abstract

  • OBJECTIVE: To determine the association between self-efficacy and health-related quality of life (HRQoL) in people with Chronic Obstructive Pulmonary Disease (COPD) and the moderating effect of self-efficacy type (exercise task, exercise barrier, COPD symptom, general) and HRQoL type (generic, COPD specific). METHODS: Databases were searched systematically from inception to January 2019. Methodological quality was assessed, and a meta-analysis was conducted following PRISMA guidelines (PROSPERO protocol: CRD42018114846). RESULTS: Across 31 coefficients, there was a positive relationship between self-efficacy and HRQoL (r = 0.38, 95 %CI [0.32, 0.45]). Exercise barrier self-efficacy had the strongest relationship to HRQoL (r = 0.42, 95 % CI [0.30, 0.52]), followed by COPD symptoms (r = 0.41, 95 % CI [0.33, 0.49]), exercise tasks (r = 0.40, 95 % CI [0.29, 0.50]), and general self-efficacy (r = 0.21, 95 % CI [0.14, 0.28]). Generic HRQoL had a similar relationship to self-efficacy (r = 0.38, 95 % CI [0.28, 0.47]) as COPD specific HRQoL (r = 0.38, 95 % CI [0.30, 0.46]). CONCLUSION: There is a moderate positive relationship between self-efficacy and HRQoL in COPD, with the relationship stronger for exercise and COPD symptoms than general self-efficacy.
