Note. CBCL = Child Behavior Checklist. ECBI = Eyberg Child Behavior Inventory. RCI = Reliable Change Index, which was used to determine whether the magnitude of the change exceeded the margin of measurement error. The RCI is calculated by dividing the magnitude of change between pretreatment and post-treatment scores or pretreatment and follow-up scores for each child by the standard error of the difference score.

If a RCI value is greater than 1.96, the change is considered statistically reliable.
