as a group of GPs with long-term knowledge of the use of “Motivational interviewing”. The GPs in the EM-group did not participate in the ADDITION-study. Design The research questions of this PhD thesis (Chapter 1, Aim, page 4), were addressed at the level of the GP and the patient, using measuring methods on changing behaviour of GPs and patients and on specific effect, e.g. risk profile, in conformity with previous research advice 132. The study was conducted as a cluster-randomised controlled trial. 62 Cluster randomised controlled trial The CONSORT principal rules of classic RCT presuppose the use of a homogeneous population, blinding and placebo treatment 123;133-135. However, the study design used here involved clusterrandomisation, i.e. it is a pragmatic RCT, which demands special statistical methods to be considered 122;135-137. Statistical analysis is, for example, affected by the reduced number of units for randomisation 120;121;138-141, (Statistical methods, Page 69). Cluster-randomisation with a small number of units is not likely to show similar distributions of baseline characteristics among groups 123 . However, the study included 48 practices in 2 counties, which secured similar distributions in each randomisation group. Furthermore, there was performed stratified randomisation of GPs on size of practice and on county. Practices were chosen as randomisation units to prevent confounding between GPs. Patients were randomised by their practice in order to avoid confounding between the I- and C- group. Bias The study design, RCT, randomly allocates unpredictable, immeasurable confounders and diminishes selection bias. Patients were included by known inclusion/exclusion criteria (Figure 1, Appendix A) and afterward randomised, thus diminishing the risk of selection bias. However, the GP sample may have been biased because the GPs self-entered this study. The GPs volunteering to courses and using a new intervention method may be a more motivated group of GPs and may thus be more interested in adopting and implementing new methods in general practice. Furthermore the GPs attending the course in “Motivational interviewing” may be more focused on including patients to the study in order to apply the methods of “Motivational interviewing”. However, an equal number of Type 2 diabetes patients were included in the I- and C-group, which supports our assumption that selection bias was limited. Patients’ baseline data (age, gender, marital status, cohabit status, profession, educational background, family history of myocardial infarction and of diabetes, smoking status, alcohol intake status, ethnicity, weight, height, waist circumference) did not differ between the randomisation groups. Inclusion rates did not differ between the randomisations groups either. Inclusion bias due to skewed inclusion numbers (inclusion rate in intervention group exceeded inclusion rate in control group) is therefore limited. Two patients and six GPs (all in control group) dropped out of the study after randomisation. In consideration of the total number of GPs and patients included in this study, attrition bias is viewed as insignificant 122. Data rates and response rates are listed in Table 1 (Appendix A). Blood samples during the 1-year follow-up was obtained from 61%-91% of the patients (Table 1). This range may introduce a bias in the interpretation of data at the 61% end of this continuum. Furthermore, data rates obtained on serum lipid profiles in the I-group were statistically significantly lower compared to the C-group, which may introduce selection bias and tend to decrease the difference between the two groups. Blinding The use of an educational programme for intervention in practice prevents blinding. It is, of course, not impossible to stage a placebo educational programme, but its effect would be doubtful as the GPs may easily learn from other GPs about their education, and thereby which education was intervention and which was placebo. Without blinding, behavioural changes may be influenced by the Hawthorne effect 124. A Hawthorne effect is defined as when an intervention group have a tendency to change behaviour because they are targeted special attention in a study, regardless of the specific nature of intervention received 124. However, in this PhD project both groups of patients 63 were given intensive treatment and only one group was subsequently exposed to “Motivational interviewing”. In this way attention to the treatment of Type 2 diabetes including lifestyle changes would increase in both groups and a potential Hawthorne effect would hence exist in both groups. If the patients’ consciousness about changing lifestyle behaviour was raised because of the Hawthorne effect, this would tend to reduce the effect of “Motivational interviewing”. An increased consciousness on behaviour may be indicated by the high level of adherence in both groups compared with previous studies despite intensive poly-pharmacological treatment 127-129;142-144. Blinding of patients was intended. Patients were obligated to give written informed consent to their participation in the study, however, they were not informed about whether their GP was allocated to the I-group or the C-group. It was not checked whether some patients during the study learned about which treatment group their GP was assigned to. It may have induced an increased motivation in the patient to know that your GP is in the I-group and vice versus. Furthermore, the study was to be integrated into daily practice, therefore personal initiatives among both GPs and patients in terms of self-education was not opposed and have not been accounted for. However, no GPs in this study had attended a course in “Motivational interviewing” prior to the study. Study evaluation Assessment of the implementation of an educational programme into routine care in general practice requires consideration of all the levels of implementation. It is necessary to evaluate each level of the process relying on a combination of self-reported measures and effect measures of behaviour changes among both GPs and patients 145-147. In this study an effort has been made to use measuring methods evaluating all the levels. The questionnaire data from the GPs focus on how implementation of a training programme changed the professional behaviour. The questionnaire data from the patients make it possible to view changes in patient beliefs concerning Type 2 diabetes treatment and their contemplation and readiness to change behaviour. Finally the specific effect measures make it possible to conclude whether “Motivational interviewing” had an effect on the patients risk profile. In this field of intervention, RCTs do not practice follow-up periods exceeding one year 145, and this PhD study is also limited in the way that the evaluation rest on data obtained at the 1-year followup. However, as a part of the ADDITION-study, the RCT has planned follow-up period of 5 years to evaluate the long-term effect. Intervention The educational programme of “Motivational interviewing” is shown in Appendix B. Intervention is described in detail in Chapter 3 to 5. Monitoring the intervention The effect of “Motivational interviewing” was measured at three levels, i.e. change at GP level, change at patient level and change in patient risk profile. Assessing the effect at the GP level i.e. change of professional behaviour required evaluation of whether the course provided the GPs with skills that afforded them confidence in using ”Motivational interviewing” for patient treatment, and monitoring of their actual use of the methods in their daily routines. The study aggregated the effect of both processes, and therefore, it cannot be specified precisely how the different techniques were used by the GPs after the course. It might have been possible to obtain information about actual use 64 and adherence to “Motivational interviewing” by viewing video recordings of counselling encounters. This way of evaluation has been used previously in other studies of communication skills, and it seems to be a feasible method. However, it requires detailed practical planning, training of the GPs, considerable resources and acceptance from all participating doctors 148-155. This was not possible within the present study period and the resources were not available to use this approach in 48 practices and for 65 general practitioners in 2 counties. In this study a questionnaire survey was conducted one year and three years after the course. Besides this, the outcome of the training course was evaluated at the next two levels, i.e. changing patient behaviour and viewing actual change in patient risk profile as described in the section of “Measuring methods” below. Adherence to “Motivational interviewing” It was expected that GPs in the group attending the course in “Motivational interviewing” would use the method in the patient treatment. However, they were not forced to use the methods, and the extent to which they actually used the methods or adhered to the concept of “Motivational interviewing” was not monitored. Another factor potentially influencing the use and adherence to “Motivational interviewing” is the GPs’ motivation to participate in the study. In a RCT the GPs cannot decide themselves to which group and level of intervention and education they are allocated. Therefore it is possible that some GPs wanted to use “Motivational interviewing”, but were not randomised to this group, and vice versa. In this way, GPs in the “control group” might have been motivated to do more than just “traditional advice giving” and GPs in “intervention group” might not have adhered to the method. This would also tend to reduce the registered effect of “Motivational interviewing”. “Traditional advice giving” is used as an expression for doctor-centred approach, i.e. the GP define the patients’ problem from a biomedical perspective and does not at all include the patient perspective on the matter, thus giving advice accordingly 12;83. Changing and sustaining long-term change of professional behaviour Changing counsellors’ professional behaviour in the doctor-patient relationship requires a tremendous effort 156. In this process, it is important to know how and where to influence the GPs 157 . Multiple strategies based on different theories have been applied but very few studies have explored the long-term effect of training in interviewing skills and treatment 158-162. In order to obtain professional behaviour change, it is necessary to consider the teaching method carefully 163;164 . GPs changing professional behaviour will often have previous advanced experience, which requires that adult learning principles is applied in their education 165-170. If GPs are to be changed, new methods must be scientific based and relevant to general practice 161;162;171 . In medical education passive learning by means of lectures has proven in-effective in terms of retained participants’ knowledge 172-174. Thus, the permanence and integration of professional behaviour change among GPs hinge crucially on practical training of the new method in a clinically relevant case settings, and on how easily the new method can be adopted and used “the next day” in practice. Furthermore it must be clear for the counsellor, why the alternative professional behaviour is preferable 157. In the treatment of Type 2 diabetes patients in general practice, traditional treatment seems neither successful nor effective in terms of changing patient behaviour. Hence, there seems to be a potential for stimulating change of lifestyle through improved professional conduct. This improvement has to derive from a new strategy and this is an argument to retrieve and introduce new methods such as “Motivational interviewing”. 65 Stott et al performed a study on how GPs would react to adopting a new technology and new methods showing that GPs did, indeed, adopt, accept and use the new methods when they facilitated solutions to problems in the patient-doctor relationship 97. Only few studies have focused on how to implement and integrate ”Motivational interviewing” in the daily clinical work in general practice in such a way that it is ascertained that the method is used after study closure 87;88. They concluded that it despite barriers was possible to implement the use “Motivational interviewing” in general practice 87;88. Measuring methods The ADDITION-study is an on-going study based on primary and secondary endpoints evaluated after 5 years, including complete registry data on all included patients 13. The PhD thesis is based upon the following types of data obtained at the follow up after one year: - Questionnaires to GPs - Questionnaires to patients - Case record forms - Blood sample data - Register data files from the National Health Service Registry General practitioner questionnaire No validated questionnaire was available for evaluating the courses in ”Motivational interviewing” and the GPs’ conception of the methods, adherence to the technique and their actual use of ”Motivational interviewing”. A questionnaire was therefore designed drawing on 1) available theoretical knowledge about ”Motivational interviewing”, 2) the leading author’s knowledge from attending the course and 3) knowledge from the teacher and head of the course. The questionnaire was designed in the computer programme Teleform 118. The questionnaire was self-administered and the processing of the questionnaire data was performed using Teleform. The questionnaire was blinded by the use of serial numbers in order to prevent observer bias. The “Teleform method” has been validated by a previous study comparing the use of Teleform and manual data entry, which found that the Teleform method was the more reliable and that it ensured valid data 119. Data were afterward automatically transformed into the Statistical Programme for Social Science (SPSS) version (11.0) for windows 175 and was once more checked for potential errors. If an error was discovered, the original questionnaire was checked for correct answering and change was made in the database. The questionnaire content, construction and pilot testing are addressed in Chapter 3 and the questionnaire is shown in Appendix C. The questionnaire was relevant and well-constructed, because it was understood by all the GPs and produced a 100% response rate. The design of questionnaire and pilot testing ensured feasibility and high validity. Patient questionnaire The patient questionnaire is addressed in the Chapters 4 to 5, and the questionnaire is shown in Appendix C. The questionnaire used for assessment consisted of a collection of previously validated questionnaires used in primary care and for Type 2 diabetes patients. These questionnaires were selected in order to measure the following aspects: 66 - Counselling and patient-doctor relationship Health Care Climates Questionnaire (HCCQ) 104-108;176;177 was used to assess patients’ perceptions of the GP’s counselling style. This questionnaire has previously shown to be effective in disclosing the counselling style in many treatment areas 104-108;176;177. - Contemplation of behaviour change Treatment Self-Regulation Questionnaire (TSRQ) 105;108-110;117;176-178 was used to assess the degree to which behaviour tends to be self-determined. It involves three subscales to the main scale: the “autonomous” regulatory style; the “controlled regulatory” style; and “amotivation” (which refers to being unmotivated). The autonomous style represents the most self-determined form of motivation and has consistently been associated with behaviour change and positive health care outcomes. These subscales correspond to motivational concepts of selfdetermination theory proposed by William GC and Deci EL 104;106, which are partly based on concepts of “Motivational interviewing”, Miller and Rollnick 1. - Understanding of Type 2 diabetes and its implications on life Diabetes Illness Representation Questionnaire (DIRQ), which comprises 2 questionnaires: a. Illness Perception Questionnaire (IPQ) 92;93;111;179-181 b. Personal Models of Diabetes Interview Questionnaire (PMDIQ) 92;93;111;180;181 This questionnaire assesses whether “Motivational interviewing” acts to mediate the relationship between illness representations and emotional well-being in patients with Type 2 diabetes. It assesses patients’ beliefs and understanding of Type 2 diabetes. It involves 5 subscales to the main scale: Identity (symptoms associated with the illness) cause (the cause of illness and beliefs about the factors responsible for the onset of the illness); timeline (the patient’s perception of duration of the illness i.e. acute, cyclical or chronic); consequences (the patient’s expected outcome of the illness in terms of its likely physical, psychological, social and economic implications, which include impact on day-to-day life and in the long term); and control/treatment/effectiveness (the patient’s beliefs about the extent to which the illness is amenable to cure or how good recommended treatments are at controlling the illness). This study only used four of the subscales: cause, timeline, consequences and control/treatment/effectiveness. “Identity” was excluded in order to limit the number of questions in the questionnaire and because all symptoms and objective findings were reported by the GPs on the case record forms. - Advice received on control and self care, and adherence to treatment and self care Summary of Diabetes Self-Care Activities (SDSCA). This questionnaire assesses to which extent Type 2 diabetes patients perceived advice on various self-care activities relevant to Type 2 diabetes. It is a brief questionnaire previously validated in many studies and used to measure diabetes self-management 94;95;112-116;182-184. The questionnaire focuses on which advice from the counsellor has been perceived by the patient in relation to: general diet and specific diet; exercise; testing and controlling by blood-glucose measurement and urine-glucose measurement; medication (which type of medication has been prescribed by the doctor and to which extent has the patient adhered to the prescription); foot care (self-rated self-care activity on patient foot care); and smoking (status of smoking habits). The use of previously validated questionnaires combined with the pilot testing ensured feasibility and high validity. The final questionnaire also enabled comparison with previous research. 67 Case record forms The use of case record forms reported by GPs is addressed in Chapter 5, and the case record forms are shown in Appendix D. Processing of the case record forms was performed by Teleform and analysis of case record form data by SPSS according to the description in “GP questionnaire section” above (page 66). The case record forms at baseline and at 3, 6, 9, and 12 months were used in order to capture potential effects at different points in time. However, no statistically significant differences were measured with 3 month intervals, and the results are therefore presented as baseline, 6- and 12-month data. The data response rate (Table 1, Appendix A) was found to be representative and valid. Blood sample data The use of blood sample data is addressed in Chapter 5. They include HbA1c, total serum cholesterol, serum LDL, serum HDL and serum triglycerides. Baseline blood samples were analysed as follows: HbA1c was analysed using a Tosoh blood sample analyser on venous whole blood drawn and stored in EDTA aliquots. Serum cholesterol, serum HDL-cholesterol and serum triglycerides were analysed using a Hitachi 917 System or an Abbott Aeroset analyser with an enzymatic colorimetric test as the test principle. LDL-cholesterol was calculated using Fridewald’s formula. All blood samples after baseline were analysed on several laboratories in the two counties, all subject to the Danish quality assurance for laboratories. The blood sample data were fed into a database from case record forms reported by GPs and from data files obtained from the central laboratories. These data were combined and displayed in one database by a data-manager to ensure accuracy and eliminate observer bias. Data was blinded by the use of serial numbers in order to prevent observer bias and to comply with the stipulations concerning regulation of databases, the Danish Data Protection Agency. Data were afterwards automatically transformed into the Statistical Program for Social Science (SPSS) version (11.0) for Windows 175. Blood sample data were obtained at baseline and after 3, 6, 9 and 12 months in order to capture potential effects at different points in time. However, no statistically significant differences were measured with the 3-month intervals, and the results are therefore presented as baseline, 6- and 12-month data. Blood sample data was obtained in order to measure effect on the patients’ risk profile. National Health Service Registry data The use of register data files obtained from the National Health Service Registry are addressed in Chapter 5. Data extraction was performed by a data-manager and retrieved into database for all included patients. I used various types of data as measuring method which could have created problems during the data processing and analysis stages. However, the support of a data-manager secured proper data-entry into the database and data could be analysed in SPSS. 68 Statistical methods The intervention, “Motivational interviewing”, targeted the GPs and was supposed to be implemented into the daily clinical work in general practice. Practices were randomisation units. Thereby the included patients were cluster-randomised, meaning that they were allocated into clusters receiving different intervention depending on the grouping of their GP. Statistically, the patients were therefore not independent individuals and the statistical analysis was performed at the level of the practice/GPs. Variability between and within the clusters could arise if the sample included a small number of clusters, because of the individuality of GPs and/or their practices. If variability between the clusters was present and ignored, the confidence intervals would become too narrow 120;122;137;139;185;186. However, when a study includes a large number of cluster units, variability is reduced to an insignificant level and balanced comparison is possible. Random (normal) variation between and within the GPs was assumed on basis of the number of practices/GPs randomised in the study. Statistical analysis was adjusted for the clustering within GPs by using a mixed regression model. Before launch of the ADDITION-study and this PhD study, power analysis was performed. At that time the study assumed inclusion of approximately 650 patients in the intervention arm of the RCT in the ADDITION-study. These 650 patients would be cluster-randomised to GPs trained in using “Motivational interviewing” or not. At that time approximately 60 GPs within approximately 40 practices were expected to be cluster-randomised and that an average of 16 Type 2 diabetes patients would be included per practice. In general practice, the intra-cluster correlation coefficient on outcome is approximately 0.03 to 0.05 121;187. However, Kerry et al investigated cholesterol in general practice and concluded that the intra-cluster correlation coefficient was 0.0036 138. In the power analysis, the intra-cluster correlation coefficient was conservatively estimated to be 0.05 on the remaining primary outcome measures. When sample size in power analysis is to be corrected for cluster-sampling, the following equation was used: N=n/(1+((m-1)xICC)) N=Total number (corrected of cluster-sampling) n=Total number (total number before cluster-sampling correction) m=Average cluster size ICC= Intra-cluster Correlation Coefficient This equation was used in order to reach the corrected number (N), which could be used in the power analysis for the outcome measures below: - HbA1c: N=650/(1+((16-1)x0.05)) =371. - Total cholesterol: N=650/(1+((16-1)x0.0036)) =617. - Adherence to prescribed medication: N=650/(1+((16-1)x0.05)) =371. - Smoking cessation: N=430/(1+((16-1)x0.05)) =245. (It was assumed that approximately 2/3 of 650 patients within the intervention arm of the ADDITION-study were smokers, which makes N=430). 69 In the power analysis SPSS Sample Power Two Sample Proportion was used. After correction of cluster-sampling it was concluded at that time, that the study would show effect (95%CI) of “Motivational interviewing, if: - Min. 19% patients reached normal HbA1c (HbA1c below 6,4) - Min. 15% patients achieved a 10% reduction of total cholesterol - Min. 22% patients achieved smoking cessation - Min. 19% patients adhered to prescribed medication (adherence defined as 90% respecting the prescribed medication) The study did achieve the inclusion of 65 GPs from the beginning of the study. However, it did not reach the goals of including 650 patients within the intervention arm of the ADDITION-study. At the data deadline of the PhD study, only 265 Type 2 diabetes patients with a 1-year follow-up had been included. Thereby it was not possible to fulfil the expectations of measured effect of the study. This is supported by using “post” power analysis on the goals, as an example HbA1c: In power analysis 650 patients was used as “N”, which after correction for clustering allowed us by means of power analysis to conclude that “Motivational interviewing” would show effect if a min. of 19% patients reached normal HbA1c (HbA1c below 6.4). If the included number was used, N=265, then the power analysis after correction for clustering concludes that “Motivational interviewing” would show effect if a min. of 28% patients reached normal HbA1c (HbA1c below 6.4). Finally, a large proportion (56%) of the included patients had HbA1c within treatment goal from the onset of the study, which meant that these patients could not show any change due to “Motivational interviewing”. If the number of included Type 2 diabetes patients who actually had an HbA1c level above the treatment target at baseline (44% of all included patients, N=117) was used, (Chapter 5, Table 3, page 56), then the number would decrease further and power analysis would, after correction for clustered sampling, conclude that “Motivational interviewing” would show effect if a min. of 39% patients reached normal HbA1c (HbA1c below 6.4). Thus, a lower number of included Type 2 diabetes patients decreased the probability of achieving positive effect on patient risk profile. Considering the “form” of intervention (“Motivational interviewing”), the 1-year follow-up period, the patient population (newly diagnosed Type 2 diabetes patients detected by screening), the actual number of included patients, and the large proportion of patients within treatment goal from onset of study, it is questionable whether the study goals could have been reached. Retrospectively, the total number of expected patients should have been reduced in the power analysis in order to take into account that a proportion of the patients might have been within the treatment goal from the study onset. However, the size of this proportion of patients was unexpected. Furthermore, the study goals were deemed clinically relevant and realistic at the study onset which was important if the study should reach a conclusion recommending the implementation of “Motivational interviewing” in general practice in Denmark. 70 Potential generalisation of outcome This study had no exclusion criteria for the GPs, which secured external data validity. The study managed to diminish potential selection bias at GP level by including a large number of GPs from which only 6 GPs dropped out (all in the control group) after randomisation (Figure 1, Appendix A). Patient exclusion criteria were limited to patients previously diagnosed with diabetes, which should not influence the potential generalisation of outcome to the general population. This study includes GPs randomised to a training programme in “Motivational interviewing”, which was flexible in relation to the GPs’ daily work and training in the practical use of specific methods was focused and targeted Type 2 diabetes patients. Therefore it may be possible to generalise to GPs in Denmark as to how “Motivational interviewing” was implemented, how the method was used in the daily work in general practice, and which effect the methods had. Furthermore, the use of “Motivational interviewing” is not limited to certain types of counsellors, i.e. GPs, psychologists etc., as shown in Chapter 2. Thereby, the effect of “Motivational interviewing” may be generalised to a hospital setting, however keeping in mind, that the method requires training and a continuum in the patient-doctor relationship. Thus, generalisation is probably limited to consultants because of their possibility of meeting the same patient in a treatment continuum. Furthermore, motivating and changing behaviour in patients with Type 2 diabetes allows for generalisation to other disease areas. 71 72 Chapter 7 General discussion of results 73 Introduction Analysis of the data obtained in the PhD study has addressed the research questions put forward in the aim of the PhD study stated in the general introduction (Chapter 1, page 2). The results and the analysis have been discussed in detail in the Chapters 3 to 5. This chapter will review the results and offer an overall discussion in relation to current literature. Discussion of results Condition for obtaining an effect of the training course in “Motivational interviewing” The training in “Motivational interviewing” was to be learned through active participation in a residential course. This course gave introductions to the different techniques of “Motivational interviewing” and it presupposed a high level of participation in subsequent groups, workshops and role-plays. Thus, it may be a difficult process as a teacher to choose the way to present and train a concept including a specific method and technique at the course 132;157;163;169;188. Thus, different demands have to be evaluated and accommodated to design the course in the best way possible. In this process, subjects like teaching resources, incentives helping the GPs to set aside time for the courses and the contents of the course are crucial elements. Residential courses in “Motivational interviewing” had previously been conducted several times by Professor Carl Erik Mabeck, and GPs had attended these courses. Course evaluations had been positive but the courses had not been validated or been a part of a research study. In this study it was chosen to train the GPs by using the same course, course curriculum and Professor Carl Erik Mabeck as teacher (Chapter 3, page 26) 2;89 . The strategy of these courses, combining various multifaceted approaches (cognitive, behavioural and affective components) and training the methods of “Motivational interviewing” had been described in previous studies 189-191. Multiple theories and strategies have been proposed on how to achieve behaviour change and obtain adherence to methods 1;2;4;90;104;106;128;129;142;144;192-210. All these theories and strategies, including the “Motivational interviewing”, have similarities, e.g. that behavioural change and adherence is achieved only by reaching a plan accepted by both the patient and the GP, allowing treatment decisions to be based on mutual understanding between the patient and the GP 98;189-191;211-218. It was deemed necessary for the intervention to obtain effect and have a sustained effect not only to conduct the course with a view to launching a process of professional behaviour change, but also to maintain the potential effect through follow-up meetings supervised by Professor Carl Erik Mabeck. All GPs scheduled for the course during the study participated and with only few exceptions all GPs attended the follow-up days. However, GPs were not supplied with further support in maintaining the use of “Motivational interviewing” or tools for self-evaluation in order to prevent lack of adherence to the method. Besides this, the teaching style may also influence the implementation and use of the methods. Thus, an ineffective teaching style (in terms of teachers’ pedagogical abilities, contents and teaching method, size of teaching group) may also decrease the use of “Motivational interviewing” and thereby influence the effect on the patients’ risk profile. However, the GPs found that the course had provided them with skills that afforded them great confidence in using ”Motivational interviewing” for patient treatment. It may, of course, be possible that availability of continuous supervision groups and self-evaluation methods would have increased the implementation and the use of “Motivational interviewing” even further. 74 Effect of ”Motivational interviewing” on general practitioners When focusing on the first level of change upon introducing “Motivational interviewing”, i.e. change of professional behaviour among the GPs, this study showed that a ”Motivational interviewing” course influence GPs’ professional behaviour, thus providing the GPs with skills that afford them greater confidence in using ”Motivational interviewing” for patient treatment. In addition to this, GPs found that ”Motivational interviewing” was more effective than “traditional advice giving” and that it improved the patient-doctor relationship. Furthermore, the experienced GPs used the more complex parts of ”Motivational interviewing”. The GPs using ”Motivational interviewing” found that the methods was not more time-consuming and that they de facto used the same or fewer consultation encounters than GPs resorting to “traditional advice giving” 103. than “traditional advice giving”. This has also been found in previous studies 88;98;219;220. However, the study provided no specific measuring of the actual use of “Motivational interviewing” or the extent to which the GPs adhered to the methods. Therefore, it cannot be determined, on basis of the GPs’ self-rated use of “Motivational interviewing”, whether the poor effect on the patient risk profile was due to the concept of “Motivational interviewing” or to poor implementation of the method by the GPs. In order to conclude on the specific use of “Motivational interviewing” and adherence to the methods, direct measuring method is required, e.g. video recordings of counselling encounters, as discussed in Chapter 6, Intervention, page 64. However, as described above, the study showed that GPs self-rated an effect of a course in “Motivational interviewing” on their professional behaviour and on their use of the method. Thus, no effect on the patient risk profile may be caused by the limited observation period of change in patient behaviour as discussed below. Besides this, the lacking effect on patient risk profile may reflect our choice of GPs in the I- and Cgroup. The study control group comprised GPs who were trained in intensive treatment of Type 2 diabetes, including giving advice on behaviour change. Thus, GPs in C-group were not supposed to use “Motivational interviewing”, but they were urged to act as counsellors for the patients, giving them advice on how to reduce the risk of late diabetic complications and letting the treatment decisions to be based on mutual understanding between the patient and the GP (Chapter 3, page 26). Thus, some of these GPs may have used elements from “Motivational interviewing”, which may have reduced the effect of “Motivational interviewing”. The lacking effect of “Motivational interviewing” may also be ascribed to GPs failure to use all the potential three motivational consultations made available by the study. GPs in the I- and C-group on average used only one prophylactic consultation for each patient. This may be an indicator for poor implementation of “Motivational interviewing” and use of the method by the GPs. Thus, the possibility of an effect on the risk profile would have been greater if the GPs in I-group had used all three consultations deploying “Motivational interviewing”. Effect of ”Motivational interviewing” on patient behaviour change and patient risk profile The effect of “Motivational interviewing” at the second level, i.e. change at the level of patient behaviour (e.g. lifestyle behaviour, adherence to prescribed medication), was monitored in terms of self-rated change (e.g. smoking and alcohol status) and effect measures external to the patient (e.g. use of prescribed medication) (Chapters 4 and 5). This enabled us to evaluate the patient’s contemplation and readiness to change behaviour and the changes in behaviour that actual occurred. The study showed significant an effect of “Motivational interviewing” on self-rated patient behaviour with patients becoming more motivated for change and for sustaining behavioural change. The study obtained a statistically significant effect of ”Motivational Interviewing” on patients’ beliefs regarding Type 2 diabetes and on patients’ contemplation and readiness to behaviour change. However, even though the effect was statistically significant, it was small, and 75 the importance of this finding in the clinical setting remains uncertain. The study showed no effect on actual changes in smoking and alcohol intake behaviour. In relation to change of alcohol intake behaviour, this may be caused by the fact that more than 98% of the patient population were within treatment goals from study onset which left only little room for demonstrating effect of “Motivational interviewing”. The study showed a tendency that more GPs in I-group than C-group asked the patients about smoking status and behaviour (Chapter 4, Table 3, page 44). However, no change was found in smoking behaviour, which may be caused by the GPs not using the opportunity to focus on smoking behaviour or the GPs not motivating for smoking behaviour change. The patients’ statements indicated the latter, thus, that they were not motivated to change smoking behaviour. Whether this was a result of GPs including many subjects (e.g. smoking behaviour, lifestyle behaviour, Type 2 diabetes self-care etc.) in the same counselling encounter, or if it was their use of the “Motivational interviewing”, or the concept of “Motivational interviewing” itself, was difficult to determine for certain. However, overall the patients found themselves to be more motivated for changing behaviour, thus it seems as “Motivational interviewing” has effect on the patients contemplation of behaviour change. Whether “Motivational interviewing” will induce measurable change in patient behaviour needs to be evaluated on a long-term follow-up period as planned in the ADDITION-study. At the third level, changes were evaluated in terms of specific measures of the patient’ risk profile, in which no effect of “Motivational interviewing” were found. It cannot be established for certain whether this is a result of lacking effect of “Motivational interviewing”, lacking use or adherence to “Motivational interviewing” from the GPs or if it is due to the limitations of the study design, e.g. the limited observation period of 1-year follow-up as previously discussed (Design, Page 62). The review and the meta-analysis showed that a number of studies with a 1-year follow-up period had an effect on patient outcome measures (Chapter 2). However, neither of these studies intervened on diabetes, but were related primarily to alcohol treatment performed by trained psychologists familiar with the methods of “Motivational interviewing” before study onset 15;16;23;31;33;4749;54;62;66;67;72;74 . Only a few studies with a 1-year follow-up period and GPs as counsellor have been 21;45;46;51 . These studies showed effect, however, none of these focused on diabetes, but conducted on other different subjects 21;45;46;51. In all of these studies, the GPs were trained and familiar with the methods of “Motivational interviewing” before onset of the study, and they were thus focusing from study onset on patient behaviour change and patient outcome 21;45;46;51. It is possible that an effect on the patients’ risk profile might have been obtained within the 1-year study period if GPs had been trained and had been familiar with “Motivational interviewing” before the study was launched. The lack of effect on outcome may also have been shaped by the the patient population (newly diagnosed Type 2 diabetes patients detected by screening), the actual number of included patients, and the large proportion of patients within treatment goal from onset of study. As discussed in the section “Statistical methods” (page 69), this left little room for demonstrating an effect of ”Motivational interviewing”. The study showed effect of “Motivational interviewing on the first level, the GPs professional behaviour and use of the method, and on the second level on the patients contemplation of behaviour change. The uncertainty on what caused no effect on patient risk profile may simply reflect how much effect the “Motivational interviewing” method accomplished in the process of change within the follow-up period the first year. 76 Chapter 8 Conclusion 77 Conclusion Chapters 6 and 7 have discussed the methods and results of the PhD thesis. Chapter 8 presents the overall conclusion of the PhD thesis The review shows that “Motivational interviewing” has been used in treatment of various lifestyles and diseases, and 3 out of 4 studies obtained an effect no matter biological or psychological disease as shown in the meta-analysis (Chapter 2, page 17). “Motivational interviewing” has an effect not only according to questionnaires, but also measured in terms of epidemiological and clinical measures and endpoints. “Motivational interviewing” can be effective even in brief encounters of 15 min. and the likelihood of an effect rises with the number of counselling encounters. “Motivational interviewing” can be utilized with equal effect by physicians, GPs, psychiatrists and psychologists. The PhD study shows that a ”Motivational interviewing” course seems to influence GPs’ professional behaviour. GPs found that the course provided them with skills that afforded them greater confidence in using ”Motivational interviewing” for patient treatment. GPs also found that ”Motivational interviewing” was more effective than “traditional advice giving” and that it improved the patient-doctor relationship. Furthermore, the experienced GPs found that the method was not more time-consuming than “traditional advice giving”. The study obtained a statistically significant effect of ”Motivational Interviewing” on patients’ beliefs regarding Type 2 diabetes and on patients’ contemplation and readiness to behaviour change. However, even though the effect was statistically significant, it was small, and the importance of this finding in the clinical setting remains uncertain. The study did not show an effect of “Motivational interviewing” on actual lifestyle behaviour or on the risk profile in patients with Type 2 diabetes detected by screening. The process of behaviour change in general practice is elicited and supported by different methods, e.g. “Motivational interviewing” 143;221-224. “Motivational interviewing” is a promising approach for changing and sustaining altered patient behaviour 88;220. A meta-analysis concludes that psychological therapies like “Motivational interviewing” can improve long-term glycaemic control 131 . Previous studies have also pointed to the need for more research on innovative approaches like “Motivational interviewing” to assist patient behaviour change and sustain adherence, and on methods for integration of such approaches into clinical settings, clinical guidelines and into the health care system 127;225-227. Thus, previous studies side with the results of the present study on GPs’ professional behaviour and patient behaviour (Chapters 2 and 3) in supporting the need for long-term evaluation of the effect of ”Motivational interviewing” on the risk profile. 78 Chapter 9 Perspectives and implications for future research and practice 79 Perspectives Implications for future research Previous research and use of “Motivational interviewing” has increasingly embraced aspects from other psychological models of behaviour change and different approaches for managing the patientdoctor relationship. In order for future research to be able to recommend guidelines on how to use “Motivational interviewing” in practice, it is imperative that it makes an effort to describe exactly how the counsellor is educated and trained, which methods are used and in what ways “Motivational interviewing” have been applied in the counselling. This would improve the knowledge on “what proved effective” and it would allow us to recommend to future counsellors “what to do in your present encounter with a patient in need for change”. In the process of analysing how and “where” “Motivational interviewing” will be effect, future research would benefit from a detailed discussion of models for implementation of “the method” in clinical setting, and the extent of generalisation from the project to other clinical settings. Implications for practice “Motivational interviewing” is not limited to counselling of a small group of selected clients or use by certain types of counsellors. Given the assumption that future research is able to provide more specific recommendations on how to use “Motivational interviewing”, it becomes important to clarify what is needed in order to initiate the process by changing professional behaviour. This study showed that the use of a training programme requires an effort to sustain the spirit, enthusiasm and motivation of the professionals. Immediately after the course, it is “fun” to adapt and apply new methods. However, as time passes, it becomes increasingly difficult to sustain a professional behaviour change, if the professional does not have visual “sight” of the advantages of using the method. This may be assured by 1) listing progress in patient treatment, 2) using standardised methods of self-evaluation, e.g. video-recordings, 3) establishing supervision groups, and 4) by changing the organisational level in order to facilitate the process. 80 Chapter 10 English summary 81 This PhD thesis is a part of the ADDITION-study, Anglo-Danish-Ducth study of intensive treatment in people with screen-detected diabetes in primary care, which was developed and implemented in cooperation between the Department of General Practice and the Steno Diabetes Centre. This PhD thesis includes a 1-year follow-up of the effect of “Motivational interviewing” on newly diagnosed Type 2 diabetes patients detected by screening undergoing intensive polypharmacological treatment. This thesis focuses on whether GPs using “Motivational interviewing” can increase adherence to and effect of intensive treatment of Type 2 diabetes patients risk profile, thus reaching treatment goals. The PhD study was enrolled in 2001 and this thesis was submitted in 2004. General introduction The PhD thesis consist of a general introduction, four articles, a discussion of methods and results and a conclusion with perspectives and presentation of future implications for research and practice. Chapter 1 introduces the concept and methods of “Motivational interviewing”. This PhD thesis is based on the definition of “Motivational interviewing” by Miller & Rollnick, described in 1991 and elaborated in 2002. It has been used and evaluated internationally, especially during the last decade in relation to the following main areas 1) addiction (alcohol abuse and addiction to drugs), 2) change in lifestyle (smoking cessation, weight-loss, physical activity, asthma and diabetes treatment), and 3) adherence (to treatment and to control, encounters of follow-up, counselling meetings). “Motivational interviewing” has been deployed by various health care providers, including psychologist, doctors, nurses, dieticians and midwifes. However, current studies have focused on the effect of “Motivational interviewing” in a hospital setting with no or little attention to how the methods could be implemented and applied afterward in daily clinical work. This thesis focuses on the effect of “Motivational interviewing” in general practice. “Motivational interviewing” has only recently been introduced in Denmark, but its use has been rising over the past years and it has been deployed in different scientific and clinical settings. Thus, in 2000 the Danish College of General Practitioners issued an introduction booklet on “Motivational interviewing” 11, which was mailed to all members of the Danish Medical Association. Furthermore, a Danish book on the subject was issued in more than 10000 copies 12 and more than 30 residential courses in “Motivational interviewing” have been conducted by Professor Carl Erik Mabeck since. These courses attracted mainly nurses, however, a number of GPs also attended the courses with a view to use the methods in general practice. Thus, a significant effort has been made in order to enhance the use of “Motivational interviewing” in Denmark. However, no research on the effect of this effort has so far been attempted. Aim of PhD thesis The overall aim of this PhD thesis was to evaluate the effect of a course in “Motivational interviewing” on intensive treatment of Type 2 diabetes patients detected by screening in general practice. Furthermore, the PhD study aimed at evaluating: 1. The effectiveness of “Motivational Interviewing” as an intervention tool in previous randomised controlled clinical trials (RCT) and to identify factors shaping outcomes in the areas reviewed. 2. In which way a 1½-day course in “Motivational interviewing” and subsequent follow-up meetings influenced the GPs’ professional behaviour. 82 3. If the GPs having participated in a course in “Motivational interviewing” found the method applicable and useful in general practice. 4. If “Motivational Interviewing” in general practice can improve patients’ a) contemplation and readiness to change behaviour, b) their actual change in patient behaviour, and c) their beliefs about Type 2 diabetes treatment. 5. If a course in “Motivational interviewing” for GPs can improve the risk profile of Type 2 diabetes patients detected by screening. Motivational interviewing, a systematic review and a meta-analysis. (Article 1) Chapter 2 describes the background of “Motivational interviewing”, reviews the literature and performs a meta-analysis on previous studies. Its aim is to evaluate the effectiveness of “Motivational interviewing” in different disease areas and to identify factors shaping outcomes. The meta-analysis showed a significant effect of “Motivational interviewing” for combined effect estimates for BMI, total serum-cholesterol, systolic blood pressure, blood alcohol concentration, standard ethanol content, while combined effect estimates for cigarettes per day and for HbA1c were non-significant. “Motivational interviewing” had a significant and clinically relevant effect in approximately 3 out of 4 studies with equal effect on biological (72%) and psychological diseases (75%). Psychologists and medical doctors obtained an effect in approximately 80% of the studies, while other health care providers obtained an effect in 46% of the studies. How does an education and training course in “Motivational interviewing” influence general practitioner’s professional behaviour. (Article 2) Chapter 3 examines the first level in the process of measuring the effect of “Motivational interviewing”. It presents the results of how a 1½-day course in “Motivational interviewing” including follow-up meetings influenced GPs’ professional behaviour and GPs’ evaluation of the usefulness of the course in general practice. The study showed that a ”Motivational interviewing” course influenced GPs’ professional behaviour. GPs found that the course provided them with skills that afforded them greater confidence in using ”Motivational interviewing” for patient treatment. GPs found that ”Motivational interviewing” was more effective than “traditional advice giving” and that it improved the patient-doctor relationship. Furthermore, the experienced GPs used more complex parts of ”Motivational interviewing” and found that the methods was not more timeconsuming than “traditional advice giving”. Effect of motivational interviewing on beliefs and behaviour among people with Type 2 diabetes detected by screening. (Article 3) Chapter 4 analyses the second level in the process of measuring the effect of “Motivational interviewing”. It brings the results of screen-detected Type 2 diabetes patients’ evaluation of the effect of “Motivational interviewing” in terms of the patients’ self-reported 1) contemplation and readiness to change behaviour, 2) their actual behaviour change, and 3) their beliefs regarding Type 2 diabetes. The study showed a statistically significant effect of ”Motivational Interviewing” on patients’ beliefs regarding Type 2 diabetes and on their contemplation and readiness to behaviour change. However, both groups obtained effects, and even though effect of ”Motivational Interviewing” was statistically significant, it was a small additional effect. Thus, the importance of this finding in the clinical setting is uncertain. The study did not show any significant changes in lifestyle behaviour. 83 No effect of the motivational interview on risk profile in people with Type 2 diabetes detected by screening. A one year follow-up of a RCT. (Article 4) Chapter 5 presents the third level in the process of measuring the effect of “Motivational interviewing”. It analyses whether a course in “Motivational interviewing” for GPs improved adherence to intensive treatment based on evaluation of risk profile in patients with Type 2 diabetes detected by screening. The study showed no effect of the motivational interview on the risk profile of patients with Type 2 diabetes detected by screening at the 1-year follow-up. Previous studies side with the results of the present study on GPs’ professional behaviour and patient behaviour in supporting the need for long-term evaluation of the effect of ”Motivational interviewing” on the risk profile. General discussion of methods. Chapter 6 provides an overall discussion of the methods of the study applied at the various levels of the process. These methods are also discussed separately in the four articles (Chapters 2 to 5). The discussion is divided into headings: Setting, Design, Intervention, Measuring methods, Statistical methods and Generalisation. The difficulties of evaluating a training programme are discussed. General discussion of results. Chapter 7 comprises a discussion of all the results of the study obtained at the different levels of the study process: results which are presented separately in the four articles (Chapter 2 to 5). The results are discussed in relation to current literature and accomplishments are detailed. The discussion is structured into headings: 1) condition for obtaining an effect of the training course in “Motivational interviewing”, 2) effect of “Motivational interviewing” on general practitioners, and 3) effect of “Motivational interviewing” on patient behaviour change and patient risk profile. Conclusion. Chapter 8 presents the overall conclusions of this PhD study. “Motivational interviewing” has been used in treatment of various lifestyles and diseases, and 3 out of 4 studies obtained an effect no matter biological or psychological disease as shown in the meta-analysis. The PhD study shows that a ”Motivational interviewing” course seems to influence GPs’ professional behaviour. Furthermore, the study obtained a statistically significant effect of ”Motivational Interviewing” on patients’ beliefs regarding Type 2 diabetes and on patients’ contemplation and readiness to behaviour change. However, the study did not show an effect of “Motivational interviewing” on the risk profile Perspectives and implications for future research and practice. Chapter 9 draw the methods, results and conclusions of this PhD study into perspective and underscore the implications and recommendations for the future, divided into issues for research and practice. 84 Chapter 11 Dansk resumé 85 PhD afhandlingen er en del af ADDITION-studiet og baseret på projektet “Effekten af den motiverende samtale i intensive behandling af Type 2 diabetes”. Studiet blev afviklet i 2 amter, København og Aarhus, Danmark. Studiet blev startet og styret i samarbejde mellem Institut og Forskningsenhed for Almen Medicin, Aarhus Universitet og Steno Diabetes Center, Gentofte. PhD studiet inkluderer en 1-års opfølgning på effekten af ”den motiverende samtale” på screenede nydiagnosticerede Type 2 diabetes patienter intensivt behandlet. PhD studiet fokuserer på effekten af ”den motiverende samtale på adherence og effekten af intensiv medicinsk behandling af Type 2 diabetes patienternes risiko profil. PhD studiet blev indskrevet og optaget i 2001 og PhD afhandlingen blev indleveret i 2004. Introduktion PhD afhandlingen består af en generel introduktion, 4 artikler, en generel diskussion af metode og resultater med konklusion, samt perspektivering med anbefalinger i forhold til fremtidig forskning og fremtidig lægepraksis. Kapitel 1 introducerer til de grundlæggende elementer af ”den motiverende samtale”. Denne PhD afhandling er baseret på Miller & Rollnicks definition af ”den motiverende samtale”, beskrevet i 1991 og uddybet i 2002. ”Den motiverende samtale har været brugt og blevet evalueret internationalt i den seneste årrække i relation til 1) misbrug (alkohol misbrug og stof misbrug), 2) livsstilsadfærd (rygning, overvægt, manglende fysisk aktivitet, astma og diabetes behandling), og 3) adherence (til behandling og kontrolforløb). ”Den motiverende samtale” er blevet anvendt af mange forskellige behandlere, blandt andet psykologer, læger, sygeplejersker, diætister og jordmødre. Tidligere studier har udelukkende arbejdet med effekten af ”den motiverende samtale” i hospitalssystemet uden at være opmærksom på hvordan denne metode kunne implementeres og anvendes i hverdagens kliniske arbejde efterfølgende. I Danmark er anvendelsen af ”den motiverende samtale” som metode relativt ny, dog er den over de seneste 5 år blevet mere udbredt. I år 2000 udgav Dansk Selskab for Almen Medicin en klaringsrapport med vejledning i anvendelsen af ”den motiverende samtale”, som blev udsendt til samtlige medlemmer af den Danske Lægeforening. Desuden blev der udgivet en dansk bog på området, som blev solgt i mere end 10.000 eksemplarer og endelig er der afholdt mere end 30 internats kurser i ”den motiverende samtale” af Professor Carl Erik Mabeck. Disse kurser har været målrettet til fag personer indenfor sundhedssektoren, men hoveddelen af deltagerne har været sygeplejersker. Enkelte kurser er blevet afholdt primært målrettet mod praktiserende læger. Der er således brugt store ressourcer på at indføre og forstærke brugen af ”den motiverende samtale” i Danmark. Indtil nu er der ikke udført forskning på effekten af ”den motiverende samtale” i Danmark. Formål med PhD afhandlingen. Det overordnede formål med PhD afhandlingen var at evaluere effekten af et kursus i ”den motiverende samtale” på intensiv behandling af screenede nydiagnosticerede Type 2 diabetes patienter i almen praksis. Derudover havde PhD studiet til formål at evaluere om: 1. Effekten af ”den motiverende samtale” som intervention i tidligere randomiserede kontrollerede forsøg, samt hvilke faktorer som påvirker effekten af ”den motiverende samtale”. 86 2. Hvordan et 1½-dags kursus i ”den motiverende samtale” påvirker praktiserende lægers professionelle adfærd. 3. De praktiserende læger efter et kursus i ”den motiverende samtale” finder disse metoder anvendelige og mulige at integrere i deres kliniske arbejde i almen praksis. 4. “Den motiverende samtale” i almen praksis forbedrer Type 2 diabetes patienters a) parathed til at ændre livsstil, b) deres aktuelle ændringer i livsstil og adfærd, samt c) deres overbevisning og forståelse af Type 2 diabetes sygdommen. 5. Et kursus i “den motiverende samtale” til praktiserende læger forbedrer Type 2 diabetes patienters risiko profil. Den motiverende samtale, et systematisk review og en meta-analyse. (Artikel 1) Kapitel 2 beskriver baggrunden for ”den motiverende samtale” med en kritisk gennemgang af litteraturen, samt præsenterer en meta-analyse baseret på de tilgængelige data. Målet var at evaluere effekten af ”den motiverende samtale” set i forhold til forskellige sygdomsområder og desuden at identificere de mulige faktorer, som påvirker effekten. Meta-analysen påviste signifikant effekt (95%CI) af ”den motiverende samtale” for det kombinerede effekt estimat for body mass index (BMI), blod total-cholesterol, systolisk blodtryk, blod alkohol koncentration, standard ethanol indhold, imens kombinerede effekt estimat for cigaretter pr. dag og HbA1c var non-signifikant. ”Den motiverende samtale” vist signifikant og klinisk relevant effekt i omtrent 3 ud af 4 studier uafhængigt af om det drejede sig om biologiske/somatiske (72%) eller psykologiske/ psykosomatiske (74%) sygdomme. Psykologer og læger opnåede ens effekt (80%) i studierne, hvorimod andre sundheds faggrupper opnåede mindre effekt (46%) i studierne. Hvordan påvirker et kursus i ”den motiverende samtale” praktiserende lægers professionelle adfærd. (Artikel 2) Kapitel 3 undersøger det første niveau i processen af at måle effekt af ”den motiverende samtale”. Her vises resultaterne af hvordan et 1½-dags internats kursus i ”den motiverende samtale påvirkede de praktiserende lægers professionelle adfærd, samt deres evaluering af metodernes anvendelighed et år efter kurset. Studiet viste, at ”den motiverende samtale” påvirker praktiserende lægers professionelle adfærd. De praktiserende læger fandt, at kurset medførte kompetence til at anvende metoden i patientbehandlingen. Desuden fandt de praktiserende læger at metoden ”den motiverende samtale” var mere effektiv end deres vanlige rådgivning/samtaleteknik og at det forbedrede patientlæge forholdet. Endelig angav de praktiserende læger, at anvendelse af ”den motiverende samtale” ikke var mere tidskrævende end deres vanlige samtaler Effekten af “den motiverende samtale” på screenede Type 2 diabetes patienters overbevisning og adfærd. (Artikel 3) Kapitel 4 undersøger det andet niveau i processen af at måle effekt af ”den motiverende samtale”. Her bringes resultater af de screenede nydiagnosticerede Type 2 diabetes patienters evaluering af effekten af ”den motiverende samtale” på patienternes 1) holdning og parathed til at ændre adfærd, 2) på deres aktuelle ændringer i livsstil, og 3) på deres overbevisning og forståelse for Type 2 diabetes sygdommen. Studiet dokumenterede statistisk signifikant effekt af ”den motiverende samtale” på patienternes overbevisning og forståelse af sygdommen og dens konsekvenser, samt deres overvejelser og parathed til at ændre adfærd. PhD studiet påviste dog effekt i begge grupper, og den signifikante effekt af ”den motiverende samtale” var ”lille”, hvilket medfører, at den kliniske betydning af dette fund er usikker. Studiet påviste ingen ændringer i livsstilsadfærd i form af fx rygestop. 87 Ingen effekt af ”den motiverende samtale” på screenede Type 2 diabetes patienters’ risiko profil. En 1-års opfølgning af et randomiseret kontrolleret forsøg. (Artikel 4) Kapitel 5 undersøger det tredje niveau i processen af at måle effekt af ”den motiverende samtale”. Her angives i hvilket omfang ”den motiverende samtale” gennem ændring af ”faglig adfærd” og herefter patient adfærd medførte effekt på patienternes risiko profil. Studiet kunne ikke påvise ændring i risiko profil efter 1 år på screenede nydiagnosticerede Type 2 diabetes patienter. Tidligere studier støtter sammen med resultaterne fra dette PhD studie, at det er nødvendigt at foretage lang tids evaluering af ”den motiverende samtales’” effekt på risiko profil. Generel diskussion af metoderne Kapitel 6 diskuterer de metoder studiet har anvendt til at evaluere processen på de forskellige niveauer, hver især publiceret i de 4 artikler (Kapitel 2 til 5). Afsnittet tillader en mere detaljeret diskussion, som indgående omhandler alle aspekter set i forhold til diskussionsafsnittet af hver enkelt artikel. Diskussionen er inddelt i overskrifterne: setting, design, intervention, måle metoder, statistiske metoder og generalisering. Problemstillinger i forbindelse med evaluering af et uddannelsesprogram diskuteres, samt hvordan studiet har forsøgt at løse disse problemer og på hvilken måde metoderne opfyldte kravene til evaluering af alle niveauer i denne proces. Generel diskussion af resultater Kapitel 7 indeholder en diskussion af studiets resultater på de forskellige niveauer i processen, som alle er publiceret i de 4 artikler (Kapitel 2 til 5). Resultaterne diskuteres i forhold til litteraturen på området. Diskussionen er struktureret i overskrifterne: 1) forhold som påvirker muligheden for at opnå effekt af et kursus i ”den motiverende samtale”, 2) effekten af ”den motiverende samtale” på praktiserende læger, og 3) effekten af ”den motiverende samtale” på patienternes ændring i adfærd, samt ændring i deres risiko profil. Konklusion Kapitel 8 præsenterer et resumé af konklusionerne fra diskussionen af metoder og resultater i PhD studiet, samt desuden en overordnet diskussion. ”Den motiverende samtale” har været anvendt i behandlingen af mange forskellige adfærdsområder og har vist signifikant og klinisk relevant effekt i omtrent 3 ud af 4 studier uafhængigt af om det drejede sig om biologiske/somatiske eller psykologiske/psykosomatiske sygdomme. Derudover viste PhD studiet, at et kursus i ”den motiverende samtale” påvirkede de praktiserende lægers professionelle adfærd til at anvende metoden. Desuden dokumenterede studiet statistisk signifikant effekt af ”den motiverende samtale” på patienternes overbevisning og forståelse af sygdommen og deres overvejelser og parathed til at ændre adfærd. Endelig påviste studiet ikke en ændring i risiko profil efter 1 år på screenede nydiagnosticerede Type 2 diabetes patienter. Perspektiver og studiets konsekvenser for fremtidig forskning og praksis Kapitel 9 sammenholder PhD studiets metoder, resultater og konklusioner i et fremtidig perspektiv og uddrager konsekvenser og anbefalinger for fremtidens forskning og klinisk praksis. 88 References 89 Reference List 1.

In addition to intensive treatment, GPs are educated and trained in centre-specific interventions to motivate adherence to lifestyle changes and medication e.g. “Motivational Interviewing” Control group Following conventional treatment according to current national guidelines Intensive treatment with no further intervention Inclusion of app. 3000 patients with Type 2 diabetes following inclusion-/exclusion criteria: All newly diagnosed Type 2 diabetes patients detected by screening, aged 40-69 years, were eligible unless they were found to have: contraindications or intolerance to study medication; a history of alcoholism, drug abuse, psychosis or other emotional problems that were likely to invalidate informed consent or adherence to treatment; malignant disease with a poor prognosis; or were pregnant or lactating. Patients previously diagnosed with diabetes were excluded. Follow up is planned for 5 years. Endpoints will include mortality, macro-vascular and micro-vascular complications, patient health status and satisfaction, process-of-care indicators and costs. Figure 2.

Øge deltagernes muligheder for at motivere patienter til adfærdsændringer, der er nødvendige for at realisere patientens ønsker om at opnå og bevare et godt helbred. Specifikke mål. Forstå det teoretiske grundlag for 'Den motiverende samtale' Opnå kendskab til, hvordan den motiverende samtale gennemføres Lære at lytte aktivt (reflective listening) Lære at etablere et bæredygtigt forhold til patienten ved hjælp af PEARLS Lære at finde patienten, hvor han/hun er ved hjælp af VA-skaler og "Forandringens hjul" Lære at anvende 'Balanceskemaet' Lære at rokke ved 'ambivalencen'. Lære at styrke patientens ressourcer (empowering) Lære at undgå 'fælderne' Undervisningsmetode: Voksenundervisning a.m. Malcolm Knowles. Adult learning is an internal process with the locus of control of that process residing in the learner, but the process can be facilitated by outside helpers. The learning is based on the assumption that you as a learner: 1. have the self-concept of being an adult and the desire and capability of taking responsibility for planning and managing your own learning with help from fellow students, the facilitator, and other helpers. It is further assumed that what you learn through your own initiative you will learn more effectively than what you learn as a requirement by others. 2. bring with you a rich background of experience that is a valuable resource both for your own learning and for the learning of fellow students. It further assumes that your experience is different from the experience of other members of the course, and that your combined experiences represent a rich pool of resources for one another’s learning. 3. are most prepared to learn those things you perceive will be most helpful in performing your life´s work and will allow you to achieve a higher level of performance. It further assumes that the facilitator has the obligation to help you make the most use of the course, using your learning contract, in order to perform more effectively. 4. are unique, along with every other member of the course, because you have your own style and pace of learning, outside commitments and pressures, goals, and internal motivations. For these reasons your learning plan and must be highly individualised. 1 1. Hvad er problemet? Spørgsmål "Hvorfor gør patienterne ikke som vi siger?" Svar: Fordi ingen voksne mennesker ændre adfærd, blot fordi vi siger det? Vi har effektive behandlinger mod en lang række sygdomme. Mindre end 50 % af patienterne tage medicinen som foreskrevet. Vores store folkesygdomme er livsstilsrelateret. Mindre end 25 % af patienterne følger vore velbegrundede opfordringer til adfærdsændringer. Dårlig adherence (compliance) er ingen naturlov. Behandleren har stor indflydelse på patientens adherence. Dårlig udnyttelse af imponerende lægevidenskabelige fremskridt er den største udfordring for sundhedsvæsenet. 3. Motivation er handlingsorienteret Motivation er parathed til at handle. Det kan være fortsættelse af en bestemt aktivitet fx motion, eller parathed til adfærdsændring fx rygestop. Motivationen udtrykker sandsynligheden for, at personen gennemfører en bestemt handling. 4. Den motiverende samtale er baseret på: • • • • • • Vi behandler ikke patienter. Når patienten er ude af døren, er det patienten, der afgør, hvad der bliver gjort. Ingen handler imod deres overbevisning. Ændre patienten overbevisning, ændre patienten adfærd. Behandleren kan ikke ordinerer ændringer i patientens overbevisning! Det er en almenmenneskelig reaktion, at forsøg på påvirkning vækker modstand. Opleves påvirkningen som forsøg på indskrænkning af selvbestemmelsesretten, forstærkes modstanden. Patientens ambivalens dvs diskrepansen mellem patienten ønsker om et godt helbred og opretholdelse af den aktuelle adfærd. Patienten stimuleres til at reflektere over diskrepansen Løsningen skal findes i et samarbejde med den enkelte patient/klient og tage udgangspunkt i forståelse af: Hvem er patienten, hvad mener patienten og hvad er hendes situation, ønsker og muligheder? Vi kan styrke patientens muligheder til at finde sine stærke sider og sine ressourcer (empowering). 2 Hvad mener patienten? Patientens overbevisning er afgørende for motivationen. Nytter det? Kan jeg? Er det umagen værd? Etik Motivational interviewing is a directive client-centred counseling approach for initiating behaviour change by helping clients to resolve ambivalence (Miller og Rollnick). Den motiverende samtale er både direktiv, non-direktiv og forhandlende • Direktiv. Patienten fastholdes i samtalen om ambivalensen. • Non-direktiv. Patienten skal selv definere sine mål. • Forhandlende: Behandleren skal sammen med patienten finde en løsning. Det er Behandlerens ansvar at informere og sikre, at patienten har forstået sin situation og sine muligheder. Det er patientens ansvar at træffe en beslutning og gennemføre den. Nogle etiske grundbegreber Teleologi (regeletik) Handlingens rigtighed er uafhængig af konsekvenserne. Ex. Vi skal respektere patientens ret til oplysning om diagnose og prognose uanset at det (efter vor opfattelse) skader patienten mere end det gavner patienten. Deontologi (konsekvensetik) Handlingens rigtighed afhænger af konsekvenserne. Ex. Patienten skal kun oplyses om diagnose og prognose, hvis det gavner ham/hende mere end det skader. Handlingen er rigtig, hvis den gavner mere end den skader. Regelutilitarisme. Reglen er rigtig, hvis den ud fra en generel og overordnet betragtning gavner mere end den skader, dvs uanset, at den kan medføre skade i enkelte tilfælde. Ex. Patienter skal altid have sandheden at vide om deres diagnose og prognose, fordi det gavner (skaber tryghed, tillid mm) mere end det skader, uanset at nogle patienter bliver slået helt i stykker. 3 5. Patient-centreret medicin Patient-centred medicine: To bridge the gab between a biomedical understanding of the patients disease and understanding the patient as an individual in a unique situation. Den kliniske diagnose Den medicinske diagnose Personen og situationen Afvigelser fra en biologisk norm (disease) Patientens oplevelser (Illness) Naturvidenskab Humanistiske videnskaber Fælles og upersonligt Individuelt Objektive kriterier Subjektive kriterier Undersøgelser Kommunikation Kvantitative data Kvalitative data 6. Hvordan kan vi hjælpe? Eksperten Rådgiveren Katalysatoren Paternalistisk Behandleren definerer problemet og finder den rigtige løsning Behandleren respekterer patientens autonomi Patienten tager ansvar for beslutningerne Behandleren tror på patientens evner til selv at finde en løsning Informerer og ordinerer en behandling Informerer og rådgiver. Overtaler. Stimulerer til refleksion. Behandleren tager ansvar for beslutninger Ansvar til patienten Ansvar til patienten Fokus på problemet Forkus på pt´s adfærd Fokus på pt’s overbevisning Sygdoms-centreret Patient-centreret 4 7. Modstand Det er en almenmenneskelig reaktion, at forsøg på påvirkning vækker modstand. Opleves påvirkningen som forsøg på indskrænkning af selvbestemmelsesretten, forstærkes modstanden. Modstand er en etikette, som behandleren sætter på klienter med visse typer af uønsket adfærd og ytringer. Behandleren opfatter modstand som et karaktertræk hos patienten - ikke som en reaktion på behandlerens forsøg på påvirkning. For patienten er modstand en naturlig, forståelig og fornuftig reaktion på behandlerens misforståelser og forsøg på overtalelse. Det kan være nyttigt at se på modstand som et signal til behandleren om, at han går for hurtigt frem. 8. Lytte aktivt At lytte aktivt (Reflective listening) betyder: • Du reflekterer non-verbalt (kropssprog og lyde) eller verbalt (brug papegøje metoden, eller hellere omskrivninger). • Du reflekterer og resumerer, hvad du har opfattet som meningen med det, patienten siger, og de følelsesmæssige reaktioner, patienten viser. • Du stimulerer patienten verbalt og non-verbalt til at fortælle. • Du lytter hypotetisk og undersøger, om du har forstået korrekt. "Er det rigtigt forstået, at ...?" • Du styrer samtalen ved at reflektere på de informationer, du anser for vigtige. 5 9. Hvad skal der til for at opnå patientens tillid? . The tree function model • Relationship building Develop, maintain, and conclude the therapeutic relationship Patient to feel cooperative, satisfied, and better • Understanding the problem Determine and monitor the nature of the problem. Data must be comprehensive, reliable, ands relevant • Agreeing in management Tell a meaningful diagnosis Negotiate and implement a plan. 10. Samtalens lag Kliché laget Formål: Bryder isen og skabe tryghed. Ex.: "Kunne du finde en parkeringsplads". "Sikken et vejr" Facts referenceramme. Meninger Følelser Formål: Forstå problemet inden for en sundhedsfaglig Ex. "Hvornår begyndte det?" " Har du haft det før?" Forstå patientens handlinger. Patientens tolkninger og opfattelse af nøglen til forståelse af hendes handlinger. . EX. Hvis patienten tolker sin hovedpine som et muligt tegn på sygdom, går hun til læge. Hvis hun tolker det som tegn på et dårligt indeklima, går hun til sin sikkerhedsrepræsentant. Hvis hun tolker det som tegn på stres, går hun til sin arbejdsgiver. Formål: Forstå, hvad det betyder for patienten. Det er patientens følelsesmæssige reaktioner, der er nøglen til forståelse af, hvad det betyder for hende. Ex. Angsten for, hvad det kan være eller udvikle sig til. 12. Tænk over noget, du gør (eller ikke gør), der ikke er godt for dit helbred, men som egentlig synes, du burde gøre anderledes af hensyn til dit helbred (fx. cykle til arbejde, dyrke mere motion, spise mindre fedt el. lign) (Vigtigt: Det skal være noget, du ikke har noget imod at fortælle om i gruppen) Hvad? 6 13. Hvad skal der til for at opnå patientens tillid? Det er spild af tid at begynde, før der er etableret et bæredygtigt forhold baseret på: PEARLS: Partnerskab. Vi skal gøre noget sammen. Empati. Vise, at du forstår, hvordan det er at være i patientens sko. Accept. Møde patienten med en positiv og uforbeholden indstilling Respekt. Viser, at du tro på, at patienten er i stand at tage ansvaret for sine beslutnigner Legitimering. Patienten tænker logisk og hans/hendes følelser er ikke forkerte. Support. Jeg er her og vil gerne hjælpe dig - også fremover. 14. Hvad er patientens motivation? Hvor vigtigt er det for dig? Angiv på en skala fra 0 til 10. Hvordan vurderer du dine muligheder for at lave om på det? Skala 0-10. 7 15. Hvor finder jeg patienten? Det er afgørende at finde patienten hvor han/hun er, og starte dér. Forandringens hjul. Forandringens hjul efter Stage of Change Model, Prochaska & DiCelemente 1. Førovervejelsesstadiet Patienten er ikke motiveret for at ændre adfærd og har derfor heller ikke tænkt på at gøre noget ved det. Der er modstand mod forandring. "Hvorfor skal jeg altid høre om …?" fornægtelse er karakteristisk. Rygeren med bronkitis mener ikke, at rygningen er et problem. Patientens indstilling kan også være en demonstration af, at patienten selv bestemmer. Strategi: Vær ikke konfronterende eller argumenterende. Spørg hellere: "Har du nogensinde overvejet at holde op med at ryge?" "Hvad var grunden til, at du tænkte på at holde op?" 2. Overvejelsesstadiet Patienten anerkender, at der er et problem og begynder at tænke på forandring. Patienten kan tale med Behandleren om det hensigtsmæssige i at ændre adfærd. Men der er tale om løse og uforpligtende planer. Rygeren kan i flere år tale om, at hun en dag vil holde op med at ryge. Det er tale om en ambivalent indstilling. Strategi: .Forsøg at afdække ambivalensen sammen med patienten. Få patienten til at reflektere over diskrepansen mellem ønsker og aktuelle adfærd. Brug balanceskemaet. Ingen forsøg på overtalelse. 3. Forberedelsesstadiet Patienten har besluttet sig til, at der skal gøres noget. "Fra på mandag vil jeg …." Men ambivalenseen er ikke afklaret. Patienten har fortsat behov for at overbevise sig selv om, at det er nyttigt , muligt og umagen værd. Strategi: Empowering. Behandleren skal styrke patientens selvtillid og tro på, at det kan lade sig gøre. Han skal også sørge for, at patienten har en realistisk vurdering af mulighederne for at løse opgaven. Det er vigtigt, at det er patienten og ikke behandleren, der beslutter, at der skal ske noget. 4. Handlingsstadiet Patienten er i gang med forandringen. Hun er holdt op med at ryge, spiser anderledes osv. Hun er motiveret. Strategi: Behandleren skal hjælpe patienten til at nå frem til den mest egnede løsning. Behandleren skal finde den rette balance mellem at påvirke patienten og motivere patienten til selv at finde løsninger på sine problemer. Hyppige kontakter kan være med til at understrege opfattelsen af, at det er vigtigt og at Behandleren går op i problemet. Blodprøver eller et vægtskema kan fungere som redskaber i selvevalueringen og giver feed-back. Lad patienten opbevare resultaterne! 5. Vedligeholdelsesstadiet Uden en stærk vilje og bevidsthed om, at indgroede vaner ikke ændres i løbet af få måneder, men over år, er der stor risiko for tilbagefald. Et vægttab fjerner ikke i sig selv årsagen til overvægt. Det er jo ikke vægten, men patientens kostvaner, der er problemet. Strategi: Behandleren skal hjælpe patienten med at identificere risici for tilbagefald og strategier for forebyggelse af tilbagefald. Det er vigtigt, at patienten er instrueret i, hvad hun skal gøre hvis, eller helst før, der er tilbagefald. 6. Tilbagefald Succes er ikke en garanti mod tilbagefald. Det er vigtigt at patienten kommer videre i "hjulet" og ikke låses fast i dette stadium. Hvad var det, der skete? Hvad skal der til for at undgå tilbagefald? Hvad skal der til, for at komme i gang igen? Det er vigtigt, at behandleren hjælper patienten til at fatte mod og vende tilbage til det overvejende stadium. Fokuser på patientens erfaringer. "Hvad var det, der gjorde det så svært?" 8 12. Balanceskemaet Skal jeg fortsætte? Eller skal jeg ændre adfærd? A. Nævn mindst 3 gode grunde for dig til at fortsætte, f. eks med at ryge. (Jeg kan lide det. Jeg tror ikke, det er muligt osv.) C. Nævn mindst 3 fordele for dig ved at ændre adfærd, f. eks holde op med at ryge. (Jeg får det bedre med min samvittighed. Mine børn bliver glade osv.) B. Nævn mindst 3 problemer for dig ved at fortsætte, f. eks med at ryge. (Det er dyrt. Det skader mit helbred osv) D. Nævn mindst 3 problemer for dig ved ændre adfærd, f. eks at holde op med at ryge (Jeg tager på i vægt. Jeg bliver umulig at omgås osv) Pas på ikke at lægge hovedvægten på B og C. Argumentation avler modargumentation. Gevinster skal være konkrete, personlige og her og nu. 13. Rokke ved ambivalensen Working with ambivalence is working with the hart of the problem. Miller & Rollnick. Ambivalens er en normal foreteelse. Målet er at få patienten til at overveje sin situation og få patienten til at ændre adfærd i retning af sine personlige mål. (hvis de er acceptable for Behandleren?) Vi kan rokke ved ambivalensen i de situationer, hvor der er et misforhold mellem patientens adfærd og patientens ønsker om et godt helbred. Tro aldrig, at patienten opfatter cost-benefit på samme måde som du! Prøv ikke at overtale patienten. Lad patienten selv komme med forslag og vær meget opmærksom på reservationer. Det er vigtigere at beskæftige sig med motiverne end med målene Behaviour is more likely to be altered if affective or value dimensions of desirability are affected. Miller & Rollnick Hvad vil patienten gerne opnå? Vægt, kolesterol, blodtryk osv er ikke et mål i sig selv. Patientens motiver kunne være: "Jeg er utilfreds med mig selv." "Jeg er træt at være så tyk". "Jeg er bange for, at det skal gå mig lige som min mor" osv Hvis patienten ændre overbevisning, ændre han/hun adfærd. Når patienten hører sig selv fortælle om mål og adfærd øges hans/hendes bevidsthed om diskrepansen. Motivationen opstår, når patienten forstår diskrepansen og er overbevist om nødvendighed og muligheder for at ændre på forholdet. 9 14. Empowering Du skal finde patientens ressourcer i stedet for kun at fokusere på patientens svage sider. Du skal hjælpe patienten til at tro på, at han/hun selv kan finde løsninger på sine problemer, og selv kan gennemføre en plan. Dig for gold. Not for shit! Sam Putnam Problem. Vores sygdomsmodel er fejlsøgende. Vi er i langt højere grad uddannet til at finde patientens svagheder, end patientens stærke sider. Empowering er udtryk for samarbejde og fordeling af ansvar og gensidig respekt. Vær med til at skabe selvtillid hos patienten. Ros er det stærkeste medikament! Rollespil. B. Hvad gør du for at bevare dit helbred? Tænk på alt. A. Du skal: 1. Rose. Du skal vise din anerkendelser for patientens indsats. Når patienten selv synes, at han/hun på trods af dårlige betingelser virkelig har gjort en indsats, skal du udtrykke din tilslutning 2. Kun stille åbne spørgsmål. Du må gerne gå tilbage i tiden. Du skal få B til at fortælle. 3. Ikke komme med gode forslag, men demonstrere, at du tror på patientens gode vilje og sunde fornuft. 10 15. Forhandle en plan. Ingen voksne mennesker ændre adfærd, blot fordi vi siger det? I skal sammen finde en løsning, men det er patienten, der skal gennemføre den. Give råd. Hvordan kan det gøres? Ikke: Hvorfor det skal gøres. Patienten afgør om dine velmente råd kan bruges. Vær ikke for ivrig. Hellere være lidt kostbar med gode råd. • Er du sikker på, at jeg er bedre til at finde på løsninger, end du selv? • Tror du, du kan bruge mine forslag? Forslag kan gives i en uforpligtende og upersonlig stil: "Det er en mulighed. Du kan måske bruge det." Fjerne barrierer. Hjælpe med at identificere og overvinde forhindringer. Vigtigt at patienten føler, at han/hun har valgmuligheder. Reagér på modstand med eftergivenhed. Prøv at forstå og lad patienten forklare. Pas på ikke at være for ivrig og negligere modstand! Hvis sukkersygepatienten har en dårlig adherence, kan du ikke løse problemet, men hjælpe patienten til at finde en løsning. Patienten er nøglen til forståelse af, hvorfor det ikke fungerer. Er patienten ikke overbevist? Er der praktiske forhindringer. Er patienten bange for bivirkninger? Minder medicinen hende for meget om sygdommen? Osv. Du skal undgå lukkede spørgsmål. Undgå argumentation. "Du burde gøre noget ved det" fører til: "Ja, men ...." - og Behandleren tror, at patienten er uinteresseret. (The confrontation-denial trap) Argumentation avler mod-argumentation. Patienten skal ikke overtales, men presses til at indse konsekvenserne og overveje situationen i lyset af dine oplysninger. Det er patienten, der skal præsentere argumenterne for adfærdsændringer. Give feedback. Feedback skal være konkret og konstruktiv. Sig hvad du synes patienten gør godt. Vær rosende og konkret. Lad være med at kritisere. Kritik skaber afstand. Kom hellere med konstruktive forslag om, hvad man også kan gøre. Styrke patientens selvtillid. Resumere. Periodiske resumeringer sikre: - at I er enige og har forstået, hvad er der er aftalt - Reinforcerer aftaler og motivationen. Rollespil. Hvad vil og kan patienten? Oplæg. Brug f. eks. balanceskemaet Hvor er du nu med din sukkersyge? Rok ved ambivalensen og brug 'empowering' Tag udgangspunkt i figuren "Vigtigheden-Kan jeg?" punkt 6. Hvad er du god til? Hvad vil du gerne opnå? Hvad skal der til for at nå målet? Hvad kan du selv gøre? Hvad vil jeg gerne have, at andre hjælper dig med? Hvad er det første, der skal ske? Hvem vil du fortælle om din beslutning? 16. Pas på fælderne 11 Ekspertrollen Jeg er eksperten på det medicinske område. Patienten er eksperten i sit liv Informationer modificeres Alle informationer tilpasses patientens begrebsverden For mange informationer For mange informationer slår hinanden ihjel (som her?) Mod-argumentation Argumentation avler mod-argumentation Skræmmebilleder Får nogle patienter til at lukke øjnene Spørgsmål-svar fælden Pas på den interessere og videbegærlige patient Utålmodighed Pas på, du ikke taber patienten undervejs Prøv ikke at løse for mange problemer på én gang Det bedste er det godes fjende! At overhøre modstand Viser patienten modstand, skal du starte med den. Patientens afvisning Prøv ikke at presse dig igennem. Det øger patientens modstand. Den nemme og flinke patient Overlader ansvaret til dig - og gør ikke noget selv! Urørlighedszonen Overtræd ikke patientens grænser. Blaming the victim Det er ikke et spørgsmål om placering af skyld, men af ansvar. 17. Vi er selv en del af processen! 12 "Min private huskeseddel" 1. Patienten handler i overensstemmelse med sin egen overbevisning. Patienten handler ikke på grundlag af informationer og min overbevisning. Patienten foretager en selvstændig tolkning af de givne informationer. Mine vurderinger og forslag tolkes sammen med mange andre informationer og påvirkninger. Resultatet af denne tolkning er afgørende for, hvordan hun handler. Hvis patienten ændrer opfattelse, ændrer han/hun adfærd i overensstemmelse hermed. Det nytter intet, at jeg er overbevist om at mine løsninger og forslag er geniale. Ingen handler imod deres egen overbevisning, heller ikke patienten. 2. Gengælder jeg patientens tillid? Med sin henvendelse viser patienten mig sin tillid. Gengælder jeg denne tillid? Opfatter jeg og behandler jeg patienten som et selvstændigt og ansvarligt menneske, der er i stand til på fornuftig vis at tage vare på egne forhold? Viser jeg, at jeg tror på hende? Hvis jeg ikke tror på, at patienten er den bedste til at løse sine problemer, hvad er det så, jeg tror på? 3. Jeg kan ikke lave om på patienten. Det kan kun patienten selv. Motivation til forandring skal komme fra patienten og ikke påduttes af mig. Det er ikke mig, der skal vurdere fordele og ulemper ved adfærdsændringer? Men jeg skal gøre mit bedste for at patienten forstår sin situation og sine muligheder. Ambivalente følelser opstår, når der er uoverensstemmelse mellem mål og adfærd. Balanceskema Det er patientens opgave at formulere og finde en løsning på sine ambivalente indstilling. Jeg forsøger at rokke ved ambivalensen med det formål at tippe balancen til fordel for en sundhedsfremmende adfærd. 4. Patienten kender sin situation og sine muligheder bedre end jeg. Jeg er eksperten på det medicinske område. Men patientens situation er unik, og hun er eksperten, når det gælder kendskab til hendes baggrund, viden, overbevisninger, værdinormer, situation, mål og ønsker. Er det mig, der har fundet en løsning på patientens problemer med udgangspunkt i mine personlige forestillinger om patientens liv? Har jeg interesseret mig for patientens problemer eller for patientens ressourcer? 5. Hvis jeg ikke finder patienten der, hvor han/hun er og starter der, opnår jeg ingenting. Kirkegaard: At man, når det i Sandhed skal lykkes En at føre et Menneske hen til et bestemt Sted, først og fremmest maa passe paa at finde ham der, hvor han er, og begynde der. Motivationens stadier. Forandringens hjul. 6. Dårlig compliance afhænger af mig 90 % af alle patienter følger ikke vores gode råd om adfærdsændringer. Det kan blive bedre. Jeg må tro på, at jeg kan gøre noget. Parathed til forandring afhænger af mig. Forsøg på overtalelse er ikke en effektiv metode til ændring af patientens adfærd. Jeg skal undgå en egentlig diskussion med patienten. Modstand mod forandring er ikke et karaktertræk hos patienten, men en reaktion på min indsats. 7. Aldrig sige "bare" 13 "Bare" røber, at jeg ikke forstår, hvorfor det er så svært for patienten Hvis det 'bare' var så let, søgte patienten ikke din hjælp. Min rolle er at være lyttende, spørgende og tilbageholdende. Med interesse og spørgsmål stimulerer jeg patienten til selv at reflekterer over sin situation og sine muligheder. 8. Gentagelse hjælper ikke. prøv noget nyt Hvis patienten ikke har handlet i overensstemmelse med mine gode råd og forslag, er der måske noget galt med dem. Ved jeg, hvorfor patienten ikke kan bruge dem? Det nytter intet med gentagelser. Prøv at finde på noget nyt. 9. Det er lettere at narre mig selv end patienten Jeg vil så gerne hjælpe og vise, at jeg kan udrette noget. Det gør mig blind og ukritisk. Al erfaring viser, at jeg uhyre let kan bilde mig ind, at patienten såmænd nok ændre mening og handler i overensstemmelse med mine gode og velmente råd, når hun får tænkt sig godt om. Der er intet erfaringsmæssigt belæg for denne opfattelse. Derimod mange, der viser, at det er forkert. Tør jeg bede patienten om at resumere, hvad vi har talt om og er nået frem til? 10.
