We studied physical functioning and social and leisure functioning of 125 men before, 1 month after, and 6 months after coronary artery bypass surgery. Relationships between functional status outcomes and selected psychosocial and physical variables were examined. Although functional status outcomes improved significantly 6 months after surgery, 13% of patients continued to report important functional status disabilities, and 45% reported difficulty in or no participation in moderately vigorous activities. The variable most predictive of functional status was the patient's estimation a priori of his ability to carry out specific activities (self-efficacy). Other psychosocial and physical factors, other than postoperative treadmill performance, did not add significantly to the prediction of the outcomes. Findings suggest that rehabilitative programs attempting to facilitate physical and social reintegration of the patient after coronary artery bypass surgery should test the effects of interventions to increase self-efficacy.
我们研究了125名男性在冠状动脉搭桥手术前、术后1个月和术后6个月的身体功能以及社交和休闲功能。对功能状态结果与选定的心理社会和身体变量之间的关系进行了检查。尽管术后6个月功能状态结果有显著改善，但13%的患者仍报告有重要的功能状态残疾，45%的患者报告难以参与或未参与中等强度的活动。对功能状态最具预测性的变量是患者对自己进行特定活动能力的先验估计（自我效能感）。除术后跑步机表现外，其他心理社会和身体因素对结果预测的贡献并不显著。研究结果表明，旨在促进冠状动脉搭桥手术后患者身体和社会重新融入的康复计划应测试提高自我效能感干预措施的效果。
