MICA
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.).
TRAC
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.
