Conduct Disorder and Oppositional Defiant Disorder in a national sample: developmental epidemiology

Despite an expanding epidemiological evidence base, uncertainties remain over key aspects of the epidemiology of the 'antisocial' disorders in childhood and adolescence.

We used cross-sectional data on a nationally representative sample of 10,438 5-15-year-olds drawn from the 1999 British Child Mental Health Survey to examine age trends, gender ratios and patterns of comorbidity in DSM-IV Conduct Disorder (CD) and Oppositional Defiant Disorder (ODD).
