Parental response, physical coercion and warmth and their relationships with childhood aggression were assessed with 277 children (142 boys; M age = 56.5 months, SD = 10.93 months) in Hong Kong. Results indicated that both fathers and mothers reported significantly more intervention strategies in response to hypothetical vignettes of physical aggression than relational aggression. Both fathers' and mothers' self-reported physical coercion was positively correlated with boys' and girls' composite scores of physical and relational aggression as reported by teachers, fathers and mothers, whereas fathers' self-reported warmth was associated with a lower level of physical and relational aggression in boys. Furthermore, maternal warmth moderated the association between physical coercion and girls' relational aggression. Findings suggest that parents' normative beliefs regarding relational aggression should be challenged and the general acceptability of parental control in the Chinese context does not necessarily imply the absence of a link with childhood aggression.
