This book provides a practical, solutions-focused approach to controlling and preventing juvenile delinquency and a systematic analysis of the juvenile delinquency problem in the United States. The case material furthers the students’ understanding of delinquency problems through the author’s analysis and the voices of youths who have found themselves adjudicated as delinquents. Also revealed is how the juvenile justice system has changed significantly over the past one hundred years, beginning with the modification of treating juveniles separately and differently from adult criminals at the beginning of the twentieth century. This book not only deals with the overall traditional juvenile justice court system and treatment approaches, but also presents stimulating data on the psychology of juvenile delinquency based on the author’s direct work with delinquents incarcerated in mental hospitals.
