[Predisposition for violence in adolescence].

Uncontrolled aggressiveness, violence, and reckless behavior make up the contents of many myths of the 'real man'. For youths with unfavourable developmental conditions these myths are especially important. Two types of adolescents, willing use violence, with antisocial personality developments are illuminated with the help of psychoanalytic models of understanding; the borderline disorder on a low structure level and the mimicry development with its 'false' structure development, which often leads to a wrong diagnosis. With specific interactions with youths of both types in an inpatient setting, developmental processes are described which then often lead to the use of violence if effective interventions are not used enough. In closing pedagogic, social-therapeutic and psychotherapeutic strategies for dealing with such adolescents are discussed.
