However, the psychological mechanisms linking early adversity to current suicide risk remain incompletely understood.

Participants underwent a comprehensive assessment, including sociodemographic and clinical data collection. Childhood maltreatment, suicidal ideation, and emotion regulation difficulties were evaluated using the Childhood Trauma Questionnaire (CTQ), the Beck Scale for Suicide Ideation-Chinese Version (BSI-CV), and the Difficulties in Emotion Regulation Scale (DERS), respectively. Pearson correlation analysis was used to examine associations among childhood maltreatment, difficulties in emotion regulation, and suicidal ideation. Structural equation modeling (SEM) and the bootstrap method were used to test the mediating effect, and the model was modified transparently according to modification indices.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Childhood maltreatment was significantly associated with higher levels of suicidal ideation in patients with depression. Furthermore, greater difficulties in emotion regulation were linked to increased suicidal ideation. Critically, mediation analysis indicated that emotion regulation difficulties partially mediated the relationship between childhood maltreatment and suicidal ideation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>These findings suggest that childhood maltreatment exerts both a direct effect on suicidal ideation in patients with depression and an indirect effect through the exacerbation of difficulties in emotion regulation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1776388","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T06:37:50Z","timestamp":1773643070000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["The mediating effect of emotion dysregulation on the relationship between childhood maltreatment and suicidal ideation in patients with depression"],"prefix":"10.3389","volume":"17","author":[{"given":"Lina","family":"Chen","sequence":"first","affiliation":[{"name":"School of Medicine, Jiangsu University","place":["Zhenjiang, China"]},{"name":"Peking University Sixth Hospital","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuling","family":"Feng","sequence":"additional","affiliation":[{"name":"Intravenous Infusion Therapy Center, Zhenjiang First People\u2019s Hospital","place":["Zhenjiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Wang","sequence":"additional","affiliation":[{"name":"Peking University Sixth Hospital","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nana","family":"Xiong","sequence":"additional","affiliation":[{"name":"Peking University Sixth Hospital","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lixia","family":"Li","sequence":"additional","affiliation":[{"name":"Peking University Sixth Hospital","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xia","family":"Li","sequence":"additional","affiliation":[{"name":"Peking University Sixth Hospital","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,16]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"831","DOI":"10.1007\/s10802-009-9314-4","article-title":"Mediating and moderating processes in the relation between maltreatment and psychopathology: mother-child relationship quality and emotion regulation","volume":"37","author":"Alink","year":"2009","journal-title":"J.
