The effects of gene-environment interactions (GxE) on retrospective measures of ADHD have largely been neglected in the empirical literature. Data from a genetically-sensitive subsample of the National Longitudinal Study of Adolescent Health (Add Health) are used to determine if there is a GxE interaction between the dopamine D2 receptor (DRD2) polymorphism and delinquent peers on ADHD. The results suggest that the DRD2 polymorphism has a significant effect on ADHD for males. Further, the findings reveal that the effect of DRD2 on ADHD is conditioned by the number of drug-using friends an adolescent male has in his peer network. These results will be discussed in the context of the importance of analyzing genetic and environmental factors when studying ADHD. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]
