Abstract: Objective: To explore the reliability and validity of the Spirituality Index of Well-Being (SIWB) in the elderly community in China, and to provide a reliable measurement tool for the study of spiritual well-being of the elderly in China. Methods: The 557 valid questionnaires were collected from the elderly over 60 years old. The reliability and validity of the scale were tested by Cronbach's α coefficient, exploratory factor analysis and confirmatory factor analysis. Results: The Cronbach's α coefficient of SIWB was 0.925, which had good internal consistency. The Item Content Validity Index of the SIWB was 0.800-1.000, the Scale Content Validity Index/Universal Agreement was 0.833, and the Scale-Content Validity Index/Average was 0.976. The results of exploratory factor analysis showed that the scale was a two factor structure, the factor load of each item was greater than 0.50; the results of confirmatory factor analysis showed that: χ2/df=1.72, GFI=0.946, CFI=0.976, RMSEA=0.021, IFI=0.977, AGFI=0.920, PGFI=0.643, PNFI=0.760, indicating that the fitting degree of each index was good. Conclusion: The SIWB is an effective and reliable tool for measuring spiritual well-being, which provides a feasible and effective tool for evaluating the mental health status of the elderly in China in the future.
