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.
