Influence of Physical and Psychological Symptoms on Exercise Adherence in Patients with Heart Failure: Focused on the Mediating Effects of Self-efficacy

Abstract

Purpose The aim of this study was to examine the mediating effect of self-efficacy in the relationship of physical and psychological symptoms to exercise adherence in patients with heart failure. Methods The participants in this study were 186 patients with heart failure in two hospitals located in Busan. The measures included questions about general and disease characteristics, physical symptoms, psychological symptoms, self-efficacy for exercise, and exercise adherence. Data were analyzed using t-test, ANOVA, Pearson correlation coefficients, simple and multiple regression using Baron and Kenny steps for mediation. Results There were significant differences in age, gender and comorbidity on exercise adherence. There were also significant correlations among physical and psychological symptoms, self-efficacy for exercise, and exercise adherence. Self-efficacy for exercise showed partial mediating effects in the relationship between physical symptoms and exercise adherence. Conclusion Based on the findings of this study, the enhancement of self-efficacy for exercise may positively affect the exercise compliance of the patients with health failure, even while they are experiencing physical symptoms. Therefore, it is necessary to develop effective strategies to enhance self-efficacy for exercise. 주요어: ì‹¬ë¶€ì „, 운동, 자기효능감 Key words: Heart failure, Exercise, Self-efficacy
