Objective:

Compare a telephone version and full version of the Montreal Cognitive Assessment (MoCA).

Methods:

Cross-sectional analysis of a prospective study. A 20-point telephone version of MoCA (Tele-MoCA) was compared to the Full-MoCA and Mini Mental State Examination.

Results:

Total of 140 participants enrolled. Mean scores for language were significantly lower with Tele-MoCA than with Full-MoCA (P = .003). Mean Tele-MoCA scores were significantly higher for participants with over 12 years of education (P < .001). Cutoff score of 17 for the Tele-MoCA yielded good specificity (82.2%) and negative predictive value (84.4%), while sensitivity was low (18.2%).

Conclusions:

Remote screening of cognition with a 20-point Tele-MoCA is as specific for defining normal cognition as the Full-MoCA. This study shows that telephone evaluation is adequate for virtual cognitive screening. Our sample did not allow accurate assessment of sensitivity for Tele-MoCA in detecting MCI or dementia. Further studies with representative populations are needed to establish sensitivity.

蒙特利尔认知评估电话版的评估：从横断面研究中确定规范数据的截止值

客观的：

比较蒙特利尔认知评估 (MoCA) 的电话版和完整版。

方法：

一项前瞻性研究的横断面分析。MoCA (Tele-MoCA) 的 20 点电话版本与 Full-MoCA 和迷你精神状态检查进行了比较。

结果：

共有140名参与者报名。Tele-MoCA 的语言平均分显着低于 Full-MoCA (P = .003)。受过 12 年以上教育的参与者的平均 Tele-MoCA 分数显着更高（P < .001）。Tele-MoCA 的截止分数为 17，具有良好的特异性 (82.2%) 和阴性预测值 (84.4%)，而敏感性较低 (18.2%)。

结论：

使用 20 点 Tele-MoCA 对认知进行远程筛查对于定义正常认知与 Full-MoCA 一样具体。这项研究表明，电话评估足以进行虚拟认知筛查。我们的样本无法准确评估 Tele-MoCA 在检测 MCI 或痴呆方面的敏感性。需要对具有代表性的人群进行进一步的研究以确定敏感性。
