Health literacy, self-efficacy, symptom experience, and social support were key predictors of self-care among patients with heart failure, with final regression models explaining 39.4%, 31.0%, and 44.1% of variance in self-care maintenance, symptom perception, and self-care management, respectively.
Key Findings
Results
Multiple factors influenced self-care maintenance in heart failure patients, including age, employment status, symptom experience, self-efficacy, and social support.
The final regression model for self-care maintenance had an explanatory power of 39.4%.
Study included 134 patients diagnosed with heart failure at a university-affiliated hospital in South Korea.
Data were collected between June and September 2023 using a cross-sectional design.
Self-care was measured using the Self-Care of Heart Failure Index version 7.2.
Results
Health literacy and self-efficacy were the significant predictors of symptom perception in heart failure patients.
The final regression model for symptom perception had an explanatory power of 31.0%.
Symptom perception was one of three self-care dimensions measured by the Self-Care of Heart Failure Index version 7.2.
Independent variables measured included symptom experience, knowledge, health literacy, self-efficacy, and social support.
Data were analysed using multiple regression analyses with SPSS 25.0.
Results
Age, religion, health literacy, self-efficacy, and social support were significant predictors of self-care management in heart failure patients.
The final regression model for self-care management had the highest explanatory power at 44.1%.
Self-care management was one of three self-care dimensions assessed in the study.
Religion was a unique predictor of self-care management that did not appear as a predictor in the other two self-care dimensions.
The study sample consisted of 134 patients from a university-affiliated hospital in South Korea.
Methods
The study was grounded in the situation-specific theory of heart failure self-care to identify predictors across three self-care dimensions.
The three self-care dimensions examined were self-care maintenance, symptom perception, and self-care management.
Independent variables were selected based on the situation-specific theory and included symptom experience, knowledge, health literacy, self-efficacy, and social support.
The cross-sectional study included 134 patients diagnosed with heart failure.
Heart failure is described as 'a rapidly increasing global health concern, necessitating the development of effective self-care strategies for better management.'
Conclusions
Health literacy, self-efficacy, symptom experience, and social support were identified as key predictors of self-care across multiple dimensions in heart failure patients.
Self-efficacy appeared as a significant predictor across all three self-care dimensions: self-care maintenance, symptom perception, and self-care management.
Health literacy was a significant predictor for both symptom perception and self-care management.
Social support was a significant predictor for both self-care maintenance and self-care management.
The authors recommend that 'nurses should assess these factors and provide tailored, literacy-sensitive education and support to strengthen patients' confidence and resources.'
