The goal of this randomized controlled trial is to evaluate the effectiveness of a mindfulness-centered stress management AI chatbot in reducing perceived stress and enhancing mental health among Chinese men who have sex with men (MSM).
The main questions it aims to answer are:
1. Does the AI chatbot show a greater reduction in perceived stress compared to standardized psychoeducational materials? 2. Does the AI chatbot improve mental health outcomes, including depressive and anxiety symptoms, subjective well-being, and emotion regulation?
Researchers will compare the AI chatbot to a control group receiving psychoeducational materials to see if the chatbot works to reduce stress and improve mental health.
Participants will:
1. Be randomized to use the AI chatbot (recommended at least 2 sessions per week, 10-15 minutes per session) or read psychoeducational materials (2 times per week) for 4 weeks. 2. Complete online self-report questionnaires at baseline, post-intervention (Week 4), and 4-week follow-up.
