Clinical trials

The goal of this clinical trial is to learn if a combined intervention of summer camp and letter-writing support works to improve psychological resilience in disadvantaged adolescents in Liangshan, Sichuan. The main questions it aims to answer are: Does the "summer camp + letter-writing" intervention improve resilience in adolescents who face poverty, lack of parental care, or social risks? Does this intervention reduce depression and anxiety symptoms? Researchers will compare adolescents who join the summer camp and receive monthly letters to those who do not receive this program to see if the intervention helps their mental health and coping skills. Participants will: Attend a 5-day summer camp that includes group games, emotion expression activities, life education, and learning support Receive monthly letters from trained university student volunteers for about 10 months after the camp. The letters will encourage them, give advice, and help them practice what they learned in the camp Complete surveys about their resilience, depression, and anxiety before the intervention, during it, at the end, and 6 months later This study will also look at whether the program is cost-effective, meaning if it brings mental health benefits at a reasonable cost.
