A recent review conducted a meta-analysis to summarize the effectiveness of single-session brief interventions for heavy-drinking college students. The meta-analysis combined results from 73 studies to first determine overall effectiveness of single-session brief interventions, and second, to evaluate under what conditions said interventions were effective. Included studies involved undergraduate participants (under 25yo) that engaged in past month heavy drinking, defined as consuming more than two drinks per day or four drinks per sitting. Meta-analysis revealed a 0.18 standard deviation difference between heavy-drinking college students that participated in a single-session brief intervention compared with control participants. According to the literature, this translates to a 7 percentage point difference, or heavy-drinking college students consuming roughly 0.37 fewer drinks/week than control participants one month following participation in a single-session brief intervention. Further analyses revealed that studies applying Motivational Enhancement Therapy (MET)/Motivational Interviewing (MI) intervention techniques reported larger effects than studies using Psychoeducational Therapy (PET). Take Away: This review suggests that single-session brief interventions may only modestly reduce alcohol consumption by heavy-drinking college students. In addition, studies using MET/MI techniques reported more positive effects, suggesting personalized, counseling-oriented approaches may improve the effectiveness of these types of intervention sessions.
