The Bifactor Model of the Maslach Burnout Inventory–Human Services Survey (MBI-HSS)—An Alternative Measurement Model of Burnout

Authors


Abstract

The purpose of the present study was to examine the construct validity of the Hungarian language version of the Maslach Burnout Inventory–Human Services Survey (MBI-HSS). A sample of 653 healthcare professionals (420 physicians and 233 nurses and nursing assistants) completed the MBI-HSS. A series of confirmatory factor analyses showed that a hierarchical bifactor model including a global burnout factor and three specific factors of emotional exhaustion, depersonalization and reduced personal accomplishment had the closest fit to the data, compared with an alternative second-order three-factor hierarchical model as well as to non-hierarchical one-factor, two-factor, three-factor, four-factor and five-factor models. However, only the global burnout factor and the specific personal accomplishment factor explained a considerable unique proportion of variance in observed scores. Our study confirms the validity of the MBI-HSS and suggests an alternative structural model, which may contribute to further understanding of the burnout construct.
