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, 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. results: 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. 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.
