Note. Parameter estimates, standard errors, and p-values are from linear regression analyses. In the interest of space, only interaction terms are reported. The linear 5HTTLPR code specifies specified that increased numbers of short or Lg alleles conferred the greatest sensitivity to the environment (high functioning= −1, intermediate functioning= 0, low functioning= 1). The nonlinear code specifies that both high and low functioning genotypes are associated with risk for ADHD and increased sensitivity to the environment (high functioning= −1, intermediate functioning= 2, low functioning= −1).
