Burnout is considered to be a long-term reaction to occupational stress. It is characterized by emotional exhaustion, depersonalization, and diminished personal accomplishment. The most widely used instrument to measure burnout is the Maslach Burnout Inventory (MBI), developed by Maslach and Jackson (1986). From this instrument, Schaufeli and van Dierendonck (1995a) developed a somewhat modified Dutch version: the MBI-NL. Burnout among dentists has hardly been studied. Since the professions that the MBI-NL was developed upon are quite different from dentistry, the aim of this study was to test the three-factor structure of the MBI-NL against alternative structures among dentists. Both principal components analysis (PCA) and confirmatory factor analysis (CFA) were examined in a representative sample of 709 Dutch general dental practitioners (75 per cent response rate). The three-factor structure shows the best fit to the underlying data, while other psychometric qualities are very satisfactory. It is concluded that the three-factor structure of the MBI-NL is superior to alternative structures, and that the MBI-NL is a highly suitable instrument to measure burnout among dentists.
