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.

ABSTRACT: Exposure to campus suicide poses a significant threat to adolescent mental health. 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 → PT → AS → DS) was significant and was identified as the mos
