This study examined the direct and mediated contributions of psychosocial variables to posttreatment physical functioning among 142 patients receiving cardiac rehabilitation. Two models were proposed and tested. In the first model, psychosocial factors were correlated and made to predict baseline and 6-week physical functioning. The results showed that after controlling for age, illness severity, baseline physical functioning, and other psychosocial correlates, optimism and social support still significantly predicted better posttreatment physical functioning. In the second model, we explored both the direct and mediational relationships between psychosocial factors and physical health outcomes. Optimism and social support were found to contribute to health outcomes not only directly but also indirectly through the mediation of less engagement in detrimental coping and lower depressive symptoms, whereas hostility and negative coping only predicted outcomes indirectly through mediators. These findings highlighted the importance of addressing psychosocial issues and their interrelationships in cardiac rehabilitation.
本研究考察了心理社会变量对142名接受心脏康复治疗患者治疗后身体功能的直接和中介作用。提出并检验了两个模型。在第一个模型中，心理社会因素相互关联，并用于预测基线和6周时的身体功能。结果显示，在控制了年龄、疾病严重程度、基线身体功能和其他心理社会相关因素后，乐观和社会支持仍然显著预测了更好的治疗后身体功能。在第二个模型中，我们探讨了心理社会因素与健康结果之间的直接和中介关系。研究发现，乐观和社会支持不仅直接有助于健康结果，还通过较少参与有害应对和较低抑郁症状的中介作用间接发挥作用，而敌意和消极应对仅通过中介因素间接预测结果。这些发现突出了在心脏康复中解决心理社会问题及其相互关系的重要性。
