This study examined rape myth acceptance among 727 university students from 21 U.S. institutions with the updated Illinois Rape Myth Acceptance scale. Findings showed sorority members rejected rape myths at greater rates than non-sorority members, but fraternity members were similar to non-fraternity members. Higher rape myth acceptance was associated with males, younger ages, lower GPAs, greater religiosity, greater alcohol consumption, and not knowing a victim of a sexual assault. Research and policy implications are discussed.
