Guided by the Theory of Planned Behavior (TPB; Ajzen, 1991), this study aimed to test a hypothesized path model of TPB variables (i.e., attitude toward behavior, subjective norm, perceived behavioral control, and intention) with physical activity (PA) and depressive symptoms. A total of 792 Chinese adolescents ( = 16.9; = 0.82; 54.5% females) completed previously validated questionnaires assessing their TPB variables, PA, and depressive symptoms. Correlation analysis revealed TPB variables were positively associated with PA ( < 0.01), and negatively correlated to depressive symptoms ( < 0.01). The path analyses indicated that the hypothesized model produces a goodness of fit (χ/df = 16.14/5, CFI = 0.99, RMSEA = 0.06). The findings support the theoretical tenets of TPB and provide empirical evidence of the psychosocial mechanism of PA and depressive symptoms in Chinese adolescents. It suggests that building PA intervention strategies while considering the TPB framework may promote adolescents' physical and mental health.
本研究以计划行为理论（TPB；Ajzen，1991）为指导，旨在检验 TPB 变量（即行为态度、主观规范、感知行为控制和意向）与身体活动（PA）和抑郁症状的假设路径模型。共有 792 名中国青少年（=16.9；=0.82；54.5%女性）完成了先前验证过的问卷，评估了他们的 TPB 变量、PA 和抑郁症状。相关分析显示，TPB 变量与 PA 呈正相关（<0.01），与抑郁症状呈负相关（<0.01）。路径分析表明，假设模型产生了良好的拟合度（χ/df=16.14/5，CFI=0.99，RMSEA=0.06）。研究结果支持 TPB 的理论原则，并为中国青少年 PA 和抑郁症状的心理社会机制提供了实证证据。这表明，在考虑 TPB 框架的情况下制定 PA 干预策略，可能会促进青少年的身心健康。
