这项初步研究考察了睡眠剥夺对主观和客观的困倦和情绪测量以及精神运动警觉性表现的影响之间的关系。在实验室适应一晚后，健康的年轻人在受控的实验室条件下被随机分配到完全睡眠剥夺一晚（SD组，n=15）或正常睡眠一晚（非SD组，n=14）。第二天，测量主观情绪和困倦报告、客观困倦（多次睡眠潜伏期测试和瞳孔直径自发振荡，PUI）、情感反应/调节（瞳孔对情绪图片的扩张反应）和精神运动警觉性表现（PVT）。睡眠剥夺对所有三个领域（情绪、嗜睡和警惕性）都有显著影响，在9项结果测量中，有8项存在显著的组间差异。在整个样本和SD组中进行的探索性因素分析显示，结果聚集在三个正交维度上，反映了测量方法：嗜睡和情感反应/调节的生理测量，嗜睡和情绪的主观测量，以及警觉性表现。嗜睡和对睡眠剥夺的情感反应是相关的（尽管客观和主观测量是分开的）。PVT表现也独立于嗜睡和影响结果。这些发现表明，客观和主观措施代表不同的实体，不应该假设是等同的。通过将情感结果纳入实验性睡眠剥夺研究，可以评估睡眠缺失对情感功能的影响及其与其他神经行为领域的关系。
This pilot study examined the relationships between the effects of sleep deprivation on subjective and objective measures of sleepiness and affect, and psychomotor vigilance performance. Following an adaptation night in the laboratory, healthy young adults were randomly assigned to either a night of total sleep deprivation (SD group; n=15) or to a night of normal sleep (non-SD group; n=14) under controlled laboratory conditions. The following day, subjective reports of mood and sleepiness, objective sleepiness (Multiple Sleep Latency Test and spontaneous oscillations in pupil diameter, PUI), affective reactivity/regulation (pupil dilation responses to emotional pictures), and psychomotor vigilance performance (PVT) were measured. Sleep deprivation had a significant impact on all three domains (affect, sleepiness, and vigilance), with significant group differences for eight of the nine outcome measures. Exploratory factor analyses performed across the entire sample and within the SD group alone revealed that the outcomes clustered on three orthogonal dimensions reflecting the method of measurement: physiological measures of sleepiness and affective reactivity/regulation, subjective measures of sleepiness and mood, and vigilance performance. Sleepiness and affective responses to sleep deprivation were associated (although separately for objective and subjective measures). PVT performance was also independent of the sleepiness and affect outcomes. These findings suggest that objective and subjective measures represent distinct entities that should not be assumed to be equivalent. By including affective outcomes in experimental sleep deprivation research, the impact of sleep loss on affective function and their relationship to other neurobehavioral domains can be assessed.
