Recent decades have seen a steady rise in the incidence of antisocial behavior in youth. Possible direct consequences aside, such behavior is predictive of chronic emotional, educational, vocational, and emotional impairment that is associated with hundreds of millions of dollars in costs to overtaxed mental health, social services, special education, and juvenile justice systems. Written by an eminent group of international experts, Conduct and Oppositional Defiant Disorders: Epidemiology, Risk Factors, and Treatment offers the first comprehensive cutting-edge overview of all the major aspects of conduct disorder (CD) and oppositional defiant disorder (ODD) in children and adolescents. It is organized into three sections. The first summarizes classification and assessment, epidemiology and comorbidity, as well as course and outcome. The second examines factors that put children and adolescents at risk to develop CD and ODD: contextual, familial/genetic, and neuropsychological and neuroendocrine. The third presents numerous empirically supported approaches to prevention and treatment. An epilogue reviews recent progress and unresolved questions, and suggests needs for future research. Special attention is devoted to gender and developmental pathways in etiology, symptom expression, courses, and outcomes. This volume will be crucial reading for all mental health professionals whose work involves them with these exceptionally difficult clients.
