OLS estimates of the association between an early elementary school ADHD diagnosis, medication treatment, and eighth grade reading achievement, by severity of ADHD-related behaviors.
Data Source: Early Childhood Longitudinal Study, Kindergarten Cohort of 1998-1999 (ECLS-K).
Notes: Our working sample consists of the children eligible for the kindergarten, first, third, fifth, and eighth grade survey rounds with non-missing information on ADHD diagnosis between kindergarten and third grade and 8th grade reading and math scores. Sample sizes are rounded to the nearest 10 in accordance with NCES restricted data requirements. Multiple imputation was used to handle item-missingness on all other predictors.
