Note: N = 162. All steps are incremental, where variables in previous steps are included in the model at that step, but not presented in the table to preserve space (i.e., the table reflects the results of the final model with all predictors included). FSIQ = Full Scale Intelligence Quotient; SES = social economic status; IA = Inattention symptoms; HI = Hyperactive-impulsive symptoms; ODD = Oppositional Defiant Disorder symptoms. R² change effect size conventions: .01 = small, .06 = medium, .14 = large (Cohen et al., 2003).
