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.

ABSTRACT

Objective To explore the cognitive changes of patients with MCI using the Montreal Cognitive Assessment(MOCA) for elderly preliminarily.Methods 85 normal controls (NC),117 subjects with mild cognitive impairment (MCI) and 73 patients with Alzheimer's disease (AD) were assessed with the MOCA.Results There were significant differences among the three groups in all items of MOCA(F=258.66,P<0.01).Significant differences were observed in almost all the sub-tests between MCI group and NC group or MCI group and AD group(visuopatial F=54.86,P<0.01;naming F=17.30,P<0.01;attention F=82.50,P<0.01;language F=25,88,P<0.01;abstraction F=15.00 ,P<0.01;delayed recall F=130.49,P<0.01;orientation F=176.09,P<0.01.).The most significant differences were found in delayed recall and orientation among three groups(F=176.09,P<0.01;F=130.49,P<0.01.).At 26 cut-point,The results of screening of the MOCA agree with the gold standard of clinical diagnose for the patient with MCI.The agreement rate for observation was 0.93.The agreement rate by chance was 0.61.The Kappa was 0.85.Conclusions The MOCA appropriately define MCI,NC and AD in their cognitive function,it has good discriminant validity.The test of delayed recall and orientation may be more sensitive in the detection of the older people.The MOCA is a useful screening instrument for the patient with MCI.
