Beliefs About Consent and Sexual Assault Perpetration in a Longitudinal Study of College Men

This study examined the mediating role of beliefs about both active and passive consent in the prospective associations between sexual assault (SA) risk factors and coercive, incapacitated, and forcible attempted/completed SA among college men. Participants were 471 college men who completed self-report surveys at the end of each of their 4 years of college. SA risk factors (risky behavior, rape-supportive beliefs and peer norms, personality traits, childhood adversity) were assessed at Wave 1, beliefs about consent were assessed at Wave 2, and perpetration was assessed at Waves 3 and 4. Multivariate regression models with bias-corrected bootstrapping assessed longitudinal mediation. SA risk factors were negatively associated with endorsement of active consent (verbal approval required) and positively associated with passive consent (assume "yes" until you hear a "no"), with strongest effects observed for coercive SA. Both types of beliefs about consent served as mediators between risk factors and perpetration. Findings suggest that prevention programs should include a focus on reducing SA risk factors, clarifying definitions of consent, and improving sexual communication.
