![]() This cross-sectional survey showed that psychological capital has significant mediation effects on the relationship between occupational stressors and insomnia. Results: The study findings revealed that work settings, decision latitude ( r = −0.25, p < 0.001), psychological job demand ( r = 0.15, p < 0.001), social support ( r = −0.31, p < 0.001), and psychological capital ( r = −0.40, p < 0.001) were differentially associated with insomnia experiences. Questionnaires were used to obtain data on demographic variables, psychological capital, occupational stressors, and insomnia. A cross-sectional stratified sampling method was used to recruit 720 participants from a tertiary hospital in Jinan, Shandong province, located in the east of China, from June to August 2019. Methods: The Strengthening the Reporting of Observational Studies in Epidemiology statement was referred to conduct the study. Objective: This study aimed to explore the mediating effect of psychological capital on occupational stressors and insomnia among Chinese nurses. ![]() Psychological capital, the positive psychological strength of an individual, has been widely used in previous reports as a mediating variable between occupational stress and adverse psychological problems. Therefore, it is necessary to discuss the complex mediating variables in the relationship between occupational stress and insomnia in nurses in order to find different ideas to address the problem of insomnia caused by occupational stress. As an external feature of the role of a nurse, occupational stress is difficult to alter in a short period of time. Over the past 30 years, a large number of epidemiological surveys have shown that insomnia in nurses is associated with occupational stress. Insomnia not only damages the physical and mental health of nurses, but also reduces their productivity and quality of care, ultimately affecting patient care. 3Department of Pediatrics, The First Affiliated Hospital of Air Force Military Medical University, Xi’an, Chinaīackground: Nurses have a high incidence of insomnia. ![]() 2School of Nursing, The Fourth Military Medical University, Xi’an, China. ![]()
