Dr. Harries examines factors that contribute to aggressive behaviors, especially directed towards parents by children. His research highlights how early life experiences, such as maltreatment or substance use by parents, significantly increase the risk of such aggression. Additionally, he studies how issues like cognitive dysfunction and poor rehabilitation strategies impact aggression in individuals with brain injuries. By identifying these critical factors, his work aims to improve family support systems and develop effective interventions for those affected by aggression and violence.
Key findings
Children experiencing cognitive dysfunction have a heightened risk of parent-directed aggression, particularly if they face maltreatment or use substances.
Parents who consume alcohol are 29% more likely to experience violence from their children.
Among young people exhibiting child-to-parent violence, those with strong emotional responses and less parental monitoring are significantly more likely to engage in substance-involved violence.
One study found that children showing aggressive behaviors due to harsh family environments often carry these patterns into adulthood.
Research indicates that higher levels of fractional exhaled nitric oxide (FeNO) correlate with better lung function in patients with chronic obstructive pulmonary disease (COPD) when treated with inhaled corticosteroids.
