The essays in this volume explore the psychological dimensions of lesbian, gay, and bisexual identities from puberty to adulthood. The essays focus upon three general areas: theoretical frameworks that are important in understanding the development of sexual orientation in adolescence,challenges faced by lesbian, gay, and bisexual (LGB) youth, and issues related to interventions and services for LGB youths in community settings. Changes in biological processes, relationships, and community interactions influence the emergence of sexuality in all young people. The process is morecomplex and difficult for LGB teenagers. Fortunately, the cultural changes that have allowed LGB youths to become more open about themselves at earlier ages have also allowed social and behavioral scientists the opportunity to study them. This volume presents authoritative, research-based reviews ofthis ever-increasing area of study and social concern.
