Frequencies of T-Score Differences Between Achenbach Child Behavior Checklist and Teacher’s Report Form Summary Scales

A table is provided giving observed difference frequencies for caregiver versus teacher ratings of children on the Child Behavior Checklist and Teacher’s Report Form Internalizing, Externalizing, and Total Problems scales per the original normative samples. The table permits accurate evaluation of the empirical rarity of specific cross-informant rating discrepancies. This methodology provides a more direct assessment of interrater summary score differences than does the Q-correlation statistic reported in the Achenbach System of Empirically Based Assessment scoring program.
