The primary objectives of this study were to construct a self-assessment questionnaire for sleep disorders based on the International Classification of Sleep Disorders-2, and to evaluate the questionnaire's psychometric properties with respect to its total score and the individual scores for each of the six sleep disorders. In total, 1269 patients, clinically diagnosed with a sleep disorder, and 412 subjects without sleep complaints were enrolled into this study. Principal components analysis confirmed that the Holland Sleep Disorders Questionnaire differentially represented the six symptom clusters associated with International Classification of Sleep Disorders-2 classifications. The Holland Sleep Disorders Questionnaire's total score distinguished patients with a clinically diagnosed sleep disorder from individuals without sleep complaints, with area under the receiver operating curve P(A) of 0.95. The internal reliability coefficient alpha was 0.90 and, applying the Youden criterion as cutoff score, the overall accuracy was 88% (κ: 0.75). Subsequently, the six diagnostic groups of sleep-disordered patients could be differentiated reliably, with P(A) values ranging between 0.69 and 0.95, alpha coefficients ranging between 0.73 and 0.81 and an overall percentage of 85% correctly classified patients (κ = 0.80), indicating a substantial to excellent agreement between the primary diagnoses and the Holland Sleep Disorders Questionnaire classifications.
本研究的主要目的是基于《国际睡眠障碍分类-2》构建睡眠障碍自评问卷，并评估问卷总分及 6 种睡眠障碍各单项得分的心理测量学特性。共纳入 1269 例临床诊断为睡眠障碍的患者和 412 例无睡眠抱怨的受试者。主成分分析证实，荷兰睡眠障碍问卷能较好地区分与《国际睡眠障碍分类-2》分类相关的 6 个症状簇。荷兰睡眠障碍问卷总分能将临床诊断为睡眠障碍的患者与无睡眠抱怨的个体区分开来，受试者工作特征曲线下面积 P(A)为 0.95。内部信度系数α为 0.90，采用约登指数作为截断值，总准确率为 88%（κ：0.75）。随后，6 种睡眠障碍患者的诊断组可以可靠地区分，受试者工作特征曲线下面积 P(A)值在 0.69 到 0.95 之间，α系数在 0.73 到 0.81 之间，85%的患者分类正确（κ=0.80），表明主要诊断与荷兰睡眠障碍问卷分类之间存在显著至极好的一致性。
