Note. N = 7,626. For sex, 0 = male, 1 = female. For race, 0 = non-White, 1 = White. For all PSQI variables, higher scores indicate worse sleep (the first seven outcome variables in the table are the seven PSQI component scores, whereas the eighth outcome variable is the PSQI total score). Within each sleep variable, regression coefficients with different superscripts among the mental health symptom dimensions differ significantly in relation to the outcome variable at p < .05. All analyses controlled for site. ADHD-HI = attention-deficit/hyperactivity disorder hyperactivity-impulsivity symptoms. ADHD-IN = attention-deficit/hyperactivity disorder inattention symptoms. ANX = anxiety symptoms. DEP = depressive symptoms. PSQI = Pittsburgh Sleep Quality Index.
