Abstract
Burnout has been considered important to understanding the well-being of social workers and the quality of the services they render. Despite the ample international usage of the Maslach Burnout Inventory, its psychometric properties have come into question and alternative models of measuring the inventory have been suggested. The purpose of this study was to examine the psychometric properties and the applicability of a Spanish version of the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) in an incidental sample of 947 social workers. Three alternative models of the MBI-HSS were tested for the purpose of identifying the most suitable model for measuring burnout in Spain. The confirmatory factor analysis supported the theory that the model of three correlated factors was superior to alternative models of one and two factors. The structure of three factors (emotional exhaustion, depersonalization, and personal accomplishment) and 19 items showed the best adjustment and a suitable internal consistency of the dimensions of the MBI-HSS. These findings demonstrate that the MBI-HSS has validity and reliability acceptable for measuring burnout in social workers, providing valuable information to the managers of social services in order to reduce burnout among social workers. The limitations of the study and recommendations for future investigation are emphasized.
