本研究验证了九点Karolinska嗜睡量表(KSS)和新的有嗜睡累积时间量表(ATS)与实验室任务的执行情况。ATS量表被设计为一种将较长时间段的主观嗜睡进行整合的方法。受试者被问及是否出现了某些嗜睡症状，如果有，持续了多久。六名受试者参加了两次实验。每次他们都在晚上保持清醒(除了在平衡顺序的其中一个晚上发生的小睡)，并在22时、0200时、0400时和600时进行测试。测试包括10分钟的休息时间，28分钟的视觉警戒任务和11分钟的单一反应时间任务。每次测试前进行KSS和视觉模拟评分(VAS)，测试结束后进行ATS评分。表现明显恶化，所有三个评级等级都反映出随着夜间时间的推移，嗜睡程度增加。KSS和VAS得分与绩效任务高度相关(平均个体内相关在0.49~0.71之间)。表现与ATS评分的相关性更高(r=0.73-0.79)。评定量表之间的相关性也很高(r=0.65-0.86)。研究结果表明，困倦程度与作业成绩之间存在很强的相关性，ATS评分量表至少与其他量表一样好，而且评分受任务类型的影响。
The present study validated the nine-point Karolinska Sleepiness Scale (KSS) and the new Accumulated Time with Sleepiness (ATS) scale against performance of laboratory tasks. The ATS scale was designed as a method for integrating subjective sleepiness over longer time periods. The subjects were asked if certain symptoms of sleepiness had occurred and, if so, for how long. Six subjects participated twice. Each time they were kept awake during the night (except for a short nap occurring during one of the nights in a counterbalanced order) and were tested at 2200, 0200, 0400 and 0600 hours. The tests included a 10-minute rest period, a 28-minute visual vigilance task and an 11-minute single reaction time task. KSS and visual analogue scale (VAS) ratings were given before each test, and ATS ratings were given after. Performance deteriorated clearly, and all three rating scales reflected increased sleepiness with time of night. Scores on the KSS and VAS showed high correlations with performance tasks (mean intraindividual correlations were between 0.49 and 0.71). Performance correlated even higher with the ATS ratings (r = 0.73-0.79). Intercorrelations between rating scales were also high (r = 0.65-0.86). It was concluded that there were strong relations between ratings of sleepiness and performance, that the ATS rating scale was at least as good as the other scales and that the ratings were affected by type of task.
