There is theoretical and empirical support suggesting exposure to interparental conflict has important implications for child adjustment; however, it is unclear the role other factors may play in mediating or moderating that relationship. Multiple theories hypothesize developmental differences in children's reactions to interparental conflict, but few studies have investigated these differences within a prospective longitudinal design. The purpose of the proposed study is to examine in detail the impact that the timing and chronicity of exposure to interparental conflict has on children's later adjustment difficulties. The effect of these factors will be investigated prospectively in a community sample of more than 6,000 families with varying degrees of interparental conflict and adjustment difficulties. We made three main hypotheses. First, we hypothesize that interparental conflict will positively predict subsequent child adjustment. Second, based on theoretical and empirical support, we hypothesize that children exposed to parent conflict earlier in their development will have worse emotional and behavioral outcomes when compared to children exposed to conflict at later age points. Finally, we predict that children exposed to chronic elevated levels of interparental conflict over the early and middle years of their development will show increased levels of subsequent adjustment problems. In addition, children's gender, nonverbal receptive skill, and locus of control will be examined as potential moderators of the parent conflict-child adjustment association. The results of this study may serve as a step toward a better understanding of how timing and chronicity of exposure to parent conflict impact the relationship between parent conflict and children's adjustment problems.
