Abstract. The Montreal Cognitive Assessment (MoCA) is a test assessing global cognition in older adults which is often used by researchers and clinicians worldwide, although some of its psychometric properties have yet to be established. We focus on three fundamental aspects: the factorial structure of the MoCA, its general factor saturation, and the measurement invariance of the test. We administered the MoCA to a large sample of Japanese older adults clustered in three cohorts (69–71-year-olds, 79–81-year-olds, and 89–91-year-olds; N = 2,408). Our results show that the test has an overall stable hierarchical factorial structure with a general factor at its apex and satisfactory general-factor saturation. We also found measurement invariance across participants of different ages, educational levels, economic status, and sex. This comprehensive investigation thus supports the idea that the MoCA is a valid tool to assess global cognition in older adults of different socioeconomic status and age ranges.

蒙特利尔认知评估 (MoCA) 的心理测量学特性

摘要。蒙特利尔认知评估 (MoCA) 是一项评估老年人全球认知能力的测试，世界各地的研究人员和临床医生经常使用它，尽管它的一些心理测量特性尚未确定。我们关注三个基本方面：MoCA 的因子结构、其一般因子饱和度和测试的测量不变性。我们将 MoCA 应用于集中在三个队列中的大量日本老年人样本（69-71 岁、79-81 岁和 89-91 岁；N = 2,408）。我们的结果表明，该检验具有整体稳定的层次因子结构，一般因子在其顶点，一般因子饱和度令人满意。我们还发现不同年龄、教育水平、经济状况和性别的参与者之间的测量不变性。
