Objective: This study explored the relation between interest and membership in a fraternity and acceptance of sexual violence (e.g., rape myth acceptance, proclivity to perpetrate sexual aggression) among first year college men. Participants: A total of 315 men were surveyed before their first year of college (June-August 2010) and again at 4 time points over the next year. Methods: Participants responded to measures of rape myth acceptance and proclivity to perpetrate sexual aggression. Results: Interested members scored higher on proclivity to perpetrate sexual aggression and some rape myths than noninterested nonmembers; interested nonmembers scored in between the 2 groups. Conclusions: Results highlight the importance of considering both fraternity membership and interest in joining a fraternity, as well as examining individual rape myths, in studies of fraternity membership and sexual violence.
