Study Finds Widespread Brain Alterations in Kids with Callous Traits

Parenting Practices Influence Development of Antisocial Behaviors in Children

Emerging research suggests less parental warmth and more harshness in the home environment can affect aggressive trait development among children. The parenting behavior can influence whether a child develops empathy and a moral compass, a set of characteristics known as callous-unemotional (CU) traits.

University of Pennsylvania psychologist Dr. Rebecca Waller and her research team analyzed small differences in parenting among 227 identical twins. The investigators studied the parenting that each twin experienced to determine whether these differences predicted the likelihood of antisocial behaviors emerging.

They learned that the twin who experienced stricter or harsher treatment and less emotional warmth from parents had a greater chance of showing aggression and CU traits. Callous-unemotional traits include limited empathy, a lack of guilt, a shallow affect and antisocial behavior.

The study appears in the Journal of the American Academy of Child and Adolescent Psychiatry.

“Some of the early work on callous-unemotional traits focused on their biological bases, like genetics and the brain, making the argument that these traits develop regardless of what is happening in a child’s environment, that parenting doesn’t matter,” said Waller.

“We felt there must be something we could change in the environment that might prevent a susceptible child from going down the pathway to more severe antisocial behavior.”

The work is the latest in a series of studies from Waller and colleagues using direct observation to assess a variety of aspects of parenting. The initial research, which considered a biological parent and child, confirmed that parental warmth plays a significant role in whether CU traits materialize.

A subsequent adoption study, of parents and children who were not biologically related, provided similar results.

“We couldn’t blame genetics, because these children don’t share genes with their parents,” Waller stated. “But this doesn’t rule out the possibility that something about the child’s genetic characteristics was evoking certain reactions from the adoptive parent.”

In other words, a parent who is warm and positive may have a hard time maintaining those behaviors if the child never reciprocates.

Knowing this led Waller to turn to a study of 6-to-11-year-old participants from a large, ongoing study of identical twins directed by Dr. S. Alexandra Burt at Michigan State University. For 454 children (227 sets of identical twins), parents completed a 50-item questionnaire about the home environment.

They also established their harshness and warmth levels by rating 24 statements such as “I often lose my temper with my child” and “My child knows I love him/her.” The researchers assessed child behavior by asking the mother to report on 35 traits related to aggression and CU traits.

“The study convincingly shows that parenting and not just genes contributes to the development of risky callous-unemotional traits,” said Hyde. “Identical twins have the same DNA, so we can be more certain that the differences in parenting the twins received affect the development of these traits.”

A potential next step is to turn these findings into useable interventions for families trying to prevent a child from developing such traits, or to improve troubling behaviors that have already begun, according to Waller.

“From a real-world standpoint, creating interventions that work practically and are actually able to change behaviors in different types of families is complicated,” concluded Waller. “These results show that small differences in how parents care for their children matters.”

The researchers acknowledge there are some limitations to the study, for example that it skews heavily towards two-parent families, meaning the findings may not be as generalizable to single-parent homes. It also assesses parenting measures and twin behaviors based solely on parenting reports.
