目的：本研究的目的是评估客观和主观的睡眠质量之间的关系和客观和主观评价的认知表现的老年人患有慢性失眠症（使用或不使用苯二氮卓类药物，BZ）或自我报告良好的睡眠者。研究方法：对三组55岁及以上的参与者进行了评估：20名长期使用BZ的失眠患者，20名无药物失眠患者和20名睡眠良好者。测量客观睡眠（PSG）和主观睡眠（睡眠日记，SD）。评估了认知表现（注意力/集中力、言语/视觉记忆、执行功能和精神运动速度）的客观指标和日常表现的主观感知。结果如下：相关性分析显示，客观和主观的日间表现的措施是差异相关的睡眠质量的三组。客观的良好睡眠与良好睡眠者和无药物个体的更好认知表现有关。另一方面，睡眠良好的印象与使用BZ的良好睡眠者和慢性失眠患者的更好认知表现有关。结论：白天的表现和睡眠质量是相关的，但对于一个好睡眠者，一个没有治疗的失眠症患者，或者一个使用BZ来缓解睡眠困难的人来说是不同的。(C)2003年爱思唯尔科学公司All rights reserved.
Objective: The objective of the present study was to evaluate the relationship between objective and subjective sleep quality and objective and subjective evaluation of cognitive performance in older adults suffering of chronic insomnia (using or not benzodiazepines, BZs) or self-reported good sleepers. Methods: Three groups of participants 55 years and older were evaluated: 20 insomnia sufferers using BZs chronically, 20 drug-free insomnia sufferers and 20 good sleepers. Objective sleep (PSG) and subjective sleep (sleep diaries, SD) were measured. Objective measures of cognitive performance (attention/concentration, verbal/visual memory, executive function and psychomotor speed) and subjective perception of daily performance were evaluated. Results: Correlational analysis revealed that objective and subjective measures of daytime performance are differentially related to sleep quality for the three groups. An objective good night of sleep is associated with better cognitive performance in good sleepers and drug-free individuals. On the other hand, the impression of having slept well is related to better cognitive performance in good sleepers and chronic insomnia sufferers using BZs. Conclusion: Daytime performance and sleep quality are related, but differently so for a good sleeper, an insomnia sufferer without treatment, or one using BZs to alleviate sleep difficulties.
