Hand in Hand, We Rise (Xie Shou Gong Jin)

This study aims to conduct a cluster randomized controlled trial to assess the feasibility of implementing the "Hand in Hand, We Rise" (Xie Shou Gong Jin) multi-stakeholder collaborative school-based suicide prevention program in rural public junior high schools. Six schools will be randomly assigned in a 1:1 ratio to either the intervention group or the control group; the intervention group will simultaneously implement the "Youth Strengths \& Skills Curriculum (YSSC)" curriculum for students, "Life Gatekeeper" training for teachers, and mental health information dissemination for caregivers. The primary objectives are to evaluate recruitment, retention, adherence, implementation fidelity, acceptability, and safety within real-world school settings, and to preliminarily estimate changes in indicators such as suicidal ideation, depression, anxiety, loneliness, help-seeking attitudes, mental health stigma, self-esteem, school climate, and bullying. The findings will provide parameters and an implementation basis for a subsequent large-scale, multi-school cluster randomized controlled trial.
