N2  - PURPOSE: To determine if peer risk (having friends who drink or approve of drinking) modifies the effects of a computer-facilitated screening and provider brief advice (cSBA) intervention on adolescent alcohol use. METHODS: We assessed the intervention effect using logistic regression modeling with generalized estimating equations on a sample of 2,092 adolescents. Effect modification by peer risk was analyzed separately for alcohol initiation (drinking at follow-up in baseline nondrinkers) and cessation (no drinking at follow-up in baseline drinkers) by testing an interaction term (treatment condition by peer risk). Interpretation of the interaction effect was further clarified by subsequent stratification by peer risk. RESULTS: The intervention effect on alcohol cessation was significantly greater among those with peer risk (adjusted relative risk ratios; risk 1.44, 1.18-1.76 vs. no risk .98, .41-2.36) at 3 months' follow-up. There was no such finding for alcohol initiation. CONCLUSIONS: Alcohol screening and brief provider counseling may differentially benefit adolescent drinkers with drinking friends.<p />  <p>Language: en</p>
