Family Chaos, Interparental Conflict, and Preschooler Adjustment: Comparing Mediation and Moderation Models

Children residing in chaotic homes exhibit greater behavior and adjustment problems. Proximal factors, such as interparental conflict, may play a role, although the ways in which these factors interplay in predicting adjustment problems is unclear. We explored different models for how chaos and conflict work together to predict child adjustment. We hypothesized that chaos would both moderate and mediate the relationship between interparental conflict and preschooler adjustment and that there would be a stronger pattern of associations for fathers than mothers. A community sample of 70 families with preschoolers participated in the current study. Parents engaged in a conflict resolution task during which their child was present. Interparental conflict was coded assessing for specific positive and negative conflict expressions, intensity of emotional expressions, and degree of resolution. Conflict codes were sorted into three categories: positive, angry, and depressive conflict. Parents completed the Strengths and Difficulties Questionnaire (SDQ) assessing child adjustment and the Confusion, Hubbub, and Order Scale (CHAOS) assessing levels of chaos and disruption in the home. Path analyses revealed evidence for mediation in the father: fathers’ angry conflict was significantly predictive of greater chaos, which was in turn predictive of greater child peer problems. No evidence of mediation was found for mothers. Chaos also moderated associations between conflict and child adjustment for both mothers and fathers, such that dimensions of conflict were significantly associated with child adjustment in high chaos, but not low chaos homes. Clinical implications are discussed.
