Children who present with difficult behaviours due to underlying anger are commonly presented to paediatricians for help and advice. This paper gives a basic structure of how to approach the subject, by exploring whether the problems occur at home, school or both, and analysing the behaviour by focusing on antecedents, behaviour and consequences. It is important to find the underlying causes in order to know what to recommend, as this can vary from medication, anger management strategies, school-based interventions, parenting programmes or family therapy.
