OBJECTIVETo explore the effects of negative life events on suicidal ideation in adolescents with depressive disorder and the mediating role of mother-child attachment， so as to provide references for reducing suicidal ideation in adolescents with depression.
METHODSA total of 145 adolescents underwent psychiatric inpatient and outpatient treatment in the First Affiliated Hospital of Chongqing Medical University From May 2020 to April 2021 and met the International Classification of Diseases， tenth edition （ICD-10） criteria for depressive episode were enrolled， and all selected individuals were assessed using the Adolescent Self-rating Life Events Checklist （ASLEC）， the Inventory of Parent and Peer Attachment （IPPA） and Beck Scale for Suicide Ideation-Chinese Version （BSI-CV）. Then Bootstrap method was used to test the mediating effect.
RESULTSBSI-CV score in adolescents with depressive disorder was positively correlated with ASLEC score （r=0.453， P<0.01）， and negatively correlated with mother-child attachment score in IPPA （r=-0.165， P<0.01）. The partial mediating effect of mother-child attachment between negative life events and suicidal ideation was significant， with a mediating effect value of 0.008， accounting for 14.55% of the total effect value （0.055）.
