The psychometric properties of the Korean version of the revised Self-Care of Heart Failure Index (SCHFI) remain undetermined; therefore, we aimed to evaluate the construct and convergent validity and reliability of the Korean version of the SCHFI in Korean patients with heart failure (HF). Using a cross-sectional design, 207 patients with HF provided data on self-care and self-efficacy in self-care for this psychometric testing. The confirmatory factor analysis supported the construct validity of the Korean version with a three-factor structure: Self-Care Maintenance, Symptom Perception, and Self-Care Management. Convergent validity was supported by the significant relationships between self-efficacy and each scale of the Korean version of the SCHFI (r = .425–.549, p < .001). The reliability estimates were marginally adequate, with a Cronbach’s alpha of .655 to .776, McDonald’s omega of .710 to .836, and composite reliability coefficients of .704 to .834. The SCHFI was supported as a valid and reliable measure of self-care for Koreans with HF. However, the marginal levels of the Cronbach’s alpha coefficients still require validation in a larger sample.
