The GDIT includes items with multiple response options that are either based on frequency or time, and item response theory evaluations of these could yield vital knowledge on its measurement performance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The GDIT was evaluated using Rasch analysis in a study involving 597 Swedish gamblers.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In a three\u2010dimensional Rasch model, the item response difficulty range extended from \u22121.88 to 4.06 and increased with higher time\u2010 and frequency\u2010based responses. Differential item functioning showed that some GDIT items displayed age and gender\u2010related differences. Additionally, person\u2010separation reliability indicated the GDIT could reliably be divided into three to four diagnostic levels.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The frequency\u2010 and time\u2010based item response options of the GDIT offer excellent measurement, allowing for elaborate assessment across both lower and higher gambling severity. The GDIT can be used to detect DSM\u20105 Gambling Disorder, thereby holding significance from both epidemiological and clinical standpoints. Notably, the 3\u2010item GDIT Gambling Behavior subscale also shows potential as a brief screening tool for identifying at\u2010risk gambling behavior.<\/jats:p><\/jats:sec>","DOI":"10.1002\/mpr.2018","type":"journal-article","created":{"date-parts":[[2024,3,13]],"date-time":"2024-03-13T05:48:56Z","timestamp":1710308936000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Assessing gambling disorder using frequency\u2010 and time\u2010based response options: A Rasch analysis of the gambling disorder identification test"],"prefix":"10.1002","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5348-051X","authenticated-orcid":false,"given":"Olof","family":"Molander","sequence":"first","affiliation":[{"name":"Department of Clinical Neuroscience Centre for Psychiatry Research Karolinska Institutet  Solna Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Wennberg","sequence":"additional","affiliation":[{"name":"Department of Public Health Sciences Stockholm University  Stockholm Sweden"},{"name":"Department of Global Public Health Karolinska Institutet  Solna Sweden"},{"name":"Department of Psychology Inland Norway University of Applied Sciences  Lillehammer Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicki A.","family":"Dowling","sequence":"additional","affiliation":[{"name":"School of Psychology Deakin University  Geelong Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne H.","family":"Berman","sequence":"additional","affiliation":[{"name":"Department of Clinical Neuroscience Centre for Psychiatry Research Karolinska Institutet  Solna Sweden"},{"name":"Department of Psychology Uppsala University  Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,3,12]]},"reference":[{"key":"e_1_2_10_2_1","volume-title":"Diagnostic and statistical manual of mental disorders: DSM\u2010IV","author":"American Psychiatric Association","year":"1994"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1159\/000081413"},{"key":"e_1_2_10_5_1","first-page":"340","volume-title":"Applying the Rasch model: Fundamental measurement in the human sciences","author":"Bond T.
