Psychometric properties of the Chinese version of the spiritual care competency scale in nursing practice: a methodological study

OBJECTIVES: To determine the validity and reliability of the Spiritual Care Competency Scale (SCCS) among nurses in China. DESIGN: Methodological research. METHODS: After the SCCS was translated into Chinese, the validity and reliability of the Chinese version of the SCCS (C-SCCS) were evaluated using a convenience sample of 800 nurses recruited from different healthcare centres. The construct validity of the C-SCCS was determined by an exploratory factor analysis (EFA) with promax rotation. Pearson’s correlation coefficients of the C-SCCS and the Palliative Care Spiritual Care Competency Scale (PCSCCS-M) were computed to assess the concurrent validity and construct validity of the C-SCCS. To verify the quality of the component structure, we conducted a confirmatory factor analysis (CFA). We tested the internal consistency and stability of the measure using Cronbach’s alpha coefficient and the Guttman split-half coefficient, respectively, and a factorial analysis was performed. RESULTS: A total of 709 participants completed the questionnaire (response rate: 88.63%), and all completed questionnaires were suitable for analysis. Three factors were abstracted from the EFA and explained 58.19% of the total variance. The Cronbach’s alpha coefficients of the three subscales were .93, .92, and .89, and the Guttman split-half coefficient for the C-SCCS was .84. The CFA indicated a well-fitting model, and the significant correlations between the C-SCCS and the PCSCCS-M (r=0.67, p<0.01) showed adequate concurrent validity. Nurses’ education and income level showed a significant association with the C-SCCS score. CONCLUSION: The C-SCCS was shown to be a psychometrically sound instrument for evaluating Chinese nurses’ spiritual care competencies.
