Note: Boldface indicates significant mediation. ADHD = attention-deficit/hyperactivity disorder; Point est. = point estimate of the indirect effect; BC Bootstrap CI = bias corrected confidence intervals; CBCL/TRF = mean composite parent and teacher ratings on the Child Behavior Checklist and Teacher Report Form; DISC = parent reports on the Diagnostic Interview Schedule for Children.
