Sleep quality mediates the relationship between work-family conflicts and the self-perceived health status among hospital nurses.

Abstract

To examine the effects of work-family conflicts and sleep quality on the self-perceived health status and the mediating effect of sleep quality on the relationship between work-family conflicts and self-perceived health status among hospital nurses. Studies related to hospital nurses' work-family conflicts, sleep quality and health status are noteworthy but limited. A total of 575 hospital nurses in Taiwan were recruited. Data were collected using the work-family conflicts Scale, Chinese Pittsburgh Sleep Quality Index and Chinese Health Questionnaire. Independent t-tests, chi-squared tests, multivariate linear regression analyses and the Sobel test were used for analysis. Fifty-six per cent of all subjects reported having good health. Significantly more nurses with good sleep reported good health than those with poor sleep (84.2% vs. 44.9%, p<0.0001). The difference in overall work-family conflict scores between the good health group and poor health group was significant (37.3±12.7 vs. 46.3±14.3, p<0.0001). The correlation between overall work-family conflicts and the self-perceived health status was indirect, and sleep quality was a mediator (Sobel test: 5.007, p<0.001). Work-family conflicts and poor sleep quality of hospital nurses were associated with poor health. Shift work influences the sleep quality, which mediates the correlation between work-family conflicts and self-perceived health status. Hospital administrators should be aware of these stressful factors and the health of hospital nurses can be better promoted.
