The validity and reliability of the Chinese version of Connor Davidson Resilience Scale in schizophrenia / 中国实用护理杂志

ABSTRACT

Objective:To test the factor structure and psychometric properties of the Chinese version of the Connor Davidson Resilience Scale (CD-RISC) in schizophrenia patients. In order to provide resilience scale for schizophrenia patients in China.Methods:A convenient sampling method was used to select 503 inpatients with schizophrenia in Chifeng Anding hospital from December 2017 to December 2018. The Chinese version of CD-RISC was used to conduct a questionnaire survey. Data processing was performed using SPSS 23.0 statistical software and AMOS 24.0 software.Results:The item analysis showed that the Chinese version of CD-RISC could discriminate the high-score group from the low-score group ( P<0.01). Pearson correlation analysis and principal component analysis showed that the correlation between item 3 and the total amount was poor, and it was considered to be deleted. A total of 6 common factors were extracted from the revised exploratory factor analysis of the CD-RISC, and the cumulative variance contribution rate was 50.79%. The Cronbach α coefficient was 0.882, and the test-retest reliability was 0.912 after two weeks. Confirmatory factor analysis fitted index χ2/ df was 1.057, RMSEA was 0.015, GFI was 0.926, CFI was 0.989, and IFI was 0.989. Conclusions:The revision 24-item CD-RISC has good psychometric properties, it could be used to assess resilience in Chinese patients with schizophrenia.
