Shift work is common yet does not always result in , fifth edition (DSM-5)-defined shift work sleep disorder (SWD). This study reports on the reliability and validity of the DSM-5 informed Shift Work Disorder Index (SWDI), the presence of probable SWD in nurses, and demographic, sleep, and psychosocial correlates.
Nurses (n = 454) completed the SWDI, psychosocial, and demographic questionnaires. Of the sample, n = 400 completed 14 days of sleep diaries, actigraphy, and additional questionnaires.
The global SWDI demonstrated excellent internal consistency (α = .94), as well as good convergent and divergent validity in the nurse sample. Thirty-one percent of nurses were past-month shift workers, with 14% (ie, 44% of shift workers) having probable SWD based on SWDI. Nurses who worked shift work and/or met SWD criteria were more likely to be younger and unmarried and less likely to have children than day workers and reported greater evening chronotype, insomnia, nightmares, and sleep-related impairment, greater depression, anxiety, posttraumatic stress, and perceived stress symptoms, as well as later and more variable sleep midpoint (actigraphy), shorter sleep duration (actigraphy, diaries), and lower sleep efficiency (diaries).
The SWDI is an efficient and valid self-report assessment of DSM-5-defined SWD. Shift work and/or SWD were prevalent and associated with worse sleep and psychosocial health, particularly among nurses with probable SWD.

倒班工作很常见，但并不总是导致符合《精神障碍诊断与统计手册》第五版（DSM-5）定义的轮班工作睡眠障碍（SWD）。本研究报告了 DSM-5 知情的轮班工作障碍指数（SWDI）的可靠性和有效性、护士中可能存在的 SWD 以及人口统计学、睡眠和心理社会相关因素。
护士（n=454）完成了 SWDI、心理社会和人口统计学问卷。在样本中，n=400 完成了 14 天的睡眠日记、活动记录仪和其他问卷。
全球 SWDI 表现出优异的内部一致性（α=0.94），并且在护士样本中具有良好的收敛和区分效度。31%的护士是过去一个月的轮班工人，其中 14%（即 44%的轮班工人）根据 SWDI 患有可能的 SWD。从事轮班工作和/或符合 SWD 标准的护士比白班工人更年轻、未婚、子女较少，并且表现出更大的夜间生物钟、失眠、噩梦和与睡眠相关的障碍、更大的抑郁、焦虑、创伤后应激和感知压力症状，以及更晚和更可变的睡眠中点（活动记录仪）、更短的睡眠时间（活动记录仪、日记）和更低的睡眠效率（日记）。
SWDI 是一种有效的 DSM-5 定义的 SWD 自我报告评估工具。轮班工作和/或 SWD 很常见，与睡眠和心理健康状况较差有关，尤其是在可能患有 SWD 的护士中。
