Note. ADHD = attention-deficit/hyperactivity disorder; COSS = Children’s Organizational Skills Scales; HPC = Homework Problems Checklist; ODD = oppositional defiant disorder; SMH = school mental health; WAI = Working Alliance Inventory. WIAT = Wechsler Individual Achievement Test; WISC = Wechsler Intelligence Scale for Children.

Age is calculated in years.

For sex, boys = 0, girls = 1.

For ethnicity, non-Caucasian = 0, Caucasian = 1.

For ADHD medication use, no medication use = 0, medication use = 1.
