With so many pressing problems confronting children and families in America, we must act now to begin to reduce the tragedy of needlessly wasted lives. --from the Preface by Rosalynn Carter Although mental disorders cost our nation $72.7 billion each year in treatment, related support, and lost productivity, the funding for prevention of mental disorders has been inconsistent, due in some part to a lack of confidence regarding the effectiveness of specific prevention programs. This book highlights some of the most effective prevention programs in the United States and offers readers a common set of principles to reduce maladaptive behavior in ourselves, our children, and society. Divided into five parts, the book begins with an overview of prevention history in this country and next shows ways to operationalize George W. Albee's incidence formula. Part 2 focuses on successful programs that increase parent-child interaction and parenting ability. Part 3 explores preschool programs, some of which use parents as teachers, others of which describe quality child care programming and programs that develop problem-solving abilities in early childhood. Part 4 examines school-age programs ranging from interventions in school settings to developing social competency and job readiness. And, Part 5 focuses on prevention interventions in adulthood, specifically unemployment and depression. With contributions form the leading researchers in the prevention field, this book provides readers with the best information available about effective prevention programs and the knowledge to develop these preventive services at both state and local community levels. Primary Prevention Works will be of interest to policymakers and to researchers and practitioners in developmental psychology, clinical psychology, family studies, social work, counseling, human services, nursing, and public health.
