Childhood abuse is a prominent risk factor for PTSD and ED symptoms both individually and as a comorbid syndrome (PTSD\u2013ED). There may be a functional association between comorbid PTSD\u2013ED symptoms whereby disordered eating behaviors are used to avoid trauma\u2010related thoughts and feelings. The current study used a network analytic approach to examine key associations between PTSD and ED symptom subscales (i.e., PCL\u20105 and EPSI, respectively) in a community sample of 120 adults who endorsed at least one experience of childhood abuse (i.e., physical, sexual, or emotional abuse; witnessing domestic violence). Participants completed an anonymous online survey using Amazon's Mechanical Turk Prime. We used three network analysis indices (i.e., strength centrality, key players, and bridge symptoms) to identify symptoms that may maintain the comorbid PTSD\u2013ED network. The results indicated that reexperiencing symptoms had the highest strength centrality in the PTSD\u2013ED network and bridged the PTSD and ED clusters. For ED, cognitive restraint was a bridge to all PTSD symptoms. Hyperarousal, negative alterations in cognitions and mood (NACM), and purging were key players, indicating they are integral to the network structure. If replicated in prospective studies, these results may indicate that reexperiencing and cognitive restraint are core drivers of PTSD\u2013ED comorbidity, whereas hyperarousal, NACM, and purging may be downstream consequences maintaining the comorbid condition. Concurrent treatments that address PTSD and ED symptoms simultaneously may result in the best outcomes.<\/jats:p>","DOI":"10.1002\/jts.22644","type":"journal-article","created":{"date-parts":[[2020,12,28]],"date-time":"2020-12-28T23:41:26Z","timestamp":1609198886000},"page":"665-674","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Network Analysis of Posttraumatic Stress and Eating Disorder Symptoms in a Community Sample of Adults Exposed to Childhood Abuse"],"prefix":"10.1002","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4015-2071","authenticated-orcid":false,"given":"Rachel E.","family":"Liebman","sequence":"first","affiliation":[{"name":"Faculty of Health York University Toronto Canada"},{"name":"Department of Psychology Ryerson University Toronto Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kendra R.","family":"Becker","sequence":"additional","affiliation":[{"name":"Eating Disorders Clinical and Research Program Massachusetts General Hospital Boston Massachusetts USA"},{"name":"Department of Psychiatry Harvard Medical School Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathryn E.","family":"Smith","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences University of Southern California, Los Angeles Los Angeles California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Cao","sequence":"additional","affiliation":[{"name":"Sanford Center for Biobehavioral Research Fargo North Dakota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ani C.","family":"Keshishian","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Louisville Louisville Kentucky USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ross D.","family":"Crosby","sequence":"additional","affiliation":[{"name":"Sanford Center for Biobehavioral Research Fargo North Dakota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kamryn T.","family":"Eddy","sequence":"additional","affiliation":[{"name":"Eating Disorders Clinical and Research Program Massachusetts General Hospital Boston Massachusetts USA"},{"name":"Department of Psychiatry Harvard Medical School Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer J.","family":"Thomas","sequence":"additional","affiliation":[{"name":"Eating Disorders Clinical and Research Program Massachusetts General Hospital Boston Massachusetts USA"},{"name":"Department of Psychiatry Harvard Medical School Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,12,28]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.22783"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.janxdis.2018.07.004"},{"issue":"1","key":"e_1_2_6_4_1","first-page":"11","article-title":"The network approach to posttraumatic stress disorder: a systematic review","author":"Birkeland M.
