Abstract:
Little empirical work has explored the relation between destructive sibling conflict and conduct problems in children. This study used a measure of observed sibling conflict to examine its relations with maternal and teacher report of conduct problems in a low-income sample of 180 five-year-old boys and their close-age siblings. Early report of behavior problems and rejecting parenting were added to the analyses to control for these predictors and to examine interactive effects. The interaction between destructive sibling conflict and rejecting parenting predicted aggressive behavior problems across time and informants such that a rise in aggression scores was evident for children who had high levels of both sibling conflict and rejecting parenting. Sibling conflict was also directly related longitudinally to the Child Behavior Checklist Delinquency factor. Results are discussed in terms of additive risk models and G. R. Patterson's (1984, 1986) theory of coercion.
