The present study examined the moderating role of maternal and paternal behaviors on the association between ADHD symptoms and antisocial behavior. The data are from a Swedish community-based study with 2886 adolescent participants, aged 13-15. We analyzed the adolescents' self-reports of negative and positive parental behavior, ADHD symptoms, and antisocial behavior. Results show that ADHD symptoms significantly predicted levels of antisocial behavior in both maternal- and paternal-moderated regression models. Also, several significant interaction effects emerged. Fathers' attempted understanding and mothers' warmth significantly buffered the association with antisocial behavior. In turn, mothers' negative behaviors-both coldness and rejection and angry outbursts-significantly enhanced the association with antisocial behavior, whereas only fathers' angry outbursts emerged as a significant moderator. Thus, there is support for differential effects of maternal and paternal behavior on the association between ADHD symptoms and adolescent antisocial behavior.
