Neighborhood income and the expression of callous-unemotional traits.

Callous-unemotional (CU) traits, including an uncaring nature and reduced empathy, represent a strongly heritable pattern of socio-emotional responding linked with elevated risk for severe, persistent delinquent behavior. Although evidence suggests that CU traits vary continuously across the population, research linking CU traits and delinquency is often conducted with incarcerated or clinical samples, obscuring potential heterogeneity in this relationship across the full range of high-CU individuals. Using a nationally representative sample, this study examines the role of neighborhood income in moderating the association between CU traits and delinquency in terms of both level and type of offending. Findings corroborate the link between CU traits and delinquency and suggest that the link between high-CU traits and violent delinquency may be unique to youth living in low-income neighborhoods.
