A risk calculator to predict ADHD in young adulthood


This calculator will only provide accurate estimations for children aged less than 12 years old living in the UK or in the US. There is evidence for accurate prediction until 40% in population-based (nonclinical) samples and up to 70% in clinical samples. It showed low accuracy for children living in Brazil, and has not been tested in other countries.
