Question: Would students with reading disorder have a significantly higher prevalence of attention-deficit/hyperactiveimpulsive disorder (ADHD) symptoms than neurotypical students? Finding: Students at risk of reading disorder exhibited significant ADHD symptoms compared with those not at risk of reading disorder according to all presentations of teacher assessments versus only for predominantly inattentive presentations of the parental assessments. Meaning: Students with reading disorder have a significantly higher prevalence of ADHD symptoms than neurotypical students. Sex, parental education level, average family income, and children’s school affiliation significantly influenced reading disorder prevalence. |
