Stress and health outcomes: The mediating role of negative affectivity in female health care workers.

The current study explored the interrelationships among occupational stress, family stress, poor physical health, and psychological distress and examined the mediating role of negative affectivity (NA) in the stress and health process. A cross-sectional, nonexperimental design was used and a convenience sample of 271 female health care workers was recruited from northeastern Ohio. Data were collected with a self-reported questionnaire, scanned using Teleform Software, and electronically transferred to the SPSS format. Data analyses were performed in three separate phases: preliminary, measurement model, and structural model analyses (using structural equation modeling). Results suggested that occupational stress had a significant effect on psychological distress, and family stress had a significant impact on both poor physical health and psychological distress. NA partially mediated the effect of occupational stress on psychological distress. The effects of family stress on poor physical health and psychological distress were also partially mediated through NA. The indirect to total effect ratios were 30%, 17.15%, and 28%, respectively.
