Despite a recent leveling off of the divorce rate, almost half of the children born in the last decade will experience the divorce of their parents, and most of these children will also experience the remarriage of their parents. Most children initially experience their parents' marital rearrangements as stressful; however, children's responses to their parents marital transitions are diverse. Whereas some exhibit remarkable resiliency and in the long term may actually be enhanced by coping with these transitions, others suffer sustained developmental delays or disruptions. Others appear to adapt well in the early stages of family reorganizations but show delayed effects that emerge at a later time, especially in adolescence. The long-term effects are related more to the child's developmental status, sex, and temperament; the qualities of the home and parenting environments; and to the resources and support systems available to the parents and child than they are to divorce or remarriage per se. In recent years, researchers have begun to move away from the view that single-parent and remarried families are atypical or pathogenic families and are focusing on the diversity of children's responses and to the factors that facilitate or disrupt the development and adjustment of children experiencing their parents' marital transitions.
