Much research has demonstrated that marital discord and divorce are risk factors for the development of childhood behavioural and emotional disorders. Although theoretical models and research programs that focus attention on possible mechanisms of influence are scarce, it is clear that marital discord can powerfully influence children via its effect on spouse's parenting behaviour. Thus, marital discord can represent a significant impediment for intervention programs that aim to help children by providing parent training. It is argued that marital and child focused interventions can be successfully integrated in behavioural family therapy. A description of the process and content elements of such an integration is presented, and future directions for research and practice are discussed.
