研究目的：至少15%的全职工作人员是轮班工人。在夜间工作，清晨开始时间以及可变或轮换的时间表对昼夜节律系统提出了挑战，这些变化与不利的健康和安全后果有关。轮班工作障碍（SWD）是一种原发性（昼夜节律）睡眠障碍，表现为白天过度嗜睡和/或与轮班工作时间表相关的失眠，初级保健医生对其认识不足。我们试图开发和验证的问卷调查，以筛选高风险的SWD在轮班workingpopulation.Design：轮班工人完成了26项问卷调查，并进行了评估的睡眠专家（医生）诊断他们为积极或消极的SWD。SWD的医生评估由流程图指导，该流程图操作了SWD的ICSD-2标准。设置：美国的18家睡眠诊所。患者或参与者：311名轮班工人。干预措施：不适用。测量和结果：对问卷中的项目的回答被输入到一系列的判别函数分析中，以确定项目的诊断价值和最少数量的问题，最佳预测值。然后对函数进行交叉验证。最终的4项问卷有89%的阳性预测值和62%的阴性预测值（敏感性= 0.74;特异性= 0.82）。结论：这种轮班障碍筛查问卷可能是适当的，用于在初级保健设置，以帮助诊断社会福利署。
Study Objective: At least 15% of the full-time work force is shift workers. Working during the overnight hours, early morning start times, and variable or rotating schedules present a challenge to the circadian system, and these shifts are associated with adverse health and safety consequences. Shift work disorder (SWD), a primary (circadian rhythm) sleep disorder indicated by excessive daytime sleepiness and/or insomnia associated with a shiftwork schedule, is under-recognized by primary care physicians. We sought to develop and validate a questionnaire to screen for high risk of SWD in a shift working population.Design: Shift workers completed a 26-item questionnaire and were evaluated by a sleep specialist (physician) who diagnosed them as either positive or negative for SWD. The physician assessment of SWD was guided by a flow chart that operationalized the ICSD-2 criteria for SWD.Setting: 18 sleep clinics in the USA.Patients or Participants: 311 shift workers.Interventions: Not applicable.Measurements and Results: Responses to the items in the questionnaire were entered into a series of discrimination function analyses to determine the diagnostic value of the items and the fewest number of questions with the best predictive value. The function was then cross-validated. A final 4-item questionnaire has 89% positive predictive value and 62% negative predictive value (sensitivity = 0.74; specificity = 0.82).Conclusions: This Shiftwork Disorder Screening Questionnaire may be appropriate for use in primary care settings to aid in the diagnosis of SWD.
