| Objectives With the improvement of scientific and technological level and medical technology,the problem of population aging is aggravating,and the problem of senile cognitive dysfunction caused by it is also increasingly outstanding.At present,the Montreal cognitive assessment(MoCA)as a screening tool of cognitive impairment is widely applied in clinical work.Because of MoCA is difficult for Low-educated population,in June 2014 Nasreddine published a new version,named for Montreal cognitive assessment(Montreal cognitive assessment-basic,MoCA B),and has carried on the preliminary reliability and validity verification in Thailand.But due to the different cultural backgrounds and differences in lifestyle,Guo qihao,an expert from Huashan hospital in Shanghai,signed a Chinese translation agreement with nasreddine.After a lot of discussion and translation,the Chinese version is finally worked out.This study aims to analyze the reliability and validity of Chinese Version of MoCA B in jiaxing community people aged 50 and above,and to explore its value of early diagnosis and prevention of dementia.Methods From November 2016 to April 2017,a cluster random sampling methods was adopted to extract two communities of nanhu district in jiaxing city.In these two communities,the stratified random sampling method was used to draw 360 people from the people aged 50 and above in the community.313 cases were actually completed.Mini-Mental State Examination(Hereinafter referred to as MMSE),Montreal Cognitive Assessment(Hereinafter referred to as MoCA)and Chinese Version of Montreal cognitive assessment-basic(Hereinafter referred to as Chinese Version of MoCA B)were used to assessed the cognitive function in the people.After 1 months,30 subjects were randomly selected to retest the Chinese Version of MoCA B.Finally SPSS19.0 software was used for statistical analysis of data.Results 1.The Cronbach's alpha coefficient(Cronbach's alpha)of Chinese Version of MoCA B was 0.864.After 1 month,30 inspectors were randomly selected for retest,and the retest reliability was 0.989(P=0.000).It has good consistency reliability and retest reliability.2.Correlation analysis between the scores of Chinese Version of MoCA B and MMSE showed that the total score of Chinese Version of MoCA B was significantly related to the total score of MMSE,r=0.859(P=0.000).The score of Chinese Version of MoCA B was correlated with the total score of MoCA,r=0.928(P=0.000).3.The Chinese Version of MoCA B factor(score of test item)was significantly correlated with the total score,r= 0.566-0.788(P=0.000).4.The Chinese Version of MoCA B was used to diagnose the optimal demarcation score of MCI: education years were less than 6 years,and the best demarcation was 18 points;education years were between 7-12 years,the best demarcation was 21 points;education years were higher than 12 years,the best demarcation was 23 points.Conclusions According to the Chinese cultural background and living habits of the people,the revised Chinese Version of MoCA B has good reliability and validity and higher sensitivity and specific degrees,and was more easy to operate,more suitable for the screening and diagnosis of MCI among jiaxing people aged 50 and above. |
