【摘要】 目的：探讨自信心和心理韧性在课外体育锻炼与生活满意度之间的中介作用。方法：采用体育锻炼等级量表、儿童青少年自信量表、儿童青少年生活满意度量表、青少年心理韧性量表对1 009名小学五、六年级学生（男519人，女490人；五年级576人，六年级433人）进行团体心理测量，并采用结构方程模型与Bootstrap方法对自信心、心理韧性进行中介作用检验与效应分析。结果：1）课外体育锻炼与生活满意度之间存在正相关（r=0.218），但对生活满意度的直接预测作用不显著（P=0.517）;2）课外体育锻炼可以正向预测自信心（P<0.01），自信心可以正向预测心理韧性（P<0.01）和生活满意度（P<0.01），心理韧性可以正向预测生活满意度；3）自信心和心理韧性在课外体育锻炼和生活满意度之间起显著的中介作用（P<0.01）。中介效应由2条路径产生的间接效应组成，一是课外体育锻炼通过影响自信心间接影响生活满意度（95%CI:0.128,0.267），二是课外体育锻炼通过自信心到心理韧性的链式中介效应进一步作用于生活满意度（95%CI:0.109,0.209）。结论：1）课外体育锻炼能够显著正向预测小学高年级学生的自信心水平；2）课外体育锻炼不能直接影响生活满意度，但课外体育锻炼能通过自信心单独间接影响小学高年级学生的生活满意度，也可以通过自信心和心理韧性的链式中介作用间接影响小学高年级学生的生活满意度。更多还原

【Abstract】 Objective: To explore the mediating effect of self-confidence and psychological resilience on the relationship between extracurricular physical exercise and life satisfaction. Methods: A package of surveys were administered to 1 009 upper elementary students(519 boys and 490 girls; 576 fifth graders and 433 sixth graders), which including the scale of physical exercise level, the children and adolescent self-confidence scale, the children and adolescent life satisfaction scale, and the adolescent resilience scale. Structural equation model and Bootstrap were used to analyze the data to investigate the chain mediating effect of self-confidence and psychological resilience. Results: 1) There was a positive correlation between extracurricular physical exercise and life satisfaction(r=0.218), but the prediction effect on life satisfaction was not significant(P=0.517); 2) extracurricular physical exercise positively predicted self-confidence;self-confidence positively predicted psychological resilience and life satisfaction; and psychological resilience positively predicted life satisfaction; 3) self-confidence and psychological resilience play an intermediary role between extracurricular physical exercise and life satisfaction.The mediating effect consists of two indirect effects: from extracurricular physical exercise to self-confidence and then to life satisfaction(95% CI: 0.128,0.267), from extracurricular physical exercise to self-confidence, to psychological resilience, and then to life satisfaction(95% CI:0.109,0.209). Conclusions: 1) Extracurricular physical exercise significantly and positively predicted the self-confidence of upper elementary students; 2) the extracurricular physical exercise of upper elementary students had no direct effect on life satisfaction, but it indirectly affected the life satisfaction of upper elementary students through their levels of self-confidence, and it had an indirect effect on life satisfaction of upper elementary students through the chain mediators of self-confidence and psychological resilience.更多还原
