This study examined the relationship between Big Five personality traits, time perspective, and insomnia. In a cross-sectional study, 400 participants (227 women; age range 18\u201374 years) were administered the Big Five Inventory\u201410 items, the Zimbardo Time Perspective Inventory, and the Insomnia Severity Index (ISI). A measure of chronotype was also included for control purposes. The results show that insomniacs reported lower scores for conscientiousness and extraversion, and for past-positive (PP) and future (F) perspectives, whereas they obtained higher scores for past-negative (PN) perspectives and deviation from a balanced time perspective. The correlations confirmed these findings, but negative correlations between present-hedonistic (PH) perspective and ISI score, and between emotional stability and ISI score, were also found. The mediation analyses showed that F played an indirect role in the relationship between consciousness and ISI score, PN had an indirect effect on the relationship between emotional stability and ISI or between extraversion and insomnia, and PH had an indirect effect on the relationship between extraversion and ISI score. The current outcomes shed light on the mechanisms which serve to mediate the relationship between insomnia and personality traits.<\/jats:p>","DOI":"10.3390\/ijerph191711018","type":"journal-article","created":{"date-parts":[[2022,9,6]],"date-time":"2022-09-06T05:17:23Z","timestamp":1662441443000},"page":"11018","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Insomnia, Time Perspective, and Personality Traits: A Cross-Sectional Study in a Non-Clinical Population"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7248-4214","authenticated-orcid":false,"given":"Marco","family":"Fabbri","sequence":"first","affiliation":[{"name":"Department of Psychology, University of Campania \u201cLuigi Vanvitelli\u201d, 81100 Caserta, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessia","family":"Beracci","sequence":"additional","affiliation":[{"name":"Department of Psychology, University of Granada, 18011 Granada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2122-5183","authenticated-orcid":false,"given":"Monica","family":"Martoni","sequence":"additional","affiliation":[{"name":"Department of Experimental, Diagnostic and Specialty Medicine (DIMES), Alma Mater Studiorum, University of Bologna, 40126 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"American Psychiatric Association (2013).
