This revised and expanded third edition text utilizes a public health framework and the latest epidemiological, treatment, and service systems research to promote a comprehensive understanding of the organization, financing, and delivery of mental health and substance abuse services in the United States. Written by national experts in the field, this timely work will provide policymakers, administrators, clinicians, and public health and behavioral health graduate students with the knowledge base needed to manage and transform mental health service systems, both nationally and locally.The book is unique in providing a public health framework of the most significant issues facing mental health policy makers, administrators, planners, and practitioners. It combines issues (e.g., evaluation; law; ethnicity) that extend across different age groups, treatment settings, and disorders, with issues that are population and disorder specific. The publication of this book is timely for those involved with the debate over national health care reform legislation, and provides important and timely information (on populations at-risk for mental disorders, services, and systems issues) for those responsible for implementing policies and programs resulting from this reform effort.
