Descrição detalhada
This study aims to evaluate the effectiveness of VIPeerAgent, an artificial intelligence-powered virtual peer support agent, in promoting mental health among adolescents and young adults aged 14-25 years who experience psychological distress but do not meet diagnostic criteria for a mental disorder. The study is designed to support the early identification, early intervention, and prevention of mental health problems in youth populations.
The study adopts a three-arm parallel randomized controlled trial with a non-inferiority and superiority testing framework. Eligible participants will be randomly assigned in a 1:1:1 ratio to one of three groups: (1) the VIPeerAgent intervention group, (2) the human peer mentor support group, or (3) the usual-care control group.
Participants in the VIPeerAgent group will engage in multi-turn conversations with the virtual peer agent. The intervention focuses on providing psychological support in three key areas: emotional awareness and regulation, social support enhancement, and coping strategy development. At the end of each interaction, VIPeerAgent will guide participants in developing an individualized and actionable to-do list based on their personal needs and goals. Additional support will be provided through proactive follow-up and personalized content recommendations tailored to participants' psychological needs.
Participants in the human peer mentor group will receive support from trained peer mentors. The intervention components are comparable to those delivered by VIPeerAgent and include peer support consultations, enhanced follow-up, individualized action planning through to-do lists, and personalized supportive messages. Participants in the usual-care control group will receive routine mental health education through weekly mental health promotion materials. The intervention period will last four weeks.
The primary outcome is improvement in mental health status during the follow-up period, assessed using the Brief Symptom Inventory-53 (BSI-53). Secondary outcomes include psychological resilience, coping strategies, perceived social support, and emotional intelligence.
In addition to the randomized controlled trial, an explanatory qualitative study will be conducted following completion of the intervention. Using purposive sampling, participants with diverse experiences and intervention responses will be invited to participate in semi-structured interviews. The qualitative interviews will explore participants' perceptions of the intervention, user experiences, acceptability, engagement, and perceived impact. Findings from the qualitative analysis will be used to complement and help explain the quantitative trial results, providing a deeper understanding of the mechanisms, benefits, and implementation considerations of AI-assisted peer support for youth mental health.
This design will generate comprehensive evidence regarding both the effectiveness and user experience of VIPeerAgent and inform the future development, implementation, and scalability of AI-supported mental health interventions for adolescents and young adults.

It comprises 27 items covering five domains: punishment, loss, interpersonal stress, academic stress, and adaptation problems.
Each item is rated on a 6-point scale from 0 (never occurred) to 5 (extremely severe).
Scale range: 0 to 135 Higher scores indicate a worse outcome (greater negative impact of stressful life events).
