Delusional intensity may therefore be a negative prognostic indicator, possibly warranting further treatment. Future research should examine changes in delusional intensity over longer intervals and test whether specifically targeting delusional beliefs improves treatment outcomes among individuals with AN.<\/jats:p><\/jats:sec>","DOI":"10.1002\/eat.23641","type":"journal-article","created":{"date-parts":[[2021,11,13]],"date-time":"2021-11-13T16:41:17Z","timestamp":1636821677000},"page":"215-222","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Delusional intensity as a prognostic indicator among individuals with severe to extreme anorexia nervosa hospitalized at an acute medical stabilization program"],"prefix":"10.1002","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6307-4029","authenticated-orcid":false,"given":"Kyle","family":"De Young","sequence":"first","affiliation":[{"name":"Department of Psychology University of Wyoming  Laramie Wyoming USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0687-6623","authenticated-orcid":false,"given":"Angeline","family":"Bottera","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Wyoming  Laramie Wyoming USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1950-3332","authenticated-orcid":false,"given":"Evelyna","family":"Kambanis","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Wyoming  Laramie Wyoming USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Mancuso","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Wyoming  Laramie Wyoming USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kamila","family":"Cass","sequence":"additional","affiliation":[{"name":"ACUTE Center for Eating Disorders Denver Health  Denver Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristen","family":"Lohse","sequence":"additional","affiliation":[{"name":"ACUTE Center for Eating Disorders Denver Health  Denver Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jodie","family":"Benabe","sequence":"additional","affiliation":[{"name":"ACUTE Center for Eating Disorders Denver Health  Denver Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Judy","family":"Oakes","sequence":"additional","affiliation":[{"name":"ACUTE Center for Eating Disorders Denver Health  Denver Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7587-8948","authenticated-orcid":false,"given":"Ashlie","family":"Watters","sequence":"additional","affiliation":[{"name":"ACUTE Center for Eating Disorders Denver Health  Denver Colorado USA"},{"name":"Department of Medicine University of Colorado School of Medicine  Aurora Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Craig","family":"Johnson","sequence":"additional","affiliation":[{"name":"Eating Recovery Center  Denver Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip","family":"Mehler","sequence":"additional","affiliation":[{"name":"ACUTE Center for Eating Disorders Denver Health  Denver Colorado USA"},{"name":"Department of Medicine University of Colorado School of Medicine  Aurora Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,11,13]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/107319119900600102"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/schbul\/sbw191"},{"key":"e_1_2_7_5_1","first-page":"315","volume-title":"Cognitive behavior therapy and eating disorders","author":"Bohn K.","year":"2008"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1176\/ajp.155.1.102"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1001\/archgenpsychiatry.2011.129"},{"key":"e_1_2_7_8_1","first-page":"22","article-title":"Anorexia nervosa (apepsia hysterica, anorexia hysterica)","volume":"7","author":"Gull W.
