Job stress in the health professions: a study of physicians, nurses, and pharmacists.

While considerable research has been devoted to job stress within individual health professions, little information has been available for comparing the sources or levels of stress among different groups of health professionals. To bridge that knowledge gap, the Health Professions Stress Inventory (HPSI) was administered via a mail questionnaire to 291 primary care physicians, 379 registered nurses, and 387 pharmacists randomly selected from across the United States. Mean stress scores on the HPSI were significantly different for all three professions, with nurses reporting the greatest levels of stress. Frequency of exposure to individual stressful job situations also differed significantly among the professional groups. While exploratory in nature, the results of this research emphasize the interprofessional differences that must be considered when considering the management of job stress in the health care system.
