Abstract：
Shift work is a recognized work pattern for nurses worldwide. The disruption of shift workers\' biological clocks usually leads to sleep disorders and affects their awareness at work. Eveningness and occupational stress might be effective in causing burnout syndrome. Therefore, this study aimed to evaluate the chronotype, job burnout and perceived stress among Chinese tertiary hospital nurses, and understand the predictors of circadian rhythm in this group. Between July and September 2020, 23 hospitals were randomly selected from 113 tertiary hospitals in Hunan Province. Twenty-five percent of the nurses working in each hospital were targeted for selection. 28.1% and 17.6% of nurses reported eveningness type and morningness type, respectively. The scores for emotional exhaustion, depersonalization, and perceived stress of eveningness nurses were higher than those of morningness counterparts. Eveningness nurses also reported a lower sense of personal accomplishment. Risk factors of eveningness included being under 30 years old, never exercising, having the stressors of late-night shifts and career development, higher levels of emotional exhaustion, sleep latency, sleep duration, and hypnotic use. Shifts may be unavoidable for nurses, nevertheless, understanding the predictors and related factors of chronotype for nurses is necessary for nursing educators and managers to develop a reasonable shift system and appropriate measures to assist nurses in adjusting their work.
摘要：
轮班工作是全世界公认的护士工作模式。轮班工人生物钟的中断通常会导致睡眠障碍，并影响他们在工作中的意识。平均度和职业压力可能会导致职业倦怠综合征。因此,这项研究旨在评估时间类型，中国三级医院护士的职业倦怠和感知压力，并了解该组昼夜节律的预测因素。2020年7月至9月，从湖南省113家三级医院中随机抽取23家医院。在每家医院工作的护士中有25％是有目标的。28.1%和17.6%的护士报告了晚上型和早晨型，分别。情绪疲惫的分数，去个性化,晚上护士的感知压力高于早上护士。Eveninging护士还报告了较低的个人成就感。晚上的危险因素包括30岁以下，从不锻炼,夜班和职业发展的压力源，更高水平的情绪疲惫，睡眠潜伏期，睡眠持续时间,催眠的使用。对于护士来说，轮班可能是不可避免的，然而，了解护士时间型的预测因素和相关因素是护理教育者和管理者制定合理的轮班制度和适当的措施以协助护士调整工作的必要条件。
