In the style of a handbook, this volume conveys the current state of knowledge on the topic of behavioral disorders in young people. It refers to children and adolescents whose behavior deviates in undesirable ways from societal expectations, meaning young individuals who exhibit signs of neglect, psychosocial disorders, delinquent behavior, and/or severe anxiety, depression, and suicidal tendencies. The authors present effective educational concepts and measures in a clear format; they describe and evaluate diagnostic procedures, highlight proven and effective intervention methods, and engage with the work and function of relevant institutions. The book serves as both a comprehensive introduction for students and a current guide for professionals.
