The association between physical activity, self-efficacy, stress self-management and mental health among adolescents

This study aimed to explore the interplay between physical activity, self-efficacy, stress self-management and mental health among adolescents. The study gathered data from an online survey conducted among 400 Chinese middle school students (mean age = 13.74 years). The collected data were analyzed using SPSS 27.0 and PROCESS 4.1. The findings indicated a positive and significant relationship between physical activity, self-efficacy, stress self-management, and mental health. Notably, the association between physical activity and mental health was entirely mediated by self-efficacy and stress self-management. Moreover, self-efficacy and stress self-management exhibited a chain mediation effect on the relationship between physical activity and mental health. It is suggested that interventions focusing on physical activity should prioritize strategies for enhancing students' self-efficacy and stress self-management skills as integral components of promoting adolescents' mental health. Future research should delve into identifying specific types of physical activities that have a greater potential to enhance self-efficacy and stress self-management abilities.
