“…Descriptive norms exhibit a powerful, positive association with adolescents' own self-reported alcohol use (e.g., Capaldi et al, 2009), likely due to both peer influence and homophily (i.e., the tendency for youth who use alcohol to befriend other youth who also use alcohol) (e.g., Patrick et al, 2014). Promoting prosocial friend selection and altering descriptive norms may therefore reduce risk of adolescent HED (Brooks-Russell et al, 2014;Hoeben et al, 2021;Patrick et al, 2014). Existing evidence-based interventions have been successful at delaying alcohol use age at onset (Hawkins et al, 1992), correcting overestimates of normative perceptions about alcohol use (Faggiano et al, 2010;Lewis & Neighbors, 2006), and promoting pro-social friend selection and interpersonal skills for addressing peer influences on alcohol use (Faggiano et al, 2010;Hawkins et al, 1992).…”
