Abstract
The objectives of this study were to validate the Maslach Burnout Inventory - General Survey
(MBI-GS) and the Oldenburg Burnout Inventory (OLBI), to determine the construct equivalence
and item bias of these instruments for employees in an earthmoving equipment industry in South
&ca of different language groups, to determine the correlation between the MBI-GS and the
OLBI, and to investigate the relationship between burnout and various demographic
characteristics. A random sample of 326 employees in an earthmoving equipment industry of
eight provinces in South Africa was taken. The MBI-GS, the OLBI and a biographical
questionnaire were used as measuring instruments. Cronbach alpha coefficients, inter-item
correlation coefficients, Pearson product-moment correlation coefficients and exploratory factor
analysis were used to analyse the data
The results showed that three factors of the MBI-GS and two factors of the OLBI exist for
different language groups. Exploratory factor analysis with target rotations confirmed the
construct equivalence of the three factors of the MBI-GS and the two factors for the OLBI for
different language groups. No evidence was found for uniform or non-uniform bias of the items
of the MBI-GS or the OLBI for different language groups. Results indicated that no differences
with respect to levels of burnout exist between various demographic characteristics.
Recommendations were made for further research.
