We explored two groups: self-excluders who self-reported a motive related to addiction and those who reported a commercial motive.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>No between-group adjusted difference was found on gambling summary variables. Sessions in the two groups were poorly discriminated one from another on four different machine-learning models. More than two-thirds of the gamblers resumed poker gambling after a first self-exclusion (n=1368), half of them within the first month. No between-group difference was found for the course of gambling after the first self-exclusion. 60.1% of first-time self-excluders self-excluded again (n=822). Losses in the previous month were greater before second self-exclusions than before the first.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Reported motives for self-exclusion appear non-informative, and could be misleading. Multiple self-exclusions seem to be more the rule than the exception. The process of self-exclusion should therefore be optimised from the first occurrence to protect heavy gamblers.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/bmjopen-2018-022541","type":"journal-article","created":{"date-parts":[[2018,12,22]],"date-time":"2018-12-22T09:09:15Z","timestamp":1545469755000},"page":"e022541","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":15,"title":["Description and assessment of trustability of motives for self-exclusion reported by online poker gamblers in a cohort using account-based gambling data"],"prefix":"10.1136","volume":"8","author":[{"given":"Amandine","family":"Luquiens","sequence":"first","affiliation":[{"name":"H\u00f4pital Paul Brousse, APHP, Universit\u00e9 Paris-Saclay, Universit\u00e9 Paris-Sud, UVSQ, CESP, INSERM, Villejuif, France"},{"name":"CMAP, Ecole Polytechnique, Palaiseau, Ile-de-France, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Delphine","family":"Vendryes","sequence":"additional","affiliation":[{"name":"CMAP, Ecole Polytechnique, Palaiseau, Ile-de-France, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henri-Jean","family":"Aubin","sequence":"additional","affiliation":[{"name":"H\u00f4pital Paul Brousse, APHP, Universit\u00e9 Paris-Saclay, Universit\u00e9 Paris-Sud, UVSQ, CESP, INSERM, Villejuif, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amine","family":"Benyamina","sequence":"additional","affiliation":[{"name":"H\u00f4pital Paul Brousse, APHP, Universit\u00e9 Paris-Saclay, Universit\u00e9 Paris-Sud, UVSQ, CESP, INSERM, Villejuif, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"St\u00e9phane","family":"Gaiffas","sequence":"additional","affiliation":[{"name":"CMAP, Ecole Polytechnique, Palaiseau, Ile-de-France, France"},{"name":"LPSM UMR 8001, Universit\u00e9 Paris Diderot, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emmanuel","family":"Bacry","sequence":"additional","affiliation":[{"name":"CMAP, Ecole Polytechnique, Palaiseau, Ile-de-France, France"},{"name":"CEREMADE (CNRS UMR 7534), Universit\u00e9 Paris-Dauphine-PSL, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,12,22]]},"reference":[{"key":"2025121512351146000_8.12.e022541.1","doi-asserted-by":"crossref","DOI":"10.1186\/s12889-016-2747-0","article-title":"Understanding gambling related harm: a proposed definition, conceptual framework, and taxonomy of harms","volume":"16","author":"Langham","year":"2016","journal-title":"BMC Public Health"},{"key":"2025121512351146000_8.12.e022541.2","doi-asserted-by":"crossref","DOI":"10.1186\/s12889-015-1846-7","article-title":"Online gambling\u2019s moderators: how effective?
