一种仪器被开发出来，人们可以用它来描述他们入睡时的唤醒状态。设计的工具，睡前唤醒量表（PSAS），是一个16项的自我报告问卷，包括认知和躯体的觉醒表现。为了评估其心理测量特性，对147名大学生、30名成年正常睡眠者和30名失眠症沿着进行了PSAS测试，并测量了焦虑、抑郁和睡眠障碍的自我报告指数。大学生（31）在自己的卧室连续10个晚上监测他们的睡眠行为和睡前觉醒。作为量表有效性的证据，认知和躯体分量表与焦虑，抑郁和睡眠困难的一般指数显着相关。这两个尺度成功地区分失眠症患者从正常睡眠者和相关性显着夜间报告的睡眠开始潜伏期。认知分量表，然而，更强烈地与一般以及夜间睡眠潜伏期的措施比躯体分量表。PSAS可能是一个有用的工具，为未来的研究的睡眠前状态和个人的睡眠障碍的筛查措施。
An instrument was developed which individuals can use to describe their state of arousal as they fall asleep. The instrument devised, the Pre-sleep Arousal Scale (PSAS), is a 16-item self-report questionnaire comprising both cognitive and somatic manifestations of arousal. In order to assess its psychometric properties, the PSAS was administered to 147 college students, 30 adult normal sleepers and 30 insomniacs along with measures of anxiety, depression and self-report indices of sleep disturbance. College students (31) monitored their sleep behavior and pre-sleep arousal over 10 consecutive nights in their own bedrooms. As evidence of the scale''s validity, cognitive and somatic subscales were significantly correlated with anxiety, depression and general indices of sleeping difficulty. Both scales successfully discriminated insomniacs from normal sleepers and correlated significantly with nightly reports of sleep-onset latency. The cognitive subscale, however, was more strongly associated with general as well as nightly sleep-onset latency measures than the somatic subscale. The PSAS may be a useful tool for future studies of the pre-sleep state and a helpful screening measure for individuals with sleep disturbance.
