Reliability and validity of the 10-item resilience sale in Chinese community-dwelling adults / 中华行为医学与脑科学杂志

ABSTRACT

Objective:To explore the reliability and validity of the 10-item Connor-Davidson resilience scale (CD-RISC-10) in Chinese community-dwelling adults.Methods:Using multistage stratified sampling, totally 2 051 community-dwelling adults were selected and they were investigated by the 10-item Connor-Davidson resilience scale, the center for epidemiological studies depression scale (CES-D) and 10-item Kessler psychological distress scale (K10). The exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to evaluate the CD-RISC-10 by SPSS 22.0 and AMOS 22.0.A parallel analysis and Velicer's minimum average partial (MAP) test were also supplemented to confirm the EFA-derived structure of the scale.Results:The Cronbach α coefficient of the CD-RISC-10 was 0.94, and the Spearman-Brown reliability was 0.89.The total correlation of the questions ranged from 0.74 to 0.81 (all P<0.01). The exploratory factor analysis retained its single dimension, which can explain 63.24% of the total variance.Confirmatory factor analysis revealed the single factor model fit data adequately ( χ2/ df=4.596, CFI=0.967, TLI=0.973, RMSEA=0.065). The resilience(27.02±13.50) was negatively correlated with depression(9.75±5.24) and psychological distress (19.23±6.37)( r=-0.32, -0.35, both P<0.01). Conclusion:The CD-RISC-10 scale has acceptable reliability and validity, with using easily and conveniently.Therefore, it is an effective tool for measuring the resilience of the community-dwelling adults.
