Despite the existence of effective and economical psychological interventions for many mental disorders, the adoption of these treatments in service provision settings worldwide has lagged. A major gap persists between the development and identification of such interventions and their availability to the general public. Building upon the multidisciplinary literature on the science of dissemination and implementation, Dissemination and Implementation of Evidence-Based Psychological Interventions examines state-of-the-art programs to improve access to psychological interventions. Renowned experts describe leading efforts to facilitate the transport of evidence-based treatments, alongside innovative strategies for achieving the goals presented. Analyzing dissemination and implementation programs that range in aims and scope and include both national and local efforts, this book is divided into two parts. Chapters in Part I provide discussion of the history of evidence-based psychological interventions and the need for dissemination and implementation, an overview of the science of dissemination and implementation, and a review of the effectiveness of methods for clinician training. Chapters in Part II describe leading dissemination and implementation programs internationally, including the procedures and practices utilized and data on outcomes. The book concludes with a chapter by the volume’s editors that proposes and discusses ten of the most important future directions for the science and practice of dissemination and implementation in mental health care. A crucial challenge in the field today is to translate the successes of treatment development research into the reduction of the public health burden of mental illness on individuals, families, and societies. This pioneering volume will be central to that effort and an essential resource for mental health practitioners and researchers, as well as decision-makers throughout the mental health care system.
