Improving accuracy of ADHD subtype diagnoses with the ADHD symptom rating scale.

Neuropsychologists evaluate children and adults with ADHD to establish a diagnosis, quantify cognitive deficits associated with ADHD and other common comorbid conditions, and provide recommendations for education and vocational planning. Standardized instruments that align with DSM ADHD symptom criteria are recommended for increasing ADHD diagnostic accuracy. This study examined whether a brief DSM-based symptom rating scale would assist in differentiating subtypes of ADHD.
