The directed acyclic graph model was employed to analyse a large longitudinal data-set of Chinese children and adolescents exposed to a destructive earthquake. It was found that intrusion symptoms were first activated by trauma exposure, and subsequently activated other PTSD symptoms. The data are consistent with the idea that symptoms may form a self-sustaining dynamic network by interacting with each other to promote or maintain the chronicity of PTSD. The findings advance the current understanding about the psychopathological processes of PTSD, and inform further research and clinical practices on post-traumatic psychopathology.<\/jats:p>","DOI":"10.1192\/bjo.2023.615","type":"journal-article","created":{"date-parts":[[2023,12,4]],"date-time":"2023-12-04T08:08:14Z","timestamp":1701677294000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":5,"title":["Revealing the psychopathological pathway linking trauma to post-traumatic stress disorder: longitudinal network approach"],"prefix":"10.1192","volume":"10","author":[{"given":"Chen","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0320-7395","authenticated-orcid":false,"given":"Chengqi","family":"Cao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruojiao","family":"Fang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1459-3412","authenticated-orcid":false,"given":"Li","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Denny","family":"Borsboom","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"170","published-online":{"date-parts":[[2023,12,4]]},"reference":[{"key":"S2056472423006154_ref8","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v035.i03"},{"key":"S2056472423006154_ref5","doi-asserted-by":"publisher","DOI":"10.1080\/10705511.2022.2056039"},{"key":"S2056472423006154_ref11","doi-asserted-by":"publisher","DOI":"10.1037\/0021-843X.101.3.452"},{"key":"S2056472423006154_ref2","doi-asserted-by":"publisher","DOI":"10.1007\/s00127-016-1319-z"},{"key":"S2056472423006154_ref4","doi-asserted-by":"publisher","DOI":"10.1080\/20008198.2019.1700614"},{"key":"S2056472423006154_ref1","first-page":"98","volume-title":"Handbook of PTSD: Science and Practice","author":"Bryant","year":"2007"},{"key":"S2056472423006154_ref3","doi-asserted-by":"publisher","DOI":"10.1002\/wps.20375"},{"key":"S2056472423006154_ref9","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v048.i04"},{"key":"S2056472423006154_ref6","doi-asserted-by":"publisher","DOI":"10.1007\/s11920-004-0048-2"},{"key":"S2056472423006154_ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.cpr.2015.12.003"},{"key":"S2056472423006154_ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.janxdis.2020.102319"}],"container-title":["BJPsych Open"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S2056472423006154","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,12,4]],"date-time":"2023-12-04T08:08:16Z","timestamp":1701677296000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S2056472423006154\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,12,4]]},"references-count":11,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2024,1]]}},"alternative-id":["S2056472423006154"],"URL":"https:\/\/doi.org\/10.1192\/bjo.2023.615","relation":{},"ISSN":["2056-4724"],"issn-type":[{"value":"2056-4724","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,12,4]]},"assertion":[{"value":"Copyright \u00a9 The Author(s), 2023.
