The Ascertain Dementia 8 questionnaire (AD8) is a brief observation checklist for detecting mild cognitive impairment (MCI) and dementia. After analyzing the reliability and validity of a self-reported Japanese version of the AD8 (AD8-J), we compared self- and informant-reported versions of the AD8-J. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; A total of 93 community residents aged 75 years or older living in Wakuya, Northern Japan, agreed to participate in this study; 35 were rated as Clinical Dementia Rating (CDR) 0 (healthy), 46 as CDR 0.5 (defined herein as MCI), and 12 as CDR 1 or above (dementia, confirmed by the DSM-IV). We examined the reliability and validity using a receiver operating characteristic (ROC) curve. We analyzed the differences between self-reported and informant-reported AD8-J using a repeated measures ANOVA. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; The self-reported AD8-J showed a satisfactory reliability (i.e., Cronbach coefficient, \u03b1 = 0.71; Guttman split half method coefficient = 0.60). For CDR 0 vs. CDR 0.5 or above, the area under the ROC curve was 0.74 and the cutoff score was 1\/2, with a sensitivity of 70.7% and a specificity of 65.7%. Analysis of the subscores of AD8 suggested that, from the early stage of dementia, the subjects showed a subjective decline in memory and interest in hobbies\/activities, as well as problems with judgment. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; It is suggested that the self-reported AD8-J was effective in detecting MCI and dementia. We could use it for detecting MCI and dementia, including in those living alone, in the primary health checkup.<\/jats:p>","DOI":"10.1159\/000514324","type":"journal-article","created":{"date-parts":[[2021,3,23]],"date-time":"2021-03-23T12:58:25Z","timestamp":1616504305000},"page":"45-50","source":"Crossref","is-referenced-by-count":9,"title":["Self-Reported Cognitive Decline Based on the Ascertain Dementia 8 Questionnaire May Be Effective for Detecting Mild Cognitive Impairment and Dementia in the Community: The Wakuya Project"],"prefix":"10.1159","volume":"11","author":[{"given":"Mari","family":"Kasai","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomohiro","family":"Sugawara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junko","family":"Takada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keiichi","family":"Kumai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7030-1496","authenticated-orcid":false,"given":"Kei","family":"Nakamura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenichi","family":"Meguro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2021,2,18]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.43.11.2412-a"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097\/00002093-200401000-00002"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s13670-018-0236-2"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3956(75)90026-6"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1002\/gps.4394"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3956(82)90033-4"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.64.5.725"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097\/WAD.0b013e3181b03277"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1037\/0882-7974.5.4.482"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1037\/0882-7974.5.3.388"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.3143\/geriatrics.52.243"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000172958.95282.2a"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000247042.15547.eb"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.3143\/geriatrics.52.61"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.140.6.566"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.148.3.6878708"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.314.7080.572"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2018.00533"}],"container-title":["Dementia and Geriatric Cognitive Disorders Extra"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/514324","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/514324","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T12:23:25Z","timestamp":1745411005000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000514324"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,2,18]]},"references-count":18,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2021,5,10]]}},"URL":"https:\/\/doi.org\/10.1159\/000514324","archive":["Portico"],"relation":{},"ISSN":["1664-5464"],"issn-type":[{"value":"1664-5464","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,2,18]]}}}
