Factorial validity and consistency of the MBI-GS across occupational groups in Norway.

University of TromsoThe present study tested the factorial validity of the Maslach BurnoutInventory–General Survey (MBI-GS) among 694 participants from 4 differ-ent occupational groups. Confirmatory factor analyses of the total sample, aswell as multigroup analyses and analyses of each of the 4 occupationalgroups separately, indicated that the original 3-factor model of the MBI-GSprovided a good fit to the data. Internal consistencies of the subscales of theMBI-GS were acceptable, and test–retest reliability indicated relative sta-bility of scores over a 6-month interval. These results indicate that theproposed 3-factor structure of the MBI-GS, based on 16 items, can bereplicated in the total sample as well as across different occupational groupsin Norway.
