Behavioral disorders characterized by aggressive behavior, as well as fears, depression, or disturbed attachment behavior, are very challenging for parents, educators, and those affected. The authors have many years of experience in researching and treating behavioral disorders. In the first part of the book, they present the latest findings on the development and maintenance of these disorders. Results from a longitudinal study, along with numerous case studies and interviews with teachers and adolescents, provide a first glimpse into the experiences of those affected. The second part of the book describes approaches to diagnosis and therapy, emphasizing that support can and must come from various directions: What can parents and educators do? What options do psychology and psychotherapy offer? This book is not only based on current knowledge but is also very illustrative.
