Computer-Facilitated Screening and Brief Advice to Reduce Adolescents' Heavy Episodic Drinking: A Study in Two Countries

Abstract

Purpose: A computer-facilitated screening and brief advice (cSBA) intervention was previously shown to reduce drinking among U.S. adolescents but not among Czech youth. The purpose of this study was to assess cSBA effect on heavy episodic drinking (HED).

Methods: Participants were 12- to 18-year-olds at nine U.S. primary care offices (N = 2,096) and 10 Czech pediatrician-generalist offices (N = 589) who completed measurements only during an 18-month treatment-as-usual (TAU) phase. We then initiated the cSBA protocol for all participants and recruited the 18-month cSBA phase. Generalized Estimating Equations logistic regression compared past-90-day HED for cSBA versus TAU at 3- and 12-months, controlling for baseline HED and other covariates.

Results: Baseline past-90-day HED rates were 11% for U.S. and 28% for Czech youth. At 3 months, among Czech baseline non-HED, the adjusted relative risk ratio for cSBA versus TAU was .52 (95% confidence interval .29, .92). The effect dissipated by 12 months.

Conclusions: cSBA shows promise for short-term prevention of adolescent HED.
