This article investigates the psychometric properties of a mainstream burnout measure dedicated to teachers: the Maslach Burnout Inventory-Educators Survey (MBI-ES). The study used data gathered from a random sample of 1,206 primary school teachers in Poland to verify the construct validity of the MBI-ES. Eight alternative measurement models suggested in the literature were tested using confirmatory factor analysis. Contrary to many previous studies, this study did not support the oblique three-factor structure of the MBI-ES. A bifactor model with one general Burnout factor and three specific orthogonal factors of personal accomplishment, depersonalization, andemotional exhaustion showed best fit to the data. Additional analyses supported the measure’s essential unidimensionality. The results yield theoretical implications for construct reconceptualization and practical guidelines for researchers and practitioners.
