A psychometric assessment for evaluating spiritual care competency for geriatric nurses

Abstract

This study evaluates the validity and reliability of the Chinese Version of Spiritual Care Competency (C-SCC) for geriatric nurses. Using convenience and snowball sampling, 1,094 geriatric nurses were randomly divided into two groups of 547 each for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). EFA confirmed a four-dimensional structure, explaining 74.399 % of the total variance. Structural validity was assessed through EFA and CFA, while correlation analysis evaluated concurrent and convergent validity. Internal consistency, measured by Cronbach's α coefficient, was 0.987, with individual factors scoring 0.983, 0.964, 0.933, and 0.976. Test-retest reliability was 0.983, and concurrent validity was 0.860 (P < 0.01). Modified CFA results (RMSEA = 0.04, GFI = 0.93, AGFI = 0.93, NFI = 0.93, RFI = 0.93, PGFI = 0.62) indicated a well-fitting model with excellent psychometric properties. The C-SCC is a reliable tool for assessing spiritual care competencies among geriatric nurses.
