Objective:To analyze the influence of adversity beliefs and social support on depressive symptoms among adoles-cents in Chengdu and provide a reference for improving the mental health of adolescents in this region.Methods:A questionnaire survey was conducted among 4873 adolescents aged 10-19 from the Chengdu Positive Children's Growth Cohort using the Children's Depression Inventory(CDI),the Adolescent Social Support Scale,and the Beliefs about Adversity Scale.The survey took place from June to July 2022,employing a multi-stage stratified cluster sampling method.Pearson correlation analysis,multiple stepwise regression analysis,and mediation effect models were used to analyze the impact of adversity beliefs and social support on depres-sive symptoms.Results:Adversity beliefs(β=-0.40,P＜0.001)and social support(β=-0.41,P＜0.001)both had a significant negative impact on depressive symptoms among adolescents in Chengdu.Social support partially mediated the relationship between adversity beliefs and depressive symptoms,with a mediation effect value of 40%.Additionally,social support moderated the rela-tionship between adversity beliefs and depressive symptoms(β=0.11,t=2.779,P＜0.001).Conclusion:Adolescents'depressive symptoms are influenced by adversity beliefs,and social support plays a partial mediating and moderating role in this relationship.Family,school,and societal efforts should focus on enhancing adolescents'ability to cope with adversity and providing increased so-cial support to reduce the risk of depressive symptoms.
