Validity of rating scales in assessing aggressive behavior in classroom settings

The teachers of 35 boys attending a Lehigh University-based laboratory school for emotionally and behaviorally disturbed children completed rating scales designed to assess aggressive behavior in children. Children also completed similar self-report instruments. Frequency counts of aggressive outbursts and outburst durations were recorded by teachers over a 4-week period. The results of the study found significant correlations among teacher-completed and child-completed measures. The relationships between child-completed measures, one of the teacher measures, and the direct observation measure were not significant. One teacher-completed measure, but no child-completed measures, had significant correlations with aggressive outbursts and durations. The implications for behavioral assessment are discussed.
