Validity and Reliability of Connor-Davidson Resilience Scale in Patients with Multiple Sclerosis: A Psychometric Study in Iran

Resilience refers to a protective factor that reduces stress in people with multiple sclerosis (PwMS). Given the significance of this issue, the present research aimed to assess the validity and reliability of the Connor-Davidson Resilience Scale (CD-RISC) in PwMS.

The present cross-sectional study aimed to assess the psychometric properties of CD-RISC in the statistical population of Guilan MS Society (GMSS). In this study, 442 people with MS participated and responded to CD-RISC in an online survey. The data were analyzed in SPSS (version 23) and Amos (version 21) software packages.

The confirmatory factor analysis results of the first stage with five factors revealed that 25 CD-RISC items benefited from high factor load and good fit indices were reported (ꭕ2=605.55; df=265; P-Value=.0001; ꭕ2/df=2.28; GFI=.88; CFI=.93; TLI=.92; RMR=.06; RMSEA=.05); therefore, CD-RISC has good construct validity. Cronbach’s alpha coefficients for the whole scale and subscales were calculated at 0.94 and 0.71-0.89, respectively, indicating the optimal reliability of CD-RISC in PwMS.

The current study presented evidence for CD-RISC validity and reliability. Further studies are recommended to ensure the psychometric properties of this scale in other chronic patients.
