The Vanderbilt ADHD Diagnostic Rating Scale (VADRS) is a psychological assessment tool for attention deficit hyperactivity disorder (ADHD) symptoms and their effects on behavior and academic performance in children ages 6-12. This measure was developed by Mark Wolraich at the Oklahoma Health Sciences Center and includes items related to Oppositional Defiant Disorder, Conduct Disorder, Anxiety, and Depression, disorders often comorbid with ADHD.
There are two versions available: a parent form that contains 55 questions, and a teacher form that contains 43 questions. Comparing scores from the different versions of the VADRS with other psychological measures have suggested the scores have good but limited reliability and validity across multiple samples.
The Vanderbilt has been endorsed by the American Academy of Pediatrics as an appropriate evidence-based guideline for the diagnosis and treatment of children with ADHD. Since we get independent input from the parents and teachers we use this test as an adjunct to the Quotient test.
