Psychopathology in children and adolescents with developmental disorders

Children and adolescents with developmental disorders suffer from a wide range of psychopathology. How ever; there are no published studies examining this subject exclusively in this population using recent diagnostic criteria. The primary purpose of this paper is to report on the diagnosis encountered in a clinical setting using DSM-III-R. The medical records of all individuals assessed in a specialized program during a 1-year period were reviewed looking at their demographic features, diagnoses, and target behaviors. Our sample consisted of 233 subjects and contained significantly more boys than girls. The most common psychiatric diagnoses were oppositional defiant disorder and attention deficit hyperactivity disorder: Pica, organic mental disorder NOS, and Autistic Disorder were more often encountered in individuals with low intellectual functioning. Depressive disorders, posttraumatic stress disorder; and developmental speech/language disorders were diagnosed more in high functioning subjects. The most common symptom was impulsivity. This retrospective study highlights the need for more rigorous examination of current diagnostic concepts and criteria in children and adolescents with developmental disorders. Prospective studies should be conducted with standardized instruments in clinics and community samples to provide more information on psychiatric disorders in this population.
