目的：研究分布，一致性和相关性的睡眠时间知觉在原发性失眠患者和正常睡眠者跨设置（实验室和家庭）。方法：52名中年和老年失眠患者和49名匹配的正常睡眠者进行了多个晚上的实验室和家庭多导睡眠图（PSG），并提供了同时主观估计他们的睡眠。描述性统计、聚类分析和推理测试被用来检查睡眠时间感知的性质，识别具有独特模式（如感知）的亚组，并探索可能导致这些亚组独特睡眠感知的因素。与以前的研究一致，失眠症患者作为一个群体，比正常睡眠者更倾向于低估他们的睡眠时间，但睡眠时间感知的准确性在每个样本中变化很大。相关性分析显示，每个样本中的研究参与者在估计夜间睡眠时间的准确性方面表现出中等程度的一致性。随后进行聚类分析，以确定亚组的睡眠时间知觉的独特模式产生了四个亚组内的失眠样本和三个亚组内的正常睡眠者样本。虽然睡眠设置显着影响睡眠的看法，一个失眠症的亚组，实验室和家庭的客观-主观的睡眠比较提供了类似的印象，每个亚组的夜间睡眠/清醒的看法的相对准确性。最后，不同模式的亚组差异，注意到在几个常见的心理测量measurements.Conclusions：低估的睡眠时间是不是一个通用的特性，区分所有失眠患者从正常的睡眠者。睡眠环境、个性特征，也许还有体质因素，似乎会影响人们对睡眠和清醒时间的看法。(C)2003年由Elsevier B.

Objective: To examine the distribution, consistency, and correlates of sleep time perceptions in primary insomnia sufferers and normal sleepers across settings (laboratory and home).Methods: Fifty-two middle-aged and older insomnia sufferers and 49 matched normal sleepers underwent multiple nights of laboratory and home polysomnography (PSG) and provided concurrent subjective estimates of their sleep. Descriptive statistics, cluster analyses, and inferential tests were used to examine the nature of sleep time perceptions, identify subgroups with distinctive patterns such as perceptions, and explore factors that may contribute to these subgroups' distinctive sleep perceptions.Results: Consistent with previous studies, the insomnia sufferers, as a group, showed a greater tendency to underestimate the time they slept than did the normal sleepers, but the accuracy of sleep time perceptions varied widely within each sample. Correlational analyses showed that study participants in each sample showed a moderate level of consistency in how accurately they estimated sleep time across nights. Subsequent cluster analyses conducted to identify subgroups with distinctive patterns of sleep time perceptions yielded four subgroups within the insomnia sample and three subgroups within the normal sleeper sample. Although the sleep setting significantly affected sleep perceptions for one insomnia subgroup, both laboratory and home objective-subjective sleep comparisons provided similar impressions regarding the relative accuracy of each subgroup's nocturnal sleep/wake perceptions. Finally, varying patterns of subgroup differences were noted across several common psychometric measures.Conclusions: The underestimation of sleep time is not a generic characteristic that separates all insomnia sufferers from normal sleepers. Sleep setting, personality traits, and perhaps constitutional factors appear to influence perceptions of sleep and wake time duration. (C) 2003 Published by Elsevier B.V.
