Résumé
Background: The Brief Motivational Intervention (BMI) is an effective treatment for alcohol misuse but has not been adequately tested for use in helplines for alcoholics. The main objective of this study was to evaluate the efficacy of a telephone-based BMI for Brazilians seeking help with alcohol use cessation. Methods: A randomized, controlled trial was performed with Brazilian subjects. Participants were randomly assigned to either the minimal intervention group (i.e., given reference materials) or the BMI group. Alcohol abstinence was evaluated in a 6-month follow-up telephone counseling session. The analysis was based on the intention to treat (ITT). Results: Of the 5,896 drug users who called the helpline, 700 (12%) used alcohol, 637 of whom enrolled in this study. At 6-month follow-up, 70% of the BMI group had stopped consuming alcohol compared to 41% in the control group (odds ratio = 1.5; 95% confidence interval = 1.2-1.9; p = 0.001). Conclusions: A helpline-based BMI helps alcohol users achieve abstinence. .
