AbstractObjective: The purpose of this randomized controlled study was to examine the efficacy of a brief, web-based personalized feedback intervention (the eCHECKUP TO GO) on alcohol use and alcohol-related consequences among high school seniors. Method: Participants (N = 221) were high school seniors randomized by class period to either a brief, web-based personalized feedback intervention (the eCHECKUP TO GO) or an assessment-only control group. Participants completed online surveys at baseline and at a 6-week follow-up. Results: Students participating in the eCHECKUP TO GO intervention reported a significant reduction in weekly drinking quantity, peak drinking quantity, and frequency of drinking to intoxication relative to those in the control group. Intervention effects were moderated by high-risk status (one or more episodes of heavy episodic drinking in the past 2 weeks reported at baseline) such that intervention effects were significant for high-risk students only. Results for alcohol-related consequences were not significant. Conclusions: Providing a brief, web-based personalized feedback intervention in the school setting is a promising approach for reducing problem alcohol use among high school seniors who report recent heavy episodic drinking.Keywords: alcohol, web-based intervention, personalized feedback, high school seniors Alcohol use in high school is associated with multiple alcohol-related consequences including poor school performance, being a victim of dating violence, attempting suicide, use of other substances, and negative interpersonal interactions (Arata et al., 2003; Miller et al., 2007). Among adolescents aged 12-18, alcohol use is also associated with impaired neuropsychological functioning including deficits in verbal memory, visuospatial ability, and psychomotor speed (Hanson et al., 2011; Nguyen-Louie et al., 2015). Research also indicates that risky patterns of drinking established in high school (i.e., prepartying and playing drinking games) are predictive of both heavy drinking and alcohol-related consequences in college (Kenney et al., 2010). For these reasons, it is imperative to identify efficacious interventions for high school students to disrupt patterns of heavy drinking and the associated negative consequences both during high school and in later adulthood.This is an author-produced, peer-reviewed version of this article.
