Premorbid maladaptive personality traits were evaluated using informant versions of a brief version of the Personality Inventory for Diagnostic and Statistical manual of Mental Disorders\u20105 (PID\u20105\u2010BF), and two age\u2010specific personality measures, the Informant Personality Questionnaire (HAP), and Gerontological Personality disorder Scale. Relationships between premorbid personality and BPSD were investigated with correlational and ordinal regression analyses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>BPSD severity and distress were associated with medium sized correlations to Negative Affectivity, Antagonism and indications of personality disorder presence. The emotional distress also correlated with a medium effect with Detachment. Higher scores on maladaptive personality traits increased the odds of higher BPSD severity and distress.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Results found with age\u2010specific personality measures were in line with results found with other measures of (mal)adaptive traits. Several maladaptive personality traits had a significant relationship with the BPSD severity and associated emotional distress. We therefore encourage to implement personality assessment within BPSD treatment strategies. This way care becomes more person\u2010focused and more tailored to the specific needs of patients and caregivers.<\/jats:p><\/jats:sec>","DOI":"10.1002\/gps.5971","type":"journal-article","created":{"date-parts":[[2023,7,18]],"date-time":"2023-07-18T13:20:11Z","timestamp":1689686411000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["The role of maladaptive personality in behavioural and psychological symptoms in dementia"],"prefix":"10.1002","volume":"38","author":[{"given":"Kato","family":"Dero","sequence":"first","affiliation":[{"name":"Department of Psychology Faculty of Psychology &amp; Educational Sciences (PE) Personality and Psychopathology Research Group (PEPS) Vrije Universiteit Brussel (VUB)  Brussels Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastiaan P.
