Concurrent discriminative performance was evaluated via AUC, Cohen's d, signal-to-noise ratio (SNR). Sensitivity analysis excluded participants with incident depression during follow-up, and separately used all available data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All three measures demonstrated excellent cross-sectional validity (mean AUC: SMCQ-R\u2009=\u20090.883, SMCQ\u2009=\u20090.889, MMSE\u2009=\u20090.884). SMCQ-R showed numerically larger effect sizes than SMCQ (Cohen's |d|: 1.884 versus 1.742, p\u2009=\u20090.154) and higher SNR (1.659 versus 1.485, p\u2009=\u20090.327), neither significant.

Using all available data, this decline was not an artifact of the complete case restriction, and the MMSE discriminated at least as well as SMCQ-R at every assessment. SMCQ-R is regarded as an efficient complement to the MMSE rather than evidence of its superiority.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/13872877261498376","type":"journal-article","created":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T10:55:51Z","timestamp":1792148151000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Concurrent diagnostic efficiency and 8-year measurement stability of the weighted subjective memory complaints questionnaire-revised"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0892-9645","authenticated-orcid":false,"given":"Yu Jung","family":"Choi","sequence":"first","affiliation":[{"name":"Seoul National University Bundang Hospital","place":["Republic of Korea"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji Won","family":"Han","sequence":"additional","affiliation":[{"name":"Seoul National University Bundang Hospital","place":["Republic of Korea"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1103-3858","authenticated-orcid":false,"given":"Ki Woong","family":"Kim","sequence":"additional","affiliation":[{"name":"Seoul National University Bundang Hospital","place":["Republic of Korea"]},{"name":"Department of Brain and Cognitive Sciences, College of Natural Sciences, Seoul National University, Seoul, Republic of Korea"},{"name":"Department of Psychiatry, College of Medicine, Seoul National University, Seoul, Republic of Korea"},{"name":"Department of Health Science and Technology, Graduate School of Convergence Science and Technology, Seoul National University, Seoul, Republic of Korea"},{"name":"Institute of Human Behavioral Medicine, Seoul National University Medical Research Center, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,10,16]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.171.4.373"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jalz.2014.01.001"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jalz.2018.10.003"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/ane.12038"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1017\/S1355617708080363"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1080\/13607863.2015.1081150"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/1099-1166(200011)15:11<983::AID-GPS238>3.0.CO;2-5"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1159\/000096295"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1159\/000205512"},{"key":"e_1_3_3_11_2","first-page":"1","article-title":"Discrepancy between subjective memory complaints and objective memory deficits in elderly patients with depression compared to mild cognitive impairment","volume":"27","author":"Duman B","year":"2016","unstructured":"Duman B, \u00d6zel K\u0131z\u0131l ET, Baran Z, et al.
