本文详细介绍了睡眠障碍问卷（SDQ）的发展过程，它是由斯坦福大学的睡眠问卷和觉醒评估（SQAW）发展而来的。描述了从SQAW中提取最佳问题项及其随后在SDQ中的改写，以确保更高的完成率。两个项目的重测信度研究报告71控制和130睡眠障碍患者，证实了足够的可靠性。为了建立多变量评分量表，SDQ在一项多中心研究中对519人进行了研究，其中435人是睡眠障碍患者，进行了全面的多导睡眠图检查。采用典型判别函数分析，这导致了四个临床诊断量表：SA的睡眠呼吸暂停，NAR的发作性睡病，PSY的精神性睡眠障碍和PLM的周期性肢体运动障碍。根据男性和女性的反应调整每个值，并使用观察到的原始评分分布转换为百分位数。使用受试者操作特征分析，确定每个量表的截止点，以最大限度地提高其灵敏度和特异性。还计算了阳性和阴性预测值。SA和NAR量表被证明是最具鉴别力的。
The development of the Sleep Disorders Questionnaire (SDQ) from the Sleep Questionnaire and Assessment of Wakefulness (SQAW) of Stanford University is described in detail. The extraction of the best question items from the SQAW and their subsequent rewording in the SDQ to insure greater completion rates are described. Two item test-retest reliability studies are reported on 71 controls and on 130 sleep-disorder patients, which confirmed adequate reliability. To create multivariate scoring scales, SDQ was then given in a multicenter study to 519 persons, 435 of whom were sleep-disorder patients with full polysomnography. Canonical Discriminant Function Analysis was employed, which resulted in four clinical-diagnostic scales: SA for sleep apnea, NAR for narcolepsy, PSY for psychiatric sleep disorder and PLM for periodic limb movement disorder. Each was adjusted for male and female responses and transformed to a percentile using the observed distribution of raw scores. Using Receiver Operating Characteristics analysis, cutoff points were determined for each scale to maximize its sensitivity and specificity. Positive and negative predictive values were also calculated. The SA and NAR scales proved to be the most discriminating.
