In this book, Scales and Leffert review more than 800 scientific articles and reports that relate to Search Institute's conceptual framework of developmental assets—positive relationships, opportunities, skills, values, and self-perceptions that all young people need to be healthy, caring, and productive. Each chapter shows (1) how the scientific literature defines the category of assets; (2) research findings on the impact assets on young people's behaviors, including variations in findings among different populations of youth; (3) in-depth information on how each asset works; (4) data on young people's experiences from Search Institute surveys of almost 100,000 6th–12th grade youth; (5) areas in the scientific literature that may not be adequately reflected in the current framework of developmental assets; and (6) what the literature says about how the assets can be built in young people's lives.
