Effectiveness of a web-based screening and fully automated brief motivational intervention for adolescent substance use: A randomized controlled trial

Original language description

Mid-to-late adolescence is a critical period for initiation of alcohol and drug problems, which can be reduced by targeted brief motivational interventions. This study evaluated the effectiveness of a targeted and fully automated Web-based brief motivational intervention with no face-to-face components on substance use among adolescents screened for at-risk substance use in four European countries. In an open-access, purely Web-based randomized controlled trial, a convenience sample of adolescents aged 16-18 years was recruited using online and offline methods and screened online for at-risk substance use using the CRAFFT screening instrument. Primary outcome was differences in past month drinking measured by a self-reported AUDIT-C-based index score for drinking frequency, quantity, and frequency of binge drinking with measures collected online at baseline and after 3 months. Secondary outcomes were the AUDIT-C-based separate drinking indicators, illegal drug use, and polydrug use. In total, 2673 adolescents were screened and 1449 participants were randomized to the intervention or control group. After 3 months, 211 adolescents provided follow-up data. Compared to the control group, results from linear mixed models revealed significant reductions in self-reported past-month drinking in favor of the intervention group in the non-imputed (P=.010). Secondary analyses revealed a significant effect on drinking frequency (P=.037) and frequency of binge drinking (P=.044) in the non-imputation-based analyses and drinking quantity (P=.021) when missing data were imputed. Analyses for illegal drug use and polydrug use revealed no significant differences between the study groups (Ps>.05). Web-based format can be effective to reduce drinking and lessen existing substance use service barriers for at-risk drinking European adolescents.
