The editors of this volume explore the various caregiving arrangements and dimensions that the term coparenting comprises. Part I examines the concepts, theories, and empirical research underlying this dynamic socialization force that is characteristic of all family systems. Part II explores clinical applications -- the various assessments and interventions that promote coparenting. The volume concludes with policy implications and a model paradigm that encourages good coparenting as a powerful support for all children's social, emotional, and behavioral needs.
