The objectives were 1) to investigate differences among patients with subjective insomnia (sleep state misperception), patients with objective findings of insomnia, and normal volunteers and 2) to assess the consistency of the sleep findings during a 2-month period.
Twenty-one subjects were studied. Subjects with sleep state misperception (N = 7) had insomnia complaints for more than 1 year, no objective sleep disturbance, and sleep efficiency of 90% or greater (on the diagnostic screening sleep recording), while subjectively estimating that sleep time was less than 6.5 hours. Subjects with objective insomnia (N = 7) met the same subjective criteria, but objectively sleep efficiency was 85% or less. Normal subjects (N = 7) had no insomnia complaints and objective sleep efficiency of 90% or greater. All subjects were recorded on 2 consecutive nights three times with a 3-week period between each pair of nights (6 standard all-night polysomnographic sessions of 8 hours). A subjective sleep questionnaire was administered after each sleep recording night.
Sleep stage variables (percentages) were similar between the two insomnia groups, and both were different from the normal subjects. Sleep continuity variables were disturbed in the objective insomnia group, but they were similar in the sleep state misperception and normal groups. Both insomnia groups rated their sleep as inadequate on the questionnaires and differed from the normal subjects. The distinct sleep patterns of each of the three groups did not vary over the 6 nights of assessment.
Sleep state misperception may be a prodromic or transitional state of sleep dysfunction between normal sleep and the sleep pattern of objective insomnia.
目标为1）研究主观失眠（睡眠状态错误认知）患者、有失眠客观表现的患者与正常志愿者之间的差异，以及2）评估2个月期间睡眠结果的一致性。
对21名受试者进行研究。有睡眠状态错误认知的受试者（N = 7）有超过1年的失眠主诉，无客观睡眠障碍，睡眠效率为90%或更高（在诊断性筛查睡眠记录中），而主观估计睡眠时间少于6.5小时。有客观失眠的受试者（N = 7）符合相同的主观标准，但客观睡眠效率为85%或更低。正常受试者（N = 7）无失眠主诉，客观睡眠效率为90%或更高。所有受试者连续两晚进行三次记录，每对记录之间间隔3周（共6次标准的8小时整夜多导睡眠图监测）。每次睡眠记录当晚后进行主观睡眠问卷调查。
两个失眠组之间的睡眠阶段变量（百分比）相似，且均与正常受试者不同。客观失眠组的睡眠连续性变量受到干扰，但在睡眠状态错误认知组和正常组中相似。两个失眠组在问卷中都将自己的睡眠评为不足，且与正常受试者不同。在6晚的评估期间，三组各自独特的睡眠模式没有变化。
睡眠状态错误认知可能是正常睡眠与客观失眠睡眠模式之间睡眠功能障碍的前驱或过渡状态。
