摘　　要：目的初步探讨记忆改变测试量表（M@T）中文版在我国老年人群中应用的信度、效度和可行性。方法以横断面调查测试的形式测查220名某社区老年人，其中明确诊断为轻度认知功能损害（MCI）患者39例、阿尔茨海默病（AD）患者20例，认知正常者161名，用内部一致性、内容效度、标准效度、主成分和因子分析、影响因素等对测试结果进行评价。结果M@T筛查量表克朗巴赫α系数（Cronbach α）为0．818。各项目得分与总分相关系数为0．5—0．9；MMSE与M@T相关系数为0．933。因子分析提取5个公因子，能解释总方差的69．449％，且各项目在相应因子上有较满意的因子载荷量（≥0．4）。不同认知水平组M@T得分[认知正常组（39．0±3．7）分、MCI组（29．0±3．7）分、AD组（16．9±3．7）分]差异有统计学意义（F=498．419，P〈0．05）。不同性别、年龄、职业、文化程度人群的M@T得分差异无统计学意义。结论中文版M@T具有较好的信效度和可行性，基本不受性别、年龄、职业、文化程度等因素的影响。Objectives To study the reliability, validity and feasibility of the Chinese version of memory alteration test （ M@T）. Methods Cross-sectional survey with a convenience sample was employed to interview 220 elderly people over 60 years old, 39 patients with mild cognitive impairment（MCI） ,20 with Alzheimer＇ s disease（AD）, and 161 normal cognitive elderly. The survey was then evaluated with internal consistency, content validity, criterion validity, principal component/factor analysis and influencing factors. Results A Cronbach＇ s α coefficient of 0. 818 was obtained in M@ T. The correlation coefficients which were the score of the subtest and the total were 0. 5-0. 9. The correlation coefficient of the scores of the Mini-mental State Examination （MMSE） and the M@ T was 0. 933. The 5 factors were extracted with the factor analysis, which could explain the total variance of 69. 449%, and the corresponding factors of the projects have a satisfied amount of factor loading （ ≥0. 4）. There were significant differences in the score of M@ T among the different cognitive level groups with good diseriminant validity（ cognitive normal group： 39.0±3.7, MCI group： 29.0 ±3.7, AD group：16.9 ±3.7;F=498.419,P〈0.05）. There were no significant differences in the score of M@ T among the different gender, age, occupation and education level groups. Conclusions The Chinese version of M@ T has good reliability and validity and feasibility. The score of the M@ T is not affected by gender, age, occupation, education level and other factors.
