A Randomized Pilot Trial of a Mobile Delivered Brief Motivational Interviewing and Behavioral Economic Alcohol Intervention for Emerging Adults

This study examined the feasibility, acceptability, and preliminary efficacy of live, text-message-delivered brief motivational interventions (BMIs) about alcohol awareness in a pilot randomized clinical trial. Participants were 66 college students reporting an average of 11.88 drinks per week, 4.42 lifetime heavy drinking episodes (HDEs), and 8.44 alcohol-related problems in the past month. Participants were randomized to receive either education or an alcohol BMI plus behavioral economic substance-free activity session (SFAS), each followed by 4 weeks of mini-sessions. All sessions were administered via live text message. Results showed that 90.9% of participants completed both initial full-length sessions and at least two of the four mini-sessions, with 87.9% retention at 3-month follow-up. Participants reported finding the interventions useful, interesting, relevant, and effective, with no between-group differences. There were no statistically significant group differences in drinks per week or alcohol-related problems at follow-up, but BMI-plus-SFAS participants reported fewer past-month HDEs than those who received education.
