Note. Means are marginal estimates controlling for agency. Cohen’s d within groups is difference between baseline (BL) and follow-up (FU) divided by baseline pooled standard deviation. Boldface type indicates significant p values. alpha=05. C3RS = Conners 3 Rating Scale; H/I = Hyperactivity/Impulsivity; PT = post-treatment.
