随着研究越来越关注阿尔茨海默病（AD）的临床前阶段，必须重新调整仪器以识别AD的早期认知标志物。阿尔茨海默病评估量表的补充延迟回忆子测验-认知（ADAS-cog; Mohs，罗森，& Davis，1983;罗森，Mohs，& Davis，1984）通常被实施，但是并不精确地知道该子测试在认知功能障碍谱的沿着何处产生超出从标准ADAS-cog获得的增量信息，或者它是否可以改善功能结果的预测。项目反应理论方法可以用心理测量学上严格的方式来分析这一点。788例AD或遗忘症或功能障碍患者完成了一系列包括ADAS-cog和2项日常生活活动测量的测试。延迟回忆子测试略微提高了ADAS-cog在轻度认知功能障碍范围内的测量精度，并增加了主观记忆障碍个体对工具性日常生活活动的预测。（PsycInfo数据库记录（c）2020阿帕，保留所有权利）
As research increasingly focuses on preclinical stages of Alzheimer’s disease (AD), instruments must be retooled to identify early cognitive markers of AD. A supplemental delayed recall subtest for the Alzheimer’s Disease Assessment Scale-cognitive (ADAS-cog; Mohs, Rosen, & Davis, 1983; Rosen, Mohs, & Davis, 1984) is commonly implemented, but it is not known precisely where along the spectrum of cognitive dysfunction this subtest yields incremental information beyond what is gained from the standard ADAS-cog, or whether it can improve prediction of functional outcomes. An item response theory approach can analyze this in a psychometrically rigorous way. Seven hundred eighty-eight patients with AD or amnestic complaints or impairment completed a battery including the ADAS-cog and 2 activities of daily living measures. The delayed recall subtest slightly improved the ADAS-cog’s measurement precision in the mild range of cognitive dysfunction and increased prediction of instrumental activities of daily living for individuals with subjective memory impairment.(PsycInfo Database Record (c) 2020 APA, all rights reserved)
