构建了由10厘米线模拟评级量表问题组成的自我完成睡眠评估问卷（SEQ），以调查受试者对睡眠和清晨行为方面的反应。这些问题被分为4个时间顺序领域：入睡难易度（GTS）、感知睡眠质量（QOS）、从睡眠中醒来的难易度（AFS）和清醒后清晨行为的完整性（BFW）。在对催眠药物的比较有效性进行的几项研究中，完成了501个SEQ。经典的因子分析产生了4个因子，对应于上述睡眠和清晨行为的4个方面。GTS和QOS因子呈正相关（+ 0·57），AFS和BFW因子也呈正相关（+ 0·48）。2个睡眠状态因子（GTS和QOS）与2个清醒状态因子（AFS和BFW）正交。
A self-completion sleep evaluation questionnaire (SEQ), consisting of 10 cm line analogue rating scale questions, was constructed to investigate subjects' responses to aspects of sleep and early morning behaviour. The questions were grouped into 4 chronological areas: the ease of getting to sleep (GTS), the perceived quality of sleep (QOS), the ease of awakening from sleep (AFS), and the integrity of early morning behaviour following wakefulness (BFW). Five hundred and one SEQs were completed during several investigations into the comparative effectiveness of hypnotic drugs. The classical factor analysis produced 4 factors which corresponded to the 4 aspects of sleep and early morning behaviour listed above. The GTS and QOS factors were positively correlated (+ 0·57), as were the AFS and BFW factors (+ 0·48). The 2 sleeping state factors (GTS and QOS) were orthogonal to the 2 waking state factors (AFS and BFW).
