In addressing cited research gaps, this study investigated associations among polyvictimization, dissociation, numbing, callous-unemotional (CU) traits, and borderline personality (BP) traits in relation to offending in a sample of 782 youth (579 boys and 203 girls) recruited from a detention center.

The increasing prevalence of girls in the juvenile justice system suggests the importance of examining whether models of adolescent offending are differentiated by gender. Polyvictimization has emerged as a robust predictor of youth justice involvement, especially for girls, and research exploring mechanisms underlying the link between polyvictimization and offending suggests further gender differences, in that callous-unemotional (CU) traits have been implicated in samples of boys; whereas, borderline personality (BP) traits have been implicated amongst girls; however, a limitation of these studies is that most have included all-male or all-female samples, thus not allowing for comparisons across gender. Further, few studies have used a trauma-informed lens to investigate posttraumatic symptoms, particularly dissociation and emotional numbing, that might account for these associations. The current study found that for both genders, polyvictimization was related to BP through the indirect effect of dissociation and to CU through the indirect effect of emotional numbing, which was hypothesized. Further, for both genders, path models indicated indirect effects on the association between polyvictimization and offending through dissociation and BP. These results suggest the value of using a trauma-informed approach to understanding youth justice involvement and continuing to fine-tune models of gender differences in traumatized girls' and boys' offending.
