摘要： 目的探讨自我效能在慢性心力衰竭患者自我调节疲劳与运动依从性之间的中介效应。方法采用便利抽样法,于2022年7月—11月选取南京某三级甲等综合医院就诊的267例慢性心力衰竭患者,使用自我调节疲劳量表、一般自我效能量表、运动依从性量表对其进行问卷调查。结果慢性心力衰竭患者自我调节疲劳总分为（44.31±8.23）分,自我效能总分（23.90±6.66）分,运动依从性总分（29.44±11.59）分。自我调节疲劳与自我效能呈负相关（r=-0.533,P<0.001）,与运动依从性呈负相关（r=-0.405,P<0.001）,自我效能与运动依从性呈正相关（r=0.455,P<0.001）。中介模型显示,自我效能在自我调节疲劳与运动依从性中起部分中介作用,总效应为-0.570,直接效应为-0.319,间接效应为-0.251,中介效应占总效应的 44.0%。结论慢性心力衰竭患者的自我调节疲劳处于较高水平,自我效能处于中等偏低水平,运动依从性处于较低水平。自我调节疲劳、自我效能均可直接影响患者运动依从性,自我调节疲劳也可通过自我效能间接影响患者运动依从性。医护人员应积极采取策略对抗自我调节疲劳,增加自我效能感,从而提高患者的运动依从性。

Abstract: Objective To explore the mediating role of self-efficacy between self-regulatory fatigue and exercise adherence in patients with chronic heart failure (CHF). Methods A total of 267 CHF patients visiting a tertiary grade-A general hospital in Nanjing were conveniently sampled and surveyed by the Self-Regulatory Fatigue Scale, General Self-Efficacy Scale, and the Exercise Adherence Scale from July to November 2022. Results The total score of self-regulatory fatigue, self-efficacy and exercise adherence in CHF patients was 44.31±8.23, 23.90±6.66 and 29.44±11.59 respectively. Self-regulatory fatigue was negatively correlated with self-efficacy (r=-0.533, P<0.001) and exercise adherence (r=-0.405, P<0.001). Self-efficacy was positively correlated with exercise adherence (r=0.455, P<0.001). The mediation model showed that self-efficacy played a partial mediating role between self-regulatory fatigue and exercise adherence. The total effect was -0.570; and direct and indirect effect was -0.319, and -0.251 respectively. The mediating effect accounted for 44.0% of the total. Conclusion CHF Patients present a high level of self-regulatory fatigue, a medium-low level of self-efficacy, and a low level of exercise adherence. Both self-regulatory fatigue and self-efficacy can directly affect patients' exercise adherence, and self-regulatory fatigue can also indirectly affect patients' exercise adherence through self-efficacy. Strategies aimed at alleviating self-regulatory fatigue and enhancing self-efficacy are advantageous in promoting exercise adherence among CHF patients.
