Abstract
The family plays an immensely crucial role in the development of adolescents, significantly influencing their behavioral patterns. To explore the impact mechanism of the family physical activity environment on adolescents' exercise adherence, and analyze the chain-mediating role of exercise self-efficacy and exercise satisfaction. A questionnaire was administered to 500 adolescents and their parents using the Family Physical Activity Environment Scale, Exercise Adherence Scale, Exercise Self-Efficacy Scale and Satisfaction Scale. The direct impact value of the family physical activity environment on adolescents' exercise adherence is 0.148, with an effect size of 32.81%. The impact values of exercise self-efficacy and satisfaction between the family physical activity environment and adolescents' exercise adherence are 0.113 and 0.092 respectively, with effect sizes of 25.05% and 20.39%. The chain-mediating effect of exercise self-efficacy and satisfaction is significant, with an effect value of 0.097 and an effect size of 21.50%. Family physical activity environment can directly and positively predict adolescents' exercise adherence, positively predict adolescents' exercise adherence through the independent mediating role of exercise self-efficacy and satisfaction, and also positively predict adolescents' exercise adherence through the chain mediating role of exercise self-efficacy and satisfaction. This provides a theoretical reference for enhancing adolescents' exercise adherence and improving their levels of physical health.
