All data were collected using questionnaires through face\u2010to\u2010face interviews. The logistic regression model was used to evaluate the effect factors of DASC\u201021 for dementia screening. The receiver operating characteristic curves were used to determine the optimal cut\u2010off points and the accuracy of the DASC\u201021 for dementia and mild cognitive impairment screening.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For test\u2013retest reliability, the Pearson correlation coefficient was 0.873 (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). In the criterion\u2010related validity, the DASC\u201021 scores were significantly and negatively correlated with the Mini\u2010Mental State Examination (<jats:italic>r<\/jats:italic>\u00a0=\u00a0\u22120.663, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) and the Montreal Cognitive Assessment (<jats:italic>r<\/jats:italic>\u00a0=\u00a0\u22120.565, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) scores. The results of the receiver operating characteristic analysis showed that there were different optimal cut\u2010off values for different age groups. The areas under the receiver operating characteristic curves were 95.6% and 90.3% for dementia and mild cognitive impairment screening using DASC\u201021 after considering related effect factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The DASC\u201021 was confirmed to be a valid and reliable instrument for dementia screening among Chinese community\u2010dwelling older adults.
