However, a detailed investigation of identity throughout ED treatment is lacking. The present longitudinal study examined identity in inpatients with an ED and explored its simultaneous change with ED symptomatology throughout treatment. A total of 225 female patients completed questionnaires at admission. From these 225 patients participating at admission (Wave 1), 110 also participated in at least one additional measurement wave, with 43.64% (n = 48) participating at admission and during treatment, 16.36% (n = 18) participating at admission and at discharge, and 40% (n = 44) participating at admission, during treatment and at discharge. Questionnaires on identity synthesis, identity confusion, identity processes, and ED symptomatology were completed. Latent growth curve modeling was used to address the research questions. Throughout treatment, a decrease in identity confusion and an increase in identity synthesis and adaptive identity processes were found. Accordingly, increases in identity synthesis and identification with commitment were related to general decreases in the drive for thinness and body dissatisfaction. Similarly, such decreases in ED symptoms were related to general decreases in identity confusion and ruminative exploration. The present study points to an increase in identity functioning throughout treatment, and longitudinal associations between identity functioning and ED symptomatology were found. Helping patients to decrease their ruminative exploration and to increase their identification with previously made life commitments and treating body\/weight concerns could both be helpful in ED treatment.<\/jats:p>","DOI":"10.3390\/nu16050591","type":"journal-article","created":{"date-parts":[[2024,2,21]],"date-time":"2024-02-21T10:52:00Z","timestamp":1708512720000},"page":"591","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Identity Functioning in Patients with an Eating Disorder: Developmental Trajectories throughout Treatment"],"prefix":"10.3390","volume":"16","author":[{"given":"Margaux","family":"Verschueren","sequence":"first","affiliation":[{"name":"De Korbeel, Child and Adolescent Psychiatric Clinic, 8500 Kortrijk, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2287-3158","authenticated-orcid":false,"given":"Laurence","family":"Claes","sequence":"additional","affiliation":[{"name":"Faculty of Psychology and Educational Sciences, KU Leuven, 3000 Leuven, Belgium"},{"name":"Child & Youth Institute, KU Leuven, 3000 Leuven, Belgium"},{"name":"Faculty of Medicine and Health Sciences, University of Antwerp, 2610 Wilrijk, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nina","family":"Palmeroni","sequence":"additional","affiliation":[{"name":"Universitair Psychiatrisch Centrum KU Leuven, 3070 Kortenberg, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leni","family":"Raemen","sequence":"additional","affiliation":[{"name":"Faculty of Psychology and Educational Sciences, KU Leuven, 3000 Leuven, Belgium"},{"name":"Child & Youth Institute, KU Leuven, 3000 Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8609-4516","authenticated-orcid":false,"given":"Philip","family":"Moons","sequence":"additional","affiliation":[{"name":"Department of Public Health and Primary Care, KU Leuven, 3000 Leuven, Belgium"},{"name":"Institute of Health and Care Sciences, University of Gothenburg, 40530 Gothenburg, Sweden"},{"name":"Department of Paediatrics and Child Health, University of Cape Town, Cape Town 7700, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6978-3002","authenticated-orcid":false,"given":"Liesbeth","family":"Bruckers","sequence":"additional","affiliation":[{"name":"I-BioStat, Data Science Institute, Hasselt University, 3500 Hasselt, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geert","family":"Molenberghs","sequence":"additional","affiliation":[{"name":"I-BioStat, Data Science Institute, Hasselt University, 3500 Hasselt, Belgium"},{"name":"I-BioStat, KU Leuven, 3000 Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2839-4027","authenticated-orcid":false,"given":"Eva","family":"Dierckx","sequence":"additional","affiliation":[{"name":"Psychiatric Hospital Alexianen Zorggroep Tienen, 3300 Tienen, Belgium"},{"name":"Faculty of Psychology and Educational Sciences, Vrije Universiteit Brussel, 1050 Brussels, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katrien","family":"Schoevaerts","sequence":"additional","affiliation":[{"name":"Psychiatric Hospital Alexianen Zorggroep Tienen, 3300 Tienen, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koen","family":"Luyckx","sequence":"additional","affiliation":[{"name":"Faculty of Psychology and Educational Sciences, KU Leuven, 3000 Leuven, Belgium"},{"name":"Child & Youth Institute, KU Leuven, 3000 Leuven, Belgium"},{"name":"Educational Unit for Professional Training and Service in the Behavioural Sciences (UNIBS), University of the Free State, Bloemfontein 9301, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"322","DOI":"10.1002\/eat.22835","article-title":"Risk and resiliency factors related to body dissatisfaction and disordered eating: The identity disruption model","volume":"51","author":"Vartanian","year":"2018","journal-title":"Int.
