Book excerpt: Emerging adulthood - the period between the late teens and mid-twenties - is a unique and important developmental period during which people gain relationship experience before settling on someone to partner with. Romantic Relationships in Emerging Adulthood presents a synthesis of cutting-edge research and theory on this topic. Leading scholars from demography, sociology, family studies, and psychology provide original data and theoretical analyses that address the formation, nature, and significance of romantic relationships in emerging adults. Until recently, it was assumed that romantic relationships in emerging adults were not particularly important or formative. The material presented allows this assumption to be thoroughly evaluated. This volume is intended to be a resource for anyone interested in understanding romantic relationships in emerging adulthood. It is especially appropriate for classroom use in upper-level undergraduate and graduate courses in the fields of family sociology, human development and family studies, clinical and developmental psychology, and social work.
