This study investigated early parent- child relationships and how children\u27s use of relational and physical aggression varies with aspects of those relationships during the preschool years. Specifically, parenting styles, parents\u27 use of psychological control, and parents\u27 report of their children\u27s reunion behaviors were assessed. Analyses revealed significant associations between children\u27s use of both relational and physical aggression and parents\u27 reports of their own and their partner\u27s parenting style, psychological control behaviors, and indicators of the attachment relationship. The results highlight the importance of investigating both mothers\u27 and fathers\u27 parenting and the sex of the child in studies of potential links between parenting behaviors and young children’s relational and physical aggression. Findings were considered in the context of each perspective and suggestions for future research and implications for intervention and prevention are discussed
