Dragan, AndreaIn the U.S., approximately 1 out of every 5 women reported a completed or attempted sexual assault in their lifetime, with women ages 18-24 being at significantly higher risk for assault. While sexual assault affects all genders, the majority of sexual assaults on campuses involve men assaulting women. Using a convenience sample of undergraduate men (n=59), this study investigated how hypermasculinity affects undergraduate male’s perceptions of sexual assault, consent, hook-up culture, and rape myth acceptance (RMA) using six validated inventories. Hypermasculinity was significantly associated with RMA (p = .001), and sexual consent attitudes and behaviors, such as a lack of perceived behavioral control (p= .004) and positive attitudes toward consent (p= .001). A significant relationship between hypermasculinity and motivations for participation in hook-up culture was also detected. These findings can inform universities how to utilize their limited resources to provide education to improve the prevalence of sexual assault.enTHE IMPACT OF HYPERMASCULINITY ON UNDERGRADUATE MEN’S PERCEPTIONS OF SEXUAL ASSAULT AND CONSENTThesisPublic healthHypermasculinityRape Myth AcceptanceSexual AssaultSexual Consent
