Summary

This study aims to evaluate and compare the degree of alcohol reduction between high-risk drinkers who use a motivational interviewing-based conversational agent (chatbot) application for four weeks and those in the control group who do not use the application, in order to verify its clinical effectiveness.

Conditions

  • Alcohol Drinking
  • High-Risk Drinking Patterns

Interventions

BEHAVIORAL

Motivational Interviewing-Based Conversational Agent (Mobile Chatbot)

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.

OTHER

No Intervention (Waitlist Control)

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.
