To establish Montreal Cognitive Assessment (MoCA) scores that correspond to well-established cut-points on the Mini-Mental State Examination (MMSE).
Cross-sectional observational study.
General medical service of a large teaching hospital.
Individuals aged 75 and older (N = 199; mean age 84, 63% female).
The MoCA (range 0-30) and the MMSE (range 0-30) were administered within 2 hours of each other. The Abbreviated MoCA (A-MoCA; range 0-22) was calculated from the full MoCA. Scores from the three tests were analyzed using equipercentile equating, a statistical method for determining comparable scores on different tests of a similar construct by estimating percentile equivalents.
MoCA scores were lower (mean 19.3 ± 5.8) than MMSE scored (mean 24.1 ± 6.6). Traditional MMSE cut-points of 27 for mild cognitive impairment and 23 for dementia corresponded to MoCA scores of 23 and 17, respectively.
Scores on the full and abbreviated versions of the MoCA can be linked directly to the MMSE. The MoCA may be more sensitive to changes in cognitive performance at higher levels of functioning.
确定与简易精神状态检查表（MMSE）既定切点相对应的蒙特利尔认知评估（MoCA）分数。
横断面观察性研究。
一家大型教学医院的普通医疗服务部门。
75岁及以上的个体（N = 199；平均年龄84岁，63%为女性）。
MoCA（范围0 - 30）和MMSE（范围0 - 30）在彼此2小时内进行测试。简易MoCA（A - MoCA；范围0 - 22）由完整的MoCA计算得出。使用等百分位等值法分析这三项测试的分数，这是一种通过估计百分位等效值来确定类似结构不同测试中可比分数的统计方法。
MoCA分数（均值19.3±5.8）低于MMSE分数（均值24.1±6.6）。传统的MMSE轻度认知障碍切点27和痴呆切点23分别对应MoCA分数23和17。
MoCA完整版本和简易版本的分数可直接与MMSE相关联。MoCA可能对较高功能水平下认知表现的变化更敏感。
