Physical activity (PA) plays a crucial role in the management of coronary artery disease (CAD). The Health Action Process Approach provides a useful framework for understanding and predicting the process of health behaviors. The aim of the current study was to unveil the role of received social support in the HAPA model, concerning the physical activity of CAD patients. A longitudinal sample of 117 CAD patients filled out a questionnaire during three measurement points (baseline, 2 months, and 6 months later). The constructs within the model were measured by the previously validated HAPA scales. PA was assessed with four items, which were also included in the HAPA questionnaire. To test the direct and indirect associations between the variables, structural equation modeling with latent variables was employed. Received social support was proven to have a significant and strong effect on both action planning and action control, suggesting a synergistic effect on the individual factors, as well as increasing the explained variance of PA. Results confirmed the important role of received social support in the PA of CAD patients. It could be presumed that strengthening the social support from family and friends could support the regular physical activity of CAD patients.

接受的社会支持在冠心病患者身体活动中的作用：健康行动过程方法

体力活动 (PA) 在冠状动脉疾病 (CAD) 的管理中起着至关重要的作用。健康行动过程方法为理解和预测健康行为过程提供了一个有用的框架。本研究的目的是揭示获得的社会支持在 HAPA 模型中的作用，涉及 CAD 患者的身体活动。117 名 CAD 患者的纵向样本在三个测量点（基线、2 个月和 6 个月后）填写了一份问卷。模型中的构造是通过先前验证的 HAPA 量表测量的。PA用四个项目进行评估，这些项目也包含在HAPA问卷中。为了测试变量之间的直接和间接关联，采用了具有潜在变量的结构方程建模。事实证明，获得的社会支持对行动计划和行动控制都有显着而强烈的影响，表明对个体因素有协同作用，并增加了 PA 的解释方差。结果证实了接受的社会支持在 CAD 患者 PA 中的重要作用。可以推测，加强家人和朋友的社会支持可以支持 CAD 患者的正常体育活动。
