This review summarizes research and theory on the impact of interparental conflict for child well-being. Drawing from this literature the primary focus of many family programs on parenting seems unconvincing. Contemporary approaches increasingly acknowledge the importance of addressing the interparental relationship to reduce and/or prevent behavior problems in children. However, studies examining the impact of enhancing the parents’ relationship for children are still in their infancy. Yet, this emerging line of research indicates that couple-focused interventions alone or adjunct to parenting programs may be a potent means of increasing child adjustment. The potential of couple-focused interventions to support children’s adjustment and practical implications of such approaches are discussed. Future directions are suggested that urgently need to be addressed to advance this promising area of family psychology.
