Preventing Youth Problems provides information needed to prevent five of the most common, costly, and dangerous problems of adolescence: anti-social behavior, tobacco use, alcohol and drug abuse, and sexual behavior that risks disease and unwanted pregnancy. Over the past thirty years, scientific research on children and adolescents identified the major conditions influencing each of these problems.
Each of the chapters in this volume provides a concise summary of what is known about one of these five problem behaviors. Each chapter covers the following essential points:

- Incidence, prevalence, and cost of the problem, vital for gauging the importance of preventing the problem and for making the case for such efforts in public discussion of priorities;
- Biological and environmental influences which increase or decrease the likelihood of these problems; and,
- Principles, programs and policies that have been shown to reduce the incidence of each problem, information that can help in prevention of these behaviors.

What do evolutionary science and contextual behavioral science have in common? Edited by David Sloan Wilson and Steven C. Hayes, this groundbreaking book offers a glimpse into the histories of these two schools of thought, and provides a sound rationale for their reintegration. Evolutionary science (ES) provides a unifying theoretical framework for the biological sciences, and is increasingly being applied to the human-related sciences. Meanwhile, contextual behavioral science (CBS) seeks to understand the history and function of human behavior in the context of everyday life where behaviors occur, and to influence behavior in a practical sense. This volume seeks to integrate these two bodies of knowledge that have developed largely independently. In Evolution and Contextual Behavioral Science, two renowned experts in their fields argue why ES and CBS are intrinsically linked, as well as why their reintegration-or, reunification-is essential. The main purpose of this book is to continue to move CBS under the umbrella of ES, and to help evolutionary scientists understand how working alongside contextual behavioral scientists can foster both the development of ES principles and their application to practical situations. Rather than the sequential relationship that is typically imagined between these two schools of thought, this volume envisions a parallel relationship between ES and CBS, where science can best influence positive change in the real world.

This book provides information needed to prevent five of the most common, costly, and dangerous problems of adolescence: anti-social behavior, tobacco use, alcohol and drug abuse, and sexual behavior that risks disease and unwanted pregnancy. It is an important resource for psychologists, sociologists, social workers, and educators, as well as for upper-level students in these areas.

What if there were a way to prevent criminal behavior, mental illness, drug abuse, poverty, and violence? Written by behavioral scientist Tony Biglan, and based on his ongoing research at the Oregon Research Institute, The Nurture Effect offers evidence-based interventions that can prevent many of the psychological and behavioral problems that plague our society. For decades, behavioral scientists have investigated the role our environment plays in shaping who we are, and their research shows that we now have the power within our own hands to reduce violence, improve cognitive development in our children, increase levels of education and income, and even prevent future criminal behaviors. By cultivating a positive environment in all aspects of society-from the home, to the classroom, and beyond-we can ensure that young people arrive at adulthood with the skills, interests, assets, and habits needed to live healthy, happy, and productive lives. The Nurture Effect details over 40 years of research in the behavioral sciences, as well as the author's own research. Biglan illustrates how his findings lay the framework for a model of societal change that has the potential to reverberate through all environments within society.

Clinicians and researchers have long recognized that adolescent delinquency, substance use, smoking, and risky sexual behavior tend to co-occur. Until now, however, the field has lacked a thoughtful examination of why this pattern exists and the implications for research, policy, and practice. Filling a crucial gap, this volume provides a comprehensive analysis of current knowledge on the multiproblem phenomenon. Leading interdisciplinary experts draw on clinical and public health perspectives to shed new light on the causes and consequences of adolescent behavior problems/m-/and to examine "what works" in prevention and treatment. Mapping out important future directions for the field, this is a state-of-the-science sourcebook and text for anyone working with or studying adolescents at risk. The volume first reviews the epidemiology of serious youth problems and documents their costs to individuals, families, and communities. A lifespan developmental perspective is brought to bear on understanding risk and protective factors for problem behavior, with consideration of biological, family, school, peer, and community influences.; Building on these foundations, subsequent chapters pres
