This volume richly illustrates the contributions of psychology and behavioral science to the prevention of mental and health problems across the life span. Each chapter, authored by distinguished researchers, summarizes the existing empirical literature on preventive interventions, presents the latest findings in the field, describes a case example, and offers suggestions for future directions. Topical coverage includes aging, chronic health problems, marital disorder, delinquency and antisocial behavior, racism and sexism, community disintegration, and more. For those on the front lines, including program developers and evaluators, human service administrators, and community organizers, educators, and advocates to scholars and students of preventive science, this book will stimulate new dialogues about how to invent preventive solutions.
