Association between work role stressors and sleep quality.

ABSTRACT

Background: Work-related stressors are associated with low sleep quality. However, few studies have reported an association between role stressors and sleep quality. Aims: To elucidate the association between role stressors (including role conflict and ambiguity) and sleep quality. Methods: Cross-sectional study of daytime workers whose sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Work-related stressors, including role stressors, were assessed using the Generic Job Stress Questionnaire (GJSQ). The association between sleep quality and work-related stressors was investigated by logistic regression analysis. Results: A total of 243 participants completed questionnaires were received (response rate 71%); 86 participants reported poor sleep quality, based on a global PSQI score ≥6. Multivariable logistic regression analysis revealed that higher role ambiguity was associated with global PSQI scores ≥6, and that role conflict was significantly associated with sleep problems, including sleep disturbance and daytime dysfunction. Conclusions: These results suggest that high role stress is associated with low sleep quality, and that this association should be considered an important determinant of the health of workers.
