ABSTRACT
BACKGROUND:
Heart failure (HF) is a chronic heart condition that requires patients to adapt to the disease and maintain a high degree of self-management. Patients with HF commonly feel loss of control, which has a negative effect on their compliance to self-care, health-related quality of life, and health outcomes. To promote self-care behavior and to develop healthy coping mechanisms, it is important to understand individual HF patients' perceived control, a self-generated belief that one has the ability to bring forth desired outcomes. Currently, there is no valid and reliable Korean instrument available in measuring perceived control among patients with HF.OBJECTIVE:
The objective of this study was to cross-culturally translate, adapt, and evaluate psychometric properties of the Korean version of Control Attitudes Scale-Revised (KCAS-R) in Korean patients with HF.METHODS:
The KCAS-R was developed using a translation/back-translation process and an examination of semantic and conceptual equivalence. Reliability was assessed using Cronbach α to determine internal consistency, and item-total and interitem correlations were assessed to test item homogeneity. The construct validity was examined using exploratory factor analysis, confirmatory factor analysis, and testing hypotheses for known associations with self-efficacy, self-care confidence, and self-care.RESULTS:
A convenience sample of 138 patients with HF were included for the psychometric testing of an 8-item KCAS-R. The Cronbach α for internal consistency was 0.835, and the item-total correlation was acceptable. The construct validity revealed a 2-factor structure accounting for 63.23% of the total variance. The KCAS-R was associated with higher levels of self-efficacy, self-care confidence, and self-care. In addition, patients with higher perceived control had less depression and anxiety compared with those with lower levels of perceived control.CONCLUSION:
This study provided support for the satisfactory reliability and validity of the 8-item KCAS-R in measuring perceived control in Korean patients with HF.
