Despite the Rowland Universal Dementia Assessment Scale (RUDAS) having significant advantages as a cognitive screening tool, particularly for minority populations, the Mini-Mental State Examination (MMSE) test is the most widely used test for cognitive screening in Alzheimer's disease (AD). This study aimed to develop a conversion table to predict MMSE scores from observed RUDAS scores, allowing an easy-to-use method to compare both screening tests.
The equipercentile equating method was used to develop the conversion table using a training sample consisting of cognitively intact participants and individuals with early-stage AD. The resulting conversion table was validated in two samples, comprising participants from majority and minority populations assessed in Spanish.
The conversion table demonstrated excellent reliability with intraclass correlation coefficients of.92 in both validation samples.
This study provides a conversion table between RUDAS and MMSE scores, improving the comparability of these cognitive screening tools for use in clinical and research purposes.
尽管罗兰普遍痴呆评估量表（RUDAS）作为认知筛查工具具有显著优势，特别是对少数族裔人群而言，但简易精神状态检查（MMSE）测试仍是阿尔茨海默病（AD）认知筛查中使用最广泛的测试。本研究旨在制定一个转换表，根据观察到的 RUDAS 评分预测 MMSE 评分，以便更轻松地比较两种筛查测试。
使用等百分位等距法，使用包含认知正常参与者和早期 AD 患者的训练样本制定转换表。在两个样本中验证了转换表，其中包括在西班牙语评估的多数族裔和少数族裔人群的参与者。
转换表在两个验证样本中的内类相关系数均为.92，显示出极好的可靠性。
本研究提供了 RUDAS 和 MMSE 评分之间的转换表，提高了这些认知筛查工具在临床和研究中的可比性。
