A prospective analysis of the relationship between childhood sexual victimization and perpetration of dating violence and sexual assault in adulthood

The majority of studies evaluating the relationship between childhood sexual assault and subsequent sexual assault perpetration by men have been conducted retrospectively and with incarcerated populations. The present study seeks to improve on previous research by prospectively investigating the relationship between childhood sexual assault and subsequent perpetration of dating violence in adulthood in men. Although there is a significant relationship between childhood sexual abuse and history of sexual assault perpetration at baseline, prospective analyses indicate that childhood sexual assault is not predictive of perpetration during the follow-up period. The role of family factors, including parental conflict resolution, is implicated in subsequent sexual aggression. These results are supportive of the idea that the effects of childhood sexual abuse may be mediated by a variety of factors.     

Differential predictors of intimate partner sexual coercion versus physical assault perpetration

ABSTRACT

The current study attempted to strengthen existing literature regarding predictors of perpetrating intimate partner sexual violence to determine if there are unique predictors of sexual violence that differentiate it from physical abuse. It was hypothesised that men’s controlling, dominant and jealousy behaviours, and verbal aggression would significantly predict increased intimate partner sexual coercion and physical assault perpetration. These predictors were expected to be more predictive of sexual coercion than physical assault perpetration. Couples were recruited from the community (N?=?159) in a cross-sectional study recruiting couples with a violent male partner. Results demonstrated that men’s controlling behaviour was a significant predictor of sexual coercion and physical assault perpetration and behavioural jealousy was a significant predictor of sexual coercion perpetration. No predictors studied better predicted sexual coercion more than physical assault perpetration. These findings suggest that sexual coercion may be another type of physical assault without unique predictors.     

A comparison of men who committed different types of sexual assault in a community sample

This study extends past research by examining predictors of different types of sexual assault perpetration in a community sample. Computer-assisted self-interviews were conducted with a representative sample of 163 men in one large urban community. As hypothesized, many variables that are significant predictors of sexual assault perpetration in college student samples were also significant predictors in this sample, including empathy, adult attachment, attitudes about casual sex, sexual dominance, alcohol consumption in sexual situations, and peer approval of forced sex. For most measures, the strongest differences were between nonassaulters and men who committed acts that met standard legal definitions of rape. Men who committed forced sexual contact and verbal coercion tended to have scores that fell in between those of the other two groups. The implications of these findings are discussed for community-based sexual assault prevention programs.     

Substance use and PTSD symptoms impact the likelihood of rape and revictimization in college women

The present study utilized a mixed retrospective and prospective design with an 8-month follow-up period to test a model of revictimization that included multiple childhood (i.e., child sexual, physical, and emotional abuse) and situational variables (i.e., substance use, sexual behavior) for predicting rape among 276 college women. It was of particular interest to determine whether traumatic responses (e.g., posttraumatic symptomatology or risky behavior) increased vulnerability for revictimization. During the 8-month follow-up period, 9% of participants were raped; 88% of assaults involved substance use by the victim. Posttraumatic stress disorder (PTSD) symptomatology predicted rape, substance use, and sexual behavior. Substance use, but not sexual behavior, mediated the relation between PTSD symptomatology and rape during the follow-up period. Sexual behavior indirectly impacted risk for rape via substance use. Results suggest that college women with PTSD symptomatology may be at greater risk for rape if they use substances to reduce distress.     

Predictors of sexual aggression among male juvenile offenders

The purpose of this study was to conduct a longitudinal examination of predictors of sexual aggression among male juvenile offenders. Four hundred and four adolescent males between the ages of 14 and 17 years were recruited from juvenile probation offices to take part in a prospective study of substance use and sexual risk. At baseline, participants completed a series of questionnaires that assessed putative risk factors for sexual aggression. They then completed a measure of sexual aggression at the 6-month follow-up period. Correlational analyses revealed that participants who reported hard drug use, more frequent alcohol and marijuana use, and less severe offenses reported engaging in more severe sexual aggression. In addition, participants who reported higher impulsivity, sensation seeking, and externalizing behaviors also reported participating in more severe sexual aggression. When these variables were included in a regression analysis, only externalizing behaviors and severity of offense uniquely predicted severity of sexual aggression at the 6-month follow-up.     

Prediction of women's utilization of resistance strategies in a sexual assault situation: a prospective study

The present study prospectively explored the predictors of resistance strategies to a sexual assault situation. Participants were assessed at the beginning of an academic quarter on a number of variables, including past history of sexual victimization, perceived risk of sexual victimization, and intentions to use specific types of resistance strategies. Only women who reported being victimized over the interim (N=68) were included in the analyses, which suggested that women's Time 1 intentions to utilize assertive resistance strategies (e.g., physically fight, run away) and offender aggression predicted women's use of assertive resistance strategies in response to the assault that occurred over the follow-up. Women's utilization of nonforceful verbal resistance (e.g., reason, plead, quarrel) was predicted by perpetrator aggression and previous sexual victimization. Women's immobility (e.g., turn cold, freeze) during the assault that took place over the interim was predicted by experiences of childhood sexual victimization and previous sexual victimization.     

Lessons learned and unanswered questions about sexual assault perpetration

The most important lesson learned about interpersonal violence in the past 20 years is the astonishingly high prevalence of sexual assault in American society. The extensiveness of unreported sexual assault has been repeatedly documented through the use of self-report data from well-constructed surveys of victims and perpetrators. In contrast, little has been learned about how to effectively reduce rates of sexual assault perpetration. Theoretically derived universal prevention programs targeted at adolescents are sorely needed.     

Effects of Masculinity,Sex, and Control on Different Types of Intimate Partner Violence Perpetration

Controlling behaviors have been found to be a significant predictor in IPV perpetration (IPV) for both males and females. Studies have also revealed the relationship between IPV perpetration and masculinity among males; however, the literature has not investigated the relationship between masculinity and IPV perpetration among females. Additionally, studies have not explored the effects of controlling behaviors and masculinity on different types of IPV, such as physical and sexual perpetration. The present study investigated the relationship between controlling behaviors, masculinity, past victimization, and three types of IPV perpetration among 167 college students. Multivariate analyses revealed significant contributions of each factor varied according to the type of IPV perpetration (psychological, physical, and sexual). Implications from the results include the development of more inclusive violence prevention and intervention programs aimed addressing the perpetration of intimate partner violence.     

Possible solutions for preventing inmate sexual Assault: Examining wardens’ beliefs

Inmate sexual assault has long been a problem within the American correctional system. Prison sex researchers have prescribed various remedies and solutions for dealing with this issue. However, few of these studies have examined wardens’ beliefs regarding possible remedies for inmate sexual assault. Using data collected from 226 wardens in 2001, this study examines the beliefs that wardens hold concerning the effectiveness of institutional policies and procedures, staff training, and increased supervision by staff on sexual assault among inmates. On average, wardens feel these possible solutions would reduce inmate sexual coercion. Multiple regression analyses reveal that race, education, percentage of inmates sexually assaulted and known by the warden, and percentage of inmates having consensual sex are statistically significant variables associated with these remedies. Support for this project was provided by a grant from the College of Justice and Safety, Eastern Kentucky University.     

Testing telephone and web surveys for studying men's sexual assault perpetration behaviors

Three pilot studies were conducted to obtain information about sexual assault perpetration from adult men in the United States. Each used the same random digit-dial sampling and recruitment strategy. One pilot was administered by telephone and two via the Web. Response rates in all pilots were low. Although results cannot be generalized beyond the sample, of the 97 men who completed the surveys, approximately 40% in each pilot reported some sexual assault behavior, broadly defined. Contrary to expectations, telephone respondents reported a wider range of sexual assault behaviors. Suggestions for improving response rates include offering a choice of participation methods.     

Epidemiological characteristics of male sexual assault in a criminological database

Sexual assault among males, compared with females, is understudied, and may also be significantly underreported. Past studies have relied primarily on population-based survey data to estimate the prevalence of sexual assault and associated health outcomes. However, survey-based studies rely primarily on self-reports of victimization and may not accurately estimate the true prevalence of male sexual assault victimization. In order to obtain a detailed assessment of sexual assault among males, criminological databases like the National Incident Based Reporting System (NIBRS) may provide an important and unique source of information. The objective of the current study was to use data from the 2001-2005 NIBRS to construct an epidemiological profile of sexual assault among males. Our results suggest that the incidence of sexual assault was higher among young males (less than 19 years of age), with approximately 90% of all cases being reported among members of this age group. Among males of all ages, forcible fondling and sodomy were the most prevalent forms of sexual assault. Results from additional analyses include age- and race-specific rates of male sexual assault, the prevalence and severity of injury, and time trends detailing incidence by time of the day and location of the incident. Our analyses show that sexual assault is experienced by males of all age groups. However, the rate of sexual assault is higher among younger males. Despite some limitations, results from this study suggest that NIBRS data may provide a important complement to survey data for understanding breadth and consequences of male sexual assault.     

A Dyadic Analysis of Partner Violence and Adult Attachment

Studies of individual attachment features have linked insecure attachment to intimate partner violence (IPV), but these studies have neither taken into account couple-level factors nor evidence of high rates of dual-partner perpetration. The current study examined three forms of IPV as a function of both partners’ adult attachment characteristics in order to better understand the maintenance of relationship violence by using a dyadic statistical design. Heterosexual couples (n = 163) were recruited from the community. Results suggest that one’s own attachment avoidance and a partner’s attachment avoidance and anxiety was associated with perpetration of physical assault. Similarly, one’s own attachment avoidance and a partner’s attachment avoidance and anxiety was associated with perpetration of psychological aggression. Attachment anxiety influenced one’s own perpetration of sexual coercion and their partner’s perpetration. Thus, functional analysis of violence in terms of attachment and risk regulation may afford targeted interventions to certain types of couples.     

Sexual victimization and health-risk behaviors: a prospective analysis of college women

The present study utilizes the National College Health Risk Behavior Survey to examine the relationship between health-risk behaviors and sexual victimization among a sample of college women. A prospective design is utilized to examine the relationship between health-risk behaviors as measured at baseline and sexual victimization during a 3-month follow-up period. After controlling for age and parents' education, a history of adolescent sexual victimization was associated with the following health-risk behaviors as measured at pretest: increased likelihood of cigarette smoking, marijuana use, suicidal ideation, experience of physical violence within a dating relationship, use of diet pills and vomiting or laxatives to lose weight, multiple sexual partners, and early sexual intercourse. Prospectively, women's history of adolescent sexual victimization was the strongest predictor of sexual victimization during the 3-month follow-up. Implications of univariate associations between early sexual intercourse, suicidal ideation, and problematic weight loss behaviors and subsequent experience of sexual victimization are discussed.     

Assessing Sexual Coercion: Survey Wording Differences and the Victimization-Perpetration Discrepancy

The current study examined the impact of item wording on self-reported sexual assault perpetration and victimization rates. The Sexual Experiences Survey (SES; Koss et al. in Journal of Consulting and Clinical Psychology, 55, 162–170, 1987) is a self-report assessment of female sexual victimization and male sexual perpetration. Studies using the SES consistently report a marked discrepancy between victimization rates and perpetration rates. The wording of the SES items asks respondents to report whether experiences occurred in the absence of female want. It was hypothesized that modified items, which did not require an analysis of female want, would yield increased male response rates compared to the original SES, but that female rates would be equivalent across versions. Parallel male and female SES items, for coercive sexual contact and intercourse, were compared with modified items. Analyses of the data confirmed the hypothesis that modified items yielded increased reports for males in the contact and intercourse conditions. Female response rates on modified items were increased in the contact condition, but not the intercourse condition. Implications of these findings were discussed.     

Risk factors for peer sexual harassment in schools

This study introduces potential risk factors for victimization and perpetration of sexual harassment among teens not previously studied. The first set of analyses compared histories of perpetration and victimization by gender, as well as the relationship between risk factors and perpetration or victimization. For girls (r = .544) and boys (r = .700), the relationships between perpetration and victimization histories were very strong. Most proposed risk factors were also significantly related to perpetration and victimization histories for both genders, including alcohol use frequency, delinquency, histories of family violence and victimization, cultural and personal power, and retaliation, with all increasing as perpetration or victimization history increased. For girls, two direct paths were moderately related to victimization--delinquency and family victimization. For boys, only one variable--perpetration history--was related to victimization history. Four variables were directly related to greater sexual harassment perpetration-greater personal power, delinquency, family violence, and family victimization.     

Exploring gender differences in dating violence/harassment prevention programming in middle schools: results from a randomized experiment

In this study, we randomly assigned 123 sixth and seventh grade classrooms from seven middle schools in the greater Cleveland area to one of two five-session curricula addressing gender violence/sexual harassment (GV/SH) or to a no-treatment control group. A baseline survey and two follow-up surveys were administered immediately after the treatment (Wave 2) and about six months post-treatment (Wave 3). In an earlier paper, we demonstrated the effectiveness of two approaches to youth GV/SH prevention programming (a fact-based, law and justice curriculum and an interaction-based curriculum). In this paper, we explored whether these largely positive findings remain for both girls and boys, including whether girls experience higher levels of GV/SH than boys. Most of our statistical models proved to be non-statistically significant. However, in 2 of our 48 victimization/perpetration (any violence, sexual violence and non-sexual violence) models (across two post-intervention follow-up points), we observed that the interventions reduced peer (male or female, non-dating partner) sexual violence victimization and reduced peer perpetration, but another outcome model indicated that the interventions increased dating perpetration. These mixed findings will need to be explored further in future research. Regarding our primary research question, we observed no statistically significant differences for the treatment multiplied by gender interaction terms for any of the perpetration or victimization outcome models, suggesting that the treatment had similar effects on girls and boys. However, we did observe that boys are more involved in violence than girls: both as victims and perpetrators. Boys experienced significantly more of three types of victimization from peers and dating partners compared to what girls experienced at the hands of their peers and dating partners. As perpetrators, boys committed more sexual victimization against peers (immediately post-intervention only) and more sexual victimization against dating partners than girls. The implications of these results are discussed.     

Why Is There a Strong Positive Correlation Between Perpetration and Being a Victim of Sexual Coercion? An Exploratory Study

The purpose of this research was to determine if the correlation between perpetration and being a victim of sexual coercion is due to a lack of self-control, a coercive lifestyle, or dysfunctional romantic relationships. Two hundred and sixty-two college students completed measures of perpetration and being a victim of sexual coercion, lack of self-control, coercive lifestyle, romantic partner’s coercive lifestyle, and partner’s perpetration and being a victim of sexual coercion. Support was not found for the lack of self-control and coercive lifestyle explanations; support was found for the dysfunctional relationships explanation. Multiple regression analyses found that the self-control variable that best (negatively) predicted both perpetration and being a victim of sexual coercion was valuing long-term, committed romantic relationships. Interventions to prevent perpetration and being a victim of sexual coercion should focus not only on the individual victim/perpetrator but also on promoting functional romantic relationships.     

Career Dimensions of Stalking Victimization and Perpetration

Prior literature concerning stalking, particularly in the field of criminology, finds wide variation in fundamental trends regarding stalking victimization and perpetration. There seems to be little consensus regarding when and how stalking is manifested. Furthermore, prior research to date has not addressed the etiology of stalking‐related behaviors by applying principles from criminal career research, including participation, frequency, onset, and duration. The present study builds upon prior research by addressing trends in age of onset for stalking victimization and perpetration, the duration of stalking‐related behaviors, and the relationship between those behaviors and other types of crime over the life course using primary data from a sample of young adults. Findings indicate that stalking victimization and perpetration share important career attribute similarities, and that self‐reported history of intimate partner violence and sexual assault are strongly associated with stalking outcomes.     

The relationship between the quantity of alcohol consumed and the severity of sexual assaults committed by college men

Researchers have suggested that intoxicated perpetrators may act more violently than other perpetrators, although empirical findings have been mixed. Past research has focused on whether or not alcohol was consumed, rather than the quantity consumed, and this may explain these inconsistent findings. The authors hypothesized that the quantity of alcohol consumed would have a curvilinear relationship to the severity of the assault. Data were collected from 113 college men who reported that they had committed a sexual assault since the age of 14. The quantity of alcohol that perpetrators consumed during the assault was linearly related to how much aggression they used and was curvilinearly related to the type of sexual assault committed. The quantity of alcohol that victims consumed during the assault was linearly related to the type of sexual assault committed. Strategies for improving assessment of alcohol consumption in sexual assault research are discussed.
