This study attempted to provide occupational health professionals with an empirical basis for identifying and selecting specific occupations for further research into the relationship between job stress and worker health. Specifically, this involved an examination of the admission records of community mental health centers throughout one state (Tennessee) to determine the incidence rate of diagnosed mental health disorders for 130 major occupations (i.e., occupations employing 1,000 or more workers in the state). These occupations were then rank-ordered by incidence rate to provide a general scheme for evaluating the relative frequency of mental health disorders among the select occupations. The results indicated a disproportionate incidence of mental health anomalies among the hospital/health care professions. Some tentative explanations of this finding are presented, and suggestions are made for future research efforts.
