Testing for the factorial validity of the MBI: results for a multiocupational sample.

This study was designed to assess the structure of the Maslach Burnout Inve ntory (MBI) for 559 professionals from diverses occupational services secto rs (health, education, police, hotels and banks). Responses were factor ana lysed using principal components and Varimax rotation. Exploratory factor a nalysis offered four factors with eigenvalues exceeding unity. Items of Emo tional Exhaustion loaded on Factor I, items of Depersonalisation on Factor II, and items of Personal Accomplishment on both Factor III and Factor IV. A second factor analysis was carried out with a specification to extract th ree factors. This factor analysis showed a factor structure consistent with the original. However, Items 6 and 16 loaded on Emotional Exhaustion and D epersonalisation dimensions, and item 12 on Emotional Exhaustion and Person al Accomplishment dimensions. As a whole, results show that the MBI appears to be valid and reliable for Spanish professionals.
