The Montreal Cognitive Assessment (MoCA) is a cognitive screen, available in three alternate versions. Aims of the current study were to examine the effects of age, education and intelligence on MoCA performance and to determine the alternate-form equivalence and test-retest reliability of the MoCA, in a group of healthy participants. In 210 participants, two MoCA versions and an estimator for premorbid intelligence were administered at two time points. Age, education and estimated premorbid intelligence correlated significantly with the total score (MoCA-TS) and the Memory Index Score (MoCA-MIS). Systematic differences between MoCA version 7.1 and alternate versions 7.2 and 7.3 were only found for the items animal naming, abstract reasoning and sentence repetition. Test-retest reliability of the MoCA-TS was good between 7.1 and 7.2 (ICC: 0.64) and excellent between 7.1 and 7.3 (ICC: 0.82). For the MoCA-MIS, coefficients were poor (ICC: 0.32) to fair (ICC: 0.48), respectively. Adequate norms are needed that take the effects of age, education and intelligence on MoCA performance into account. All three MoCA versions are largely equivalent based on MoCA-TS and the test-retest reliabilities show that this score is suitable to monitor cognitive change over time. Comparisons of the domain-specific scores should be interpreted with caution.Key pointsThe MoCA total score is a reliable cognitive measure.All three MoCA versions are largely equivalent.Age, education and intelligence are predictors of MoCA performance in healthy participants.Future studies should focus on collecting normative data for age, education and intelligence for use in clinical practice.
蒙特利尔认知评估（MoCA）是一种认知筛查工具，有三种备用版本。本研究旨在考察年龄、教育和智力对 MoCA 表现的影响，并确定 MoCA 在一组健康参与者中的等价形式和重测信度。在 210 名参与者中，两次使用 MoCA 的两种版本和一种用于预测前摄智力的测试，在两个时间点进行测试。年龄、教育和估计的前摄智力与总得分（MoCA-TS）和记忆指数得分（MoCA-MIS）显著相关。MoCA 版本 7.1 与备用版本 7.2 和 7.3 之间仅在动物命名、抽象推理和句子重复这三个项目上存在系统差异。MoCA-TS 在 7.1 和 7.2 之间的重测信度较好（ICC：0.64），在 7.1 和 7.3 之间的重测信度极好（ICC：0.82）。对于 MoCA-MIS，系数分别为较差（ICC：0.32）到中等（ICC：0.48）。需要制定充分的规范，考虑年龄、教育和智力对 MoCA 表现的影响。基于 MoCA-TS，所有三个 MoCA 版本基本等效，且重测信度表明该分数适用于监测随时间推移的认知变化。对于特定领域的分数的比较应谨慎解释。
MoCA 总分是一种可靠的认知测量工具。
所有三个 MoCA 版本基本等效。
年龄、教育和智力是健康参与者 MoCA 表现的预测因素。
未来的研究应重点收集年龄、教育和智力的正常数据，用于临床实践。
