Testing for ADHD/ADD

There is no single test to diagnose ADHD/ADD.

There are many reasons why someone may struggle with attention and focus.  We want to be sure that we are getting to the root of the problem and ensure that no other learning disabilities or processing issues are present.  Our evaluations take from 3-4 hours and do not center around just surveys and questionnaires.  Instead, our evaluation includes:

  • an assessment of how the individual learns and processes information.
  • an assessment of their academic skills to determine if there are any gaps present that may be causing inattention or are caused by the inattention.
  • observations of how the individual works and behaves such as focusing, planning, organizing and executing tasks, as well as movement throughout the evaluation.
  • surveys that cover a wide range of executive functioning skills as well as signs of depression and anxiety. It will also look at their relationship with peers and parents. In addition, we may send surveys to parents, teachers, or other observers like a spouse or a roommate to learn how others view the client’s behaviors and skills.
  • a discussion with the individual to learn how they feel about their own struggles and what is happening each day both in and outside of school/work.

As part of the comprehensive evaluation, we administer the Qb Test which is an objective measure of attention, impulsivity, and activity level.   Click here for information about the Qb Test.

Once we complete the evaluation, we can then determine if the individual meets the criteria required to be diagnosed with an attention deficit disorder. To be diagnosed with ADHD, individuals must have six of the nine characteristics in either or both DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) categories listed below.
