Sexual consent promotion and bystander interventions are dominant approaches to address sexual assault on college campuses. Consent promotion initiatives emphasizes clear and explicit consent communication (affirmative consent) and bystander interventions promote third-party interference to prevent potential sexual assaults. Despite the popularity of these models, little is known about the impacts of alcohol consumption on people’s ability consent to sex and ability to accurately assess their friends’ intoxication level. The purpose of this study was to examine the extent that alcohol consumption effected participants’ perceptions of their own and their friend’s ability to consent to sex. We interviewed 160 young adult bargoers in dyads about their own and their friends’ alcohol consumption, intoxication symptoms, and ability to consent. Participants reported consuming a mean of 4.97 drinks, rated themselves as at the legal limit for driving, reported one intoxication symptom, and had a blood alcohol concentration (BAC) just over .08. However, few thought they or their friend had diminished cognitive function. Accordingly, 93% indicated they could consent and 87% indicated their friend could consent. Number of drinks people reported consuming, self-reported intoxication levels and symptoms, and BACs were not significantly related to participants’ perceptions of their own or their friends’ ability to consent to sex. Finally, those in man–man pairs were significantly more likely than those in woman–woman pairs to indicate they would allow their friend to have sex if approached by an interested party. Implications for sexual assault prevention initiatives, particularly consent-promotion and bystander programming, will be discussed.
