We examine prospectively the role of specific forms of self-efficacy in the physical and role function for patients with coronary heart disease after controlling for the effects of anxiety and depression.
A 6-month prospective cohort study was conducted after cardiac catheterization of 198 HMO members, demonstrating clinically significant coronary disease. Coronary disease severity was assessed through cardiac catheterization; physical function, role function, anxiety, depression, and self-efficacy were assessed through questionnaires.
The Cardiac Self-Efficacy Scale had two factors (maintain function and control symptoms) with high internal consistency and good convergent and discriminant validity. In multiple regression models, the self-efficacy scales significantly predicted physical function, social function, and family function after controlling for baseline function, baseline anxiety, and other significant correlates.
Self-efficacy to maintain function and to control symptoms helps predict the physical function and role function, after accounting for coronary disease severity, anxiety, and depression in patients with clinically significant coronary disease. Interventions to improve self-efficacy may have a broader applicability in the heart disease population than previously appreciated.
在控制焦虑和抑郁影响的情况下，前瞻性地研究特定形式的自我效能感在冠心病患者身体功能和角色功能中的作用。
对198名经心脏导管检查显示患有具有临床意义的冠心病的健康维护组织（HMO）成员进行了一项为期6个月的前瞻性队列研究。通过心脏导管检查评估冠心病严重程度；通过问卷调查评估身体功能、角色功能、焦虑、抑郁和自我效能感。
心脏自我效能量表有两个因子（维持功能和控制症状），具有高内部一致性以及良好的聚合效度和区分效度。在多元回归模型中，在控制了基线功能、基线焦虑和其他显著相关因素后，自我效能量表显著预测了身体功能、社会功能和家庭功能。
在考虑了具有临床意义的冠心病患者的冠心病严重程度、焦虑和抑郁因素后，维持功能和控制症状的自我效能感有助于预测身体功能和角色功能。改善自我效能感的干预措施在心脏病患者中的适用性可能比之前认为的更广泛。
