It is urgent to increase studies aimed at exploring and understanding the role that psychological resilience plays in PwMS. To achieve this objective, an important requirement is to have properly validated instruments that allow exploring psychological resilience in MS patients. The aim of this study was to evaluate the validity and reliability of the 10-item CD-RISC in a sample of Spanish-speaking patients with MS (PwMS).An online multicenter study was conducted on 214 MS patients from 11 Spanish-speaking countries (Argentina, Mexico, Dominican Republic, Chile, Spain, Cuba, Colombia, Uruguay, Paraguay, Peru, and El Salvador). Confirmatory factor analysis (CFA) was performed to assess the factor structure of the 10-item CD-RISC. Model fits were assessed through the χ2/df value, comparative fit index (CFI), and root mean square error of approximation (RMSEA).The 10-item CD-RISC showed good psychometric characteristics in our sample of PwMS. The single-factor model in the CFA yielded a good model fit (χ2=99.380(35), p<.001; χ2/df = 2.83; RMSEA=.090; CFI=.92). Cronbach's alpha of the CD-RISC-10 items version (Spanish version) was .88. The CD-RISC-10 was significantly correlated with quality of life scale (r = .420, p < .001), fear of relapse scale (r = -.327, p < .001), and fatigue scale (r = -.367, p < .001).The CD-RISC-10 has satisfactory psychometric properties and is a suitable tool for measuring resilience in Spanish-speaking patients with multiple sclerosis.
