In this volume, Romance and Sex in Adolescence and Emerging Adulthood: Risks and Opportunities, top scholars in the field of family research examine the nature and origin of adolescents’ contemporary patterns of sexual and romantic relationships, spanning such diverse topics as the evolutionary roots of these behaviors, as well as policies and programs that represent best practices for addressing these issues in schools and communities. The text offers interdisciplinary expertise from scholars of psychology, social work, sociology, demography, economics, human development and family studies, and public policy.Adolescents and young adults today face very different choices about family formation than did their parents’ generation, given such societal changes as the rise in cohabitation, the increase in divorce rates, and families having fewer children. These demographic trends are linked in important ways and provide a backdrop against which adolescents and emerging adults form and maintain romantic and sexual relationships. Editors Crouter and Booth address such questions as:*What are the ways in which early family and peer relationships give rise to romantic relationships in the late adolescent and early adult years?*How do early romantic and sexual relationships influence individuals’ subsequent development and life choices, including family formation?*To what extent are current trends in romantic and sexual relationships in adolescence and emerging adulthood problematic for individuals, families, and communities, and what are the most effective ways to address these issues at the level of practice, program, and policy?Romance and Sex in Adolescence and Emerging Adulthood: Risks and Opportunities is an enlightening compilation of essays for academicians and upper-lever undergraduate and graduate students in the fields of human development and family studies, sociology, and psychology, as well as for practitioners in those fields who work with families and adolescents. The chapters are accessible to a wide variety of audiences.
