While sleep disturbances are prevalent in older people and are linked with poor health and cognitive outcomes, screening for the range of sleep disturbances is inefficient and therefore not ideal nor routine in memory and cognition clinic settings. We aimed to develop and validate a new brief self-report questionnaire for easy use within memory and cognition clinics. The design for this study was cross-sectional. Older adults (aged ≥50 in Sydney, Australia) were recruited from a memory and cognition research clinic. Participants (N = 497, mean age 67.7 years, range 50-86, 65.0% female) completed a comprehensive medical, neuropsychological, and mental health assessment, alongside self-report instruments, including existing sleep questionnaires and a new 10-item sleep questionnaire, the CogSleep Screener. We examined the factor structure, convergent validity, internal consistency, and discriminant validity of this novel questionnaire. Using exploratory factor analysis, a 3-factor solution was generated highlighting the factors of Insomnia, Rapid Eye Movement (REM) Symptoms and Daytime Sleepiness. Each factor was significantly correlated with currently used sleep questionnaires for each subdomain (all Spearman rho >0.3, all p < 0.001), suggesting good convergent validity. Internal consistency was also good (Revelle's ω = .74). Receiver operating characteristic curves showed good discriminative ability between participants with and without sleep disturbances (all area under curve >0.7, all p < 0.01). The CogSleep Screener has good psychometric properties in older to elderly adults attending a memory and cognition clinic. The instrument has the potential to be used in memory clinics and other clinical settings to provide quick and accurate screening of sleep disturbances.

虽然睡眠障碍在老年人中很普遍，并且与健康状况不佳和认知结果有关，但对一系列睡眠障碍进行筛查效率低下，因此在记忆与认知诊所环境中并非理想做法，也不是常规操作。我们旨在开发并验证一种新的简短自我报告问卷，以便在记忆与认知诊所中轻松使用。本研究的设计为横断面研究。从一家记忆与认知研究诊所招募了年龄较大的成年人（澳大利亚悉尼年龄≥50岁）。参与者（N = 497，平均年龄67.7岁，范围50 - 86岁，65.0%为女性）完成了全面的医学、神经心理学和心理健康评估，以及自我报告工具，包括现有的睡眠问卷和一份新的10项睡眠问卷——认知睡眠筛查量表（CogSleep Screener）。我们检查了这份新问卷的因子结构、收敛效度、内部一致性和区分效度。通过探索性因子分析，生成了一个三因子解决方案，突出了失眠、快速眼动（REM）症状和日间嗜睡等因子。每个因子与当前用于每个子领域的睡眠问卷均显著相关（所有斯皮尔曼相关系数>0.3，所有p < 0.001），表明具有良好的收敛效度。内部一致性也良好（雷维尔ω系数 = 0.74）。受试者工作特征曲线显示，在有睡眠障碍和无睡眠障碍的参与者之间具有良好的区分能力（所有曲线下面积>0.7，所有p < 0.01）。认知睡眠筛查量表在就诊于记忆与认知诊所的老年人至高龄成年人中具有良好的心理测量学特性。该工具有可能用于记忆诊所和其他临床环境，以快速准确地筛查睡眠障碍。[2025年4月首次发表后添加的更正：参与者数量已更新，相关统计数据也已更新]
