다국어 초록 (Multilingual Abstract)

Purpose: This methodological study evaluated the psychometric properties of the Self-Care of Coronary Heart Disease Inventory version 3 (SC-CHDI v3) in a Korean context.
Methods: The SC-CHDI v3 was translated into Korean following a rigorous translation process. Participants were 452 patientswhohad experienced coronary heart disease (CHD), all recruited froma tertiary hospital in Korea. Exploratory and confirmatory factor analyses were performed to test construct validity. Concurrent validity was examined by correlating scores from the Korean version of the SC-CHDI v3 with those from the Cardiac Self-Efficacy Scale. Internal consistencywas analyzed using Cronbach's alpha andMcDonald's omega.
Results: The Korean version of the SC-CHDI v3 consists of 21 items, excluding two from the original instrument. The self-care maintenance subscale identified a two-factor structure: “treatment adherence” and “health-promoting behaviors.” The goodness-of-fit indices were satisfied: c2 ¼ 18.19, p ¼ .110, comparative fit index (CFI) ¼ .97, Tucker-Lewis Index (TLI) ¼ .95, and standardized root mean square residual (SRMR) ¼ .04. The self-care monitoring subscale consisted of a one-dimensional structure (“monitoring behaviors”) and the goodness-of-fit indices were satisfied: c2 ¼ 19.19, p ¼ .059, CFI ¼ .99, TLI ¼ .99, and SRMR ¼ .04. The self-care management subscales had a two-factor structure of “consulting behaviors” and “problem-solving behaviors.” The goodness-of-fit indices were satisfied: c2 ¼ 16.44, p ¼ .037, CFI ¼ .99, TLI ¼ .98, and SRMR ¼ .03. Scores from the Cardiac Self-Efficacy Scale showed a positive correlation with the Korean version of SC-CHDI v3 subscales. Reliability estimates were .80 for all subscales except for the self-care maintenance subscale.
Conclusions: The Korean version of the SC-CHDI v3 consists of 21 items in 3 subscales and is a valid and reliable instrument. Therefore, healthcare providers can effectively utilize it to assess the self-care levels of patients with CHD.
