A new questionnaire on aggression was constructed. Replicated factor analyses yielded
4 scales: Physical Aggression, Verbal Aggression, Anger, and Hostility. Correlational
analysis revealed that anger is the bridge between both physical and verbal aggression
and hostility. The scales showed internal consistency and stability over time. Men
scored slightly higher on Verbal Aggression and Hostility and much higher on Physical
Aggression. There was no sex difference for Anger. The various scales correlated differently
with various personality traits. Scale scores correlated with peer nominations of
the various kinds of aggression. These findings suggest the need to assess not only
overall aggression but also its individual components.
