Measuring children's aggression with teachers' predictions of peer nominations.

Peer nominations have been used very successfully to assess aggressive dispositions in children but are costly to administer in situations in which a subject population is scattered among many classrooms.In the present study, the authors evaluated an alternative measure, the Teacher Prediction of Peer-Nominated Aggression.This measure proved to be highly reliable and valid-a better predictor of peer nominations of aggression than teacher checklist ratings of aggression.The teachers' predictions of peer-nominated aggression also displayed the same pattern of interrelations and gender differences as actual peer nominations of aggression.Finally, the teachers' predictions of aggression were more accurate than their predictions of other behaviors.
