Do impulsivity and biological sex moderate associations between alcohol-related sexual willingness and behavior among young adults?

Abstract

This study examined three-way interactions between baseline levels of willingness to engage in alcoholrelated sexual behaviors, facets of impulsivity (i.e., urgency, lack of premeditation, and sensation seeking) and biological sex on alcohol-related sexual behaviors 6 months later. Participants were a sample of highrisk 18–25 year olds (N = 321, mean age 22.44) from a larger randomized controlled trial with eligibility criteria including engaging in unprotected sexual behavior after drinking alcohol within the past month at baseline. Results indicated females reporting high urgency and willingness levels were the most likely to engage in alcohol-related sex and to use a condom/dental dam after drinking. Males reporting low urgency levels and high sensation seeking and willingness levels engaged in more alcohol-related sex compared to females. Interventions to decrease alcohol-related sexual behavior by reducing willingness could incorporate sex-specific and impulsivity-related content, particularly related to urgency.
