Note. N = 263. All models also adjust for medication use, employment status, and shift work. Neighborhood safety is scored as the mean of neighborhood safety in early childhood, middle childhood, and adolescent. Parent Education is scored from 1 (less than 8th grade) to 11 (professional degree or higher).
