Treatments tested in this trial

  • Motivational Interviewing-Based Conversational Agent (Mobile Chatbot)

    Behavioral

    Participants in the experimental arm will use a motivational interviewing-based conversational agent (mobile chatbot) for 4 weeks starting on the baseline assessment day (Week 0). The intervention provides daily interactive dialogues, personalized feedback, goal-setting guidance, and behavior change strategies based on motivational interviewing principles. Participants are encouraged to complete daily sessions designed to enhance motivation, support self-monitoring, and reduce high-risk alcohol consumption.

  • No Intervention (Waitlist Control)

    Other intervention

    Participants in the waitlist control arm will not receive any intervention during the primary evaluation period (Week 0-16). They will complete the same reassessments as the intervention group at Week 4 and Week 16. After the Week 16 follow-up, control arm participants will be offered the same 4-week chatbot intervention for ethical considerations, followed by a final assessment at Week 20. This post-Week-16 intervention is not included in the primary efficacy analysis.

Change in Past 7-Day Alcohol Consumption (Standard Drinks and Binge Drinking Frequency) From Baseline to Week 16

Alcohol consumption during the past 7 days-including total standard drink units and binge drinking frequency-will be assessed at Week 0, Week 4, and Week 16 using validated self-report measures. The primary efficacy analysis will evaluate changes from baseline to Week 16 in both past 7-day standard alcohol consumption and past 7-day binge drinking episodes to determine the intervention's effectiveness in reducing high-risk alcohol use.
