Almost all shapes of adolescent risky and deviant behaviour take place in the context of peer-relations. The present study examined the role of parents and peer-relations with respect to two indicators of deviant political development. In the fall 1998, directly after the German parliamentary elections, 1309 East German adolescents were asked about their voting for a right-wing extremist party and their readiness to use violence in political action. Friend's voting was a strong predictor of individual voting for a right-wing extremist party, particularly when the friend was the best friend with a reciprocal nomination, and when the friends frequently communicated about political themes. In addition, voting behaviour and willingness to use violence were associated with membership in peer groups who met frequently. Finally, the violence-disposed adolescents spent more of their spare time with peers and less with their parents. Similarities of our results with the findings of research on deviant behaviour in non-political areas support the idea that deviant political behaviour could be an expression of a problematic life situation.
