Comorbidity for disruptive behavior disorders in psychiatrically hospitalized children

A variety of instruments were used to compare six groups of inpatient children: pure attention deficit disorder with hyperactivity (ADDH), pure conduct disorder (CD), pure oppositional defiant disorder (OD), ADDH+CD, and ADDH+OD, and a clinical control group who had no DBD diagnosis. Children with ADDH and CD or OD exhibited a greater degree of psychopathology. Children with CD and OD were more similar than different, indicating that perhaps a continuum of pathology exists between these diagnostic classifications.
