Dietary behaviour plays a crucial role in both the onset and the management of coronary artery disease (CAD). To develop effective interventions to modify dietary behaviours of patients, it is fundamental to identify and examine the predictive factors that are relevant to healthy dietary behaviour. The Health Action Process Approach provides a useful framework for understanding and predicting the process of health behaviour. The aim of the current study is to clarify the role and effect of received social support in the HAPA model. A longitudinal sample of 117 CAD patients filled out a questionnaire at three time points. Along with HAPA constructs, dietary behaviour was assessed with a food frequency questionnaire. To investigate the longitudinal associations of the constructs, structural equation modelling with latent variables was employed. In the final model, outcome expectancies and pre-action self-efficacy jointly predicted behavioural intention. In the post-intentional phase, social support served as a mediator between intention and action planning. Moreover, coping planning mediated the relationship between action planning and dietary behaviour. These results confirmed the mediator role of social support in the intention-behaviour relationship. This finding suggests that social support can be a crucial component to facilitate healthy dietary behaviour.
饮食行为在冠心病（CAD）的发生和管理中起着至关重要的作用。为了开发有效的干预措施来改变患者的饮食行为，确定和检查与健康饮食行为相关的预测因素是至关重要的。健康行动过程方法为理解和预测健康行为的过程提供了一个有用的框架。本研究的目的是澄清接受的社会支持在 HAPA 模型中的作用和影响。117 名 CAD 患者的纵向样本在三个时间点填写了一份问卷。除了 HAPA 结构外，还使用食物频率问卷评估饮食行为。为了研究结构的纵向关联，采用潜变量结构方程模型进行分析。在最终模型中，结果预期和行动前自我效能共同预测行为意图。在意图后阶段，社会支持在意图和行动计划之间起到了中介作用。此外，应对计划在行动计划和饮食行为之间起中介作用。这些结果证实了社会支持在意图-行为关系中的中介作用。这一发现表明，社会支持可以成为促进健康饮食行为的关键因素。
