摘要：

目的：本文旨在研究蒙特利尔认知评估量表(MoCA)在成都市社区老年人轻度认知功能障碍(MCI)筛查中的价值，探讨该量表对社区老年人MCI筛查的最佳分界值。方法：采用简易精神状态量表(MMSE)和MoCA对成都市社区老年人进行MCI筛查，计算MoCA的信度、效度、敏感性、特异性和Youden指数，并计算适合本市老年人MCI患者的划界分。结果：参与此次社区调查并配合完成所有测试的人数为674人，其中MCI患者106人，MoCA量表的Cronbach’sα为0.852；其总分与MMSE相关系数为0.9392；MoCA以原版推荐26分为界，对MCI筛查的敏感性和特异性分别为98.11%和26.72%，Youden指数为0.2483。结论：用MoCA对成都市社区老年人认知功能的筛查是简便可行的，具有良好的信度、效度和敏感性。推荐以22分作为我市社区老年人的MCI分界值。

Objective:analyse the screening effect of MoCA for MCI,and discuss the best cutoff value,to assist inearly detection of MCI patients in old people.Methods:MCI was screened in community elderly in Chengdu by MMSEand MoCA.Results:The total number of subjects was 674,the number of MCI was 106.The Cronbach’s index was 0.852;the correlation coefficient between the MoCA and MMSE was 0.9392;the sensitivity and specificity of MoCA was 98.11%and 26.72%,and Youden’s index was 0.2483.Conclusion:The MoCA is a feasible screening tool for MCI;22 points isrecommended instead of 26 as the boundary value in community elderly in Chengdu.
