The way that parents work together in their roles as parents, the coparenting relationship, has been linked to parental adjustment, parenting, and child outcomes. The coparenting relationship offers a potentially modifiable, circumscribed risk factor that could be targeted in family-focused prevention. This paper briefly outlines an integrated and comprehensive view of coparenting, and suggests that the time around the birth of the first child is an opportune moment for coparenting intervention. To support the development of such prevention programs, an outline of the possible goals of coparenting intervention is presented with a description of the processes by which enhanced coparenting may have effects in each area. The paper discusses several issues involved in developing and disseminating effective coparenting interventions.
