采用标准参照（利文斯顿）和常模参照（Gilmer-Feldt）技术，在大样本（N = 418）老年内科患者中测量Folstein简易精神状态检查量表（MMSE）的内部一致性信度。研究了MMSE注意力和计算部分的两种给药和评分变体（仅序列7和仅WORLD）。利文斯顿的可靠性系数（rs）计算了广泛的截止分数。作为计算Gilmer-Feldt r的必要条件，因子分析表明MMSE测量三个认知领域。利文斯顿对最广泛使用的MMSE截止分数24的r值，在序列7中为0.803，在WORLD中为0.795。Gilmer-Feldt内部一致性信度系数为0.764（序列7）和0.747（WORLD）。项目分析表明，几乎所有的MMSE项目都是很好的区分器，但有12个项目太容易。在解释MMSE测试分数时，应应用真实分数置信区间。
Criterion-referenced (Livingston) and norm-referenced (Gilmer-Feldt) techniques were used to measure the internal consistency reliability of Folstein's Mini-Mental State Examination (MMSE) on a large sample (N = 418) of elderly medical patients. Two administration and scoring variants of the MMSE Attention and Calculation section (Serial 7s only and WORLD only) were investigated. Livingston reliability coefficients (rs) were calculated for a wide range of cutoff scores. As necessary for the calculation of the Gilmer-Feldt r, a factor analysis showed that the MMSE measures three cognitive domains. Livingston's r for the most widely used MMSE cutoff score of 24 was .803 for Serial 7s and .795 for WORLD. The Gilmer-Feldt internal consistency reliability coefficient was .764 for Serial 7s and .747 for WORLD. Item analysis showed that nearly all of the MMSE items were good discriminators, but 12 were too easy. True score confidence intervals should be applied when interpreting MMSE test scores.
