The Cognitive Abilities Screening Instrument (CASI) is increasingly used to assess general cognitive function in people with dementia. The Mini-Mental State Examination (MMSE) score can be converted from the CASI (i.e., the estimated MMSE). Recognizing that measurement equivalence is critical to meaningfully representing one with the other, we aimed to determine whether the estimated MMSE score obtained from the CASI was equivalent to the original MMSE in people with dementia.
We obtained 110 data points for the MMSE and CASI scores in people with dementia. The intraclass correlation coefficient (ICC), Pearson's , percent of standard error of measurement (SEM%), paired -test, and effect size (Cohen's ) were used to investigate the equivalence.
To examine the equivalence between the original and estimated MMSE score, the ICC and Pearson's of the total score and six domains were 0.62-0.95 and 0.62-0.96, respectively. The SEM% of the total score and six domains were 0.6-8.9%. The paired -test results showed a significant difference ( < 0.05) between the total score and the three domains. The Cohen's of the total score and six domains were 0.06-0.27.
The estimated MMSE score was found to have moderate to excellent equivalence to the original MMSE score. The three domains (i.e., registration, attention and calculation, and visual-constructional ability) with moderate equivalence should be used cautiously to interchange with the original MMSE in people with dementia.
认知能力筛查工具（CASI）越来越多地用于评估痴呆患者的一般认知功能。可以从 CASI 转换出简易精神状态检查（MMSE）的分数（即估计的 MMSE）。鉴于测量等效性对于有意义地代表另一个至关重要，我们旨在确定 CASI 获得的估计 MMSE 分数在痴呆患者中是否与原始 MMSE 等效。
我们获得了 110 名痴呆患者的 MMSE 和 CASI 分数数据点。使用组内相关系数（ICC）、Pearson's 、测量标准误差百分比（SEM%）、配对检验和效应量（Cohen's ）来研究等效性。
为了检验原始和估计的 MMSE 分数之间的等效性，总分和六个领域的 ICC 和 Pearson's 分别为 0.62-0.95 和 0.62-0.96。总分和六个领域的 SEM%分别为 0.6-8.9%。配对检验结果显示总分和三个领域之间存在显著差异（<0.05）。总分和六个领域的 Cohen's 分别为 0.06-0.27。
估计的 MMSE 分数与原始 MMSE 分数具有中等至高的等效性。具有中等等效性的三个领域（即登记、注意力和计算以及视觉构建能力）应谨慎用于在痴呆患者中与原始 MMSE 互换。
