Abstract：Objective To understand the sleep status and its influencing factors, as well as the correlation between sleep and job burnout in psychiatric nurses.Methods A total of 200 psychiatric nurses were investigated by the Pittsburgh Sleep Quality Index(PSQI), Epworth sleepiness scale(ESS) and Maslach Burnout Inventory-General Survey(MBI-GS). Logistic regression analysis was adopted to determine the influencing factors of nurses' sleep disorders.Results The total score of PSQI of the involved nurses was higher than normal population, and the difference was statistically significant(P<0.05), and 32.5％ of nurses had sleep problems. ESS results showed that most nurses had lethargy. The total score of ESS was positively correlated with sleep quality, sleep disorders, daytime dysfunction and PSQI total score. There was no statistically significant difference in the total score of PSQI, ESS and MBI-GS between the two groups of night shift nurses and no night shift nurses in nearly one month(P<0.05). The scores of the sleep quality, sleep time, hypnotic drugs, daytime dysfunction and the total score of PSQI were positively correlated with the score of emotional exhaustion and removal of personalization dimensions. However, there was no correlation between personal accomplishment and the total score, as well as the element scores of the PSQI. In addition, there was no correlation between job burnout scores and the total score of ESS. Logistic regression analysis showed that age and nursing age were the main risk factors affecting sleep of psychiatric nurses. The risk of sleep problems in nurses with intermediate professional titles was much lower than that of primary nurses.Conclusions Psychiatric nurses have sleep and sleepiness problems. The quality of sleep has significant interaction with job burnout. Sleep disorders not only affect physical and mental health, but also lead to the decreased quality of care. The main risk factors of affecting psychiatric nurses' sleep are age and nursing age. Compared with the nurses with primary professional titles, the nurses with intermediate were less likely to have sleep problems.
