30 into their respective groups (i.e., clinic-referred and non-referred) in a discriminant function analysis. 3. The DPICS II categories and summary variables of child Compliance, child Inappropriate Behavior, child Prosocial Behavior, father Inappropriate Behavior, father Direct Command Ratio, and father Total Commands will demonstrate convergent validity by each correlating significantly with ECBI intensity scores. 4. The DPICS II categories and summary variables for child behavior (i.e., Compliance, Inappropriate Behavior, Prosocial Behavior) will each demonstrate convergent validity by correlating significantly with Child Domain score on the PSI. The DPICS II summary variables for father behavior (i.e., Inappropriate Behavior, Prosocial Behavior, Direct Command Ratio, and Total Commands) will each demonstrate convergent validity by correlating significantly with the Parent Domain score on the PSI. 5. The DPICS II categories and summary variables for fathers (i.e., Direct Command Ratio, Total Commands, Inappropriate Behavior, Prosocial Behavior) will each demonstrate convergent validity by correlating significantly with PLOC-SF total scores.
