Abstract
This research examines the construct validity of Schaufeli, Leiter, Maslach, and Jackson's (1996) general burnout measure, the Maslach Burnout Inventory-General Survey (MBI-GS). Whereas burnout is traditionally defined and measured in terms of a phenomenon occurring among workers who work with people, the MBI-GS is intended for use outside the human services. The authors first address the internal validity of the MBI-GS using data from two Dutch samples (179 software engineers and 284 university staff members). Confirmatory factor analysis revealed that the distinction among the three subscales of the MBI-GS was retained. To examine external validity, these subscales were then related to selected work characteristics. Based on conservation of resources theory, differential patterns of effects were predicted among the correlates and the three burnout subscales. Expectations were largely supported, suggesting that the meaning of the three subscales is quite different. These results largely replicate findings obtained in similar studies on the validity of the contactual version of the MBI.
