The participants, 350 middle school students in Seoul and Gyeonggi province were surveyed. For accomplishing this purpose of the study, the survey quesionnaires were used to collect data. The reliability and construct validity of the questionnaire survey were evaluated with Cronbach’s avalues, descriptive statistics, correlation analysis, and standard multiple regression analysis. The mediation model of self-efficacy was verified by structural equation modeling(SEM). From the analysis, the following conclusions were obtained: Firstly, Perceived leisure perception partially influence on self efficacy in adolescence. Secondly, Perceived leisure perception partially influence on stress coping behavior in adolescence. Thirdly, Self-efficacy partially influence on stress coping behavior in adolescence. Fourth, it was elucidated that self-efficacy of adolescents mediates between leisure perception and stress coping of the group. And Also leisure perception of adolescents had significant effect on the stress coping of them directly. Also leisure perception of adolescents affected self-efficacy, and then the affected self-efficacy of adolescents significantly affected stress coping of the group. As the students in adolescence perceive leisure perception more highly, self-efficacy gets improved. Subsequently, the improved self-efficacy may have an improving effect on stress coping skill of adolescents.
