This study evaluated the construct validity of the YSQ\u2010L2 in adults aged 35\u201397\u2009years receiving residential or outpatient geriatric, psychiatric or medical care and developed a shorter form for this population. Data from 214 participants from Dutch nursing homes and outpatient services were analysed using Item Response Theory across 16 YSQ\u2010L2 subscales. Each subscale was reduced to five items based on discrimination, difficulty, Differential Item Functioning for cognitive status and face validity. Most items showed adequate discrimination and coverage, whereas the Enmeshment scale had limited sensitivity and the Social Undesirability scale was excluded. The resulting 75\u2010item YSQ\u2010GeMS showed strong concordance with the original, providing a psychometrically robust and efficient tool for schema assessment in geriatric mental health care.<\/jats:p>","DOI":"10.1002\/cpp.70233","type":"journal-article","created":{"date-parts":[[2026,2,16]],"date-time":"2026-02-16T11:46:32Z","timestamp":1771242392000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["YSQ\u2010GeMS: Development of a Short Form of the Young Schema Questionnaire for Geriatric Mental Health Care Using Item Response Theory"],"prefix":"10.1002","volume":"33","author":[{"given":"L.","family":"Botter","sequence":"first","affiliation":[{"name":"Department of Psychiatry University of Groningen, University Medical Center Groningen  Groningen the Netherlands"},{"name":"Atlant, Markenhaven, Center for Specialized Chronic Psychiatric Nursing Home Care University of Groningen  Beekbergen the Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.\u00a0F.\u00a0M.","family":"Krabbe","sequence":"additional","affiliation":[{"name":"Department of Epidemiology University of Groningen, University Medical Center Groningen  Groningen the Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.\u00a0L.","family":"Gerritsen","sequence":"additional","affiliation":[{"name":"Department of Primary and Community Care Radboud University Medical Center, Radboud Institute for Medical Innovation  Nijmegen the Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1552-5235","authenticated-orcid":false,"given":"S.\u00a0D.\u00a0M.","family":"van Dijk","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of Groningen, University Medical Center Groningen  Groningen the Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1501-4774","authenticated-orcid":false,"given":"R.\u00a0C.\u00a0Oude","family":"Voshaar","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of Groningen, University Medical Center Groningen  Groningen the Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,2,16]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/15346501221091790"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/13607863.2016.1202891"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1017\/S1041610299005651"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/acprof:oso\/9780195377033.001.0001"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1037\/10519-153"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1300\/J083v37n01"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1300\/J074v19n01"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1521\/ijct.2013.6.2.171"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.18863\/pgy.361790"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1080\/15305058.2012.703734"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prps.2018.12.002"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2024.1369766"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.mlr.0000204008.83633.ed"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532\u20105415.2005.53221.x"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afaf066"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1017\/S1041610214000519"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10608\u2010012\u20109501\u20104"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/bjc.12324"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1080\/13607863.2017.1396579"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10608\u2010006\u20109051\u20108"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbtep.2004.08.005"},{"key":"e_1_2_8_23_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02230402"},{"key":"e_1_2_8_24_1","doi-asserted-by":"publisher","DOI":"10.1521\/pedi.2008.22.3.259"},{"key":"e_1_2_8_25_1","unstructured":"Sterk F.andM.
