In all participants (n = 26) the TPQ dimension, harm avoidance, correlated negatively with the total IGT score (R = \u20130.46). The last IGT-subtrial correlated with adventure seeking (R = 0.43), harm avoidance (R = \u20130.39) and reward dependence (R = \u20130.44). The last subtrial gives information on whether a participant has learned the IGT strategy. Multiple regression confirmed the impact of THC on the last subtrial, whereas TPQ personality traits did not additionally explain variance. <i>Conclusions:<\/i> Former indications of the IGT performance depending on the amount of cannabis consumed were replicated with an objective measurement of chronic cannabis consumption (hair THC). Multiple regression analysis argues for a stronger impact of chronic THC consumption than personality traits, but does not provide a causal relationship. Other factors (e.g. genetic) may also play a role.<\/jats:p>","DOI":"10.1159\/000189788","type":"journal-article","created":{"date-parts":[[2009,1,9]],"date-time":"2009-01-09T13:34:25Z","timestamp":1231508065000},"page":"94-98","source":"Crossref","is-referenced-by-count":28,"title":["Decision Making of Heavy Cannabis Users on the Iowa Gambling Task: Stronger Association with THC of Hair Analysis than with Personality Traits of the Tridimensional Personality Questionnaire"],"prefix":"10.1159","volume":"15","author":[{"given":"Derik","family":"Hermann","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tagrid","family":"Lem\u00e9nager","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Gelbke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helga","family":"Welzel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gisela","family":"Skopp","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karl","family":"Mann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,1,10]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2F0010-0277%2894%2990018-3"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.neuroimage.2005.02.012"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.drugalcdep.2007.02.004"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1037%2F0894-4105.21.6.778"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1530-0277.2007.00378.x"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1080%2F13803390600582446"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016%2FS0376-8716%2802%2900013-3"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00213-005-0256-4"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1192%2Fbjp.187.3.209"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1017%2FS0033291702006657"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.cogbrainres.2005.01.017"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1080%2F13803390600693615"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.drugalcdep.2004.04.009"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1530-0277.2006.00202.x"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.biopsych.2006.08.027"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.forsciint.2006.09.003"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1001%2Farchpsyc.1987.01800180093014"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1161%2F01.STR.0000163083.59201.34"}],"container-title":["European Addiction Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/189788","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/189788","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T23:03:30Z","timestamp":1745449410000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000189788"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":18,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2009,3,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000189788","archive":["Portico"],"relation":{},"ISSN":["1022-6877","1421-9891"],"issn-type":[{"type":"print","value":"1022-6877"},{"type":"electronic","value":"1421-9891"}],"subject":[],"published":{"date-parts":[[2009]]}}}
