To address these gaps, we explored naturalistic outcomes for an adolescent eating disorders DHP. Adolescent participants (<jats:italic>N<\/jats:italic> = 265) completed measurements at treatment admission, discharge (<jats:italic>n<\/jats:italic> = 170), and various lengths of follow\u2010up (<jats:italic>n<\/jats:italic> = 126; <jats:italic>M<\/jats:italic><jats:sub>follow up<\/jats:sub> = 278.87\u2009days). Results from multilevel models indicated significant increases in body weight for the anorexia nervosa group throughout treatment and maintenance of increased body weight from discharge to follow\u2010up. In bulimic spectrum disorders, binge eating and purging significantly decreased from intake to discharge and did not change from discharge to follow\u2010up. Across the entire sample, eating disorder symptoms decreased from intake to discharge and did not change from discharge to follow\u2010up. Further, anxiety and depression decreased over the course of treatment and continued to decrease over the follow\u2010up period. The current investigation represents the first study to explore longitudinal DHP outcomes within adolescent bulimic spectrum eating disorders. Our findings also highlight many challenges inherent in conducting naturalistic research; it is critical that the field continue to develop solutions to the barriers inherent in conducting longitudinal research on eating disorder treatment.<\/jats:p>","DOI":"10.1002\/erv.2716","type":"journal-article","created":{"date-parts":[[2020,1,11]],"date-time":"2020-01-11T02:31:02Z","timestamp":1578709862000},"page":"199-210","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Naturalistic outcomes for a day\u2010hospital programme in a mixed diagnostic sample of adolescents with eating disorders"],"prefix":"10.1002","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9269-0747","authenticated-orcid":false,"given":"Erin E.","family":"Reilly","sequence":"first","affiliation":[{"name":"Department of Psychiatry University of California  San Diego CA"},{"name":"Department of Psychology Hofstra University  Hempstead NY"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roxanne E.","family":"Rockwell","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of California  San Diego CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana L.","family":"Ramirez","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of California  San Diego CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leslie K.","family":"Anderson","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of California  San Diego CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7349-7228","authenticated-orcid":false,"given":"Tiffany A.","family":"Brown","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of California  San Diego CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christina E.","family":"Wierenga","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of California  San Diego CA"},{"name":"VA San Diego Healthcare System  San Diego CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4478-4906","authenticated-orcid":false,"given":"Walter H.","family":"Kaye","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of California  San Diego CA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,1,10]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brat.2014.02.006"},{"key":"e_1_2_8_3_1","volume-title":"The SAGE handbook of quantitative methods in psychology","author":"Allison P.
