made use of the FBAT-Interaction methodology (Vansteelandt et al. 2008). In total, 430,060 autosomal SNPs were included in the analysis, as were 909 patients (87% males) from complete trios. Mean age of the participants was 10.88 years, the average number of ADHD symptoms was 16.1, the mean overall measure for mother’s warmth was 1.43 (range from 0 to 3) and for maternal criticism it was 1.74 (range from 0 to 4). Additive, dominant and recessive genetic models were tested for the phenotype and the two environmental factors.
