University of Nevada, Reno Research has demonstrated a relationship between childhood physical abuse and subsequent victimization in dating relationships. However a prior history of abuse does not necessarily result in revictimization and knowledge regarding the mechanisms that increase vulnerability for victimization in the form of dating violence is limited. The current study examined the relationship between child physical abuse, dating violence, general distress, and experiential avoidance, in an undergraduate student sample of 314 women. Physical abuse in childhood was associated with significantly higher rates of victimization in dating relationships, and experiential avoidance mediated the relationship between child physical abuse and revictimization. Higher levels of general distress was associated with cumulative experiences of child physical abuse and dating violence, compared with child physical abuse without dating violence. The current findings suggest that revictimization in the form of dating violence may be linked to exacerbated distress in women who are physically abused as children and that prevention and treatment programs on college campuses may benefit from targeting experiential avoidance with survivors of interpersonal trauma. Keywords: child physical abuse, dating violence, revictimization, experiential avoidance dinal correlates of dating violence and information about clinical resources. There has been less emphasis enhancing behavioral repertoires that could reduce the risk for revictimization and the impact on measurable outcomes has been limited (Cornelius & Resseguie, 2007). Because of gaps in the information on behavioral change related to risk reduction, there exists a critical need for further research in this area. The prevalence of victimization in dating relationships and related outcomes are important concerns for all young adults, and those with histories of child physical abuse face an even greater risk of victimization in dating relationships (Vézina & Hébert, 2007). Despite these observations, the research in this specific area of revictimization is limited. Among individuals with a history of interpersonal violence, little is known about the cumulative impact of physical abuse in childhood combined with the experience of dating violence, although negative outcomes have been associated with each (Amar & Gennaro, 2005; Kaplan, Pelcovitz, & Labruna, 1999; Springer, Sheridan, Kuo, & Carnes, 2007), and additional increase in distress has been documented in relation to cumulative experiences of childhood physical abuse and intimate partner violence (Banyard, Williams, & Siegel, 2001; Follette, Polusny, Bechtle, & Naugle, 1996). Additionally, the field is limited in sound theoretical formulations and empirical work examining specific factors that may explain or mediate the relationship between the victimization experiences, which could have important implications for prevention and intervention. Prevention programs aimed at reducing dating violence have primarily focused on education regarding incidence and prevalence of abuse and attitu- Dating Violence Dating violence has been identified as a pervasive problem among adolescents and young adults. Studies measuring the prevalence of dating violence in student samples suggest that approximately 20% to 48% of individuals have experienced victimization in the form of some physical violence in their dating relationships, with most studies conceptualizing violence as behaviors with intention or perceived intention of causing physical pain or injury (Amar & Gennaro, 2005; Harned, 2002). Studies examining prevalence of dating violence separately in high school and college students have estimated slightly higher rates of 20%–30% in college students, compared with 10%–25% in high school students (Cornelius & Resseguie, 2007). In one study by Chan, Straus, Brownridge, Tiwari, and Leung (2008) which consisted of a large international sample of university students from 22 different countries, the proportion of students who reported being physically assaulted by a dating partner ranged from 14% to 39%, with a median of 26%. Even higher rates have been found when a more broad definition of dating violence has been used to include psychological or emotional abuse, with one study on a sample of college and university students reporting an incidence of 79.1% for all forms of psychological abuse (DeKeseredy & Kelly, 1993).

CHILD PHYSICAL ABUSE AND DATING RELATIONSHIPS attributed in part to differences in how dating violence has been defined, the phenomenon is widespread and is of significant concern in college students as well as the general population. The experience of victimization in dating relationships can have a number of negative impacts on mental health. The range of psychological difficulties that have been suggested to have a relationship with dating violence include PTSD, depression, anxiety, substance use, disordered eating, risky sexual behavior, and suicidality (Ackard & Neumark-Sztainer, 2002; Callahan, Tolman, & Saunders, 2003; Carlson, McNutt, Choi, & Rose, 2002; Chan et al., 2008; Coker et al., 2002; Golding, 1999; Roberts, Klein, & Fisher, 2003; Silverman, Raj, Mucci, & Hathaway, 2001). Studies on women from college student populations, specifically, have also shown that those victimized in dating relationships report greater psychological distress and mental health symptoms, and reduced self-worth, compared with their nonvictimized counterparts (Amar & Gennaro, 2005; Clements, Ogle, & Sabourin, 2005; Coffey, Leitenberg, Henning, Bennett, & Jankowski, 1996). Furthermore, dating violence has been identified as a risk factor for experiencing subsequent violence in dating or marital relationships (Gagné, Lavoie, & Hebert, 2005; Hendy et al., 2003; Smith, White, & Holland, 2003). Given the increased risk for revictimization, there is need for identifying risk factors that are associated with dating violence and conceptualizing the relationship of these variables using a testable theoretical model. Revictimization: Childhood Physical Abuse as a Risk Factor The study of revictimization, defined generally in this case as the experience of victimization among those with prior histories of trauma, has received increased attention in recent years (Duckworth & Follette, 2011; Widom, Czaja, & Dutton, 2008). Studies have shown that a history of childhood physical abuse frequently acts as a risk factor for subsequent exposure to dating violence (Ehrensaft et al., 2003; Hendy et al., 2003; Stith et al., 2000; Vézina & Hébert, 2007; Whitfield, Anda, Dube, & Felitti, 2003). One study by Gover, Kaukinen, and Fox (2008) examined a large college sample of 2,305 male and female participants and found that 32% of those with histories of childhood physical abuse reported subsequent physical violence victimization in romantic relationships compared with 18% of those without such histories. The authors also found that physical abuse in childhood was associated with the increased likelihood of being victimized for women, but not for men in their sample. Despite the significant link between physical abuse in childhood and subsequent physical revictimization in the form of dating violence, there have been few empirical attempts to test specific theories to explain this relationship (Wekerle & Wolfe, 1998; Wekerle et al., 2001; Wolfe, Wekerle, Reitzel-Jaffe, & LeFebvre, 1998). Furthermore, although there is a significant increased risk for individuals who experience child abuse to experience revictimization, there is variability in outcomes, and many individuals with child abuse histories are not subsequently revictimized. This variability in outcomes suggests that we may be able to identify important risk factors that are modifiable and that can decrease the risk for revictimization. Moreover, there are other long-term impacts of child abuse that may result in comorbid outcomes that should also be considered in prevention programs (Kessler, Davis, 563 & Kendler, 1997; Spatz Widom, Dumont, & Czaja, 2007). Identifying individual factors that act as potential moderators and mediators in this relationship can lead to more targeted treatment and prevention programs. Experiential Avoidance One construct that has been conceptualized as a mediator of the relationship between childhood abuse and later victimization is experiential avoidance (EA) (Polusny & Follette, 1995). EA is defined as the process that occurs when an individual is unwilling to remain in contact with negatively evaluated private experiences (e.g., thoughts, feelings, or memories, bodily sensations, behavioral dispositions) and engages in attempts to reduce, numb, or alleviate such experiences (Hayes, Wilson, Gifford, Follette, & Strosahl, 1996). Although the use of avoidance strategies may provide some relief in the short term, research suggests that longterm use of EA results in a number of negative consequences, including depression, anxiety, and substance abuse as well as other forms of psychological distress (Hayes et al., 1996; Wilson, Follette, Hayes, & Batten, 1996). The construct of EA has been considered particularly relevant to trauma in that the exposure to significant stressors can results in a diverse range of outcomes including PTSD and problems such as depression, substance abuse, suicide, and other behaviors that are diverse in topography but that may all serve a similar function (Chapman, Gratz, & Brown, 2006; Hayes et al., 1996; Marx & Sloan, 2005; Polusny & Follette, 1995; Polusny, Rosenthal, Aban, & Follette, 2004; Salters-Pedneault, Tull, & Roemer, 2004; Tull, Gratz, Salters, & Roemer, 2004; Tull & Roemer, 2003). Conceptually, the link between early abuse and later revictimization can be understood in terms of childhood learning experiences. Childhood is thought to be a critical time period for learning emotion regulation in the context of interactions between children and their caregivers (Cole, Martin, & Dennis, 2004). Parenting practices observed in physically abusive parent– child relationships may play an integral role in the development of emotion regulation/coping capacities. High levels of EA may be especially likely to develop in the context of childhood physical abuse, because physical harm by caretakers may be accompanied by a range of aversive private experiences, where love, fear, and distrust may all be interwoven. In this context of learning and vulnerability, individuals may learn to cope with difficult private experiences by adopting a coping style marked by EA. Research has found that individuals with histories of physical abuse in childhood use EA to a greater degree than their nonabused counterparts (Gratz, Bornovalova, Delany-Brumsey, Nick, & Lejeuz, 2007). Avoidance coping has been associated with a range of trauma related outcomes by researchers using a range of theoretical orientations (Clements & Sawhney, 2000; Krause, Kaltman, Goodman, & Dutton, 2008; Swan & Snow, 2003). Theoretically, heightened and chronic reliance on EA could function to increase risk for further interpersonal violence for several reasons. Over reliance on cognitive and emotional suppression as avoidance strategies to deal with painful thoughts and emotions, including trauma related symptoms, have been associated with paradoxical increases in the thoughts being avoided and further intensification of distress. The cognitive attention that is FIORILLO, PAPA, AND FOLLETTE This document is copyrighted by the American Psychological Association or one of its allied publishers. This article is intended solely for the personal use of the individual user and is not to be disseminated broadly. 564 taken up by chronic suppression may interfere in the process of awareness to the current moment, including the ability to recognize or respond to risks in the environment. Additionally, the chronic suppression of emotions when in the context of dating relationships may prevent the individual from contacting the adaptive functions that their ongoing emotional experiences may signal, including emotions that may highlight risk or need for flight from a relationship. Furthermore, rather than relieve distress, the continuing increase in suffering associated with suppression may further overwhelm the regulating capacities of the individual who may already have problems in coping with distress in a healthy manner. In addition to internal attempts to avoid, EA can also be marked by a number of external behaviors, including alcohol use—to avoid aversive experiences, which could further disengage an individual from the current environment and contribute to the increased risk for revictimization. Despite the relevance of EA in the relationship between child physical abuse and dating violence, its role as a mediator has yet to be examined. Current Study The goals of the current research are to extend the existing empirical knowledge on dating violence, particularly as a phenomenon of revictimization in the aftermath of child physical abuse. The study uses a relatively conservative definition of dating violence by limiting the measurement of acts to physically violent behaviors, without considering acts that represent emotional abuse, and does not document the actual occurrence of bodily harm. Although all forms of physical and psychological abuse are worthy of consideration, measurement issues associated with assessing the broad range of behaviors that can be considered abusive, led us to focus on a more restricted range of physical violence. By focusing on a sample of women, this study incorporates recommendations in the literature which emphasize separate studies of men and women due to concerns about gender specific effects (Harned, 2002; Jackson, 1999; Katz, Kuffel, & Coblentz, 2002). The primary aim of the current study is to assess the role of EA in relation to dating violence and child physical abuse in a college sample. By identifying theoretical variables that could be useful in prevention and treatment programs, the study can shed light on an important problem that student health centers frequently address on college campuses. Specifically, this study tested a model of revictimization in which EA mediated the link between child physical abuse and dating violence. Additionally, the current study assessed general distress as an outcome relative to child physical abuse, dating violence, and cumulative victimization in the form of both types of interpersonal violence. The cumulative trauma model, which suggests that interpersonal victimization in both childhood and adulthood is associated with increased clinical distress beyond what is observed with single experiences of trauma, has garnered support in the trauma literature (Banyard et al., 2001; Follette et al., 1996). Such a pattern has not been previously examined with regard to cumulative experiences of child physical abuse and dating violence. Method Participants and Procedure The sample consisted of 314 undergraduate women from a midsize western state university. Participants were recruited from introductory psychology classes for extra credit via an online recruitment system that included brief information regarding the study. The number of individuals who were exposed to the initial online recruitment is not recorded, and therefore we are not able to report the rate of response. Of those participants who signed up to receive further details regarding the study, none refused to participate. The study design was cross-sectional, with participants completing the survey in a secure lab setting. To mitigate the possibility of social stigmatization and encourage honest responding, we ensured there was no identifying record of participants having taken part in the study by obtaining oral consent instead of written consent. This consent procedure was carried out with the approval of the institutional office of human research protection. Mean age of participants was 19.9, and 96% reported being heterosexual. Ethnicity of the sample was primarily Caucasian (74.5%), followed by Latina (8.9%), Asian American/Pacific Islander (7.3%), African American/Black (3.2%), Native American (1.6%), and other (4.5%), with these numbers being fairly representative of the demographics of the university as a whole. Measures Our two main outcome variables of interest were general distress and self-reported experiences of dating violence. General distress was measured with the Global Severity Index (GSI) of the widely used, Brief Symptom Inventory (BSI; Derogatis, 1975). The GSI combines information about the number of endorsed symptoms and perceived intensity level as a measure of overall psychological distress. The scale has demonstrated high test reliability for the whole scale (.90; Derogatis, 1993). In this study, Cronbach’s alpha was .96. Our other outcome was Dating Violence (DV), as measured by the16-item Safe Dates Physical Violence Victimization Scale (SDPVVS; Foshee et al., 1996). The SDPVVS measures victimization in past or current dating relationships, assessing four categories of victimization (relatively mild physical victimization, moderate physical victimization, severe physical victimization, and sexual victimization). For each item in the measure, respondents rate the frequency of their experiences on a scale from which total scores or dichotomous scores can be obtained. The measure possesses high internal consistency with Cronbach’s alpha of .91 (Foshee et al., 1998, 2000), which was consistent in the current study, with alpha of .90. Information on dating violence from the SDPVVS was used in this study to categorize participants into a DV or non-DV group. Items that were part of the mild physical violence or sexual violence subscales were not scored as DV. Our distal variable was child physical abuse as assessed with the use of the physical assault subscale of the Conflict Tactics Scale (CTS1; Straus, 1979). The CTS1 is a well validated, widely used measure in the study of family violence including physical violence in parent– child relationships (see Straus & Hamby, 1997). Participants endorsed (yes/no) if they had ever been pushed, grabbed, shoved, or slapped as a measure of lower level behaviors This document is copyrighted by the American Psychological Association or one of its allied publishers.

CHILD PHYSICAL ABUSE AND DATING RELATIONSHIPS that some consider a measure physical/corporal punishment. Experiences such as being hit, beat up, choked, and threatened with a knife or a gun were included in the measure of more serious child physical abuse (CPA). CPA was defined in this study as any endorsement of serious physical violence at the hands of family members or a caretaker on the physical abuse subscale. Because of the difficulty in clearly identifying the function, intent, and severity of behaviors that are included in the low-level violence/punishment subscale of the CTS, these were not included in our analyses. This is not meant to minimize the potential negative impact of those behaviors, but rather the more conservative definition of violence is used in order to protect against charges of overly inflated statistics of abuse. Moreover, CTS scales have subscales that were created under the presumption that the greater harm results from the acts in the more severe subscales (Straus, 2007). The distinction between the minor and severe assaults has been supported by factor analyses with a significant body of literature indicating that the etiology and treatment of minor violence differs from severe assaults (Gelles, 1991; HoltzworthMunroe & Stuart, 1994; Johnson & Ferraro, 2000). Finally, our hypothesized mediator of the relationship between CPA and adult dating violence, EA, was measured using the Acceptance and Action Questionnaire-II (AAQ-II; Bond et al., 2011). The AAQ-II demonstrates good psychometric properties with a mean Cronbach’s alpha of .84 across six samples (Bond et al., 2011), a 3- and 12-month test–retest reliability of .81 and .79, respectively (Bond et al., 2011), convergent validity with measures of general health (e.g., r ⫽ ⫺.67 with the Symptom Checklist10R), and measures of suppression and emotional disturbances (e.g., r ⫽ ⫺.75 with the Beck Depression Inventory). In our study reliability was .87 and demonstrated good convergent validity with the GSI (r ⫽ ⫺.68). Results Prior to analyses, variables were examined for accuracy of data entry. Missing values for the BSI and AAQ-II were replaced with the mean score of the remaining items, if the number of missing values were less than 5% of the total possible values (Tabachnick & Fidell, 2001). Missing values on the CTS or SDPVVS were not imputed because of the dichotomous nature of coding. Three participants did not provide sufficient information to score the CTS, and another three did not complete the SDPVVS. Two participants did not provide enough information to score the BSI, and three did not complete the AAQ-II and were excluded from our ANOVA and mediation analyses. Because the participants could submit their materials and leave the study at any point in time without need to give an explanation (a requirement of our IRB), the reasons for noncompletion of particular items are not known. Prevalence of CPA and DV One hundred thirteen women (36.7%) reported a history of child physical abuse (see Table 1), and 82 (26.6%) women reported a history of moderate to severe dating violence (see Table 2). Of the 113 women with a child abuse history, 39 (34.5%) reported a history of moderate to severe dating violence. Of the 195 who reported minor or no child abuse history, 43 (22.1%) reported 565 Table 1 Prevalence of Individual Items of Child Physical Abuse Child physical abuse item 1. 2. 3. 4. 5. 6.

Differences in the rate of dating violence among women with versus without a history of child physical abuse was significant, 2(1, 306) ⫽ 5.67, p ⬍ .05. The Relationship of CPA and DV to General Distress In order to examine the differences in levels of general distress according to each specific type of interpersonal violence and cumulative experiences of victimization, women were divided into the following four groups: (1) no child physical abuse or dating violence victimization (No CPA or DV; n ⫽ 151), (2) child physical abuse only (CPA-only; n ⫽ 74), (3) dating violence victimization only (DV-only; n ⫽ 42), and (4) both child physical abuse and dating violence victimization (CPA ⫹ DV; n ⫽ 39; Table 3). Analysis of variance indicated a significant difference in general distress between the four groups, F(3, 305) ⫽ 17.07, p ⬍ .01 (see Table 3). Post hoc analyses using the Scheffé test indicated that participants without either victimization experience (No CPA or DV; M ⫽ .51, SD ⫽ .47) differed significantly from all the other groups in the level of general distress, compared with CPAonly, F(3, 302) ⫽ 5.02, p ⬍ .01 (M ⫽ .82, SD ⫽ .58), DV-only, F(3, 302) ⫽ 6.23, p ⬍ .001 (M ⫽ .94, SD ⫽ .74), and the CPA ⫹ DV group, F(3, 302) ⫽ 12.97, p ⬍ .001 (M ⫽ 1.14, SD ⫽ .67). The CPA-only group did not differ from DV only, F(3, 302) ⫽ .39, p ⬎ .05 (Table 3). The revictimized CPA and DV group differed significantly from those with a history of CPA only, F(3, 302) ⫽ 2.42, p ⬍ .05, but did not differ significantly from the DV-only group, F(3, 302) ⫽ .55, p ⬎ .05. Thus, among those with a history of child physical abuse, revictimization in the form of dating violence was associated with greater levels of general distress compared with child physical abuse only. Does EA Mediate the Relationship Between CPA and DV? To test whether EA mediated the relationship between child physical abuse and DV victimization, we assessed a mediator model using procedures outlined by Baron and Kenny (1986). Using this method, we found that there was a significant difference in the effect of history of childhood physical abuse on DV when including EA as a mediator (c ⫽ .06, p ⬍ .05, c= ⫽ .44, p ⬎ .10, Aroian test z ⫽ 1.97, p ⬍ .05; Figure 1; Table 3). However, due to the cross sectional nature of this data, we analyzed an alternative model assessing if the relationship between childhood physical abuse and EA was mediated by history of dating violence in order to rule out reverse causal effects. The result indicated that this FIORILLO, PAPA, AND FOLLETTE 566 This document is copyrighted by the American Psychological Association or one of its allied publishers.

Consistent with prior research, the results obtained in this study show that experiencing either childhood physical abuse or dating violence, when compared with no reported history of such victimization, is associated with greater levels of psychological distress (Amar & Gennaro, 2005; Kaplan et al., 1999). The study adds to the literature on cumulative experiences of interpersonal victimization, with our findings demonstrating that a history of both child physical abuse and dating violence, is related to poorer psychological functioning, in comparison to a childhood history of physical abuse only. This finding supports the results in a growing number of studies documenting the phenomenon of cumulative distress in relationship to traumatic experiences (e.g., Follette et al., 1996; Scott-Storey, 2011). Part of what makes our study unique is the documentation that the combined experiences of child physical abuse and dating violence also can have a cumulative impact, which has not previously been investigated. Although differences were found in general distress scores between those with combined experiences of dating violence and childhood physical abuse compared with childhood physical abuse only, the combined victimization group did not differ from those with a history of dating violence only. Some researchers have discussed the possibility of differential impact of separate types of victimization on cumulative distress, suggesting that some but not all types of traumatic experiences impart an additive effect on symptoms (Scott-Storey, 2011). One potential explanation for the lack of difference between those victimized in dating relationships only compared with both types of victimization, in this sample, could be that more proximal abuse experiences will be associated with greater symptomology. An important new finding in from this research is the demonstration of the role of EA as a mediator linking childhood physical abuse and victimization in later dating relationships. This finding broadens the understanding of one specific pathway through which child physical abuse may result in greater likelihood of dating violence and highlights the importance of interventions designed to address a range of issues in the repertoires of individuals with a history of abuse. Interventions that emphasize awareness and ac- Note. Participants could endorse multiple items.

Together these analyses suggest that EA does mediate the relationship between history of childhood physical abuse and experience of DV. Discussion The results in the current study provides additional evidence that victimization in dating relationships, when considering moderate to severe physically abusive experiences, is fairly prevalent in the college student population and is associated with long-term distress. The data on rates of dating violence found in this study are consistent with prior studies, which have revealed similar rates of violence in dating relationships in undergraduate samples (Cornelius & Resseguie, 2007). The current findings also indicate that experiencing physical abuse in childhood is a distal risk factor for being victimized in dating relationships. Moreover, our finding that 26% of women with a history of child abuse in this sample Table 3 Summary of ANOVA and Follow-Up Scheffé Test for General Distress and Experiential Avoidance Variables/Groups General distress 1.

Acceptance and Commitment Therapy (ACT; Hayes, Strosahl, & Wilson, 1999) is a treatment that is particularly relevant in regard to these issues as it is designed to reduce EA and increase psychological flexibility. Moreover, ACT-based interventions can assist individuals in behavioral activation related to self-care. The emphasis on behavioral skills aimed at reducing EA could help in filling the gap that has currently been noted in prevention efforts aimed to reduce risk of victimization in dating relationships generally and also in the context of a childhood history of physical abuse. Although ACT has some preliminary data to support it as a promising therapy for trauma-related symptoms (Batten & Hayes, 2005; Twohig, 2008), there are several other treatments that focus specifically on PTSD. For instance, Cognitive Processing Therapy (CPT; Resick & Schnicke, 1992) focuses on recalling, reexperiencing, and processing trauma-related events. Although the current research provides important new data, several limitations of the study warrant attention. First of all, the current study utilized retrospective and cross-sectional methodology, which restricts the generalizability of the findings. The design, in which all the variables were assessed at a single time point, limits our ability to establish a temporal relationship between our variables of interest. Although the finding regarding the role of EA as a mediator is theoretically supported, stronger empirical demonstrations of the relationship between child physical abuse and victimization in dating relationships, and in particular the role that EA plays in increasing risk for revictimization, necessitates that utilization of longitudinal designs. Another methodological limitation inherent in this study concerns the use of self-report inventories as measurement tools. It is possible that the extent to which the variables were associated in this study may have been artificially inflated, because of possible shared method variance in measurement. In future studies, utilization of a behavioral measure of EA could counteract concerns regarding method variance. However, it should be noted that similar findings have been reported in several studies (Ghimire & Follette, 2011). 567 Because information regarding the severity and frequency of victimization experiences were not obtained, the relationship of these specific variables to the outcome could not be established. Some studies have suggested that the frequency, duration, and severity of abuse are associated with more severe long-term negative outcomes (English et al., 2005; Malinosky-Rummell & Hansen, 1992). However, the data are mixed in this area, and these inconsistencies in the literature may well be related to difficulties in reliable measurement of abuse-related variables. The lack of information regarding co-occurring victimization is also a limitation given the research literature, which indicates that it is related to poorer outcomes (Scott-Storey, 2011). Additional lack of information regarding the current relationship status of the respondents obfuscates differences that may have occurred due to reporting experiences with a current partner compared with past partners. Although we make reference to other behaviors such as substance use that may be connected to the relationship between child abuse and dating violence, we did not measure such variables in our study. Further work in the area should focus on assessment of additional variables that either moderate or mediate long-term outcomes. Although the study was composed entirely of college students, a focus on developing effective prevention and intervention programs for use on a college campus has been one important part of our work. Thus, although there are some limits to the generalizability of the data in our study, it is certainly relevant to the large numbers of students on college campuses across the country where college counseling centers are increasingly called on to provide services for a range of student problems. Limited campus resources and the need to provide interventions with some empirical foundation make it important to demonstrate areas of specific student need. The research presented here provides additional support for the specific role of EA in increasing risk for dating violence, particularly among survivors of childhood physical abuse. In addition, there is supplementary evidence for the cumulative impact of a history of repeated trauma exposure. Although efforts to identify processes that increase risk for victimization continue at an individual level, it is also important that we broaden our attention the prevention of abuse and to the larger environmental and sociopolitical context in which interpersonal violence exists.
