Psychological burnout has a detrimental impact on workers in the human service field, and variables contributing to the burnout process need to be explored. In order to examine the relationships between burnout and four commitment dimensions (commitment to a theory, to agency philosophy, to a particular job, and to client service), 47 professionals (37 females and 10 males) serving the developmentally disabled in a day treatment program completed questionnaires. Burnout was measured by the Maslach Burnout Inventory (MBI). Results showed that in an agency where the staff shared no strong ideological theory (which is felt by researchers C. Cherniss and D. Krantz to increase commitment and reduce burnout), reduced levels of burnout were correlated with commitment to the agency's philosophy and objectives, and to one's job classification. There was no isgnificant correlation between burnout and commitment to clients. (BH)
