The relationship between sleep quality and occupational identity among psychiatric night shift nurses

Psychiatric night-shift nurses generally exhibited poor sleep quality, and the total PSQI score showed a significant negative correlation with the total OIS score. Key factors influencing sleep quality include night shift frequency, sleep quality before and after shifts, as well as lifestyle factors such as daily diet and regular exercise, and occupational identity. Therefore, nursing managers should prioritize sleep health management by optimizing schedules, promoting healthy lifestyle habits, and enhancing occupational identity to improve job stability.
