Note. AGG and RB represent Aggressive Behavior and Rule-Breaking Behavior, respectively. Raw AGG and RB scores are reported here. AGG could conceivably range from 0 to 40 for teacher-report and 0 to 36 for mother-report. RB could conceivably range from 0 to 24 for teacher-report and 0 to 34 for mother-report. Means were compared across boys and girls using independent samples t-tests,
