背景/目的：慢性疲劳综合征（CFS）的核心症状之一是睡眠不清醒和睡眠质量差的主观感觉。据我们所知，这种感知是否可以在匹兹堡睡眠质量指数（PSQI）的标准化问卷中表达，在CFS中从未有过记录。此外，主观疲劳，PSQI，情感症状和客观参数，如睡眠效率的相关性在文献中描述得很少。研究方法：采用横断面研究范式，我们研究了28名“纯”CFS患者（无原发性睡眠和精神障碍）与年龄和性别匹配的健康对照组相比的主观指标，如PSQI、疲劳严重程度量表评分和由汉密尔顿抑郁和焦虑量表评定的情感症状强度，以及由多导睡眠图测量的客观睡眠质量参数。结果：CFS患者PSQI主观睡眠质量明显低于健康对照组。相比之下，客观的睡眠质量参数，如睡眠效率指数（SEI）或慢波睡眠量没有显着差异。CFS患者的主观睡眠质量与疲劳程度呈相关趋势，与情感症状强度无关。结论：我们的研究结果表明，睡眠质量的误解存在于CFS或潜在的夜间神经生理紊乱参与CFS的非恢复性感觉不表示的睡眠变量，如SEI或睡眠阶段的分布和比例。版权所有（c）2007 S.

Background/Aims: One of the core symptoms of the chronic fatigue syndrome (CFS) is unrefreshing sleep and a subjective sensation of poor sleep quality. Whether this perception can be expressed, in a standardized questionnaire as the Pittsburgh Sleep Quality Index (PSQI), has to our knowledge never been documented in CFS. Furthermore, correlations of subjective fatigue, PSQI, affective symptoms and objective parameters such as sleep efficiency are poorly described in the literature. Methods: Using a cross-sectional paradigm, we studied subjective measures like PSQI, Fatigue Severity Scale scores and intensity of affective symptoms rated by the Hamilton Depression and Anxiety scales as well as objective sleep quality parameters measured by polysomnography of 28 'pure' (no primary sleep and no psychiatric disorders) CFS patients compared to age- and gender-matched healthy controls. Results: The PSQI showed significantly poorer subjective sleep quality in CFS patients than in healthy controls. In contrast, objective sleep quality parameters, like the Sleep Efficiency Index (SEI) or the amount of slow-wave sleep did not differ significantly. Subjective sleep quality showed a correlation trend with severity of fatigue and was not correlated with the intensity of affective symptoms in CFS. Conclusion: Our findings indicate that a sleep quality misperception exists in CFS or that potential nocturnal neurophysiological disturbances involved in the non-recovering sensation in CFS are not expressed by sleep variables such as the SEI or sleep stage distributions and proportions.
