Studies have shown that personality traits, particularly neuroticism, act as factors that predispose to and potentially perpetuate insomnia; however, there is still no consensus in the literature regarding these relationships considering their mechanisms. A total of 595 participants answered the Insomnia Severity Index, Revised Neuroticism\u2010Extroversion\u2010Openness (NEO) Five\u2010Factor Inventory, Hospital Anxiety and Depression Scale, questions of the\n                    <jats:italic>Diagnostic and Statistical Manual of Mental Disorders<\/jats:italic>\n                    (fifth edition), and a sociodemographic questionnaire. Descriptive analysis, correlations and stepwise linear regression were used to assess the associations between the five personality traits and insomnia severity. Mediation and moderation analyses were performed to evaluate the mechanisms underlying the association between insomnia severity and neuroticism. There was a direct negative association between insomnia severity and openness to experience and an indirect positive association between insomnia severity and neuroticism. Anxiety was identified as a mediator and depression as a moderator of the association between insomnia severity and neuroticism. The neuroticism and openness to experience personality traits are significant predictors of insomnia severity. Openness to experience appears to be a protective factor against insomnia. Longitudinal studies are needed to confirm our findings. These results may contribute to the development of new psychological and behavioural protocols for the treatment of insomnia.\n                  <\/jats:p>","DOI":"10.1111\/jsr.70003","type":"journal-article","created":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T23:00:42Z","timestamp":1740006042000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Personality traits and insomnia: direct and anxiety\u2010mediated associations"],"prefix":"10.1111","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4162-0970","authenticated-orcid":false,"given":"B\u00e1rbara Ara\u00fajo","family":"Conway","sequence":"first","affiliation":[{"name":"Institute of Psychiatry University of S\u00e3o Paulo  S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marwin Machay Indio do Brasil","family":"do Carmo","sequence":"additional","affiliation":[{"name":"University of California  Davis California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helder Sergio Lira Soares","family":"Filho","sequence":"additional","affiliation":[{"name":"Institute of Psychiatry University of S\u00e3o Paulo  S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea Cec\u00edlia","family":"Toscanini","sequence":"additional","affiliation":[{"name":"Institute of Psychiatry University of S\u00e3o Paulo  S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rosa","family":"Hasan","sequence":"additional","affiliation":[{"name":"Institute of Psychiatry University of S\u00e3o Paulo  S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcela Mansur","family":"Alves","sequence":"additional","affiliation":[{"name":"Universidade Federal de Minas Gerais  Belo Horizonte Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2212-4608","authenticated-orcid":false,"given":"Renatha","family":"El Rafihi\u2010Ferreira","sequence":"additional","affiliation":[{"name":"Institute of Psychiatry University of S\u00e3o Paulo  S\u00e3o Paulo Brazil"},{"name":"Department of Clinical Psychology University of S\u00e3o Paulo  S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,2,19]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.heliyon.2019.e01939"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/jsr.14031"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596.dsm12"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1590\/s1516-44462000000300003"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/s1389-9457(00)00065-4"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12160-012-9454-6"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1590\/S0034-89101995000500004"},{"key":"e_1_2_11_9_1","volume-title":"Adaptation and validation of the Insomnia Severity Index (ISI): population characteristics, normative values and associated factors","author":"Castro L.
