At the whole-brain level, both childhood maltreatment and peer victimisation groups had smaller GMV than controls in a cluster comprising left post\/precentral, inferior frontal gyrus, insula, superior parietal and supramarginal gyri. The peer victimisation group alone had increased cortical thickness in a cluster comprising left superior frontal, anterior cingulate and medial orbitofrontal gyri, which was related to greater cyberbullying.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2056472422005312_sec_a5\" sec-type=\"conclusions\">\n\t    <jats:title>Conclusions<\/jats:title>\n\t    <jats:p>Early-life interpersonal stress is associated with common structural alterations of the inferior frontal-limbic, sensory and lingual regions involved in cognitive control, emotion and sensory processing. The findings of childhood-maltreatment-related reduced anterior insular GMV and peer-victimisation-related increased cortical thickness in the left medial prefrontal-anterior cingulate cluster underscore the distinctive negative effects of childhood maltreatment and peer victimisation, and suggest that peer victimisation, particularly cyberbullying, could be as detrimental as childhood maltreatment.<\/jats:p>\n\t  <\/jats:sec>","DOI":"10.1192\/bjo.2022.531","type":"journal-article","created":{"date-parts":[[2022,7,12]],"date-time":"2022-07-12T03:03:36Z","timestamp":1657595016000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":13,"title":["Examining the common and specific grey matter abnormalities in childhood maltreatment and peer victimisation"],"prefix":"10.1192","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3301-923X","authenticated-orcid":false,"given":"Lena","family":"Lim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiea Chuen","family":"Khor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"170","published-online":{"date-parts":[[2022,7,12]]},"reference":[{"key":"S2056472422005312_ref13","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291721002087"},{"key":"S2056472422005312_ref5","doi-asserted-by":"publisher","DOI":"10.1001\/archgenpsychiatry.2009.186"},{"key":"S2056472422005312_ref20","doi-asserted-by":"publisher","DOI":"10.1176\/appi.ajp.2014.13101401"},{"key":"S2056472422005312_ref2","doi-asserted-by":"publisher","DOI":"10.1176\/appi.ajp.2015.14081042"},{"key":"S2056472422005312_ref50","doi-asserted-by":"publisher","DOI":"10.1038\/npp.2017.118"},{"key":"S2056472422005312_ref19","first-page":"191","volume-title":"Social Determinants of Health and Well-Being among Young People Health Behaviour in School-Aged Children (HBSC) Study: International Report from the 2009\/2010 Survey","author":"Currie","year":"2012"},{"key":"S2056472422005312_ref34","doi-asserted-by":"publisher","DOI":"10.1037\/0022-3514.75.5.1333"},{"key":"S2056472422005312_ref53","doi-asserted-by":"publisher","DOI":"10.1093\/scan\/nsq098"},{"key":"S2056472422005312_ref11","doi-asserted-by":"publisher","DOI":"10.1016\/j.neubiorev.2016.08.011"},{"key":"S2056472422005312_ref18","first-page":"85","volume-title":"Children on Playgrounds: Research Perspectives and Applications","author":"Olweus","year":"1993"},{"key":"S2056472422005312_ref52","doi-asserted-by":"publisher","DOI":"10.1093\/scan\/nsw021"},{"key":"S2056472422005312_ref36","volume-title":"Wechsler Abbreviated Scale of Intelligence","author":"Wechsler","year":"1999"},{"key":"S2056472422005312_ref22","doi-asserted-by":"publisher","DOI":"10.1016\/j.schres.2018.11.017"},{"key":"S2056472422005312_ref54","doi-asserted-by":"publisher","DOI":"10.1016\/j.dcn.2017.02.007"},{"key":"S2056472422005312_ref33","doi-asserted-by":"publisher","DOI":"10.1037\/0022-006X.56.6.893"},{"key":"S2056472422005312_ref6","doi-asserted-by":"publisher","DOI":"10.1017\/S0954579401003042"},{"key":"S2056472422005312_ref15","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291717002392"},{"key":"S2056472422005312_ref23","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyt.2019.00696"},{"key":"S2056472422005312_ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsych.2020.05.020"},{"key":"S2056472422005312_ref35","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7610.1994.tb01284.x"},{"key":"S2056472422005312_ref27","doi-asserted-by":"publisher","DOI":"10.3389\/fnbeh.2020.00065"},{"key":"S2056472422005312_ref48","doi-asserted-by":"publisher","DOI":"10.1038\/35072584"},{"key":"S2056472422005312_ref51","doi-asserted-by":"publisher","DOI":"10.1093\/scan\/nsp007"},{"key":"S2056472422005312_ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsych.2009.04.021"},{"key":"S2056472422005312_ref12","doi-asserted-by":"publisher","DOI":"10.1176\/appi.ajp.2014.13101427"},{"key":"S2056472422005312_ref38","doi-asserted-by":"publisher","DOI":"10.1207\/s15327795jra0401_5"},{"key":"S2056472422005312_ref7","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1911264116"},{"key":"S2056472422005312_ref30","doi-asserted-by":"publisher","DOI":"10.1016\/j.chb.2015.03.065"},{"key":"S2056472422005312_ref8","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-020-80407-w"},{"key":"S2056472422005312_ref39","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-35923-1_21"},{"key":"S2056472422005312_ref17","doi-asserted-by":"publisher","DOI":"10.1176\/appi.ajp.2013.12070950"},{"key":"S2056472422005312_ref3","doi-asserted-by":"publisher","DOI":"10.3389\/fnhum.2018.00007"},{"key":"S2056472422005312_ref28","volume-title":"Childhood Trauma Questionnaire: A Retrospective Self-Report Manual.
