Abstract
AIM: The purpose of this study was to validate the Cardiac Health Behavior Scale for Korean adults (CHB-K) to determine its validity and reliability. BACKGROUND: Cardiovascular diseases (CVDs) are one of the most important chronic diseases due to their high prevalence and mortality rates. Patients with cardiovascular risks or diseases need to perform appropriate cardiac health behaviors that help to prevent the progression of the disease and improve their health status. METHODS: This secondary analysis obtained data from two clinical trials of cardiac rehabilitation. Data from 298 patients with cardiovascular risks or diseases were analyzed for validation. Data analyses included correlation coefficients, t-tests, and exploratory and confirmatory factor analyses using SPSS (version WIN 22.0) and AMOS (version 20.0). The Self-Efficacy Scale was used to assess convergent validity, while reliability was assessed using Cronbach's alpha coefficients. RESULTS: Five main factors were verified: health responsibility, physical activity, diet habit (eating habit and food choice), stress management, and smoking cessation. A set of 21 items from the 25-item scale was verified after performing item analysis, factor analyses, and critical evaluation of the statistical results. The 21-item CHB-K (CHB-K21) exhibited acceptable validity, and the model of the CHB-K21 provided a good fit to the data. Most of the factors were found to be moderately correlated with SES scores (r=0.45-0.52, p<0.001). The CHB-K21 also demonstrated acceptable reliability (Cronbach's alpha=0.83). CONCLUSIONS: The CHB-K21 demonstrates strong validity and reliability. It can be used to assess cardiac health behaviors in Korean adults with cardiovascular risks or diseases.
