NCT ID NCT05142826
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a program to help kindergarten teachers recognize that some children may be mistakenly diagnosed with ADHD simply because they are younger than their classmates. 62 children who were born just before the school cutoff date took part. Teachers learned about this age effect and used positive behavior support to help the children succeed. The goal was to see if this approach could reduce unnecessary ADHD diagnoses and medication use.
