In recent years, much research has been done on psychosocial interventions for ADHD behavior. This shows that parent and teacher training for children, as well as skills training for adolescents, are the most effective. However, previous research by the PAINT consortium has shown that these treatments are rarely used in clinical practice (see PAINT-CAU). The aim of PAINT-I is to disseminate knowledge about effective treatments to parents, teachers, healthcare professionals and policy officers of municipalities. This way we hope that more families will have access to effective ADHD treatments.
