Gene-environment interaction in ADHD traits: the role of school environment, personality, callousness-unemotional traits and satisfaction with life.

ABSTRACT: We investigated gene-environment interaction in ADHD traits, focusing on environmental variables related to personality traits, school environment, satisfaction with life, and callousness. Using data from 2170 16-year-old twins and state-of-the-art methodology to prevent spurious findings due to measurement scale artifacts, gene-environment interaction models were estimated separately for the two core ADHD dimensions, hyperactivity-impulsivity, and inattentiveness. Based on scores on the SWAN questionnaire, where high scores are reflective of low ADHD traits, results showed that additive genetic influences were more important in explaining individual differences in the degree of hyperactivity-impulsivity in twins with a high score on the trait conscientiousness than in twins with a moderat
