The purpose of this study was to examine the associations of social support and self-efficacy with physical Activity (PA) and the mediating effect of self-efficacy on the relationship between social support and PA in Chinese adolescents. Participants included a total of 2341 Chinese adolescents (aged 12.75 ± 1.46 years). Self-reported instruments, including the physical activity questionnaire for adolescents, the social support revalued scale and the exercise self-efficacy scale, were used to measure physical activity, social support and exercise self-efficacy. Results showed that social support (r = 0.29, < 0.05) and exercise self-efficacy (r = 0.43, < 0.05) were significant and positive predictors of PA among Chinese adolescents, and exercise self-efficacy was a significant mediator in the relationship between social support and PA (standardized effect size = 0.15, < 0.001). Such findings were evident with similar patterns in both male and female adolescents. The findings of this study have indicated the importance of social support and exercise self-efficacy on PA promotion in adolescents, which will aid the development of effective interventions in this population.
本研究旨在探讨社会支持和自我效能感与身体活动（PA）之间的关联，以及自我效能感在中国青少年社会支持与PA关系中的中介作用。研究对象包括总共2341名中国青少年（年龄12.75±1.46岁）。采用自我报告工具，包括青少年身体活动问卷、社会支持重新评估量表和运动自我效能量表，来测量身体活动、社会支持和运动自我效能感。结果显示，社会支持（r = 0.29，<0.05）和运动自我效能感（r = 0.43，<0.05）是中国青少年PA的显著正向预测因素，并且运动自我效能感在社会支持与PA的关系中是一个显著的中介变量（标准化效应量=0.15，<0.001）。在男性和女性青少年中均呈现出类似模式，这些发现很明显。本研究结果表明社会支持和运动自我效能感对促进青少年PA的重要性，这将有助于制定针对该人群的有效干预措施。
