Psychometric properties of the "Spanish Burnout Inventory" (SBI): Adaptation and validation in a Portuguese-speaking sample

Introduction. - Teaching and nursing are two of the most stressful occupations. The Maslach Burnout Inventory (MBI) has some limitations that require using it with caution out of the American and Anglo-Saxon context. To address the problems associated with the MBI was developed the Spanish Burnout Inventory (SBI). Objective. - This study was designed to assess the psychometric properties of the Portuguese version of the SBI. Method. - The sample consisted of 211 teachers and 133 nurses from Portugal. The psychometric properties were examined through the following analyses: confirmatory factor analysis (CFA), reliability (Cronbach's alpha), and concurrent validity with the MBI. Results. - The four-factor model obtained an adequate data fit for the sample. The Cronbach's alpha coefficient was adequate for the four scales of the instrument. Results supported the concurrent validity. Conclusion. - As a whole, results show that the four-factor model of the SBI possesses adequate psychometric properties for the study of burnout in the Portuguese cultural context.
