埃普沃思嗜睡量表（ESS）是一个自我管理的八项问卷，已被提议作为一个简单的方法来衡量白天嗜睡的成年人。对87名健康医学生进行测试，5个月后进行复测，其配对ESS评分无显著变化，且高度相关（r = 0.82）。相比之下，54例阻塞性睡眠呼吸暂停综合征患者的ESS评分最初很高，在经鼻持续气道正压通气治疗3-9个月后恢复到正常水平。该问卷具有较高的内部一致性，Cronbach的α（0.88）。项目得分的因素分析表明，ESS只有一个因素的104名医学生和150例各种睡眠障碍患者。ESS是一种简单可靠的测量成年人持续白天嗜睡的方法。关键
The Epworth Sleepiness Scale (ESS) is a self-administered eight-item questionnaire that has been proposed as a simple method for measuring daytime sleepiness in adults. This investigation was concerned with the reliability and internal consistency of the ESS. When 87 healthy medical students were tested and retested 5 months later, their paired ESS scores did not change significantly and were highly correlated (r = 0.82). By contrast, ESS scores that were initially high in 54 patients suffering from obstructive sleep apnea syndrome returned to more normal levels, as expected, after 3-9 months' treatment with nasal continuous positive airway pressure. The questionnaire had a high level of internal consistency as measured by Cronbach's alpha (0.88). Factor analysis of item scores showed that the ESS had only one factor for 104 medical students and for 150 patients with various sleep disorders. The ESS is a simple and reliable method for measuring persistent daytime sleepiness in adults. Key
