This study sought to explore whether PTSD symptoms in detained adolescents were differentially related to high and low patterns of emotional reactivity, as determined based on callous-unemotional (CU) traits and emotion dysregulation. Analyses revealed four distinct groups based on these criteria: a low/no trauma control group with few PTSD symptoms, and three groups whose PTSD symptoms were distinguished by symptoms of emotional numbing. The study sought to determine whether these profiles were related to distinct patterns of aggression and delinquency. Results revealed that the low/no PTSD symptom group exhibited the least aggression and delinquency. Further, results indicated that higher CU traits and violent offending are associated with a combined PTSD symptom profile. Results suggest a relationship between PTSD symptoms, delinquency, aggression, and CU traits. Findings provide support for the existence of a secondary variant of CU youth who are more emotionally dysregulated and prone to both arousal and emotional detachment.

The overrepresentation of racial and ethnic minorities in crime has been an issue of debate. Some evidence, however, has shown that racial differences in offending are largely accounted for by economic disadvantage. Using data from the National Longitudinal Study of Adolescent Health (n = 4,290), the relationship between race and delinquency was examined looking at social disorganization factors. It was hypothesized that there would be racial and ethnic differences in delinquency and that these differences would be accounted for by social disorganization factors, specifically collective efficacy and economic disadvantage. The results show that compared to White adolescents Hispanic adolescents have increased odds of nonviolent and violent delinquency, and Black adolescents have increased odds of violent delinquency. Contrary to expectations, social disorganization factors did not account for the racial and ethnic differences in delinquency. Unexpectedly, higher levels of collective efficacy actually increased the odds of violent delinquency.
