Parents play a central role in the lives of their children. Parent-child interaction is a central variable in the etiology of antisocial behaviour. Research suggests that families of antisocial individuals are characterized by harsh and inconsistent discipline, little positive parental involvement and poor monitoring and supervision. Thus parents could create environments for unhealthy parent-child relationships with subsequent antisocial behaviour of their adolescents. This book discusses several topics that may lead to antisocial behavior. It describes the etiology, genetic and environmental influences, as well as clinical management of antisocial behavior.
