Differential assessment of childhood and adolescent aggression



DAF is one of the few instruments that measure BOTH TYPES OF AGGRESSION (proactive and reactive) – resulting from the mechanisms which children use to decode and process social information, and the way in which they choose to react. Proactively and reactively aggressive children have different deficits in this area.

Target group

DAF can be used to assess children and adolescents between 10 and 18 years old.

  • Proactive aggression – instrumental aggression aimed at domination
  • Reactive aggression – protective aggression and aggression in response to anger
  • General aggression

DAF appeals to me as an opportunity to guide specialists towards an approach to working with children displaying “aggressive” behaviours. Aggressive is in speech marks, because  sometimes, it can be defensive – and the test offers guidance in such cases too.
