ABSTRACT
Objective@#To verify the criteria validity and effectiveness of the QCSS-E for screening of mild cognitive impairment (MCI) and early dementia with Alzheimer's type (DAT) among the elderly in community.@*Methods@#With stratified convenient sampling, 1 298 elderly aged 55 and over recruited from Wuxi community, who finished the clinical interviews, laboratory examination and psychological tests such as QCSS-E, ADL, MMSE, ADAS-cog, CDR, and Core Neuropsychological Test.Then they were divided into health control group(HC), MCI group and DAT group by the diagnostic criteria of Peterson’s MCI and DSM-5 AD dementia.The criteria validity and screening efficacy of QCSS-E were verified and the optimal cut off value for detecting MCI and DAT were explored.@*Results@#There were statistically significant differences in age, education level, marital status, family structure, occupation, and scores of MMSE, ADAS-cog, CNT, and QCSS-E total score and domain scores among three groups (all P<0.01). The total score and every domains score of QCSS-E were significantly correlated with test scores such as MMSE, ADAS-cog and CNT (all P<0.01). Using the total QCSS-E score to discriminate MCI from health control, the area under the curve (AUC) was 83.5%. When the cut off value was 74.5, the accuracy rate of classification was the highest (75.0%). Using the total QCSS-E score to discriminate DAT from health control, the AUC was 83.5%. When the cut off value was 64.5, the accuracy rate of classification was the highest (94.2%).@*Conclusion@#The QCSS-E has better criteria validity and higher effectiveness in screening MCI and DAT.
