Subjective sleep quality is an individual's subjective sleep feeling, and its effective evaluation is the premise of improving sleep quality. However, people with autism or mental disorders often experience difficulties in verbally expressing their subjective sleep quality. To solve the above problem, this study provides a non-verbal and convenient brain feature to assess subjective sleep quality. Reportedly, microstates are often used to characterize the patterns of functional brain activity in humans. The occurrence frequency of microstate class D is an important feature in the insomnia population. We therefore hypothesize that the occurrence frequency of microstate class D is a physiological indicator of subjective sleep quality. To test this hypothesis, we recruited college students from China as participants [N = 61, mean age = 20.84 years]. The Chinese version of the Pittsburgh Sleep Quality Index scale was used to measure subjective sleep quality and habitual sleep efficiency, and the state characteristics of the brain at this time were assessed using closed eyes resting-state brain microstate class D. The occurrence frequency of EEG microstate class D was positively associated with subjective sleep quality (r = 0.32, p < 0.05). Further analysis of the moderating effect showed that the occurrence frequency of microstate class D was significantly and positively correlated with subjective sleep quality in the high habitual sleep efficiency group. However, the relationship was not significant in the low sleep efficiency group (βsimple = 0.63, p < 0.001). This study shows that the occurrence frequency of microstate class D is a physiological indicator of assessing subjective sleep quality levels in the high sleep efficiency group. This study provides brain features for assessing subjective sleep quality of people with autism and mental disorders who cannot effectively describe their subjective feelings.
主观睡眠质量是个体的主观睡眠感受，对其进行有效评估是改善睡眠质量的前提。然而，自闭症或精神障碍患者往往在言语表达主观睡眠质量方面存在困难。为了解决上述问题，本研究提供了一种非言语且方便的大脑特征来评估主观睡眠质量。据报道，微状态常用于描述人类大脑功能活动的模式。微状态类 D 的出现频率是失眠人群中的一个重要特征。因此，我们假设微状态类 D 的出现频率是主观睡眠质量的生理指标。为了验证这一假设，我们招募了来自中国的大学生作为参与者[N = 61，平均年龄 = 20.84 岁]。使用匹兹堡睡眠质量指数量表的中文版来衡量主观睡眠质量和习惯性睡眠效率，并使用闭眼静息状态脑微状态类 D 评估此时大脑的状态特征。EEG 微状态类 D 的出现频率与主观睡眠质量呈正相关(r = 0.32，p < 0.05)。进一步的调节效应分析表明，微状态类 D 的出现频率与习惯性高睡眠效率组的主观睡眠质量显著正相关。然而，在低睡眠效率组中，这种关系并不显著(βsimple = 0.63，p < 0.001)。本研究表明，微状态类 D 的出现频率是评估高睡眠效率组主观睡眠质量水平的生理指标。本研究为评估无法有效描述主观感受的自闭症和精神障碍患者的主观睡眠质量提供了大脑特征。
