AIM
This study examined the mediating effect of circadian rhythm amplitude (LV) and stability (FR) between work stress and sleep quality among Chinese shift-working nurses (SWNs).
DESIGN
A cross-sectional study.
METHODS
Three-hundred and seventy-nine nurses working in shifts were investigated by convenient sampling from six hospitals in Shanghai, China. The mediating effect was analysed using the structural equation model with bootstrapping procedures.
RESULTS
Work stress could directly affect shift nurses' sleep quality and indirectly affect sleep quality through circadian rhythm amplitude and stability. The total indirect effects of work stress on sleep quality accounted for 36.7% of the total effect. The study revealed that poor sleep quality is very common among SWNs, which deserves attention. The mediating effect of the circadian rhythm provides new insights to improve sleep quality, not only by lightening the work stress but also by improving circadian rhythm in SWNs.
目的
本研究旨在探讨中国倒班护士工作压力与睡眠质量之间的中介效应，即昼夜节律幅度（LV）和稳定性（FR）。
设计
横断面研究。
方法
采用便利抽样法，从中国上海的六家医院抽取 379 名倒班护士进行调查。采用结构方程模型和 bootstrap 程序分析中介效应。
结果
工作压力可直接影响倒班护士的睡眠质量，也可通过昼夜节律幅度和稳定性间接影响睡眠质量。工作压力对睡眠质量的总间接效应占总效应的 36.7%。研究表明，SWNs 的睡眠质量普遍较差，值得关注。昼夜节律的中介作用为改善睡眠质量提供了新的思路，不仅可以减轻工作压力，还可以改善 SWNs 的昼夜节律。
