Abstract

Introduction and objective: Children’s aggression is a consequence of both genetic and environmental factors. For example, children of parents with ADHD are exposed not only to an increased genetic risk but also to a riskier child-rearing environment (Murray and Johnston 2006). Genes from the dopamine system are related to ADHD symptoms (Swanson et al. 2007). Moreover, the dopamine system seems to moderate the relationship between parental influence and the child’s aggression (Bakermans-Kranenburg and van IJzendoorn 2006). This study investigated the contribution of these two factors, i.e., the influence of child dopamine risk, the environmental risk related to the parental level of ADHD symptoms, and the interaction of these factors on aggression at the age of 4.5 years. Methods: The sample consisted of 104 4.5-year-old children from the BIDS longitudinal study. DNA samples were collected from each child to assess dopamine ADHD risk (DRD4 7 allele and/or DAT1 10/10 alleles). Parental
