This paper focuses on children who bully at school, and specifically on the role of parenting and family functioning in bullying and examines early intervention strategies to address bullying behaviour. Children who bully often have a wide range of conduct problems and display high levels of depressive, aggressive and delinquent behaviour. Bullying is considered to be a possible precursor for criminal behaviours in adolescence and adulthood. Children who bully are at greater risk for later depression by 30%. Families pay an important role in bullying behaviours. Children who bully require targeted approaches and support to change their behaviour. Those who chronically bully may also have mental health issues which require addressing. Effective and early treatment may decrease the likelihood of these children experiencing later adverse life outcomes.
