Outcome Measures
Primary Outcomes (1)
Mean weekly alcohol consumption
Participants report (1) the average number of days per week they consumed alcohol and (2) the typical number of standard drinks consumed on a drinking day. Estimated weekly alcohol consumption will be calculated as: Mean weekly drinks = (average drinking days per week) Ă— (typical drinks per drinking day)
Baseline, 3-, 6-, and 12-month follow-ups
Secondary Outcomes (2)
Number of heavy drinking days
Baseline, 3-, 6-, and 12-month follow-ups
Number of drinks per drinking day
Baseline, 3-, 6-, and 12-month follow-ups
Study Arms (3)
MICA
EXPERIMENTALMICA is a generative AI-powered counseling agent that delivers brief Motivational Interviewing (MI)-consistent sessions, following the validated MI process (engagement, focusing, evoking, planning, and closing). It uses personalized prompts to promote autonomy and evoke change talk, ending with a session summary and satisfaction check. Participants will complete a MICA session (\~5-10 min) in the ED and at 3 months.
MICA+SMS
EXPERIMENTALThis condition includes the MICA ED session, a 3-month booster, and 12 weeks of weekly SMS messages supporting self-monitoring, goal-setting, and adaptive strategies. Messages are tailored based on reported alcohol use and goal commitment, offering encouragement, feedback, and harm-reduction messaging.
Standard care
NO INTERVENTIONStandard ED care and as-needed referral to alcohol resources
Interventions
MICA is an AI chatbot that uses a secure API with ChatGPT and prompted to follow MI principles to support individuals in exploring and resolving ambivalence about their alcohol use. MICA follows a predefined conversational framework and steps: introduction, engagement, focusing, evoking, planning, and closing-adapted from Miller \& Rollnick's Motivational Interviewing: Helping People Change (3rd ed.).
Weekly SMS check-ins designed to support goal-setting, self-monitoring, and adaptive self-regulation strategies. Beginning the Sunday after enrollment, participants will engage with an automated SMS program once weekly for 12 weeks. Prompts include reporting on the past week's alcohol use and whether they are willing to commit to a drinking limit goal for the upcoming week. Responses trigger tailored feedback.
