The aim of the study was to evaluate the contribution of self-esteem and locus of control in generating in the youth an aggressive coping strategy in a social conflict situation. The study made use of a proprietary questionnaire to study the coping strategy of youth in a social conflict situation (KSMK), the Rosenberg Self-Esteem Scale (SES), and the questionnaire to Study the Locus of Control (KBPK) created by G. Krasowicz and A. Kurzyp-Wojnarska. Empirical studies were carried out in junior high schools [Polish: gimnazjum] in Wroclaw and the surrounding area. They involved 811 adolescents (414 girls and 397 boys) aged 13 – 15. In the light of the performed studies it was stated that low general selfesteem in youth and strong belief in the influence of others on positive or negative effects of events play a particular role in the choice of aggressive strategy of young people to cope in a social confl ictsituation.
