Core symptoms can be statistically identified using network analysis. Existing ED network studies support that shape and weight overvaluation are the core ED psychopathology, yet no studies have estimated AN core psychopathology and concerns exist about the replicability of network analysis findings. The current study estimated ED symptom networks among people with anorexia nervosa (AN) and bulimia nervosa (BN) and among a combined group of people with AN and BN.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Participants were girls and women with AN (<jats:italic>n =<\/jats:italic>604) and BN (<jats:italic>n =<\/jats:italic>477) seeking residential ED treatment. ED symptoms were assessed with the Eating Disorder Examination\u2010Questionnaire (EDE\u2010Q); 27 of the EDE\u2010Q items were included as nodes in symptom networks. Core symptoms were determined by expected influence and strength values.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In all networks, desiring weight loss, restraint, shape and weight preoccupation, and shape overvaluation emerged as the most important symptoms. In addition, in the AN and combined networks, fearing weight gain emerged as an important symptom. In the BN network, weight overvaluation emerged as another important symptom.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>Findings support the cognitive\u2013behavioral premise that shape and weight overvaluation are at the core of AN psychopathology. Our BN and combined network findings provide a high degree of replication of previous findings. Clinically, findings highlight the importance of considering shape and weight overvaluation as a severity specifier and primary treatment target for people with EDs.<\/jats:p><\/jats:sec>","DOI":"10.1002\/eat.22871","type":"journal-article","created":{"date-parts":[[2018,4,25]],"date-time":"2018-04-25T15:50:44Z","timestamp":1524671444000},"page":"668-679","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":113,"title":["Core psychopathology in anorexia nervosa and bulimia nervosa: A network analysis"],"prefix":"10.1002","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1481-5078","authenticated-orcid":false,"given":"Lauren N.","family":"Forrest","sequence":"first","affiliation":[{"name":"Department of Psychology Miami University Oxford Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Payton J.","family":"Jones","sequence":"additional","affiliation":[{"name":"Department of Psychology Harvard University Cambridge Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shelby N.","family":"Ortiz","sequence":"additional","affiliation":[{"name":"Department of Psychology Miami University Oxford Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0832-0028","authenticated-orcid":false,"given":"April R.","family":"Smith","sequence":"additional","affiliation":[{"name":"Department of Psychology Miami University Oxford Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,4,25]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/mpr.329"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/erv.637"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-clinpsy-050212-185608"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1037\/abn0000306"},{"issue":"3","key":"e_1_2_6_7_1","doi-asserted-by":"crossref","first-page":"260","DOI":"10.1002\/eat.20681","article-title":"The factor structure of the Eating Disorder Examination in clinical and community samples","volume":"43","author":"Byrne S.
