The objectives of this study are to assess the psychometric properties of an adapted version of the Maslach Burnout Inventory-General Survey (MBI-GS) for academic staff in South African higher education institutions and to investigate differences between the burnout levels of different demographic groups. A survey design was used, with stratified random samples (N = 595) taken of academics in six South African universities. Exploratory factor analysis with target rotations resulted in a three-factor model of burnout, consisting of Exhaustion, Mental Distance and Professional Efficacy. The scales showed acceptable internal consistencies and construct equivalence for two language groups. Practically significant differences were found in the burnout levels of academics with regard to their age. (Contains 4 tables.)
