3. Depression and Antisocial Behaviour in Adolescents : Influence of Social Status, Shaming, and Gene-Environment Interaction
Abstract : This thesis investigated (1) social status and shaming experiences in relation to aggressive behaviour and depression, and (2) gene-environment interactions between two genetic polymorphisms related to the serotonergic system – MAOA-VNTR and 5HTTLPR – and experiences of maltreatment in relation to delinquent behaviour and depression among adolescents.
