The relationship of burnout and sources of social support among Turkish school counselors was investigated, and the influences of some sociodemographic variables on burnout were examined. Participants were 214 school counselors who were given the Maslach Burnout Inventory (Maslach & Jackson, 1981), and Sources of Social Support Questionnaires (Haddad, 1998). Pearson correlation coefficients, ANOVA and Scheffe's test were used for data analyses. Results showed significant negative relationships between dimensions of burnout and sources of social support. Also, participants' scores on depersonalization and personal accomplishment varied according to the length of their work experience. However, no relationships were found between dimensions of burnout and gender, age, or marital status. Findings, their implications, limitations of the study and recommendations for future research are discussed.
