The proprietary neuropsychological tests (Form C1) of the National Alzheimer’s Coordinating Center (NACC) Uniform Data Set were replaced with nonproprietary versions (Form C2) chosen to closely model their proprietary counterparts. Correlations between analogous test pairs as measured in previous work were good (0.68-0.78), but it is unclear whether the paired tests represent the same set of common factors of cognition or if important factors specific to C1 or C2 only exist. The authors performed multiple factor analysis to analyze correlated C1 and C2 data. They included participants who completed both neuropsychological batteries within 1 year with no change in cognitive status. They found that the C1 and C2 neuropsychological test pairs are strongly related and are represented by the same principal factors. These findings support the use of the C2 test results in conjunction with C1 in longitudinal analyses of NACC data.

NACC 统一数据集中神经心理学测试电池版本的因素一致性。



国家阿尔茨海默氏病协调中心 (NACC) 统一数据集的专有神经心理学测试(表格 C1)被替换为非专有版本(表格 C2),选择与其专有版本密切建模。先前工作中测量的类似测试对之间的相关性良好(0.68-0.78),但尚不清楚配对测试是否代表同一组共同的认知因素,或者是否仅存在 C1 或 C2 特有的重要因素。作者进行了多因素分析来分析相关的 C1 和 C2 数据。他们包括在一年内完成两项神经心理学电池测试且认知状态没有变化的参与者。他们发现 C1 和 C2神经心理学测试对密切相关,并且由相同的主要因素代表。这些发现支持在 NACC 数据的纵向分析中将 C2 测试结果与 C1 结合使用。
