DPICS II categories were shown to have acceptable reliability estimates. The DPICS II also demonstrated convergent validity by accounting for a significant proportion of the variance in the scores on the ECBI, the PLOC, and the parent and child scales of the PSI. In addition, significant differences in the expected direction were found on all of the DPICS II summary variables with the exception of child Prosocial Behavior. Finally, a discriminant function analysis was performed on selected DPICS II summary variables (i.e., child Compliance, child Prosocial Behavior, child Inappropriate Behavior, parent Total Command, parent Prosocial Behavior, parent Direct Command Ratio, and parent Inappropriate Behavior) to demonstrate that these variables could distinguish between the clinic and nonclinic samples. The DPICS II summary variables resulted in an overall correct classification rate of 86.6%. It is noteworthy that the correct classification rate was not altered when SES was entered into the analysis.
Specific Aims
The specific aims of this study were to investigate whether the DPICS II is a
reliable and valid tool for assessing father-child interactions; to provide normative data on father-child interactions for DPICS II; and to further our understanding of father-child interactions in families of normal and conduct-disordered children. This was accomplished by comparing self-report measures and videotaped interactions of non-referred father-child dyads to father-child dyads in which the child was referred to a psychology clinic for behavior problems and diagnosed with Oppositional Defiant Disorder. Reliability was assessed using kappa estimates and intraclass correlations. Discriminative validity was examined by evaluating the degree to which the DPICS II categories discriminate between
