Abstract：Objective To explore the relationship between suicidal ideation and levels of depression,anxiety symptoms,rumination and self-acceptance in adolescents with depressive disorders.Methods Adolescents with depressive disorders who attended the Second Hospital of Lanzhou University from March 2023 to January 2024 were selected.Patients were assessed with Self-rating Depression Scale(SDS),Beck Scale for Suicide Ideation-Chinese Version(BSI-CV),Self-rating Anxiety Scale(SAS),Self-Acceptance Questionnaire(SAQ)and Ruminative Responses Scale(RRS).Subjects were classified into suicidal-ideation group and non-suicidal ideation group based on scores on the fourth and fifth items of BSI-CV.The differences between two groups were compared and correlation analyses and mediation effect tests were performed on the scale scores.Results A total of 90 adolescents with depressive disorders were included,68 of whom had suicidal ideation,with a detection rate of 75.56％.Correlation analysis showed that the score of BSI-CV was significantly and positively correlated with SDS,SAS,RRS,and reflection,brooding factor(P＜0.05),and was significantly and negatively correlated with SAQ,the self-acceptance and the self-evaluation factor(P＜0.05).The mediation effect test showed that depressive symptoms played a complete mediating effect between self-acceptance and suicide ideation[effect value=-0.312,95％CI(-0.507,-0.133)],while anxious symptoms played a complete mediating effect between rumination and suicide ideation[effect value=0.230,95％CI(0.037,0.442)].Conclusion This study suggests that the incidence of suicidal ideation is high in adolescents with depressive disorder,whose suicidal ideation was positively correlated with depressive symptoms,anxious symptoms and rumination,while negatively correlated with self-acceptance.Depressive symptoms and anxious symptoms respectively play a complete mediating role in the effects of self-acceptance and rumination on suicidal ideation in depressive adolescent patients with suicidal ideation.To reduce suicide risk,clinicians should pay attention to assessing and intervening ruminative thinking.In addition,psychotherapy should be applied to clinical practice to improve self-acceptance and reduce rumination.
