First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether training primary care clinicians to diagnose autism in children aged 18 to 36 months can shorten the time from a positive screening to a final diagnosis. About 300 children will take part across multiple clinics. Researchers will compare diagnosis times and accuracy between trained and untrained clinicians.
