Participants aged 16 or older with at least mild eating disorder symptoms were randomly assigned to four conditions: (1) Featback, an online unguided self\u2010help program, (2) chat or e\u2010mail support from a recovered expert patient, (3) Featback with expert\u2010patient support, and (4) care\u2010as\u2010usual. After a baseline assessment and intervention period of 8\u2009weeks, five online assessments were conducted over 12\u2009months of follow\u2010up. The main result constituted cost\u2010utility acceptability curves with quality\u2010of\u2010life adjusted life years (QALYs) and societal costs over the entire study duration.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>No significant differences between the conditions were found regarding QALYs, health care costs and societal costs. Nonsignificant differences in QALYs were in favor of the Featback conditions and the lowest societal costs per participant were observed in the Featback only condition (\u20ac16,741) while the highest costs were seen in the care\u2010as\u2010usual condition (\u20ac28,479). The Featback only condition had the highest probability of being efficient compared to the alternatives for all acceptable willingness\u2010to\u2010pay values.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>Featback, an internet\u2010based unguided self\u2010help intervention, was likely to be efficient compared to Featback with guidance from an expert patient, guidance alone and a care\u2010as\u2010usual condition. Results suggest that scalable interventions such as Featback may reduce health care costs and help individuals with eating disorders that are currently not reached by other forms of treatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Public significance statement<\/jats:title><jats:p>Internet\u2010based interventions for eating disorders might reach individuals in society who currently do not receive appropriate treatment at low costs. Featback, an online automated self\u2010help program for eating disorders, was found to improve quality of life slightly while reducing costs for society, compared to a do\u2010nothing approach. Consequently, implementing internet\u2010based interventions such as Featback likely benefits both individuals suffering from an eating disorder and society as a whole.<\/jats:p><\/jats:sec>","DOI":"10.1002\/eat.23763","type":"journal-article","created":{"date-parts":[[2022,6,23]],"date-time":"2022-06-23T07:36:53Z","timestamp":1655969813000},"page":"1143-1155","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Cost\u2010effectiveness of three internet\u2010based interventions for eating disorders: A randomized controlled trial"],"prefix":"10.1002","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0795-466X","authenticated-orcid":false,"given":"Pieter J.","family":"Rohrbach","sequence":"first","affiliation":[{"name":"GGZ Rivierduinen Eetstoornissen Ursula  Leiden Netherlands"},{"name":"Department of Psychiatry Leiden University Medical Center  Leiden Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5499-7139","authenticated-orcid":false,"given":"Alexandra E.","family":"Dingemans","sequence":"additional","affiliation":[{"name":"GGZ Rivierduinen Eetstoornissen Ursula  Leiden Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1131-0886","authenticated-orcid":false,"given":"Eric F.","family":"van Furth","sequence":"additional","affiliation":[{"name":"GGZ Rivierduinen Eetstoornissen Ursula  Leiden Netherlands"},{"name":"Department of Psychiatry Leiden University Medical Center  Leiden Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4117-335X","authenticated-orcid":false,"given":"Philip","family":"Spinhoven","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Leiden University Medical Center  Leiden Netherlands"},{"name":"Institute of Psychology Leiden University  Leiden Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4137-0943","authenticated-orcid":false,"given":"Joost R.","family":"van Ginkel","sequence":"additional","affiliation":[{"name":"Institute of Psychology Leiden University  Leiden Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7508-6521","authenticated-orcid":false,"given":"Stephanie","family":"Bauer","sequence":"additional","affiliation":[{"name":"Center for Psychotherapy Research University of Heidelberg  Heidelberg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5269-509X","authenticated-orcid":false,"given":"M.
