A scale designed to assess various aspects of the burnout syndrome was administered to a wide range of human services professionals. Three subscales emerged from the data analysis: emotional exhaustion, depersonalization, and personal accomplishment. Various psychometric analyses showed that the scale has both high reliability and validity as a measure of burnout. Since the publication of this article in 1981, more extensive research was done on the MBI, which resulted in some modifications of the original measure. The present article has been re-edited to reflect those modifications. However, it does not include other new additions (which are contained in the MBI Manual distributed by the publisher, Mind Garden).
