Note. CBCL = Child Behavior Checklist; BDI-II = Beck Depression Inventory-II; PSI-SF = Parenting Stress Index- Short Form.
The Reliable Change Index (RCI) was used to determine whether the magnitude of change exceeded the margin of measurement error. The RCI was calculated by dividing the magnitude of change between the Time 1 and Time 2 scores for each individual by the stand error of the sample difference scores. RCIs greater than 1.96 were statistically significant.
A child was determined to have made a clinically significant change if the child’s score was in the clinically significant range ant Time 1 assessment and in the normal range at Time 2 assessment, and the change in the individual score from Time 1 to time 2 was statistically reliable as defined using the RCI.
