Overview

• UCL researchers found that parents' genetic predispositions indirectly shape children's educational and mental health outcomes through environmental influences.
• The study reviewed data from 38,654 families across five countries and analyzed genetic data from 4,580 UK families using polygenic scoring methods.
• Parental non-cognitive traits, such as motivation and self-control, had the strongest impact on children around age three, emphasizing the importance of early childhood environments.
• Controlling for socioeconomic status and parental education reduced observed genetic effects by approximately 75%, underscoring the role of family resources.
• The findings support calls for early parent-focused interventions and sustained child-centered support, aligning with UK Government life-course mental health strategies.
