The social development model (Catalano & Hawkins, 1996) was adapted to examine the unique influence of mothers and fathers on their children's antisocial behavior. Analyses examined 325 families with sixth-grade children. Structural equation modeling was used to assess unique influences of constructs specific to mothers or fathers. Multiple-group comparisons were conducted to identify differences in the relationships between constructs for daughters versus sons. Results suggested that, although the relationships were often similar for both parents and for both daughters and sons, mothers and fathers uniquely influenced their child's antisocial behavior depending on the child's gender. Overall, cross-gender influence appeared to be particularly important for father's control of their daughter's antisocial behavior. Implications for the prevention of antisocial behavior are discussed.
