The purpose of this study was to compare the validity and reliability of the two Korean versions of the MoCA for individuals aged ≥65 years.
A total of 185 participants aged ≥65 years were included in this cross-sectional study. This study investigated the reliability of the two Korean versions of the MoCA (the MoCA-K and MoCA-K2) by having each participant complete both assessments twice and comparing them to their Korean version of the Mini-Mental State Exam (MMSE-K) scores. The participants either completed the tests in order A (MoCA-K2 before MoCA-K) then B (MoCA-K before MoCA-K2) or vice versa. The tests were then completed in the opposite order. This study conducted all experiments at 3-day intervals.
Of the 185 total participants analyzed, 95 indicated cognitive impairment, while 90 had normal in MoCA-K scores; 50 demonstrated cognitive impairment, while 135 had normal in MMSE-K scores; and 101 and 84 participants showed cognitive impairment and normal in MoCA-K2 scores, respectively. Cronbach's values were 0.929 for the MoCA-K, 0.774 for the MMSE-K, and 0.919 for the MoCA-K2. The mean scores were 22.37, 25.29, and 21.96 points for the MoCA-K, MMSE-K, and MoCA-K2, respectively. The sensitivity and the specificity of the MoCA-K were 77.0% and 78.0%, respectively, while those of the MoCA-K2 were 68.9% and 80.0%, respectively.
These results suggest that both the MoCA-K and MoCA-K2 are suitable and reliable evaluation tools for MCI screening; however, the MoCA-K had better overall sensitivity and specificity.
本研究旨在比较两种适用于≥65 岁人群的 MoCA 韩文版的有效性和可靠性。
本横断面研究共纳入 185 名≥65 岁的参与者。本研究通过让每位参与者两次完成两种 MoCA 韩文版（MoCA-K 和 MoCA-K2）的评估，并将其与他们的韩文版 Mini-Mental State Exam（MMSE-K）评分进行比较，来研究两种 MoCA 韩文版（MoCA-K 和 MoCA-K2）的可靠性。参与者要么按顺序 A（MoCA-K2 在前 MoCA-K 在后）和 B（MoCA-K 在前 MoCA-K2 在后）完成测试，要么反之。然后按相反的顺序完成测试。本研究在 3 天的间隔内进行了所有实验。
在分析的 185 名总参与者中，95 名表现出认知障碍，而 90 名 MoCA-K 评分正常；50 名表现出认知障碍，而 135 名 MMSE-K 评分正常；101 名和 84 名参与者的 MoCA-K2 评分分别显示出认知障碍和正常。MoCA-K 的 Cronbach's 值为 0.929，MMSE-K 为 0.774，MoCA-K2 为 0.919。MoCA-K、MMSE-K 和 MoCA-K2 的平均得分分别为 22.37、25.29 和 21.96 分。MoCA-K 的灵敏度和特异性分别为 77.0%和 78.0%，MoCA-K2 的灵敏度和特异性分别为 68.9%和 80.0%。
这些结果表明，MoCA-K 和 MoCA-K2 都是适合和可靠的 MCI 筛查评估工具；然而，MoCA-K 的整体灵敏度和特异性更好。
