Family system and individual child correlates of sibling behavior.

Abstract
In this study of the connections between marital adjustment and sibling behavior, the best predictor of younger siblings' prosocial behavior was found to be low interparental conflict. Older siblings' prosocial behavior was most associated with the mothers' marital adjustment. Younger siblings' agonistic behavior was related to marital adjustment and to the older children's activity level.
