Alcohol Use and Hostility Toward Women: Individual and Perceived Peer Attitudes Shape College Men's Consent Behavior.

Process-based consent conceives of sexual consent as a process whereby individuals are continuously considering and have concern for their sexual partner's willingness to continue engaging in sexual behavior without coercion. The current study used cross-sectional survey data and hierarchical linear regression to examine the independent and interactive effects of sex-related alcohol use attitudes, hostility toward women, and peer support for abuse on college men's process-based consent ( = 463; age = 19; 93% heterosexual; 64% White, non-Hispanic). Findings revealed significant main effects of all three primary study variables on process-based consent beliefs and behaviors while controlling for fraternity membership, relationship status, and sexual history. A significant three-way interaction indicated that permissive sex-related alcohol use attitudes may inhibit process-based consent among college men with higher levels of hostility toward women who also believe their peers hold rape-supportive attitudes. These findings indicate that education around consent is necessary but may not be sufficient for preventing sexual violence. Interventions developed with and delivered by peer leaders that challenge harmful peer group norms about sex-related alcohol use and the mistreatment of women may create a social environment with more favorable conditions for changing individual college men's beliefs and behaviors.
