A model of managerial burnout was examined among 148 human service supervisors and managers. The findings suggest that emotional exhaustion plays a central mediating role in the burnout process. Social support and direct control were associated with exhaustion through role stress. Job and life satisfaction, and time spent with clients and subordinates were also related to exhaustion. In turn, exhaustion was related to depersonalization, professional commitment, and turnover intentions. An expected reciprocal relation between exhaustion and helplessness was not found, as the former had only a weak impact on the latter. Implications for stress coping are discussed.
