  abstract  = {From the beginning of systematic research on sexual victimization, it has been recognized that a substantial proportion of women report nonconsensual sexual experiences meeting the defining criteria of rape in response to behaviorally specific items, but do not acknowledge their experience as rape in response to broad questions about whether they have ever been raped. Recent studies suggest that rates of unacknowledged rape may be as high or even higher among men than among women. This study examined rates of unacknowledged female and male victims of rape and sexual assault by comparing responses to behaviorally specific items of the Sexual Aggression and Victimization Scale (SAV-S) with responses to broad questions using the labels of sexual assault and rape (SARA) in 593 participants (303 women) in Germany. As predicted, more women and men were classified as rape victims based on behaviorally specific items than on the basis of the broad rape item. The rates of unacknowledged rape were about 60\% for women and 75\% for men. The gender difference was not significant. Against our prediction, no significant differences in acknowledgement of sexual assault were found in relation to coercive strategy and victim-perpetrator relationship. Few cases of rape and sexual assault identified by the SARA items were missed by the behaviorally specific questions. The implications for establishing prevalence rates of rape and sexual assault and for comparing victims and nonvictims in terms of vulnerability factors and outcomes of sexual victimization are discussed.},

  abstract  = {Although sexual aggression is recognized as a serious problem worldwide, evidence on the prevalence and impact of sexual aggression is based predominantly on studies from Western countries with a Christian or non-religious majority. Little evidence is available from non-Western countries, especially from Muslim societies. The purpose of the present article was to provide a first systematic review of the studies examining the prevalence of sexual aggression in Turkey, including both victimization and perpetration reports from women and men. Additionally, differences in prevalence rates depending on relationship constellations and characteristics of victims and perpetrators were reviewed. By a two-stage literature search, 56 studies were identified for inclusion. All studies examined sexual victimization of women, only four studies included sexual victimization of men. Data on sexual aggression perpetration were extremely limited, with only two studies providing prevalence rates. Prevalence rates of sexual victimization were found to vary greatly, which may be attributed to a lack of methodological and conceptual consistency across studies. Likewise, no consistent picture was revealed for victims' or perpetrators' sociodemographic or situational characteristics associated with differences in prevalence rates. We discuss reasons for the variability in prevalence rates and outline recommendations for future research.},

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.},

Because most of the evidence on teen dating violence (TDV) synthesized in reviews comes from North American studies, this review aimed to compile evidence on prevalence rates of TDV based on studies identified for Europe only. Specifically, we considered different forms of TDV victimization and perpetration, gender differences, and its measurement. A systematic literature search of the most popular databases Ebsco and PubMed yielded a total of N = 34 studies, with most of the studies identified for Spain, and only a few studies in other European countries. In sum, the results revealed a great variability in prevalence rates across and within the European countries, a common pattern of gender differences, and a wide range of applied measures, corresponding with the evidence from the North American studies.

Little research has been conducted on the prevalence of sexual aggression in developing countries, including Chile. This article presents the first systematic review of the evidence on the prevalence of sexual aggression victimization and perpetration among women and men in Chile. Furthermore, it reports differences in prevalence rates in relation to victim and perpetrator characteristics and victim-perpetrator relationships. A total of N = 28 studies were identified by a three-stage literature search, including the screening of academic databases, publications of Chilean institutions, and reference lists. A great heterogeneity was found for prevalence rates of sexual victimization, ranging between 1.0\% and 51.9\% for women and 0.4\% and 48.0\% for men. Only four studies provided perpetration rates, which varied between 0.8\% and 26.8\% for men and 0.0\% and 16.5\% for women. No consistent evidence emerged for differences in victimization rates in relation to victims' gender, age, and education. Perpetrators were more likely to be persons known to the victim. Conceptual and methodological differences between the studies are discussed as reasons for the great variability in prevalence rates, and recommendations are provided for a more harmonized and gender-inclusive approach for future research on sexual aggression in Chile.},

All participants were asked about both victimization by, and perpetration of, sexual aggression since the age of 14 years, using the Sexual Aggression and Victimization Scale (SAV-S). Prevalence rates were established for different coercive strategies, sexual acts, and victim-perpetrator relationships. Both same-sex and opposite-sex victim-perpetrator constellations were examined. The overall victimization rate was 62.1\% for women and 37.5\% for men. The overall perpetration rate was 17.7\% for men and 9.4\% for women. Prevalence rates of both victimization and perpetration were higher for participants who had sexual contacts with both opposite-sex and same-sex partners than for participants with exclusively opposite-sex partners. Significant overlap was found between victim and perpetrator status for men and women as well as for participants with only opposite-sex and both opposite-sex and same-sex partners. A disparity between (higher) victimization and (lower) perpetration reports was found for both men and women, suggesting a general underreporting of perpetration rather than a gendered explanation in terms of social desirability or the perception of consent cues. The findings are placed in the international research literature on the prevalence of sexual aggression before and after the \#metoo campaign, and their implications for prevention efforts are discussed.},

  abstract  = {Background: Although sexual aggression is recognized as a serious issue worldwide, the current knowledge base is primarily built on evidence from Western countries, particularly the U.S. For the present doctoral research, Chile and Turkey were selected based on theoretical considerations to examine the prevalence as well as predictors of sexual aggression victimization and perpetration. The first aim of this research project was to systematically review the available evidence provided by past studies on this topic within each country. The second aim was to empirically study the prevalence of experiencing and engaging in sexual aggression since the age of consent among college students in Chile and Turkey. The third aim was to conduct cross-cultural analyses examining pathways to victimization and perpetration based on a two-wave longitudinal design. Methods: This research adopted a gender-inclusive approach by considering men and women in both victim and perpetrator roles. For the systematic reviews, multiple-stage literature searches were performed, and based on a predefined set of eligibility criteria, 28 studies in Chile and 56 studies in Turkey were identified for inclusion. A two-wave longitudinal study was conducted to examine the prevalence and predictors of sexual aggression among male and female college students in Chile and Turkey. Self-reports of victimization and perpetration were assessed with a Chilean Spanish or Turkish version of the Sexual Aggression and Victimization Scale. Two path models were conceptualized in which participants' risky sexual scripts for consensual sex, risky sexual behavior, sexual self-esteem, sexual assertiveness, and religiosity were assessed at T1 and used as predictors of sexual aggression victimization and perpetration at T2 in the following 12 months, mediated through past victimization or perpetration, respectively. The models differed in that sexual assertiveness was expected to serve different functions for victimization (refusal assertiveness negatively linked to victimization) and perpetration (initiation assertiveness positively linked to perpetration). Results: Both systematic reviews revealed that victimization was addressed by all included studies, but data on perpetration was severely limited. A great heterogeneity not only in victimization rates but also in predictors was found, which may be attributed to a lack of conceptual and methodological consistency across studies. The empirical analysis of the prevalence of sexual aggression in Chile revealed a victimization rate of 51.9\% for women and 48.0\% for men, and a perpetration rate of 26.8\% for men and 16.5\% for women. In the Turkish original data, victimization was reported by 77.6\% of women and 65.5\% of men, whereas, again, lower rates were found for perpetration, with 28.9\% of men and 14.2\% of women reporting at least one incident. The cross-cultural analyses showed, as expected, that risky sexual scripts informed risky sexual behavior, and thereby indirectly increased the likelihood of victimization and perpetration at T2 in both samples. More risky sexual scripts were also linked to lower levels of refusal assertiveness in both samples, indirectly increasing the vulnerability to victimization at T2. High sexual self-esteem decreased the probability of victimization at T2 through higher refusal assertiveness as well as through less risky sexual behavior also in both samples, whereas it increased the odds of perpetration at T2 via higher initiation assertiveness in the Turkish sample only. Furthermore, high religiosity decreased the odds of perpetration and victimization at T2 through less risky sexual scripts and less risky sexual behavior in both samples. It reduced the vulnerability to victimization through less risky sexual scripts and higher refusal assertiveness in the Chilean sample only. In the Turkish sample only, it increased the odds of perpetration and victimization through lower sexual self-esteem. Conclusions: The findings showed that sexual aggression is a widespread problem in both Chile and Turkey, contributing cross-cultural evidence to the international knowledge base and indicating the clear need for implementing policy measures and prevention strategies in each country. Based on the results of the prospective analyses, concrete implications for intervention efforts are discussed.},

Hence, the purpose of this study was to examine the prevalence and predictors of TDV among Slovenian adolescents for the first time. Using data from the SPMAD study (Study of Parental Monitoring and Adolescent Delinquency), 330 high school students were asked about physical TDV victimization and perpetration as well as about their dating history, relationship conflicts, peers' antisocial behavior, and informal social control by family and school. A substantial number of female andmale adolescents reported victimization (16.7\% of female and 12.7\% of male respondents) and perpetration (21.1\% of female and 6.0\% of male respondents). Furthermore, the results revealed that lower age at the first relationship, relationship conflicts, and school informal social control were associated with victimization, whereas being female, relationship conflicts, having antisocial peers, and family informal social control were linked to perpetration.

  abstract  = {Although many studies have shown that victims of child abuse have an increased vulnerability to revictimization in intimate relationships, the underlying mechanisms are not yet sufficiently well understood. Therefore, this study aimed at examining this relationship for both sexual and physical forms of violence as well as investigating the potential mediating role of attitudes toward sexual and physical intimate partner violence (IPV). Also, the potential moderating role of gender was explored. Sexual and physical child abuse and IPV victimization in adulthood as well as attitudes toward the respective form of IPV were assessed among 716 participants (448 female) in an online survey. The path analyses showed that child sexual abuse was positively linked to sexual IPV victimization among both women and men, whereas child physical abuse was positively associated with physical IPV victimization among women only. Furthermore, the relationship between both forms of child abuse and IPV victimization was mediated through more supportive attitudes toward the respective forms of IPV, but only among men. This study provides novel insights regarding the links between sexual and physical child abuse and revictimization in adulthood, suggesting that supporting attitudes toward IPV may be seen as vulnerability factor for revictimization. The moderating role of gender is especially discussed.},

  abstract  = {Using dating apps has become popular for many young adults worldwide, promising the chance to meet new sexual partners. Because there is evidence that using dating apps may be associated with risky sexual behavior, this study compared users and non-users concerning their sexuality-related cognitions, namely their risky sexual scripts and sexual self-esteem, as well as their risky and sexually assertive behavior. It also explored the link between dating app use and acceptance of sexual coercion. A total of 491 young heterosexual adults (295 female) participated in an online survey advertised in social media and college libraries in Germany. Results indicated that users had more risky sexual scripts and reported more risky sexual behavior than non-users. Furthermore, male dating app users had lower sexual self-esteem and higher acceptance of sexual coercion than male non-users. In both gender groups, dating app use predicted casual sexual activity via a more risky casual sex script. Gender differences, potential underlying mechanisms, and directions for future research are discussed.},

  abstract  = {Sexual aggression is a problem among college students worldwide, and a growing body of research has identified variables associated with an increased risk of victimization and perpetration. Among these, sexuality-related cognitions, such as sexual scripts, sexual self-esteem, perceived realism of pornography, and acceptance of sexual coercion, play a major role. The current experimental study aimed to show that these cognitive risk factors of sexual aggression victimization and perpetration are amenable to change, which is a critical condition for evidence-based intervention efforts. College students in Germany (N = 324) were randomly assigned to one of three groups: a treatment group designed to change participants' sexual scripts for consensual sex with regard to the role of alcohol consumption, casual sex, and ambiguous communication of sexual intentions as risk factors for sexual aggression (EG1), a treatment group designed to promote sexual self-esteem, challenge the perceived realism of pornography, and reduce the acceptance of sexual coercion (EG2), and a non-treatment control group (CG). Baseline (T1), post-experimental (T2), and follow-up (T3) measures were taken across an eight-week period. Sexual scripts contained fewer risk factors for sexual aggression in EG1 than in EG2 and CG at T3. Sexual self-esteem was enhanced in EG2 at T2 relative to the other two groups. Acceptance of sexual coercion was lower in EG2 than in EG1 and CG at T2 and T3. No effect was found for perceived realism of pornography. The findings are discussed in terms of targeting cognitive risk factors as a basis for intervention programs.},

After a review of definitions and measures of elder abuse, the findings of 20 original studies containing 26 samples from 17 countries published since 2010 are summarized. Overall prevalence rates showed a high variability across studies, ranging from 2.2\% in a study from Ireland to 43.7\% in a study from Egypt. Evidence on gender differences in the vulnerability for abuse and the predominant relationship constellations between abusers and victims did not yield a consistent picture across studies. Conceptual and methodological reasons for the variability in prevalence rates are discussed, and an outlook for future research is presented. In particular, consistent definitions and measures are needed to facilitate the comparative analysis of elder abuse in different studies and cultural contexts.},
