title: Bullying, depression, and suicidal ideation in Finnish adolescents: school survey.
abstract: OBJECTIVE
  To assess the relation between being bullied or being a bully at school, depression, and severe suicidal ideation.
  
  
  METHODS
  A school based survey of health, health behaviour, and behaviour in school which included questions about bullying and the Beck depression inventory, which includes items asking about suicidal ideation.
  
  
  METHODS
  Secondary schools in two regions of Finland.
  
  
  METHODS
  16 410 adolescents aged 14-16.
  
  
  RESULTS
  There was an increased prevalence of depression and severe suicidal ideation among both those who were bullied and those who were bullies. Depression was equally likely to occur among those who were bullied and those who were bullies. It was most common among those students who were both bullied by others and who were also bullies themselves. When symptoms of depression were controlled for, suicidal ideation occurred most often among adolescents who were bullies.
  
  
  CONCLUSIONS
  Adolescents who are being bullied and those who are bullies are at an increased risk of depression and suicide. The need for psychiatric intervention should be considered not only for victims of bullying but also for bullies.
