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

Background and Objective: 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. Materials and Methods: 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, ۴۴۲ people with MS participated and responded to CD-RISC in an online survey. The data were analyzed in SPSS (version ۲۳) and Amos (version ۲۱) software packages. Results: The confirmatory factor analysis results of the first stage with five factors revealed that ۲۵ CD-RISC items benefited from high factor load and good fit indices were reported (ꭕ۲=۶۰۵.۵۵; df=۲۶۵; P-Value=.۰۰۰۱; ꭕ۲/df=۲.۲۸; GFI=.۸۸; CFI=.۹۳; TLI=.۹۲; RMR=.۰۶; RMSEA=.۰۵); therefore, CD-RISC has good construct validity. Cronbach’s alpha coefficients for the whole scale and subscales were calculated at ۰.۹۴ and ۰.۷۱-۰.۸۹, respectively, indicating the optimal reliability of CD-RISC in PwMS. Conclusions: 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.
