Analysing the effect of social jetlag on burnout among shift nurse using a chained mediation model.

The purpose of the present research is to explore the relationship between social jetlag and burnout among Chinese shift nurses. Furthermore, we seek to demonstrate how perceived stress and sleep quality play as chain mediators in this relationship. A cross-sectional study. There are 429 Chinese shift nurses data records included through one-on-one format using the subjects' sociodemographic information, the Munich Chronotype Questionnaire for shift workers (MCTQshift), the Chinese version of the 14-item Perceived Stress Scale (CPSS-14), the Pittsburgh Sleep Quality Index (PSQI), and the Chinese version of Maslach Burnout Inventory-General Survey. The positive correlations are found between social jetlag and burnout among Chinese shift nurses; perceived stress and sleep quality, respectively, play a partial mediating role in this relationship. Furthermore, perceived stress and sleep quality play a chain mediating role between social jetlag and burnout. These findings contribute to understanding the impact mechanism of social jetlag on shift nurses' burnout and provide a theoretical foundation for nurses managers to develop programs designed for reducing the burnout that affects shift nurses.
