In recent years a dizzying array of programs has emerged to meet the needs of struggling teens and their families-wilderness therapy programs, therapeutic boarding schools, alternative schools, mentoring and court diversion programs, independent living programs, and myriad day treatment and partial hospitalization services. Yet not all of these offerings employ mental health professionals or follow evidence-based treatment protocols. Some programs are licensed and accredited, but many are not, and some use techniques that are highly controversial, even abusive, resulting in injury and accidental death. Frederic G. Reamer and Deborah H. Siegel have written the first scholarly book on this influential and controversial industry. They begin with a time line of Americans’ changing attitudes toward challenging teens and the programs and schools established to handle this population. Then they summarize reputable organizations, including a selection of community-based and residential programs and schools, and provide brief descriptions of typical services. The authors candidly discuss a number of troubling scandals and tragedies, exposing the tragic consequences of emotionally and physically abusive practices, and recommend a range of empirically sound interventions for the clinical challenges of adolescent depression, bipolar disorder, anxiety, oppositional behavior, eating disorders, and attention-deficit/hyperactivity disorder. The authors conclude with a blueprint for reform and twenty best practice principles relating to harm prevention, program-based discipline, industry regulation, quality assurance, parental involvement, staff education, and after-care services.
