Executive Functioning as a Mediator of Authoritarian Parenting and Child Externalized Behavior Problems

The first step in providing adequate prevention of children’s behavior problems is identifying possible predictors. There is an established relation between parenting style and behaviors and children’s future outcomes, including risk of externalizing behavior problems, but the mechanisms that may explain this relation are unclear. The current study investigated whether child executive functioning plays a mediating role between parenting style and externalizing behavior problems. I hypothesized that parenting style, specifically harsh authoritarian parenting, would predict a decrease in child executive performance, then leading to increased child behavior problems. Additionally, sex differences within this model were examined. Parenting styles and child externalizing behavior problems were measured through mother’s self-report within a sample of 322 low-income, Mexican-American mother child dyads in the Phoenix metropolitan area. A mediation model was performed, including relevant covariates, to test for significance of the mediated pathway. The results of the current study indicated that authoritarian parenting style significantly predicted greater externalizing behavior problems in the sample, but only for girls. Interestingly, it was also found that the addition of biological siblings predicted less behavior problems, again only for girls. These results promote understanding of the influences on behavior problems in children that can escalate to delinquency and criminal behavior. This information is critical for the development and improvement of strategic interventions.
