The Three-year Outcome of Emotional Symptoms in Clinically Referred Youth with ADHD and their Relationship to Neuropsychological Functions.

Background: Further knowledge is needed regarding long-term outcome of emotional symptoms, and the interplay between these symptoms and neuropsychological functioning in youth with attention deficit hyperactivity disorder (ADHD).

Objective: We aimed to explore the effect of performance-based neurocognitive functions and parent-rated behavioral executive functioning (EF) on self-rated and parent-rated internalizing symptoms longitudinally in clinically referred youth with ADHD (n = 137; mean age = 12.4 years).
