We examined genetic and environmental associations between sleep and four maladaptive domains (MDs)\u2014Negative Affectivity, Detachment, Disinhibition, and Psychoticism\u2014within the framework of the DSM\u20105 Alternative Model of Personality Disorders (AMPD). We estimated phenotypic, genetic, and environmental variance and covariance using a twin study approach. Phenotypically, the four MDs showed small associations with sleep duration, medium associations with sleep efficiency, and large associations with sleep quality. A similar pattern was observed in genetic correlations, with Negative Affectivity and Detachment consistently showing the strongest associations. Multilevel Regression results based on the co\u2010twin control design indicated that genetic factors only partially account for these relations. Whilst previous research has extensively focused on adaptive personality traits predicting sleep, our study highlights the importance of maladaptive traits as meaningful predictors of sleep health.<\/jats:p>","DOI":"10.1111\/jsr.70242","type":"journal-article","created":{"date-parts":[[2025,11,14]],"date-time":"2025-11-14T14:12:26Z","timestamp":1763129546000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Sleep and Maladaptive Personality Traits: A Twin Study"],"prefix":"10.1111","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-4395-0481","authenticated-orcid":false,"given":"Ziyu","family":"Ren","sequence":"first","affiliation":[{"name":"Department of Psychology University of Minnesota\u2014Twin Cities  Minneapolis Minnesota USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jarrod M.","family":"Ellingson","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of Colorado Anschutz Medical Campus  Aurora Colorado USA"},{"name":"Institute for Behavioral Genetics University of Colorado Boulder  Boulder Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Hopfer","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of Colorado Anschutz Medical Campus  Aurora Colorado USA"},{"name":"Institute for Behavioral Genetics University of Colorado Boulder  Boulder Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert F.","family":"Krueger","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Minnesota\u2014Twin Cities  Minneapolis Minnesota USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zlatan","family":"Krizan","sequence":"additional","affiliation":[{"name":"Department of Psychology Iowa State University  Ames Iowa USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kristian E.","family":"Markon","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Minnesota\u2014Twin Cities  Minneapolis Minnesota USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deniz S.","family":"Ones","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Minnesota\u2014Twin Cities  Minneapolis Minnesota USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zo\u00eb","family":"Panchal","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of Colorado Anschutz Medical Campus  Aurora Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4424-5301","authenticated-orcid":false,"given":"J.
