Interpersonal threat reactivity differentiates reactive and proactive aggression.

OBJECTIVE

Adolescents with Conduct Disorder (CD) display persistent patterns of antisocial and aggressive behavior, yet the mechanisms underlying different forms of aggression remain unclear. Prior research has linked antisocial behavior to atypical autonomic nervous system functioning, but few studies have examined physiological and subjective reactions to interpersonal conflict simultaneously.

METHOD: Participants were 234 adolescents (Mage = 15.68; 67% male) with CD. This study examined sympathetic nervous system reactivity using skin conductance responses (SCR) and self-reported emotional responses (e.g., arousal, dominance, and valence) to interpersonal threat in an immersive virtual reality paradigm.

RESULTS

Higher SCR threat reactivity was associated with reactive aggression. Greater self-reported feelings of dominance during interpersonal threat was associated with proactive aggression.

CONCLUSION

These results suggest that reactive aggression is associated with heightened physiological threat reactivity, whereas proactive aggression is associated with greater perceived control during interpersonal threat. This study points to distinct affective and physiological processes for reactive and proactive aggression in adolescents with CD. Furthermore, immersive VR paradigms are promising tools for understanding risk profiles for aggression in high-risk adolescents.
