Children and adolescents deemed "out of control" by parents and educators are among the most commonly referred for professional care. Increased professional and public interest in these children has sparked a proliferation of research focusing on etiologic, diagnostic, and research issues of disruptive behavior disorders. Accordingly, the empirical knowledge base has grown rapidly in richness and complexity. This important volume brings clinical practice up to date with these many new advances in an unusually accessible format, presenting an effective, psychometrically sound, treatment-relevant method of assessment that reflects the state of the art. The authors provide the interdisciplinary professional community with proven, practical, and useful assessment strategies for these too commonly encountered problems. Child clinical and school psychologists, child psychiatrists and exceptional educators, social workers, and pediatricians--all professionals who provide services to children and adolescents suffering form these disorders.
