Adolescents embody the best hopes of American society. Their vital role in shaping our future lends particular significance to their success in negotiating the passage from childhood to adulthood, while their intensity and visibility often make them barometers of social change. It is all the more remarkable, then, that this critical period has only recently captured the full attention of researchers.

At the Threshold presents the long-awaited findings of the Carnegie Foundation study on adolescence. It offers a comprehensive overview of what investigators are learning about normal development and provides an interdisciplinary synthesis of research into the biological, social, and psychological changes occurring during this key stage in the life span. While focusing on the contexts of adolescent life—social and ethnic, family and school, leisure and work—it also addresses how researchers are doing in the effort to understand the intersection of processes that initiate and sustain adolescent development and to characterize the extraordinary changes that occur during these years.

Contrary to popular belief, large numbers of young people continue to mature into productive members of society. At the Threshold seeks to allow professionals and nonprofessionals alike important access to the reality of normal adolescent experience. The authors recognize that only if we begin to understand and clearly articulate the parameters of successful adolescent development can we hope to intervene with those individuals whose lives seem aimed toward unsatisfactory futures.

Changing Youth in a Changing Society begins with a complete survey of the problems of youth, showing which disorders peak during the teenage years. With this background of fact firmly established, Michael Rutter turns to the difficult historical questions about whether adolescent disorders are truly becoming more frequent. Here Rutter shows that the news is not uniformly bad. Some psychosocial problems, such as teenage alcoholism and crime, are still on the rise. But other problems, among them the much heralded generation gap, turn out to be largely mythical. Still others, like the decline in educational achievement, may only reflect historical changes in the population of teenagers being assessed.

Rutter’s historical analysis supports a comprehensive discussion of the causes of adolescent disorder. The effects of heredity, childhood, family, school, peer group, religion, the media, and the urban environment are all assessed in review of research which is a model of clarity and good sense. This review provides the factual framework for informed recommendations for more effective prevention and treatment of adolescent disorders.

On the way to womanhood, what does a girl give up? For five years, Lyn Mikel Brown and Carol Gilligan, asking this question, listened to one hundred girls who were negotiating the rough terrain of adolescence. This book invites us to listen, too, and to hear in these girls' voices what is rarely spoken, often ignored, and generally misunderstood: how the passage out of girlhood is a journey into silence, disconnection, and dissembling, a troubled crossing that our culture has plotted with dead ends and detours.

In the course of their research, Brown and Gilligan developed a Listener's Guide - a method of following the pathways of girls' thoughts and feelings, of distinguishing what girls are saying by the way they say it. We witness the struggle girls undergo as they enter adolescence only to find that what they feel and think and know can no longer be said directly. We see them at a cultural impasse, and listen as they make the painful, necessary adjustments, outspokenness giving way to circumspection, self-knowledge to uncertainty, authority to compliance. These changes mark the edge of adolescence as a watershed in women's psychological development, a time of wrenching disjunctions between body and psyche, voice and desire, self and relationship. Brown and Gilligan open their method to us and share their discoveries as they encourage girls at different ages to speak about themselves in conversation with women. They follow some of these girls over time, listening to changes in their distinct voices from one year to the next, addressing their successes and failures as they confront one barrier after another.

This groundbreaking work offers major new insights into girls' development and women's psychology. But perhaps more importantly, it provides women with the means of meeting girls at the critical crossroads of adolescence, of harkening to the voices of girlhood and sustaining their sell-affirming notes.

Seventy deeply troubled teenagers spend weeks, months, even years on a locked psychiatric ward. They’re not just failing in school, not just using drugs. They are out of control—violent or suicidal, in trouble with the law, unpredictable, and dangerous. Their futures are at risk.

Twenty years later, most of them still struggle. But astonishingly, a handful are thriving. They’re off drugs and on the right side of the law. They’ve finished school and hold jobs that matter to them. They have close friends and are responsible, loving parents.

What happened? How did some kids stumble out of the woods while others remain lost? Could their strikingly different futures have been predicted back during their teenage struggles? The kids provide the answers in a series of interviews that began during their hospitalizations and ended years later. Even in the early days, the resilient kids had a grasp of how they contributed to their own troubles. They tried to make sense of their experience and they groped toward an understanding of other people’s inner lives.

In their own impatient voices, Out of the Woods portrays edgy teenagers developing into thoughtful, responsible adults. Listening in on interviews through the years, narratives that are often poignant, sometimes dramatic, frequently funny, we hear the kids growing into more composed—yet always recognizable—versions of their tough and feisty selves.

The Relationship Code is the report of a longitudinal study, conducted over a ten-year period, of the influence of family relationships and genetic factors on competence and psychopathology in adolescent development. The sample for this landmark study included 720 pairs of same-sex adolescent siblings—including twins, half siblings, and genetically unrelated siblings—and their parents.

Using a clear expressive style, David Reiss and his coinvestigators identify specific mechanisms that link genetic factors and the social environment in psychological development. They propose a striking hypothesis: family relationships are crucial to the expression of genetic influences on a broad array of complex behaviors in adolescents. Moreover, this role of family relationships may be very specific: some genetic factors are linked to mother–child relationships, others to father–child relations, some to relationship warmth, while others are linked to relationship conflict or control. The specificity of these links suggests that family relationships may constitute a code for translating genetic influences into the ontogeny of behaviors, a code every bit as important for behavior as DNA-RNA.
