Long-Term Effects of Conflict-Related Sexual Violence Compared with Non-Sexual War Trauma in Female World War II Survivors

The aim of the study was to compare the long-term effects of conflict-related sexual violence experienced at the end of World War II (WWII) with non-sexual WWII trauma (e.g., being exposed to shell shock or physical violence). 

A total of 27 elderly wartime rape survivors were compared to age- and gender-matched control subjects who were drawn from a larger sample of subjects over 70 years of age who had experienced WWII-related trauma. A modified version of the Posttraumatic Diagnostic Scale was used to assess trauma characteristics and posttraumatic stress disorder (PTSD) symptoms and the Brief Symptom Inventory-18 was used to assess current psychopathology. 

Additionally, measures of posttraumatic growth (Posttraumatic Growth Inventory) and social acknowledgement as a trauma survivor (Social Acknowledgement Questionnaire) were used to assess two mediating variables in post-trauma conditions of rape victims. Women exposed to conflict-related sexual violence reported greater severity of PTSD-related avoidance and hyperarousal symptoms, as well as anxiety, compared with female long-term survivors of non-sexual WWII trauma. 

The vast majority (80.9 %) of these women also reported severe sexual problems during their lifetimes relative to 19.0 % of women who experienced non-sexual war trauma. Women exposed to conflict-related sexual violence also reported greater posttraumatic growth, but less social acknowledgement as trauma survivors, compared to survivors of non-sexual war trauma. 

The results were consistent with emerging neurobiological research, which suggests that different traumas may be differentially associated with long-term posttraumatic sequelae in sexual assault survivors than in other survivor groups and highlights the need to treat (or better prevent) deleterious effects of conflict-related sexual violence in current worldwide crisis zones.

Comparing Sex Buyers with Men Who Do Not Buy Sex: New Data on Prostitution and Trafficking

We investigated attitudes and behaviors associated with prostitution and sexual aggression among 101 men who buy sex and 101 age-, education-, and ethnicity-matched men who did not buy sex. 

Both groups tended to accept rape myths, be aware of harms of prostitution and trafficking, express ambivalence about the nature of prostitution, and believe that jail time and public exposure are the most effective deterrents to buying sex. 

Sex buyers were more likely than men who did not buy sex to report sexual aggression and likelihood to rape. Men who bought sex scored higher on measures of impersonal sex and hostile masculinity and had less empathy for prostituted women, viewing them as intrinsically different from other women. 

When compared with non-sex-buyers, these findings indicate that men who buy sex share certain key characteristics with men at risk of committing sexual aggression as documented by research based on the leading scientific model of the characteristics of non-criminal sexually aggressive men, the Confluence Model of sexual aggression.

Time-Varying Risk Factors and Sexual Aggression Perpetration among Male College Students

Purpose
Preventing sexual aggression (SA) can be informed by determining if time-varying risk factors differentiate men who follow different sexual aggression risk trajectories.

Methods
Data are from a longitudinal study with 795 college males surveyed at the end of each of their 4 years of college in 2008–2011. Repeated measures general linear models tested if changes in risk factors corresponded with sexual aggression trajectory membership.

Results
Changes in the risk factors corresponded with SA trajectories. Men who came to college with a history of SA but decreased their perpetration likelihood during college showed concurrent decreases in sexual compulsivity, impulsivity, hostile attitudes toward women, rape supportive beliefs, perceptions of peer approval of forced sex, and perceptions of peer pressure to have sex with many different women, and smaller increases in pornography use over their college years. Conversely, men who increased levels of SA over time demonstrated larger increases in risk factors in comparison to other trajectory groups.

Conclusions
The odds that males engaged in sexual aggression corresponded with changes in key risk factors. Risk factors were not static and interventions designed to alter them may lead to changes in sexual aggression risk.

College Men’s and Women’s Respective Perceptions of Risk to Perpetrate or Experience Sexual Assault: The Role of Alcohol Use and Expectancies

The present study examines alcohol use, expectancies (i.e., beliefs about the outcomes of alcohol consumption), and college men’s (n = 127) and women’s (n = 191) respective perceptions of risk to perpetrate/experience sexual violence. Interactions between alcohol consumption and expectancies were examined. Alcohol expectancies regarding assertiveness increased women’s perceived risk for sexual intercourse via alcohol/drugs. Among women reporting high alcohol use, global expectancies were positively associated with perceived risk for sexual intercourse via alcohol/drugs. Furthermore, among women reporting low alcohol use, expectancies regarding assertiveness were positively associated with perceived risk for coerced sexual contact. Implications are discussed.

Below:  Simple slopes analysis: Women’s perceived risk to experience unwanted sexual intercourse as a result of administration of alcohol or drugs



…In light of the well-documented associations among alcohol use, expectancies, and sexual assault, the purpose of this study was to examine whether these variables were also associated with men’s and women’s perceived risk of perpetrating or experiencing various forms of sexual violence. Men’s and women’s respective perceived risk to perpetrate or experience various forms of sexual violence over a 3-month interim was examined. Furthermore, because research examining the relationship between substance use behaviors and likelihood to perpetrate sexual aggression has been primarily conducted within laboratory settings that involve exposure to violent pornography or the administration of alcohol (e.g., ; ; ), this research utilized surveys that assessed men’s self-reported likelihood to engage in sexual aggression. Women also completed behaviorally oriented assessments of perceived risk to experience various forms of victimization.

Among women, the multivariate models suggested that women’s history of sexual victimization predicted perceptions of risk to experience coerced or forced sexual contact and sexual intercourse as a result of a man’s coercion or the administration of alcohol/drugs. These findings mirror prior results suggesting women with a history of sexual victimization report they are at higher risk to experience sexual assault than women without such a history (). As  discuss, it is common for individuals who experience a negative life event to recognize they may experience the event in the future.

Multivariate analyses also indicated that higher weekly alcohol use increased women’s perceived risk to experience sexual intercourse as a result of a man’s authority or administration of alcohol/drugs. Because prior research generally does not distinguish between women’s perceived risk for different types of sexual assault, the current data extend findings suggesting women who were heavy drinkers perceived themselves at higher risk for future sexual victimization than nondrinkers (). Given the clear associations between alcohol use and sexual assault (), it seems positive that women who report a higher level of weekly alcohol use recognize they may be more likely to be targeted for a sexual assault than women reporting a lower level of weekly alcohol use. However, even when women recognize that alcohol use increases risk for sexual assault, they may not take steps to reduce their risk for sexual victimization when drinking, or take steps to reduce their alcohol use. For example,  documented that although college women acknowledge that alcohol use increases a woman’s risk for sexual victimization, they nonetheless believe they will be in control of a dating situation when intoxicated. Thus, it is important that sexual assault risk reduction programs not only teach women to recognize the situational and perpetrator characteristics associated with sexual assault, but also address ways to reduce vulnerability to potential perpetrators when choosing to drink.

Several associations between women’s expectancies when drinking and perceived risk for victimization were evidenced. First, higher expectancies regarding assertiveness when drinking were associated with increased perceived risk to experience sexual intercourse as a result of administration of alcohol/drugs. Second, among women reporting low levels of alcohol use, higher expectancies regarding assertiveness when drinking were associated with increased perceptions of risk for coerced sexual contact. While speculative, it is possible that women who expect to be assertive when drinking are aware that they are more likely to encounter men who use coercion or alcohol/drugs to obtain sexual contact or intercourse, respectively. An awareness of personal vulnerability to experience unwanted sexual advances when drinking may be especially salient among women who report low levels of alcohol use and expect to be assertive when consuming alcohol. Third, among women reporting high levels of weekly alcohol use, higher expectancies regarding global positive experiences when drinking were associated with increased perceptions of risk to experience sexual intercourse as the result of the administration of alcohol/drugs. Whereas future research is needed to explore this finding, it may be women who consume high levels of alcohol and believe that drinking leads to a good outcome recognize they will be more uninhibited when drinking, and thus potentially more at risk to be given alcohol/drugs by a man seeking to obtain sexual activity against their will.

It should be noted that four of the seven multiple regression analyses did not yield associations between alcohol expectancies and women’s perceived risk for various forms of victimization. Specifically, alcohol expectancies did not emerge as a predictor of women’s perceived risk to experience forced sexual contact or sexual intercourse, unwanted sexual contact as a result of a man’s use of authority, or coerced sexual intercourse. However, relatively few women perceived themselves at some risk to experience many of these forms of victimization. Specifically, less than 40% of women perceived themselves to be at some risk to experience forced sexual contact (34.1%), forced sexual intercourse (29.3%), coerced sexual intercourse (38.2%), or unwanted sexual contact as a result of a man’s authority (18.8%). More commonly, women perceived themselves at some risk to experience coerced sexual contact (61.3%) and unwanted sexual intercourse as a result of alcohol/drug administration (41.9%). Although speculative, it is possible that alcohol expectancies serve as a more robust predictor of women’s perceived risk to experience specific types of victimization, such as unwanted sexual contact or sexual intercourse as a result of the administration of alcohol/drugs.

It was notable that 33% of men indicated some intention to perpetrate at least one form of sexual aggression. These data are consistent with research suggesting that more than one third of men who engage in sexual aggression indicate they are at risk to do so (, ; ). Because no men indicated any risk to perpetrate forced sexual contact or intercourse, and few men reported any risk to obtain sexual contact or intercourse via authority, correlates of men’s perceived likelihood to perpetrate these forms of aggression were not examined. Instead, types of sexual aggression that men reported some perceived likelihood to perpetrate included: coerced sexual contact (26.0%) or intercourse (18.9%) and administration of alcohol/drugs to obtain sexual intercourse (7.9%). These data underscore the importance of communicating to men that using verbal pressure or alcohol as a means to engage in sexual activity constitutes sexual aggression ().
Multivariate analyses suggested that a history of sexual aggression was associated with perceived likelihood to obtain sexual contact through coercion, and obtain sexual intercourse through coercion or the administration of alcohol/drugs. Because repeat perpetration is common and a relatively small group of men commit the majority of sexual assaults (), these data underscore the importance of targeting men who recognize they are at risk to engage in sexually aggressive behavior within campus sexual assault prevention programs. Social norms programs () and bystander intervention programs () may be particularly effective in teaching men the difference between appropriate and inappropriate dating behaviors.

In light of prior research documenting differences in global positive alcohol expectancies (; ) and alcohol expectancies regarding sexuality (; ; ) in sexually aggressive and nonsexually aggressive men, it was surprising that alcohol use or alcohol expectancies were not associated with men’s perceived likelihood to perpetrate any of the forms of sexual aggression in the multivariate models. Given the relatively low rates of perpetration among the current sample (12.6%), future research examining these constructs among samples of high-risk men (i.e., men with a history of sexual aggression, men who report heavy drinking) is warranted. It is possible that assessing risk to perpetrate over a longer interim may have increased men’s reporting of perceived likelihood to perpetrate. Furthermore,  reported that men’s expectancies and consumption of alcohol acted jointly to increase men’s perceived likelihood to perpetrate sexual aggression after viewing explicit and violent media. Thus, it is possible that men’s beliefs about how alcohol will influence their behavior serves to increase intentions to engage in sexual aggression only after men have consumed alcohol. Furthermore, this study did not include an assessment of personality characteristics. However, the confluence model of sexual aggression () suggests that multiple life experiences, attitudes, and behaviors interact to increase men’s proclivity to engage in sexual aggression. Future studies may advance this area of research by including measures of men’s attitudes and belief systems. Qualitative research may also be helpful in providing a richer understanding of the intrapersonal, interpersonal, and environmental factors that increase men’s likelihood to perpetrate.

Sexual Aggression Victimization & Perpetration among Female & Male University Students in Poland

This study examined the prevalence of victimization and perpetration of sexual aggression since age 15 in a convenience sample of 565 Polish university students (356 females). 

The prevalence of sexual aggression was investigated for both males and females from the perspectives of both victims and perpetrators in relation to three coercive strategies, three different victim-perpetrator relationships, and four types of sexual acts. 

We also examined the extent to which alcohol was consumed in the context of sexually aggressive incidents. The overall self-reported victimization rate was 34.3% for females and 28.4% for males. The overall perpetration rate was 11.7% for males and 6.5% for females. The gender difference was significant only for perpetration. 

Prevalence rates of both victimization and perpetration were higher for people known to each other than for strangers. In the majority of victimization and perpetration incidents, alcohol was consumed by one or both parties involved. 

The findings are discussed in relation to the international evidence and the need for tailored risk prevention and reduction programs.

The Use of Alcohol and Condoms During Sexual Assault

Sexual assault remains an important public health issue, due to the violence involved as well as the potential for health risks such as STI transmission. Alcohol has been associated with both violent and risky sexual behavior. 

This study assessed the frequency of sexual assault perpetration, alcohol use, and condom use during sexual assault in a community sample of young heterosexual male social drinkers. Participants (N=115) completed measures of their sexual assault perpetration. 

Slightly over 50% reported sexual assault perpetration; 60% of these reported repeat perpetration. Almost one-half of perpetrators reported alcohol consumption prior to every sexual assault incident. Never having used a condom during penetrative sexually aggressive acts was reported by 41.2% of perpetrators. Alcohol use and condom non-use were positively correlated for acts of forcible rape. 

Findings provide novel information about the infrequent use of condoms during sexual assault incidents and support prior evidence of the association between alcohol and sexual assault.

Toward Identification of the Sexual Killer: A Comparison of Sexual Killers Engaging in Post-Mortem Sexual Interference & Non-Homicide Sexual Aggressors

Establishing a model of sexual assault reflecting psychosocial and behavioral characteristics of perpetrators of sexual killing and rape is necessary for development in risk assessment and intervention. Methodological variations in defining sexual killing have amalgamated serial and non-serial offenders and perpetrators with direct and indirect associations between killing and sexual arousal. 

This study defined sexual killing specifying that killing should be directly linked to sexual arousal, and sampled 48 sexual killers, operationalized to include only those engaging in post-mortem sexual interference, with one or two known female victims (non-serial), from prison service national (England and Wales) databases. These sexual killers were compared with 48 non-homicide, life or indeterminately sentenced sexual aggressors on psychological and crime scene characteristics. 

Contrary to previous research, fatal outcomes were associated with neither stranger victims nor weapon presence; sexual killing was characterized by severity of violence less so than non-fatal assault. Sexual killers more often reported problems with emotional loneliness, empathic concern, and sexual entitlement than the sexual aggressors. 

Theoretical and applied implications are discussed.

Men's Perceptions of an Acquaintance Rape: The Role of Relationship Length, Victim Resistance, and Gender Role Attitudes

Sexual aggression is a persistent and prevalent issue in the United States, which often results in a number of psychological, emotional, and physical consequences for victims. The current study examined whether the length of relationship between the victim and perpetrator, level of victim resistance, and observers' gender role attitudes play a role in observers' perceptions of an alleged sexual assault. 

Participants included 297 male college students from a public university in the Northeastern United States. Contrary to hypotheses, there were no significant effects for length of relationship on participants' attributions. Relative to no resistance, verbal and physical strategies by the victim predicted higher levels of victim credibility, perpetrator culpability, and perpetrator guilt, as well as lower levels of victim culpability and perceived victim pleasure. Endorsement of traditional adversarial sex role beliefs and hostile sexist attitudes, as opposed to egalitarian attitudes, were associated with the attribution of less credibility to the victim, perceived victim trauma, perpetrator culpability, perpetrator guilt, and shorter recommended prison sentences, as well as greater victim culpability and perceived victim pleasure. 

Laypersons' perceptions of sexual assault merit further study, as they are relevant to juror decision making and third party responses to sexual victimization (e.g., peer support for victim) and can contribute to the secondary victimization and recovery of survivors of sexual assault.

A Dangerous Boomerang: Injunctive Norms, Hostile Sexist Attitudes & Male-To-Female Sexual Aggression

Study examined the interactive effects of injunctive norm exposure and hostile and benevolent sexist attitudes on men's sexually aggressive responses during a behavioral analogue paradigm in which they interacted online with a bogus female partner. Heterosexual adult men (n = 201), recruited from an online sample, read fictional information regarding other men's approval of misogynistic, paternalistic, or egalitarian treatment of women, or non-gender-relevant control information. 

Through a media preference survey, men then learned that their female partner disliked sexual content in films, after which they had an opportunity to send her up to 120 sec' worth of either a sexually explicit or nonsexual film clip. Validating the online sexual aggression paradigm, men with a 1-year history of sexual assault exhibited more sexually aggressive responding during the film selection paradigm. 

Moreover, exposure to injunctive norm information produced a boomerang effect, such that men high in hostile sexist attitudes showed an increase in sexual aggression when confronted with paternalism and gender equality norms. Conversely, exposure to paternalism and gender equality norms suppressed the otherwise protective function of high benevolent sexism in reducing men's sexually aggressive tendencies.
