这项调查研究了一种测试情况下的睡眠倾向 (SP)，例如多次睡眠潜伏期测试 (MSLT)，与日常生活中的嗜睡程度之间的关系，并通过 Epworth 嗜睡量表 (ESS) 进行评估。这是一份自填问卷，其中的项目评分提供了一种在八种不同的现实生活情况下测量 SP 的新方法。 ESS 项目得分分别在四组受试者中进行分析：150 名患有各种睡眠障碍的成年患者、87 名相隔 5 个月两次回答 ESS 的医学生、44 名也有 MSLT 的患者以及 50 名其配偶也回答了有关伴侣困倦的 ESS 的患者。 ESS 项目评分被证明是可靠的（平均 rho = 0.56，p < 0.001）。 MSLT 测量的 SP 与多元回归中八个项目得分中的三个相关（r = 0.64，p < 0.001）。非参数方差分析、Spearman 相关、Wilcoxon t 检验、项目和因子分析的结果表明，除了几小时或几天内的短期变化之外，SP 的个体测量还涉及三个变异组成部分：受试者的一般特征（他的平均 SP）、测量 SP 的情况的一般特征（其催眠性质）以及针对受试者和情况特定的第三个组成部分。一种测试情况下的 SP（包括 MSLT）可能不是受试者日常生活中平均 SP 的可靠指标。也许我们应该重新审视当前白天嗜睡的概念及其测量。
This investigation examines how the sleep propensity (SP) in one test situation, such as the Multiple Sleep Latency Test (MSLT), is related to sleepiness in daily life, as assessed by the Epworth Sleepiness Scale (ESS). This is a self-administered questionnaire, the item scores from which provide a new method for measuring SPs in eight different real-life situations. The ESS item scores were analyzed separately in four groups of subjects: 150 adult patients with a variety of sleep disorders, 87 medical students who answered the ESS on two occasions 5 months apart, 44 patients who also had MSLTs and 50 patients whose spouses also answered the ESS about their partner's sleepiness. The ESS item scores were shown to be reliable (mean rho = 0.56, p < 0.001). The SP measured by the MSLT was related to three of the eight item scores in a multiple regression (r = 0.64, p < 0.001). The results of nonparametric ANOVA, Spearman correlations, Wilcoxon's t tests, item and factor analysis suggest that individual measurements of SP involve three components of variation in addition to short-term changes over periods of hours or days: a general characteristic of the subject (his average SP), a general characteristic of the situation in which SP is measured (its soporific nature) and a third component that is specific for both subject and situation. The SP in one test situation, including the MSLT, may not be a reliable indicator of a subject's average SP in daily life. Perhaps we should reexamine the current concept of daytime sleepiness and its measurement.
