JARCHO, Auteur Article en page(s) : p.1346-1358 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Violence exacts staggering personal and financial costs - a burden disproportionally born by adolescents and young adults. This may be partially due to an increased sensitivity to social rejection during this critical phase of development. Irritability, a transdiagnostic symptom, is often elicited by social interactions. Yet, little is known about age differences in social rejection-elicited aggression and irritability. Progress toward testing such relations has been hindered by a lack of ecologically-valid tasks that enable the measurement of in-the-moment social rejection-elicited aggression. Methods In this paper, we describe an initial study of young adults (n=55) that demonstrates the efficacy of a novel Virtual School and Aggression Paradigm (VS-AP). Next, we replicate these results in a second study of adolescents and young adults (ages 11-25?years; n=173) and examine relations between social rejection-elicited aggression, irritability, and age. Results We found that aggressive behavior in the VS-AP differed for accepting, rejecting, and unpredictable peer types (Study 1: F(2, 108)=20.57, p<.001, ?2=.28; Study 2: F(2, 344)=152.13, p<.001, ?2=.47), demonstrating that the VS-AP successfully models social rejection-elicited aggression. In Study 2, age was negatively correlated with aggressive behavior (r=?.29, p<.001) and irritability (r=?.28, p<.001), while irritability was positively correlated with aggressive behavior (r=.28, p<.001). Age moderated the relation between social rejection-elicited aggression and irritability. Specifically, irritability was more predictive of aggression in young adults than in adolescents (F(3, 167)=7.07, p<.001). Conclusions Data suggest mechanisms promoting rejection-elicited aggression may differ across development and vary for those with and without high levels of irritability. The VS-AP is a promising tool for probing neurocognitive, developmental, and clinically relevant mechanisms underlying social rejection-elicited aggression.
