This book describes methods and strategies for assessing a comprehensive array of childhood disorders, child health risks, and adolescent problems. It highlights the ongoing interplay among behaviors, cognition, and affects as they unfold within the young person's social network. Each chapter presents a conceptual framework for understanding the problem at hand, discusses assessment procedures that can be used to inform clinical interventions, and reviews the available empirical data. A major emphasis is placed on the family and the broader social environment, both as a context for understanding the child's strengths and weaknesses and as a focus for assessment and intervention.
