Evidence on the prevalence of sexual aggression among college students is primarily based on studies from Western countries. In Chile, a South American country strongly influenced by the Catholic Church, little research on sexual aggression among college students is available. Therefore, the purpose of the present study was to examine the prevalence of sexual aggression victimization and perpetration since the age of 14 (the legal age of consent) in a sample of male and female students aged between 18 and 29 years from five Chilean universities ( N = 1135), to consider possible gender differences, and to study the extent to which alcohol was involved in the reported incidents of perpetration and victimization. Sexual aggression victimization and perpetration was measured with a Chilean Spanish version of the Sexual Aggression and Victimization Scale (SAV-S), which includes three coercive strategies (use or threat of physical force, exploitation of an incapacitated state, and verbal pressure), three victim-perpetrator constellations (current or former partners, friends/acquaintances, and strangers), and four sexual acts (sexual touch, attempted sexual intercourse, completed sexual intercourse, and other sexual acts, such as oral sex). Overall, 51.9% of women and 48.0% of men reported at least one incident of sexual victimization, and 26.8% of men and 16.5% of women reported at least one incident of sexual aggression perpetration since the age of 14. For victimization, only few gender differences were found, but significantly more men than women reported sexual aggression perpetration. A large proportion of perpetrators also reported victimization experiences. Regarding victim-perpetrator relationship, sexual aggression victimization and perpetration were more common between persons who knew each other than between strangers. Alcohol use by the perpetrator, victim, or both was involved in many incidents of sexual aggression victimization and perpetration, particularly among strangers. The present data are the first to provide a systematic and detailed picture of sexual aggression among college students in Chile, including victimization and perpetration reports by both men and women and confirming the critical role of alcohol established in past research from Western countries.

Using both cross-sectional and prospective analyses, this study examined vulnerability factors for sexual victimization in 541 female and male Brazilian college students, of whom a subgroup of 250 took part in two measurements 6 months apart. Risk factors for sexual victimization (alcohol consumption, casual sex, and ambiguous communication) in participants' cognitive scripts for consensual sex were linked to sexual victimization via their translation into risky sexual behavior. Pornography use was indirectly linked to sexual victimization through its influence on risky sexual scripts and sexual behavior. Child sexual abuse predicted sexual victimization in the cross-sectional analysis, and victimization since age 14 predicted revictimization in the six months covered by the prospective period. Few gender differences were found. This study is the first prospective investigation of vulnerability factors for sexual victimization in Brazil, and similarities to evidence from North America are discussed.

Individual differences in justice sensitivity and rejection sensitivity have been linked to differences in aggressive behavior in adults. However, there is little research studying this association in children and adolescents and considering the two constructs in combination. We assessed justice sensitivity from the victim, observer, and perpetrator perspective as well as anxious and angry rejection sensitivity and linked both constructs to different forms (physical, relational), and functions (proactive, reactive) of self-reported aggression and to teacher- and parent-rated aggression in N = 1,489 9- to 19-year olds in Germany. Victim sensitivity and both angry and anxious rejection sensitivity showed positive correlations with all forms and functions of aggression. Angry rejection sensitivity also correlated positively with teacher-rated aggression. Perpetrator sensitivity was negatively correlated with all aggression measures, and observer sensitivity also correlated negatively with all aggression measures except for a positive correlation with reactive aggression. Path models considering the sensitivity facets in combination and controlling for age and gender showed that higher victim justice sensitivity predicted higher aggression on all measures. Higher perpetrator sensitivity predicted lower physical, relational, proactive, and reactive aggression. Higher observer sensitivity predicted lower teacher-rated aggression. Angry rejection sensitivity predicted higher proactive and reactive aggression, whereas anxious rejection sensitivity did not make an additional contribution to the prediction of aggression. The findings are discussed in terms of social information processing models of aggression in childhood and adolescence., (© 2014 Wiley Periodicals, Inc.)

In a four-wave longitudinal study with N = 1,321 adolescents in Germany, we examined the impact of class-level normative beliefs about aggression on aggressive norms and behavior at the individual level over the course of 3 years. At each data wave, participants indicated their normative acceptance of aggressive behavior and provided self-reports of physical and relational aggression. Multilevel analyses revealed significant cross-level interactions between class-level and individual-level normative beliefs at T1 on individual differences in physical aggression at T2, and the indirect interactive effects were significant up to T4. Normative approval of aggression at the class level, especially girls' normative beliefs, defined the boundary conditions for the expression of individual differences in aggressive norms and their impact on physically and relationally aggressive behavior for both girls and boys. The findings demonstrate the moderating effect of social norms on the pathways from individual normative beliefs to aggressive behavior in adolescence., (© 2015 by the Society for Personality and Social Psychology, Inc.)

An observational measure of anger regulation in middle childhood was developed that facilitated the in situ assessment of five maladaptive regulation strategies in response to an anger-eliciting task. 599 children aged 6-10 years (M = 8.12, SD = 0.92) participated in the study. Construct validity of the measure was examined through correlations with parent- and self-reports of anger regulation and anger reactivity. Criterion validity was established through links with teacher-rated aggression and social rejection measured by parent-, teacher-, and self-reports. The observational measure correlated significantly with parent- and self-reports of anger reactivity, whereas it was unrelated to parent- and self-reports of anger regulation. It also made a unique contribution to predicting aggression and social rejection.

Data are presented on young people's sexual victimisation and perpetration from 10 European countries (Austria, Belgium, Cyprus, Greece, Lithuania, the Netherlands, Poland, Portugal, Slovakia and Spain) using a shared measurement tool (N = 3480 participants, aged between 18 and 27 years). Between 19.7 and 52.2% of female and between 10.1 and 55.8% of male respondents reported having experienced at least one incident of sexual victimisation since the age of consent. In two countries, victimisation rates were significantly higher for men than for women. Between 5.5 and 48.7% of male and 2.6 and 14.8% of female participants reported having engaged in a least one act of sexual aggression perpetration, with higher rates for men than for women in all countries. Victimisation rates correlated negatively with sexual assertiveness and positively with alcohol use in sexual encounters. Perpetration rates correlated positively with attitudes condoning physical dating violence and with alcohol use in men, and negatively with sexual assertiveness in women. At the country level, lower gender equality in economic power and in the work domain was related to higher male perpetration rates. Lower gender equality in political power and higher sexual assertiveness in women relative to men were linked to higher male victimisation rates.

In a longitudinal study with N = 1,854 adolescents from Germany, we investigated patterns of change and gender differences in physical and relational aggression in relation to normative beliefs about these two forms of aggression. Participants, whose mean age was 13 years at T1, completed self-report measures of physically and relationally aggressive behavior and indicated their normative approval of both forms of aggression at four data waves separated by 12-month intervals. Boys scored higher than did girls on both forms of aggression, but the gender difference was more pronounced for physical aggression. Physical aggression decreased and relational aggression increased over the four data waves in both gender groups. The normative acceptance of both forms of aggression decreased over time, with a greater decrease for the approval of physical aggression. In both gender groups, normative approval of relational aggression prospectively predicted relational aggression across all data waves, and the normative approval of physical aggression predicted physically aggressive behavior at the second and third data waves. A reciprocal reinforcement of aggressive norms and behavior was found for both forms of aggression. The findings are discussed as supporting a social information processing perspective on developmental patterns of change in physical and relational aggression in adolescence.

Despite recent growth of research on the effects of prosocial media, processes underlying these effects are not well understood. Two studies explored theoretically relevant mediators and moderators of the effects of prosocial media on helping. Study 1 examined associations among prosocial- and violent-media use, empathy, and helping in samples from seven countries. Prosocial-media use was positively associated with helping. This effect was mediated by empathy and was similar across cultures. Study 2 explored longitudinal relations among prosocial-video-game use, violent-video-game use, empathy, and helping in a large sample of Singaporean children and adolescents measured three times across 2 years. Path analyses showed significant longitudinal effects of prosocial- and violent-video-game use on prosocial behavior through empathy. Latent-growth-curve modeling for the 2-year period revealed that change in video-game use significantly affected change in helping, and that this relationship was mediated by change in empathy.

This study examined the prevalence of sexual aggression and victimization in a large convenience sample of N = 2,149 first-year college students from different universities in Germany. Participants were asked about both victimization by, and perpetration of, sexual aggression since the age of 14. Both same-sex and heterosexual victim-perpetrator constellations were examined. Prevalence rates were established for different victim-perpetrator relationships (partners, acquaintances, strangers) and for incidents involving alcohol consumption by one or both partners. The overall perpetration rate was 13.2%, for men and 7.6% for women. The overall victimization rate was 35.9% for women and 19.4% for men. A disparity between victimization and perpetration reports was found for both men and women. Perpetration and victimization rates were highest among participants who had sexual contacts with both opposite-sex and same-sex partners. Sexual aggression and victimization rates were higher between current or former partners and acquaintances than between strangers. Alcohol consumption by one or both partners was involved in almost 75% of all victimization and almost 70% of all perpetration incidents. The findings portray a comprehensive picture of the scale of sexual aggression and victimization in college students with different sexual lifestyles., (© 2013 Wiley Periodicals, Inc.)

Despite the increased attention devoted to sexual aggression among college students in the international research literature, Brazil has no systematic studies on the prevalence of sexual aggression in college populations. The present research measured the prevalence of sexual aggression and victimization since age 14 among 742 first-year college students in Brazil (411 women). A Portuguese version of the Short Form of the Sexual Experiences Survey (Koss et al., 2007 ) was administered to collect information from men and women as both victims and perpetrators of sexual aggression. The overall prevalence rate of victimization was 27% among men and 29% among women. Except for sexual coercion and attempted sexual coercion, there were no significant gender differences in victimization rates concerning nonconsensual sexual acts and aggressive strategies. In contrast, perpetration rates were significantly higher among men (33.7%) than among women (3%). The findings challenge societal beliefs that men are unlikely to be sexually coerced. Explanations are proposed for the disparity between male victimization and female perpetration rates based on traditional gender roles in Brazil.

Two studies investigated the effects of information related to rape myths on Spanish college students' perceptions of sexual assault. In Study 1, 92 participants read a vignette about a nonconsensual sexual encounter and rated whether it was a sexual assault and how much the woman was to blame. In the scenario, the man either used physical force or offered alcohol to the woman to overcome her resistance. Rape myth acceptance (RMA) was measured as an individual difference variable. Participants were more convinced that the incident was a sexual assault and blamed the woman less when the man had used force rather than offering her alcohol. In Study 2, 164 college students read a scenario in which the woman rejected a man's sexual advances after having either accepted or turned down his offer of alcohol. In addition, the woman was either portrayed as being sexually attracted to him or there was no mention of her sexual interest. Participants' RMA was again included. High RMA participants blamed the victim more than low RMA participants and were less certain that the incident was a sexual assault, especially when the victim had accepted alcohol and was described as being sexually attracted to the man. The findings are discussed in terms of their implications for the prevention and legal prosecution of sexual assault.

Several longitudinal studies and meta-analytic reviews have demonstrated that exposure to violent media is linked to aggression over time. However, evidence on effective interventions to reduce the use of violent media and promote critical viewing skills is limited. The current study examined the efficacy of an intervention designed to reduce the use of media violence and aggression in adolescence, covering a total period of about 12 months. A sample of 683 7th and 8th graders in Germany (50.1% girls) were assigned to two conditions: a 5-week intervention and a no-intervention control group. Measures of exposure to media violence and aggressive behavior were obtained about 3 months prior to the intervention (T1) and about 7 months post-intervention (T2). The intervention group showed a significantly larger decrease in the use of violent media from T1 to T2 than the control group. Participants in the intervention group also scored significantly lower on self-reported aggressive behavior (physical aggression and relational aggression) at T2 than those in the control group, but the effect was limited to those with high levels of initial aggression. This effect was mediated by an intervention-induced decrease in the normative acceptance of aggression. No gender differences in program efficacy were found. The results show that a 5-week school-based intervention can produce changes in the use of media violence, aggressive norms, and behaviors sustained over several months.

Research in legal decision making has demonstrated the tendency to blame the victim and exonerate the perpetrator of sexual assault. This study examined the hypothesis of a special leniency bias in rape cases by comparing them to cases of robbery. N = 288 participants received descriptions of rape and robbery of a female victim by a male perpetrator and made ratings of victim and perpetrator blame. Case scenarios varied with respect to the prior relationship (strangers, acquaintances, ex-partners) and coercive strategy (force vs. exploiting victim intoxication). More blame was attributed to the victim and less blame was attributed to the perpetrator for rape than for robbery. Information about a prior relationship between victim and perpetrator increased ratings of victim blame and decreased perceptions of perpetrator blame in the rape cases, but not in the robbery cases. The findings support the notion of a special leniency bias in sexual assault cases.

The relations between adolescents' habitual usage of media violence and their tendency to engage in aggressive and prosocial behavior in a school setting were examined in a cross-sectional study with 1688 7th and 8th graders in Germany who completed measures of violent media exposure and normative acceptance of aggression. For each participant, ratings of prosocial and aggressive behavior were obtained from their class teacher. Media violence exposure was a unique predictor of teacher-rated aggression even when relevant covariates were considered, and it predicted prosocial behavior over and above gender. Path analyses confirmed a direct positive link from media violence usage to teacher-rated aggression for girls and boys, but no direct negative link to prosocial behavior was found. Indirect pathways were identified to higher aggressive and lower prosocial behavior via the acceptance of aggression as normative. Although there were significant gender differences in media violence exposure, aggression, and prosocial behavior, similar path models were identified for boys and girls., (Copyright © 2010 The Association for Professionals in Services for Adolescents.

This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content.

Repression and sensitization as situational modes of coping with anxiety were examined as predictors of trait measures of cognitive avoidance and vigilance. In this study, 303 undergraduates saw a violent film clip to elicit anxiety. Increases in skin conductance level (SCL) and state anxiety (STA) from baseline were measured to identify repressors (high SCL, low STA) and contrast them with sensitizers (low SCL, high STA) and genuinely low anxious individuals (low SCL, low STA). State anger was also recorded. Trait measures of vigilance and cognitive avoidance were collected 2 weeks earlier. Significant SCL × STA interactions indicated that repressors scored higher on cognitive avoidance and lower on vigilance compared to sensitizers and low anxious participants. Repressors were less likely than sensitizers to report gaze avoidance during the clip. The anger by SCL interaction was nonsignificant, suggesting that repressors and sensitizers differ specifically in the processing of anxiety rather than negative affect in general., (© 2011 The Authors.

The relationship between exposure to violent electronic games and aggressive cognitions and behavior was examined in a longitudinal study. A total of 295 German adolescents completed the measures of violent video game usage, endorsement of aggressive norms, hostile attribution bias, and physical as well as indirect/relational aggression cross-sectionally, and a subsample of N=143 was measured again 30 months later. Cross-sectional results at T1 showed a direct relationship between violent game usage and aggressive norms, and an indirect link to hostile attribution bias through aggressive norms. In combination, exposure to game violence, normative beliefs, and hostile attribution bias predicted physical and indirect/relational aggression. Longitudinal analyses using path analysis showed that violence exposure at T1 predicted physical (but not indirect/relational) aggression 30 months later, whereas aggression at T1 was unrelated to later video game use. Exposure to violent games at T1 influenced physical (but not indirect/relational) aggression at T2 via an increase of aggressive norms and hostile attribution bias. The findings are discussed in relation to social-cognitive explanations of long-term effects of media violence on aggression., (Copyright 2008 Wiley-Liss, Inc.)

The characteristic features of adolescents' sexual scripts were explored in 400 tenth and eleventh graders from Berlin, Germany. Participants rated the prototypical elements of three scripts for heterosexual interactions: (1) the prototypical script for the first consensual sexual intercourse with a new partner as pertaining to adolescents in general (general script); (2) the prototypical script for the first consensual sexual intercourse with a new partner as pertaining to themselves personally (individual script); and (3) the script for a nonconsensual sexual intercourse (rape script). Compared with the general script for the age group as a whole, the individual script contained fewer risk elements related to sexual aggression and portrayed more positive consequences of the sexual interaction. Few gender differences were found, and coital experience did not affect sexual scripts. The rape script was found to be close to the "real rape stereotype." The findings are discussed with respect to the role of sexual scripts as guidelines for behavior, particularly in terms of their significance for the prediction of sexual aggression.

Two longitudinal studies examined German adolescents' sexual scripts in relation to the normative acceptance of sexual aggression, the behavioral enactment of risk factors, and the experience of sexual aggression/victimization. Study 1 comprised a sample of 283 10th and 11th grade high school students who completed measures of sexual scripts, normative acceptance of risk elements associated with sexual aggression, behavioral risk-taking, and normative acceptance of sexual aggression in relationships twice with a nine-month interval. General and individual scripts differed significantly in terms of the prevalence of risk elements, with individual scripts containing fewer risk elements. Normative acceptance of risk elements was linked to the enactment of risky behavior in sexual interactions and also to the normative acceptance of sexual aggression, both concurrently and over time. In Study 2, 232 12th and 13th grade students completed measures of sexual scripts and of sexual aggression or sexual victimization. Higher risk scores in the individual scripts were predictive of sexual aggression among boys and sexual victimization among girls. The findings were discussed in terms of the significance of sexual scripts as guidelines for sexual behavior.

The extent to which international students and academics feel discriminated against in the host country was explored in three samples from two countries: students in Germany (N = 161), students in the UK (N = 139), and academics in Germany (N = 79). Respondents completed a measure of perceived discrimination of increasing severity, comprising antilocution (verbal derogation), avoidance, behavioural discrimination, and physical assault. Physical discernibility as foreigner, quality of private contacts with host nationals, and language proficiency were explored as predictors of perceived discrimination. Across the three samples, respondents who were identifiable as foreigners by their appearance reported more discrimination. Positive contacts with host nationals were associated with lower levels of perceived discrimination. Language proficiency predicted perceived antilocution in the two German samples. All samples perceived their personal level of discrimination to be lower than that of their respective in-groups (international students/academics), but the tendency was moderated by visibility and contact quality.

Individual differences in women's avoidant and vigilant style in coping with the threat of rape were explored in four studies. In the first study, 97 women read a rape scenario and completed measures of cognitive vigilance and avoidance. They also provided ratings of fear of rape and anticipated coping problems in case of sexual assault. Vigilance was associated with significantly higher levels of fear of rape and anticipation of more severe coping problems. No effects were found for cognitive avoidance. Study 2 replicated these findings with a sample of 275 women. In addition, it showed that high vigilance was associated with significantly more rape-preventive behaviors. Study 3, including 172 women, was an online study on the effect of cognitive coping style on fear of rape, anticipated coping problems, and two behavioral measures of rape avoidance. High vigilance was related to higher levels of fear of rape, anticipation of more severe coping problems, and more rape-preventive behaviors. Finally, Study 4 (N=210) showed that individual differences in cognitive coping style affected rape-related affect and behavior in the absence of a rape scenario, underlining the chronic salience of the threat of rape for women. Vigilance was positively related to fear of rape, rape-avoidance behavior, and anticipated coping problems. In contrast, a negative relationship was found between cognitive avoidance and fear of rape, rape-avoidance strategies, and anticipated coping problems. Across the four studies, no evidence was found for an interactive effect of cognitive avoidance and vigilance, as suggested by the construct of repression versus sensitization. The findings are discussed in the light of previous research on repression-sensitization in coping with threatening information.

An experimental evaluation of a safer sex promotion leaflet was undertaken to assess its capacity to change antecedent cognitions of condom use. The leaflet was identified in a previous study as addressing research-based cognitive antecedents of condom use. A pre-post-test experimental study including three conditions was conducted: (a) presentation of the leaflet; (b) presentation of the leaflet plus incentive for systematic processing; (c) no-leaflet control. The leaflet was evaluated in terms of its capacity to change eight cognitive correlates of condom use identified in a recent meta-analysis. The sample consisted of 230 tenth-grade students. Following baseline assessments, leaflet-induced change was measured immediately following the intervention and at a follow up 4 weeks post-intervention. The target leaflet alone did not result in significant changes in the cognitive antecedents of condom use compared with the control condition. However, in combination with an incentive for systematic processing, the target leaflet had a greater impact on cognitive antecedents than the no-leaflet control condition. The findings are discussed with regard to the development and evaluation of research-based health-promotion materials.

The relationship was examined between exposure to and preference for violent electronic games and aggressive norms as well as hostile attributional style. Following a pilot study to sample widely used electronic games varying in violent content, 231 eighth-grade adolescents in Germany reported their use of and attraction to violent electronic games. They also completed measures of hostile attributional style and endorsement of aggressive norms. There were significant gender differences in usage and attraction to violent electronic games, with boys scoring higher than girls. Significant relationships were found between attraction to violent electronic games and the acceptance of norms condoning physical aggression. Violent electronic games were linked indirectly to hostile attributional style through aggressive norms. The findings are discussed with respect to North American research on the aggression-enhancing effect of violent electronic games.

Two studies examined the prevalence and emotional impact of men's nonconsensual sexual interactions with women. The first study included a sample of 247 heterosexual men with a mean age of 18.3 years. The second study was a replication with a sample of 153 heterosexual men with a mean age of 22.3 years. All respondents completed a measure of nonconsensual sexual interactions including the use of three aggressive strategies (physical force, exploitation of the man's incapacitated state, and verbal pressure) and three forms of unwanted sexual contact (kissing/petting, sexual intercourse, and oral sex). In addition, the relationship to the female initiator was explored. For each type of nonconsensual sexual interaction, respondents indicated the affective impact of the experience. In Study 1, 25.1% of respondents reported at least one incident of nonconsensual sex with a woman and 23.9% reported attempts by women to make them engage in nonconsensual sexual activity. In Study 2, the overall prevalence rate for completed nonconsensual sexual interactions was 30.1%, and 23.5% of the men reported attempts at making them engage in nonconsensual sex. In both samples, exploiting the man's inability to offer resistance was the most frequently reported aggressive strategy. Kissing/petting was the most frequently reported unwanted sexual activity, followed by sexual intercourse and oral sex. Prevalence rates were higher for nonconsensual sex with an (ex-)partner or friend than for nonconsensual sex with an unknown women. Ratings of affective impact revealed that men rated their nonconsensual experiences as moderately upsetting. The findings are discussed in the light of previous studies on men's unwanted sexual experiences and the extant literature on women's nonconsensual sexual interactions with men.

Objective: To categorize and quantify the content of publicly available safer sex promotion leaflets in the UK and Germany and to assess the extent to which this content corresponds to the cognitive and behavioural correlates of condom use identified by theory-based research., Methods: A content analysis using a 45 category coding manual was undertaken. The manual included 20 'correlate-representative' categories identifying text promoting the strongest cognitive and behavioural correlates of condom use., Results: Overall inter-coder reliability was high. Few content differences were observed between the German and UK samples. Leaflets from both countries highlighted information on how people become infected with HIV and advice to contact health care professionals. Few mentioned delaying or abstaining from sexual intercourse. Only 25% of leaflets included text that referred to more than 10 of the 20 correlate-representative categories. Moreover, using one standard deviation above the mean as an indication of frequent inclusion, two-thirds of leafets failed to target frequently more than two of the 20 correlate-representative categories., Conclusions: Some safer sex promotion leaflets frequently promote the strongest cognitive and behavioural correlates of condom use. In general, however, the recommendations of researchers investigating psychological correlates of condom use have not shaped the content of safer sex promotion leaflets.
