What is the diagnosis for ADHD Testing?

There are a number of assessments that are completed by physicians, parents, and teachers. No single scale or source should be used to make the diagnosis of ADHD. It requires information from multiple sources. These include the following:
  1. The Vanderbilt Assessment Scale is a tool which reviews symptoms associated with ADHD and other psychiatric diagnoses. This is generally completed by a teacher and a parent. This is primarily used for children in elementary school.
  2. Conners Scale is a symptom rating tool that can be used for children aged 2-18 years and is completed by teachers, parents, and even self-administered by adolescents.
  3. The child behavior checklist is also called the Achenbach Checklist and is completed by parents, teachers, and the child and is a subjective evaluation of behaviors consistent with ADHD.
