航空、军事、警察和卫生保健人员对睡眠限制和工作安排的操作影响特别感兴趣，因为疲劳相关的错误可能造成严重后果。大多数检查睡眠不足或昼夜节律操纵影响的研究都是在受控的实验室环境中进行的，样本量很小。本研究通过对健康警察学院新兵的实地调查，考察了前一晚睡眠时间与精神运动警觉性任务表现之间的关系是否能够可靠地检测出来。受试者（N = 189）医学和精神健康。用腕部活动记录仪评估7天的睡眠-觉醒活动。受试者在警察学院工作日前后和休息日的相应时间在个人数字助理（PDA）设备上执行5分钟的精神运动警戒任务（PVT）。使用混合效应逻辑回归来估计在7天的现场测试中，PVT出现>= 1失效的概率作为前一晚睡眠时间的函数。对1082个夜晚的睡眠时间进行了有效的估计。在测试前一晚，睡眠失误的概率每小时下降3.5%。在保持睡眠时间不变的情况下，自觉醒以来发生睡眠失误的总体概率每小时下降0.9%。感知到的压力与睡眠时间或表现下降的可能性无关。这些发现证明了在大型实地研究中检测睡眠和昼夜节律对认知表现的影响的可行性。这些发现对警察白天的工作有影响。(作者通信：Thomas。Neylan@ucsf.edu)
Aviation, military, police, and health care personnel have been particularly interested in the operational impact of sleep restriction and work schedules given the potential severe consequences of making fatigue-related errors. Most studies examining the impact of sleep loss or circadian manipulations have been conducted in controlled laboratory settings using small sample sizes. This study examined whether the relationship between prior night sleep duration and performance on the psychomotor vigilance task could be reliably detected in a field study of healthy police academy recruits. Subjects (N = 189) were medically and psychiatrically healthy. Sleep-wake activity was assessed with wrist actigraphy for 7 days. Subjects performed the psychomotor vigilance task (PVT) for 5 min on a personal digital assistant (PDA) device before and after their police academy workday and on comparable times during their days off. Mixed-effects logistic regression was used to estimate the probability of having >= 1 lapse on the PVT as a function of the previous night sleep duration during the 7 days of field testing. Valid estimates of sleep duration were obtained for 1082 nights of sleep. The probability of a lapse decreased by 3.5%/h sleep the night prior to testing. The overall probability of having a lapse decreased by 0.9%/h since awakening, holding hours of sleep constant. Perceived stress was not associated with sleep duration or probability of performance lapse. These findings demonstrate the feasibility of detecting sleep and circadian effects on cognitive performance in large field studies. These findings have implications regarding the daytime functioning of police officers. (Author correspondence: Thomas. Neylan@ucsf.edu)
