More specifically, associations between the Dark Triad traits and two self\u2010report procrastination measures and one behavioural procrastination task (i.e., a comparison between actual and planned study time) were examined. Both psychopathy and narcissism were correlated with self\u2010report and behavioural procrastination, but Machiavellianism was unrelated to either type of procrastination. Self\u2010report and behavioural measures of procrastination were only weakly related. Our results suggest that behavioural and self\u2010report measures of procrastination capture different aspects and processes of procrastination.<\/jats:p>","DOI":"10.1002\/ijop.70088","type":"journal-article","created":{"date-parts":[[2025,7,28]],"date-time":"2025-07-28T04:23:40Z","timestamp":1753676620000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Self\u2010Report and Behavioural Procrastination in Relation to the Dark Triad Traits"],"prefix":"10.1002","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8168-092X","authenticated-orcid":false,"given":"Christopher Marcin","family":"Kowalski","sequence":"first","affiliation":[{"name":"Department of Psychology University of Northern British Columbia  Prince George British Columbia Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachel A.","family":"Plouffe","sequence":"additional","affiliation":[{"name":"Division of Psychology University of Dundee  Dundee UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2435-2217","authenticated-orcid":false,"given":"Kabir N.","family":"Daljeet","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Montreal  Montreal Quebec Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7090-0093","authenticated-orcid":false,"given":"Laura Kathleen","family":"Johnson","sequence":"additional","affiliation":[{"name":"SIGMA Assessment Systems, Inc.
