Callous-Unemotional Traits and Executive Functions are Unique Correlates of Disruptive Behavior in Children.

This study examined the influence of executive functions on the association between callous-unemotional traits and severity and type of childhood disruptive behavior. Eighty one children aged 8-12 years and their parents participated in the study. We assessed children's callous-unemotional traits, executive functions, and two indices of disruptive behavior. Callous-unemotional traits and parent ratings of executive dysfunction were uniquely correlated with elevated conduct problems and oppositional and defiant behavior. Neither performance-based measures, nor parent ratings of executive function, moderated the association between callous-unemotional traits and disruptive behavior. Study findings suggest that executive functions and callous-unemotional traits may impact children's behavior independently.
