This vital guide takes a new approach to conduct and oppositional defiant disorders (CD and ODD), presenting the science in an accessible way to empower both parents and practitioners. Vanzin and Mauri cover a range of key topics, including distinguishing between typical and atypical behavioral development, how to choose the best course of treatment for a child and how parental behavior can help or hinder progress, providing a comprehensive overview of these two disorders. In six clearly labeled chapters, the authors explain the science behind popular treatments, providing practical advice and clear, step-by-step instructions on how to approach challenging behavior. Written in concise and straightforward language, each chapter concludes with “important points” summarizing key information, designed to help those living or working with children suffering from behavioral disorders to both understand the nature of the disorders and achieve the best outcome for the child. The final chapter of the book presents an in-depth case study of a child with behavioral disorders, thoroughly detailing symptoms, treatment and outcome, providing a demonstration of best practice and affirming that challenging behavior can be effectively managed. Illustrated with clinical vignettes of the experiences of children living with CD and ODD, Understanding Conduct Disorder and Oppositional- Defiant Disorder is essential reading for parents and caregivers, as well as practitioners in clinical and educational psychology, counseling, mental health, nursing, child welfare, public healthcare and those in education.
