Objectives: This study aimed to examine the relation between early traumatic events, callous-unemotional traits and insecure attachment style with aggression in a sample of adolescent out-patient.

The obtained data were analyzed using Pearson correlation coefficient and multivariate regression analysis. Results: Regression analysis revealed that 13% variance of aggression can be predicted by early traumatic events, insecure style of attachment and callous-unemotional traits.
