The dimensionality of the Maslach Burnout Inventory across small business owners and educators

This study tested the dimensionality of the Maslach Burnout Inventory (MBI) by comparing three factor structures (i.e., a one-factor structure, a thre e-factor structure, and a higher order factor structure) in two diverse sam ples. The comparison of the LISREL measurement models was extended by a ser ies of measurement invariance tests. Additionally, constructs related to bu rnout had a pattern of correlations to the three MBI dimensions that was si milar across the two samples. In aggregate, the analyses suggested that the three-factor structure of the MBI is the most plausible model. By using a sample of small business owners, the current research contributed to existi ng knowledge on the MBI by establishing the dimensionality and generalizabi lity of the MBI beyond human service occupations.
