Brief summary

The purpose of this study is to modify behavior therapy so that it is optimized for children with conduct problems and callous-unemotional traits by emphasizing reward components and de-emphasizing punishment components.

Detailed description

Several studies have demonstrated that standard behavioral treatments do not appear to be sufficient for children with conduct problems (CP) and callous-unemotional (CU) traits. Other research suggests that children with CPCU are less responsive to punishments as evaluated using controlled laboratory tasks. Based on these two sets of findings, it was hypothesized that behavioral treatment modified to emphasize reward and de-emphasize punishments would be advantageous when used to treat children with CPCU. This hypothesis was tested in a treatment development study that had three phases. During phase 1, which occurred in 2010, the intervention was planned and treatment procedures and manuals were developed. During phase 2, which occurred in 2011, a pilot study was conducted in which the intervention was tested in an iterative manner in a group of 12 children with conduct problems and callous-unemotional traits. In phase 3, a larger trial was conducted using a cross over design, with one-half of participants getting standard behavioral treatment for four weeks followed by modified behavioral treatment for four weeks and remaining participants receiving treatments in the reverse order.Treatments were evaluated using parent ratings, counselor ratings, and frequency counts of behavior during treatments.

Interventions

BEHAVIORALReward-Emphasized Treatment

Overall Sample
Summer treatment program: Intensive behavioral treatment delivered in a summer camp setting. During one block of four weeks, participants received modified behavioral treatment (MBT) that emphasized rewards and de-emphasized punishments. During another block of four weeks, participants received standard behavior treatment (SBT) that balanced reward and punishment. Order of treatment blocks was counter-balanced across participants, and primary analyses were within-subject comparisons. Therefore, we report demographics for the full sample.
