Using e-mail boosters to maintain change after brief alcohol interventions for mandated college students: A randomized controlled trial.

摘要: OBJECTIVE Brief motivational interventions (BMIs) reduce drinking in the short term, but these initial effects often decay. We tested hypothesis that theory-based e-mail boosters would promote maintenance of change after a BMI. METHOD Participants were students (N = 568; 72% male) who violated campus alcohol policy and mandated to participate an alcohol-risk-reduction program. provided baseline data, received BMI, then completed 1-month post-BMI survey. Next, they randomized receive 12 booster e-mails contained either (a) norms or (b) structurally equivalent general health information (control). Alcohol consumption alcohol-related consequences assessed at baseline, 1, 3, 5, 8, months. RESULTS As expected, we observed significant reductions both BMI (ps .05). Latent growth curve models revealed no condition on changes latent variable from 1- 12-month follow-ups (b .01, SE p > Unexpectedly, main effect emerged for self-reported .03, .01); more containing than information. Outcomes not moderated by sex, 1 month, exposure, there was mediation descriptive norms, injunctive peer communication.
