This study examined the relationships among cognitive acceptance, behavioral commitment, psychological need satisfaction, autonomous extrinsic motivation (EM) for physical activity (PA), and PA behavior. Participants (N = 456, M age = 40.7 years) completed online measures of these variables, and data were analyzed using structural equation modeling. Results indicated a direct pathway from behavioral commitment to autonomous EM, plus indirect effects via autonomy, competence, and relatedness. There was no direct pathway from cognitive acceptance to autonomous EM, but there were indirect effects via competence and autonomy satisfaction. There was a direct pathway from cognitive acceptance to self-reported PA plus indirect effects via autonomous EM. There was no direct pathway from behavioral commitment to self-reported PA, but there were indirect effects via autonomous EM. Cognitive acceptance and behavioral commitment potentially support the development of autonomous EM for PA. Future research using longitudinal and intervention-based research designs is required to determine the causal relationships among these variables.
本研究考察了认知接受、行为承诺、心理需求满足、身体活动（PA）的自主外在动机（EM）与PA行为之间的关系。参与者（N = 456，年龄中位数 = 40.7岁）完成了这些变量的在线测量，并使用结构方程模型对数据进行了分析。结果表明，从行为承诺到自主EM存在直接路径，此外还通过自主性、能力和关联性产生间接效应。从认知接受至自主EM不存在直接路径，但通过能力和自主性满足存在间接效应。从认知接受至自我报告的PA存在直接路径，此外通过自主EM产生间接效应。从行为承诺至自我报告的PA不存在直接路径，但通过自主EM产生间接效应。认知接受和行为承诺可能有助于PA自主EM的发展。需要使用纵向和基于干预的研究设计进行未来研究，以确定这些变量之间的因果关系。
