The Indirect Effects of Adolescent Psychopathic Traits on Aggression Through Social-Cognitive Factors

Psychopathic traits have been shown to designate youth who are at-risk for varied forms of aggression. The present study examined the indirect effects of social-cognitive factors (i.e., hostility and general approval of aggression) in the association between psychopathic traits (i.e., callous-unemotional traits, narcissism) and two functions of adolescent aggression (i.e., reactive, proactive). Participants were 209 (178 males, 31 females) adolescents aged 16 to 19 attending a residential program for youth who have dropped out of high school. Using a cross-sectional design, participants completed self-report measures of callous-unemotional traits (i.e., callousness, uncaring, unemotional), narcissism, aggression, hostility, and approval of aggression. Results indicated significant indirect effects of callousness on both functions of aggression through hostility. Similarly, there were significant indirect effects of narcissism on both functions of aggression through hostility. Significant indirect effects were also evident for general approval of aggression in the relations between callous-unemotional traits (both callous and uncaring dimensions) and both functions of aggression, and between narcissism and both functions of aggression. These results suggest the importance of examining social-cognitive processes insofar as they may contribute to the relation between psychopathic traits and aggression in youth and serve as possible targets of intervention.
