This groundbreaking volume synthesizes the results of the Virginia Adult Twin Study of Psychiatric and Substance Use Disorders, which yielded longitudinal data on more than 9,000 individuals. The authors trace how risk for depression, anxiety, eating disorders, antisocial behavior, alcoholism, and substance abuse emerges from the interplay of a variety of genetic and environmental influences. Major questions addressed include whether risk is disorder-specific, how to distinguish between correlational and causal genetic and evironmental factors, sex differences in risk, and how risk and protective factors interact over time. The book also summarizes the conceptual underpinnings of the study and describes key methodological challenges and innovations.

'In the past decade there has been an explosion of research into the psychology of well-being. While we know that psychological well-being is partly heritable, it is only recently that researchers have started to investigate the specific genetic factors that influence well-being. Such research explores not only heritability, based on traditional twin study designs, but also includes studies combining some of the most recent molecular genetic techniques and methods. This landmark book summarizes the state of knowledge regarding heritability and molecular genetics in positive psychology. Divided into four parts, it starts by exploring the basics of genetics and associated research methodology, providing the reader with the knowledge required to understand the empirical work presented throughout the volume. The second part of the book focuses on heritability estimates of the most important positive psychology concepts based on quantitative behavioural genetics studies. In the third section of the book, results from more recent molecular genetics studies are presented including candidate gene, gene-environment interaction, as well as genome-wide association studies. This section also contains chapters on epigenetics and imaging genetics, both relatively new methodologies that are just about to make their way into the field of positive psychology. The fourth and final part of the book discusses more overarching questions regarding the roles of genes and environment in the development of well-being as well as a review and discussion of the current state of knowledge and future direction in this new field of inquiry. The first book of its kind, The Genetics of Psychological well-being is a major contribution to the positive psychology literature, and important for all those in the fields of positive psychology, psychiatric genetics, and well-being.

This book focuses on what makes people happy. The author explains methods for measuring subjective life satisfaction and well-being by discussing economic and sociodemographic factors, as well as the psychological, cultural and political dimensions of personal happiness. Does higher income increase happiness? Are people in rich countries, such as the United States, the United Kingdom and Scandinavian countries, happier than those living elsewhere? Does losing one’s job make one unhappy? What is the role of genetic endowments inherited from our parents? How important are physical and emotional health to subjective life satisfaction? Do older people tend to be happier, or younger people? Are close social relationships necessary for happiness? Do political conditions, such as respect for human rights, democracy and autonomy, play a part? How can governments contribute to the population’s happiness? This book answers these questions on the basis of extensive interdisciplinary research reflecting the current state of knowledge. The book will appeal to anyone interested in learning more about the various dimensions of personal well-being beyond the happiness-prosperity connection, as well as to policymakers looking for guidance on how to improve happiness in societies.

Childhood, adolescence, even the "twilight years" have been extensively researched and documented. But the vast terrain known as midlife—the longest segment of the life course—has remained uncharted. How physically and psychologically healthy are Americans at midlife? And why do some experience greater well-being than others? The MacArthur Foundation addressed these questions head-on by funding a landmark study known as "Midlife in the U.S.," or MIDUS. For the first time in a single study, researchers were able to integrate epidemiological, sociological, and psychological assessments, as well as innovative new measures to evaluate how work and family life influence each other. How Healthy Are We? presents the key findings from the survey in three sections: physical health, quality of life and psychological well-being, and the contexts (family, work) of the midlife. The topics covered by almost forty scholars in a wide variety of fields are vast, including everything from how health and well-being vary with socioeconomic standing, gender, race, or region of the country to how middle-aged people differ from younger or older adults in their emotional experience and quality of life. This health—the study measures not only health-the absence of illness—but also reports on the presence of wellness in middle-aged Americans. The culmination of a decade and a half of research by leading scholars, How Healthy Are We? will dramatically alter the way we think about health in middle age and the factors that influence it. Researchers, policymakers, and others concerned about the quality of midlife in contemporary America will welcome its insights. * Having a good life means having good relationships with others to almost 70% of those surveyed. Less than 40% mentioned their careers. * Reports of disruptive daily stressors vary by age, with young adults and those in midlife experiencing more than those in later adulthood. * Men have higher assessments of their physical and mental health than woman until the age of 60.

The understanding of how to reduce risk factors for mental disorders has expanded remarkably as a result of recent scientific advances. This study, mandated by Congress, reviews those advances in the context of current research and provides a targeted definition of prevention and a conceptual framework that emphasizes risk reduction. Highlighting opportunities for and barriers to interventions, the book draws on successful models for the prevention of cardiovascular disease, injuries, and smoking. In addition, it reviews the risk factors associated with Alzheimer's disease, schizophrenia, alcohol abuse and dependence, depressive disorders, and conduct disorders and evaluates current illustrative prevention programs. The models and examination provide a framework for the design, application, and evaluation of interventions intended to prevent mental disorders and the transfer of knowledge about prevention from research to clinical practice. The book presents a focused research agenda, with recommendations on how to develop effective intervention programs, create a cadre of prevention researchers, and improve coordination among federal agencies.

A comprehensive, up-to-date resource providing information about genetic influences on disorders of behavior.

How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.
