Aggression as a factor of emergence of delinquent behaviour (gender aspect)

155 male and 110 female adolescents with substance abuse who serve their sentence at juvenile correctional facility were examined. It was revealed that male adolescents were convicted for crimes against life in 34,6 % of cases, but female adolescents - only in 25,5 %. Male adolescents are involved in substance use earlier than female adolescents. Level of aggression revealed with use of verbal and non-verbal methods in female adolescents is higher than in male adolescents. It was revealed that hostile and aggressive reactions in adolescents contribute to their involvement in narcotization. At the same time, male adolescents demonstrated major reserve of role variants, high potential of adjustability, and active use of communication for selfassertion and achievement of their aims, low level of attachment and formalization of interpersonal contacts. Carried out study allowed reveling the gender traits of juvenile offenders which influence on structure of aggressive behavior and allow widening the understanding of mechanisms of aggressive behavior. Revealed traits should be taken into account during conducting the educational and rehabilitative work with these categories of convicts.
