认知筛查对于高龄老人(90 岁以上)非常重要。这个年龄组增长最快,患痴呆症的风险最高。然而,该群体缺乏筛选测试的规范和分数等效性。为老年人常用的认知筛查测试提供规范和分数等效性。对健康老龄化长寿研究中心 157 名 90 岁以上参与者的数据进行了分析。首先,我们得出了 (1) 现场蒙特利尔认知评估的子测试和认知领域的规范,最高分为 30 (MoCA-30) 和 (2) MoCA-22 总分,该总分是通过将不需要视觉输入的子测试求和至最高分 22 分从现场 MoCA-30 获得的。这些规范来自 124 名参加简易精神状态检查的参与者。 (MMSE) ≥ 27. 其次,我们基于所有 157 名参与者,使用对数线性平滑的等百分位方程法推导出 MMSE 与 MoCA-30 和 MoCA-22 以及 MoCA-30 与 MoCA-22 的分数等值。 MoCA-22总分规范为:平均值 = 18.3(标准差 = 2.2)。 MMSE 分数 27 相当于 MoCA-30 分数 22 和 MoCA-22 分数 16。子测试、领域和 MoCA-22 规范将有助于评估无法完成 MoCA-30 或通过电话测试的最年长老人。三种认知测试(MMSE、MoCA-30、MoCA-22)在最年长者中的等效性将有助于随着时间的推移对使用不同测试进行测试的个体的认知跟踪的连续性以及使用不同认知测试的研究的比较。在线版本包含可在 10.1007/s40520-021-01886-z 获取的补充材料。
Cognitive screening is important for the oldest-old (age 90 +). This age group is the fastest growing and has the highest risk of dementia. However, norms and score equivalence for screening tests are lacking for this group. To provide norms and score equivalence for commonly used cognitive screening tests for the oldest-old. Data on 157 participants of the Center for Healthy Aging Longevity Study aged 90 + were analyzed. First, we derived norms for (1) subtests and cognitive domains of the in-person Montreal Cognitive Assessment having a maximum score of 30 (MoCA-30) and (2) the total MoCA-22 score, obtained from the in-person MoCA-30 by summing the subtests that do not require visual input to a maximum score of 22. These norms were derived from 124 participants with a Mini-Mental State Examination (MMSE) ≥ 27. Second, we derived score equivalences for MMSE to MoCA-30 and MoCA-22, and MoCA-30 to MoCA-22 using equipercentile equating method with log-linear smoothing, based on all 157 participants. MoCA-22 total score norms are: mean = 18.3(standard deviation = 2.2). An MMSE score of 27 is equivalent to a MoCA-30 score of 22 and a MoCA-22 score of 16. Subtest, domain and MoCA-22 norms will aid in evaluation of the oldest-old who cannot complete the MoCA-30 or are tested over the phone. The equivalences of the three cognitive tests (MMSE, MoCA-30, MoCA-22) in the oldest-old will facilitate continuity of cognitive tracking of individuals tested with different tests over time and comparison of the studies that use different cognitive tests.
