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).
构建了一份自我完成式睡眠评估问卷（SEQ），由10厘米的线性模拟评分量表问题组成，以调查受试者对睡眠及清晨行为各方面的反应。这些问题按时间顺序分为4个方面：入睡难易程度（GTS）、睡眠感知质量（QOS）、从睡眠中醒来的难易程度（AFS）以及醒来后清晨行为的完整性（BFW）。在几项关于催眠药物比较疗效的研究中，共完成了501份SEQ。经典因子分析产生了4个因子，分别对应上述睡眠和清晨行为的4个方面。入睡难易程度（GTS）和睡眠感知质量（QOS）因子呈正相关（+0.57），从睡眠中醒来的难易程度（AFS）和醒来后清晨行为的完整性（BFW）因子也是如此（+0.48）。两个睡眠状态因子（GTS和QOS）与两个清醒状态因子（AFS和BFW）相互正交。
