Empirically based assessment of the behavioral/emotional problems of 2- and 3- year-old children

Normative data are presented for 570 children on newly revised versions of the Conners Parent and Teacher Rating Scales. Symptom ratings were factor analyzed and structures compared favorably with those obtained using earlier versions of the questionnaires. Interrater correlations (mother-father, parent-teacher) were also reported. Age and sex effects were found to be significant determinants of children's scores, while social class effects were nonsignificant.
