title: The disruptive behavioral disorder in children and adolescents: comorbidity and clinical course.
abstract: Comorbidity, time to recovery, rate of chronicity, and probability of recurrence following recovery were studied in 51 children diagnosed with attention deficit disorder, conduct disorder, and oppositional defiant disorder. Thirty-three percent of the children had two of the above diagnoses, and one child had all three diagnoses. The mean duration of attention deficit disorder was 8 years up to the time of the interview; the mean duration of oppositional defiant disorder was 4.5 years, and the mean duration of conduct disorder was 3 years. Life-table estimates showed that 14% of the children would not have recovered 15 years after the onset of their disorder. Rates of recurrence were high following recovery from each of these disorders.
