[Internet-based alcohol interventions for college students: systematic reviewIntervenciones por Internet para reducir el consumo de alcohol de los estudiantes universitarios: revisión sistemática].

Objective: To identify the main modalities of Internet-based interventions to limit alcohol use among university students, and to describe the effects of these interventions on alcohol use and related consequences.
Methods: A systematic review of PubMed, PsycINFO, and SciELO was performed using as search terms "alcohol drinking AND Internet," without date or language restrictions. Inclusion criteria were randomized controlled trial design, focus on college students and on Internet-based interventions, and evaluating the effects of the intervention on alcohol use or alcohol-related consequences.
Results: Thirty-six articles were analyzed. Two main intervention modalities were identified: personalized normative feedback (PNF, n=28) and multicomponent interventions (n=8). Twelve studies with PNF reported reductions in alcohol use 3 months after the intervention. Multicomponent interventions reduced alcohol use and related consequences; most studies focused on the website AlcoholEdu, which reduced alcohol consumption and the consequences of alcohol use 6 months after the intervention.
Conclusions: FNP and the AlcoholEdu website, the most frequently evaluated interventions among the selected studies, were effective in reducing alcohol use in university students. These strategies are an alternative to increase the access of university students to interventions aimed at limiting alcohol use.
