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.
采用标准参照（利文斯顿）和常模参照（吉尔默 - 费尔特）技术，对大量老年内科患者样本（N = 418）进行福尔斯坦简易精神状态检查表（MMSE）内部一致性信度测量。研究了MMSE注意力和计算部分的两种施测及计分变体（仅连续减7和仅WORLD）。针对广泛的临界分数计算了利文斯顿信度系数（rs）。为计算吉尔默 - 费尔特r，进行了因子分析，结果表明MMSE测量三个认知领域。对于最常用的MMSE临界分数24，连续减7的利文斯顿r为0.803，WORLD为0.795。连续减7的吉尔默 - 费尔特内部一致性信度系数为0.764，WORLD为0.747。项目分析表明，几乎所有MMSE项目都是良好的区分度指标，但有12个过于简单。解释MMSE测试分数时应应用真分数置信区间。
