The authors describe the design and reliability of a rating scale that
measures aggressive behaviors in adults and children. On the Overt
Aggression Scale (OAS), aggression is divided into four categories: verbal
aggression, physical aggression against objects, physical aggression
against self, and physical aggression against others. In addition, specific
interventions related to each aggressive event can be recorded on the OAS.
The clinical and research applications of this scale are discussed.
