Purpose: The aim of this study was to examine the validity and reliability of the Korean Version of the Spiritual Care Competence Scale (KSCCS). Methods: A cross-sectional study design was used. The K-SCCS consisted of 26 questions to measure spiritual care competence of nurses. Participants, 228 nurses who had more than 3 years’experience as a nurse, completed the survey. Confirmatory factor analysis was used to examine the construct validity and correlations of K-SCCS and spiritual well-being (SWB) were used to examine the criterion validity of K-SCCS. Cronbach’s alpha was used to test internal consistency. Results: The construct and the criterion-related validity of K-SCCS were supported as measures of spiritual care competence. Cronbach’s alpha was .95. Factor loadings of the 26 questions ranged from .60 to .96. Construct validity of K-SCCS was verified by confirmatory factor analysis (RMSEA=.08, CFI=.90, NFI=.85). Criterion validity compared to the SWB showed significant correlation (r=.44, p qqqlt;.001). Conclusion: The findings suggest that K-SCCS serves as an appropriate measure of spiritual care competence with validity and reliability. However, further study is needed to retest the verification of the factor analysis related to factor 2 (professionalisation and improving the quality of spiritual care) and factor 3 (personal support and patient counseling). Therefore, we recommend using the total score without distinguishing subscales.
