Participants ( n = 520) in a study of two on-campus peer-led sexual assault prevention programs focused on bystander intervention and risk reduction were assessed. This study focused on myth reduction, as well as self-defense self-efficacy. Demographics allowed for within-group comparisons along gender and race. Among men who attended Bro Code, Black men had significantly lower sexual assault myth adherence on many rape myths than the control group, not true of white men. Those women who attended Girls Night Out (GNO) had significantly lower sexual assault myth adherence than the control group. While greater reductions in myth adherence were seen in white women than among Black women, Black women had significantly lower overall sexual assault myth adherence (in both control and sample). As a side note, we found that women who attended GNO had lower general intimate partner violence myth acceptance in addition to lower sexual assault myth acceptance, with some variation on individual myths. Finally, those women who attended self-defense training were significantly more likely to endorse self-defense self-efficacy. Results were then explored through the lens of cultural, gender, intersectional, and community-based contexts. Future research needs and implications are discussed.
