Sleep laboratory studies of patients complaining of insomnia have demonstrated discrepancies between subjective reports and electroencephalograph (EEG)-recorded measures. In our research studies on sleeping aids, 60% of the self-described poor sleepers who reported usual sleep latencies of at least 45 min did not meet the laboratory qualification criterion of a 30-min or longer sleep latency. To learn to predict who would qualify for our studies, we compared 30 laboratory-qualified poor sleepers (QPS) with 30 laboratory-disqualified poor sleepers (DPSs) on subjective report, mood, and all-night sleep laboratory variables. QPSs had significantly lower sleep efficiency and total sleep time in the laboratory, but these differences were due to the longer sleep latencies (50.7 +/- 27.8 min vs. 15.2 +/- 6.1 min) of the QPS group. QPSs and DPSs differed significantly in their morning estimates of their laboratory sleep latencies; as a group, QPSs gave an accurate estimate (51.6 +/- 27.8 min), but DPSs were significantly more likely to exaggerate their sleep latencies. Although we did not identify ways of predicting which poor sleepers would show sleep-onset insomnia in the sleep laboratory, we did find that, in this young, healthy population, there are poor sleepers who give an accurate report of a rather severe sleep-onset insomnia.
对主诉失眠的患者进行的睡眠实验室研究表明，主观报告与脑电图（EEG）记录的测量结果之间存在差异。在我们关于助眠药物的研究中，60%自称睡眠质量差且报告通常入睡潜伏期至少为45分钟的人，未达到实验室规定的入睡潜伏期30分钟或更长的标准。为了了解如何预测哪些人符合我们研究的条件，我们将30名实验室合格的睡眠质量差者（QPS）与30名实验室不合格的睡眠质量差者（DPS）在主观报告、情绪和整夜睡眠实验室变量方面进行了比较。QPS在实验室中的睡眠效率和总睡眠时间显著更低，但这些差异是由于QPS组的入睡潜伏期更长（50.7±27.8分钟对15.2±6.1分钟）。QPS和DPS在对实验室入睡潜伏期的早晨估计上有显著差异；作为一个群体，QPS给出了准确的估计（51.6±27.8分钟），但DPS更有可能夸大他们的入睡潜伏期。虽然我们没有找到预测哪些睡眠质量差的人在睡眠实验室会出现入睡失眠的方法，但我们确实发现，在这个年轻、健康的人群中，有一些睡眠质量差的人对相当严重的入睡失眠给出了准确的报告。
