Sleep problems have a high prevalence and negative daytime consequences in adolescents. Current sleep measures for this age group have limitations. The Patient-Reported Outcomes Measurement Information System (PROMIS ) developed sleep item banks for adults. In a previous validation study, these item banks were adapted to a shortened version for adolescents. The current study aimed to further explore the psychometric properties of the 11-item Sleep-Related Impairment and 23-item Sleep Disturbance item banks in Dutch adolescents. We investigated structural validity by testing item response theory assumptions and model fit; measurement invariance by performing differential item functioning analyses; performance as a computerized adaptive test; reliability by marginal reliability estimates and test-retest reliability (intraclass correlation coefficients and limits of agreement); and construct validity by hypothesis testing. Additionally, we provide mean values for the item banks. The study sample consisted of 1,046 adolescents (mean age 14.3 ± 1.6), including 1,013 high-school students and 33 sleep-clinic patients. The Sleep Disturbance-23 showed lack of unidimensionality, but had sufficient test-retest reliability, and could distinguish between adolescents with and without sleep or health issues. The Sleep-Related Impairment-11 showed sufficient unidimensionality and model fit and was thus tested as a computerized adaptive test, demonstrating an equal amount of reliable measures to the full item bank. Furthermore, the Sleep-Related Impairment-11 could distinguish between adolescents with and without sleep or health issues and test-retest reliability was moderate. The use of both item banks in the full form and the use of the Sleep-related Impairment-11 as a computer adaptive test is recommended.
睡眠问题在青少年中普遍存在，并会对白天产生负面影响。目前针对该年龄段的睡眠测量方法存在局限性。患者报告的结果测量信息系统（PROMIS）为成年人开发了睡眠项目库。在之前的验证研究中，这些项目库被改编为适用于青少年的缩短版。本研究旨在进一步探讨荷兰青少年的 11 项睡眠障碍和 23 项睡眠障碍项目库的心理测量特性。我们通过测试项目反应理论假设和模型拟合来研究结构有效性；通过进行差异项目功能分析来研究测量不变性；通过计算机化自适应测试来研究性能；通过边缘可靠性估计和重测信度（组内相关系数和一致性界限）来研究可靠性；通过假设检验来研究结构有效性。此外，我们还提供了项目库的平均值。研究样本包括 1046 名青少年（平均年龄 14.3±1.6 岁），包括 1013 名高中生和 33 名睡眠诊所患者。睡眠障碍-23 显示缺乏单维性，但具有足够的重测信度，并且可以区分有睡眠或健康问题的青少年和没有睡眠或健康问题的青少年。睡眠障碍-11 显示出足够的单维性和模型拟合，因此被测试为计算机化自适应测试，与完整的项目库相比，它可以提供同等数量的可靠测量结果。此外，睡眠障碍-11 可以区分有睡眠或健康问题的青少年和没有睡眠或健康问题的青少年，重测信度为中等。建议同时使用两个项目库的完整形式和将睡眠障碍-11 作为计算机自适应测试使用。
