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.Abstract: 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 proieets have a satisfied amount of factor loading(≥0.4).There were significant diffeFences in the score of M@T among the different cognitive level groups with good discriminant 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. 相似文献
