Validation of the Korean Version of the Chronic Kidney Disease Self-Care Scale

Abstract

Purpose: The treatment of chronic kidney disease aims to delay dialysis and prevent progression to end-stage health complications. This study aimed to validate the Korean version of the Chronic Kidney Disease Self-Care (CKDSC-K) scale, which is used to measure self-care behaviors in patients with chronic kidney disease. Methods: Data from 285 participants were collected between August and November 2020. Validity was assessed in terms of content, construct, and concurrence through the content validity index and exploratory and confirmatory factor analyses. The reliability of the CKDSC-K was examined using internal consistency. Results: The final instrument consisted of 15 items across five factors (medication adherence, diet control, exercise, smoking behaviors, and blood pressure monitoring). The content validity index of the CKDSC-K was ≥.80. Confirmatory factor analysis indicated that factor loadings for the five factors ranged from.41 to.99, which explains the total variance of 75.3%. The internal reliability of the instrument was.81. Conclusion: The CKDSC-K scale has demonstrated acceptable reliability and validity and can be utilized to assess self-care behaviours in patients with chronic kidney disease. Additional research is recommended to expand the psychometric evaluation of the CKDSC-K.
