![]() The Portuguese version of the Maslach Burnout Inventory for students showed adequate reliability and validity, but its factor structure was not invariant between the countries, indicating the absence of cross-cultural stability. Invariance of the instrument between the Brazilian and Portuguese samples was not observed (λ:χ²dif = 84.768, p<0.001 Cov: χ²dif = 129.206, p < 0.001 Residues: χ²dif = 518.760, p < 0.001). The assessment of the divergent validity was impaired by the approach of the theoretical concept of the dimensions Exhaustion and Disengagement of the Portuguese version with the Beck Depression Inventory. The concurrent validity of the Portuguese version with the Copenhagen Inventory was adequate (r = 0.21, 0.74). The three-factor model of Exhaustion, Disengagement and Efficacy showed good fit (c 2/df = 8.498, CFI = 0.916, GFI = 0.902, RMSEA = 0.086). The invariance of the model between the Brazilian and the Portuguese samples was assessed. ![]() Concurrent validity was estimated by the correlational analysis of the mean scores of the Portuguese version and the Copenhagen Burnout Inventory, and the divergent validity was compared to the Beck Depression Inventory. The discriminant validity was assessed, and the internal consistency was estimated by the Cronbach's alpha coefficient. Convergent validity was estimated by the average variance extracted and composite reliability. No obstante, desde esta primera época hasta la actualidad, el estudio del burnout ha pasado por distintas etapas. To verify the stability of the factor solution according to the original English version, cross-validation was performed in 2/3 of the total sample and replicated in the remaining 1/3. por Maslach y Jackson cuando se establecen unos criterios de evaluación de dicho síndrome y se extiende el uso de un instrumento de medida estandarizado para la evaluación del mismo. ![]() Confirmatory factor analysis was carried out using as fit indices: the χ²/df, the Comparative Fit Index (CFI), the Goodness of Fit Index (GFI) and the Root Mean Square Error of Approximation (RMSEA). The Portuguese version was completed in 2009, on the internet, by 958 Brazilian and 556 Portuguese university students from the urban area. The face validity involved the participation of a multidisciplinary team. To perform a cross-cultural adaptation of the Portuguese version of the Maslach Burnout Inventory for students (MBI-SS), and investigate its reliability, validity and cross-cultural invariance.
