Abstract
BACKGROUND: No validated tool is available to assess patients' perception of physician empathy in Korea. The objective of this study was to establish a Korean version of the Consultation and Relational Empathy (CARE) measure-originally developed in English and widely used internationally-and to examine its reliability and validity. METHODS: The CARE measure was translated into Korean and tested on 240 patients from one secondary care hospital and one tertiary care hospital in Korea. Internal consistency by Cronbach's alpha, exploratory analysis, and confirmatory factor analysis were conducted to verify the 10 items of the Korean CARE measure. RESULTS: The Korean CARE measure demonstrated high acceptability and face validity, excellent internal reliability (Cronbach's alpha = 0.97) and moderate test-retest reliability (Pearson correlation coefficient = 0.53; Spearman correlation coefficient = 0.51). Distribution of scores showed negative skewedness. Corrected item-total correlations ranged from 0.77-0.92, indicating homogeneity. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.949, and Bartlett's test of sphericity was good (χ2 = 3157.11, P < 0.001). Factor analysis yielded a single dimensional structure of physician empathy with all factor loadings exceeding 0.80 and showing excellent goodness of fit. CONCLUSION: This study supports the reliability and validity of the Korean CARE measure in a university hospital setting in Korea.
