There have been attempts to modify the Montreal Cognitive Assessment (MoCA), a brief cognitive screening tool, for use across several Asian countries, but evidence to support the utility of these translations has been limited, particularly for the Vietnamese translation of the MoCA (MoCA-V). This two-part study aimed to evaluate the MoCA-V in a Vietnamese sample. In the first stage, we examined the relationships between the MoCA-V subscales and common neuropsychological tests among healthy Vietnamese adults ( = 129) and individuals with moderate-to-severe traumatic brain injury ( = 80). In the second stage, we explored the relationship of TBI status (TBI vs non-TBI) and demographic variables to MoCA-V performance and investigated the optimal cut-off score of the MoCA-V using the two samples combined. The MoCA-V Attention, Language, and Executive Function subscales were correlated with the Digit Span Test, Verbal Fluency Test, and Trail Making Test, respectively, across healthy participants and participants with TBI. Global performance on the MoCA-V was predicted by TBI status, education, and age. Our ROC analysis revealed that a cut-off score of 22 offered the best sensitivity (76.3%) and specificity (71.3%) trade-off for identifying cognitive impairment as measured by the MoCA-V. In addition to identifying a cut-off score for cognitive screening, the findings provide support for the validity of the examined MoCA-V subscales and for the MoCA-V's ability to distinguish TBI survivors vs controls. These results may pave the way for larger-scale investigations of the MoCA-V and for the development of more neuropsychological batteries in Vietnamese.
已经有人尝试对蒙特利尔认知评估（MoCA）进行修改，这是一种简短的认知筛查工具，以便在几个亚洲国家使用，但支持这些翻译效用的证据有限，特别是 MoCA 的越南语翻译（MoCA-V）。这项两部分研究旨在评估 MoCA-V 在越南样本中的应用。在第一阶段，我们研究了 MoCA-V 子量表与健康越南成年人（n=129）和中重度创伤性脑损伤（TBI）个体（n=80）之间常见神经心理学测试之间的关系。在第二阶段，我们探讨了 TBI 状态（TBI 与非 TBI）和人口统计学变量与 MoCA-V 表现之间的关系，并使用两个样本联合探讨了 MoCA-V 的最佳截断分数。MoCA-V 的注意力、语言和执行功能子量表分别与数字跨度测试、言语流畅性测试和轨迹形成测试相关，跨越健康参与者和 TBI 参与者。MoCA-V 的整体表现由 TBI 状态、教育和年龄预测。我们的 ROC 分析显示，截断分数为 22 可在识别 MoCA-V 测量的认知障碍方面提供最佳的敏感性（76.3%）和特异性（71.3%）权衡。除了确定认知筛查的截断分数外，这些发现还为所检查的 MoCA-V 子量表的有效性以及 MoCA-V 区分 TBI 幸存者与对照组的能力提供了支持。这些结果可能为 MoCA-V 的更大规模研究以及越南语神经心理学电池的开发铺平道路。
