Individuals with behavioral health disorders are significantly overrepresented in the criminal justice system. The incarceration of offenders with substance use disorders and mental illness has contributed to dramatic growth in the incarcerated population in the United States. Problem-solving courts provide judicially supervised treatment for behavioral health needs commonly found among offenders, including substance abuse and mental health, and they treat a variety of offender populations. By addressing the problems that underlie criminal behavior, problem-solving courts seek to decrease the “revolving door” that results when offender needs are not addressed. Problem-solving courts use a team approach among the judge, defense attorney, prosecutor, and treatment providers, which is a paradigm shift in how the justice system treats offenders with special needs. Offenders in problem-solving courts are held accountable for their behavior while being provided with judicially supervised treatment designed to reduce the risk of reoffending. Despite the proliferation of problem-solving courts, there are unanswered questions about how they function, how effective they are, and the most promising ways to implement problem-solving justice. Problem-Solving Courts and the Criminal Justice System is the first book to focus broadly on problem-solving courts. The changing landscape of the criminal justice system, recent development of problem-solving courts, and ongoing shift toward offender rehabilitation underscore the need for this book. This book provides those in the fields of mental health, criminal justice, law, and related fields with a comprehensive foundation of information related to the role of problem-solving courts in reforming the criminal justice system. This book also provides researchers, academics, administrators, and policy-makers with an overview of the existing research on problem-solving courts, including the challenges faced by researchers when examining these courts.
