Sexual aggression among Brazilian college students: prevalence of victimization and perpetration in men and women.

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.
