Note. For ADHD status, 0 = no ADHD, 1 = ADHD. For sex, 0 = male, 1 = female. For race, 0 = non-White, 1 = White. Bolded estimates reflect statistically significant models without p-value correction. SR = self-report; CDS = cognitive disengagement syndrome; PR = parent-report; ADHD-IN = ADHD inattentive symptoms; ADHD-HI = ADHD hyperactive/impulsive symptoms.

Estimates that are significant with Bonferroni correction (p < .008).
