The development of cognitive empathy relies heavily on the theory of mind — the...

Area of Science:

  • Psychology
  • Developmental Psychology
  • Trauma Studies

Background:

  • Posttraumatic stress significantly impacts adolescent behavior and social interactions.
  • Understanding trauma's influence on aggression is crucial for effective intervention.

Purpose of the Study:

  • To investigate how posttraumatic stress affects adolescent responses to peer provocation.
  • To examine gender-specific differences in reactions to peer conflict among adolescents with trauma symptoms.

Main Methods:

  • A large sample of 2678 adolescents (13-17 years) from Northern Russia completed self-report measures.
  • Participants rated hypothetical peer provocation scenarios assessing response choices and intentionality attribution.
  • Analysis compared adolescents with and without clinically significant posttraumatic stress symptoms.

Main Results:

  • Adolescents with high posttraumatic stress symptoms were less likely to discuss conflicts and more prone to physical aggression.
  • Gender differences emerged: girls with high trauma symptoms endorsed hostile intentions and avoided verbal aggression more than boys.
  • Girls with high trauma symptoms showed increased physical aggression and avoidance of social aggression, unlike boys.

Conclusions:

  • Elevated posttraumatic stress symptoms are linked to increased aggressive responses in peer conflicts.
  • Reaction patterns to provocation are gender-specific, underscoring the need for tailored approaches.
  • Evaluating posttraumatic stress history is essential for adolescents exhibiting aggressive behaviors.
