Parenting is an Environmental Predictor of Callous-Unemotional Traits and Aggression: A Monozygotic Twin Differences Study

Callous-unemotional (CU) traits increase risk for children developing severe childhood aggression and Conduct Disorder. CU traits are typically described as highly heritable and debate continues about whether the parenting environment matters in their etiology. Strong genetically-informed designs are needed to test for the presence of environmental links between parenting practices and CU traits. Our objective was to determine whether parental harshness and parental warmth were related to children ’s aggression or CU traits when accounting for genetically-mediated effects.
