dc.description.abstract This study assessed the psychometric properties of the SF-36 questionnaire in a sample of 4344 Peruvian people aged 15 to 64 years. Internal consistency reliability was estimated using Cronbach's alpha coefficient, construct validity by known-groups comparison defined with respect to key sociodemographic characteristics, and factor structure by confirmatory factor analysis (CFA) at item level. Cronbach's alpha coefficient for the full questionnaire was 0.82 and ranged between 0.66 and 0.92 by scales. The 8 scales discriminated well between sexes, age, and socioeconomic groups. CFA showed that a model with 8 first-order factors and 2 second-order factors (namely, physical and mental health) was a feasible representation of the SF-36 factor structure and had better fit to data than alternative factor structures. The SF-36 showed appropriate psychometric properties regarding internal consistency, construct validity, and factor structure when tested in Peru. Future studies should focus on testing other psychometric properties of the SF-36, such as convergent and discriminant validity, test-retest reliability, and sensitivity to change. en_US
