Background: Job burnout has become an increasing prevailing phenomenon among nurses in both developed and developing countries. There is a paucity of research exploring the effect of perceived stress (i.e., the level of one’s perception or appraisal of stress rather than objective stressful events) on burnout and no existing literature examining the mediating role of sleep quality in the relationship between perceived stress and job burnout. The objective of the study was to examine the mediating effect of sleep quality in the relationship between perceived stress and job burnout. Methods: Cross-sectional data were collected from a total of 1013 nurses working in 6 public tertiary hospitals in China. The self-administered questionnaire included demographic information, the Maslach Burnout Inventory-General Scale, the Pittsburgh Sleep Quality Index and the Perceived Stress Scale. Hierarchical multiple regression (HMR) analyses were performed to examine the contribution of each covariate to the prediction of job burnout. Structural equation modeling (SEM) was employed to test whether the proposed relationships between variables involved existed. Results: Both perceived stress and poor sleep quality exhibited strong positive associations with job burnout among Chinese nurses. The SEM analysis confirmed the direct pathway from perceived stress to burnout and the indirect pathway mediated by sleep quality. The direct effect of perceived stress on job burnout was found to be statis...
