The German computer based Treatment Program for Children with Aggressive Behaviour (Soziales computerunterstütztes Training für Kinder mit aggressivem Verhalten, ScouT) aims at the therapy of children aged 6 to 12 years with peer-related aggressive behaviour, which results in a persistent impairment of the relationships to other children. Contrary to other treatment approaches, this intervention aims at the individual treatment of problem maintaining and moderating factors of aggressive behaviour. Depending on the individual problem maintaining factors the treatment aims to modify social cognitive information processing, social problem solving and behavioral social skills.
