Risk Factors for Antisocial Behavior in Juveniles: A Multidisciplinary Perspective Abstract In order to understand the etiology of childhood and adolescent delinquency, researchers now recognize the need to identify risk factors for antisocial behavior across multiple disciplinary domains. Relative to psychological and social factors, biological factors have been the focus of little criminological research. This dissertation addresses this limitation by examining biological risk factors for antisocial behavior in children and adolescents. This dissertation consists of three papers that examine heart rate and hormones in relation to aggression and other antisocial behavior problems in youth. The first paper examines the relationship between reduced heart rate and antisocial behavior. Although low heart rate is a well-replicated biological correlate of antisocial behavior, the mechanism underlying this relationship remains largely unknown. This study addressed this limitation by examining possible mediators of the relationship between heart rate and antisocial behavior in a community sample of adolescent boys. This paper is the first ot show that impulsive sensation seeking underlies the relationship between aggression and heart rate.
