Association Between Sleep Quality and Job Stress Among Night-Shift Nurses in Critical Care Units: A Cross-Sectional Study

Objective: The current study aimed to investigate the association between sleep quality and job stress among night-shift critical care nurses, while examining how socio-demographic factors influence these issues within the working hours system in effect. Methods and Materials: A cross-sectional study was conducted with the participation of 178 night-shift critical care nurses working in three randomly selected governmental healthcare facilities. Participants were selected via the availability sampling method. Demographic characteristics, Pittsburgh Sleep Quality Index (PSQI), and the Expanded Nurses Stress Scale (ENSS) were collected. Data collection took place from September 12, 2024, to October 29, 2024. SPSS 27 was used for data analysis. Findings: Among the 178 nurses, 62.9% were classified as having poor sleep quality, while 37.1% had good sleep quality. A significant proportion of participants (51.1%) reported high job stress levels. The results revealed a significantly positive correlation between sleep quality and job stress. Conclusion: The study identifies a strong association between sleep quality and job stress among night-shift critical care nurses. Key demographic factors influencing these outcomes were highlighted, offering insights for targeted interventions.
