We examined self\u2010informant agreement in PD screening among older adults (\u226560\u2009years) using the Gerontological Personality disorders Scale (GPS). Potential differences such as who reports more personality pathology on a PD screener (i.e., GPS), item accessibility and the effect of relational aspects were studied as well. Data of 326 older adult\u2010informant dyads, of which the older adults were sampled from five general practices in the Netherlands, were used. Results indicate that self\u2010informant agreement ranged from <jats:italic>r<\/jats:italic>\u2009=\u20090.26\u20130.73, with lower concordance on the GPS\u2010subscale measuring intrapersonal aspects of personality pathology. Informants were more sensitive to habitual pathological personality features than older adults. Two GPS items showed differential item functioning across self\u2010 and informant\u2010report. Of relational aspects, only congeniality affected the GPS\u2010iv scores; lower ratings on congeniality were associated with higher GPS\u2010iv scores (i.e., higher reporting of personality problems).<\/jats:p>","DOI":"10.1002\/pmh.1592","type":"journal-article","created":{"date-parts":[[2023,10,3]],"date-time":"2023-10-03T03:40:43Z","timestamp":1696304443000},"page":"32-42","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Personality disorders in older adults: Differences in self\u2010informant ratings"],"prefix":"10.1002","volume":"18","author":[{"given":"Krystle A.
