While childhood psychological abuse (CPA) is a known vulnerability factor for depression, the mechanisms linking this early adversity to depressive symptoms (DS) following acute trauma remain unclear. This study aimed to test a chain mediation model where CPA contributes to DS through the sequential effects of psychological trauma (PT) and anxiety symptoms (AS). In a cross-sectional study of 1603 adolescents exposed to a campus suicide event, participants completed self-report measures for CPA, PT, AS, and DS. Chain mediation analysis revealed a significant direct effect of CPA on DS. More importantly, the hypothesized chain mediation pathway (CPA \u2192 PT \u2192 AS \u2192 DS) was significant and was identified as the most substantial indirect route. A key asymmetry emerged: the direct effect of CPA on DS remained robust, whereas its direct effect on AS became non-significant when controlling for DS. These findings suggest that CPA establishes a specific vulnerability to depression that, when activated by an acute stressor, initiates a pathological cascade. Interventions for suicide-exposed youth should be trauma-informed, prioritizing those with a CPA history and targeting emergent anxiety to interrupt the progression to severe depression.<\/jats:p>","DOI":"10.3390\/bs15111595","type":"journal-article","created":{"date-parts":[[2025,11,20]],"date-time":"2025-11-20T13:25:27Z","timestamp":1763645127000},"page":"1595","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Effect of Childhood Psychological Abuse on Depressive Symptoms in Adolescents Exposed to Campus Suicide: The Chain Mediating Role of Psychological Trauma and Anxiety Symptoms"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-2693-544X","authenticated-orcid":false,"given":"Tingting","family":"Tan","sequence":"first","affiliation":[{"name":"Key Research Base of Humanities and Social Sciences of the Ministry of Education, Academy of Psychology and Behavior, Tianjin Normal University, Tianjin 300387, China"},{"name":"Faculty of Psychology, Tianjin Normal University, Tianjin 300387, China"},{"name":"Mental Health Education Center, Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3213-0275","authenticated-orcid":false,"given":"Jiawei","family":"Zhao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Cognitive Neuroscience and Learning, IDG\/McGovern Institute for Brain Research, Beijing Normal University, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1972-8758","authenticated-orcid":false,"given":"Mengxuan","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Communication Sciences and Disorders, The University of Texas Rio Grande Valley, Edinburg, TX 78539, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-6534-8234","authenticated-orcid":false,"given":"Xinyue","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Cognitive Neuroscience and Learning, IDG\/McGovern Institute for Brain Research, Beijing Normal University, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8149-0192","authenticated-orcid":false,"given":"Xinchun","family":"Liu","sequence":"additional","affiliation":[{"name":"Mental Health Education Center, Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3450-2938","authenticated-orcid":false,"given":"Lili","family":"Zhang","sequence":"additional","affiliation":[{"name":"Tianjin No. 55 High School, Tianjin 300070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-4965-4878","authenticated-orcid":false,"given":"Jie","family":"Wu","sequence":"additional","affiliation":[{"name":"Key Research Base of Humanities and Social Sciences of the Ministry of Education, Academy of Psychology and Behavior, Tianjin Normal University, Tianjin 300387, China"},{"name":"Faculty of Psychology, Tianjin Normal University, Tianjin 300387, China"},{"name":"Tianjin Key Laboratory of Student Mental Health and Intelligence Assessment, Tianjin 300387, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1016\/j.jpsychires.2017.01.017","article-title":"Prevalence of exposure to suicide: A meta-analysis of population-based studies","volume":"88","author":"Andriessen","year":"2017","journal-title":"Journal of Psychiatric Research"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"502","DOI":"10.1016\/j.jad.2023.01.041","article-title":"The mediating effect of stress reactivity in the 18-year bidirectional relationship between generalized anxiety and depression severity","volume":"325","author":"Barber","year":"2023","journal-title":"Journal of Affective Disorders"},{"key":"ref_3","unstructured":"Beck, A.
