The purpose of the study was to find personality predictors of aggressive coping strategies in adolescents in situations of social conflict. The empirical studies have been conducted in junior high schools on a sample of 893 adolescents (468 girls and 425 boys) aged 13-15. The study employed the following instruments: the Stress Assessment Questionnaire (Kwestionariusz Oceny Stresu, KOS) designed by D. Wlodarczyk and K. Wrzesniewski, The Rosenberg Self-Esteem Scale (SES), the Spielberger Three-Factor Inventory of Personality States and Traits (TISCO), as well as the Questionnaire for Analysis of Coping Strategies in Adolescents in Situations of Social Conflict (KSMK) designed by D. Borecka-Biernat. The results of the studies indicate that the assessment of a situation of conflict as a threat increases the implementation of the aggressive coping strategy in young people in situations of social conflict. Participation of adolescents in a situation in which the realization of their goals is under threat increases negative emotions. Aggression is a form of coping with anger experienced in a situation of social conflict.
