The behavior problems associated with childhood diagnoses of Attention Deficit Hyperactivity Disorder and Oppositional Defiant Disorder are frequently addressed with one of many existing methods of behavior modification. Facilities designated as Child and Adolescent Service System Programs (CASSP) are intended to treat mental and behavioral health issues for children, yet few have a predetermined method for managing the presenting disorders. Although many studies have examined the use of parent training programs as a treatment component, few have looked specifically at these programs as a part of CASSP curriculum. This study examined the use of a specific parent management method and intervention utilizing Direct Commands n the home environment, with a group of ADHD and/or ODD children receiving services through a CASSP system of care in western Pennsylvania. Fifty parents completed pre- and post-intervention questionnaires reporting their perception of their child’s behaviors and whether or not the direct command method was effective in managing behaviors. An experimental group was selected at random to utilize the intervention. It was found that the parents who utilized the Direct Command intervention observed improved behavior in their children, while the parents who did not use the intervention observed little or no change in their children's behaviors.
