The effectiveness of E-interventions to reduce alcohol consumption in college and university students

A meta analysis was conducted to evaluate the effectiveness and moderators of E-Interventions versus assessment only controls in the reduction of alcoholic drinks per week in university students.

A literature search was conducted of research up to June 2017 in the Cochrane library, CINAEL, ERIC, MEDLINE, PsycINFO, PubMed, and Web of Science. Studies were included if they were a random control trial and assessed the effectiveness of E-Interventions at reducing drinks per week, and employed university/college students. 23 studies with 7,614 participants were included.

Weighted mean effect sizes were calculated using random-effects models. These showed a small, significant effect of E-Interventions at reducing the number of alcoholic drinks per week. Moderator analysis found a significant advantage for web-based personalised feedback interventions compared to other E-Interventions.

The analysis concludes that e-Interventions show a small, significant effect at reducing mean alcoholic drinks per week and that personalised feedback E-Interventions showed the strongest effect.
