The 15 to 20 Minute 
Qb ADHD Computer Test

The medical field has spent decades attempting to define ADHD and determine how to best diagnose it. Dr. Neal has invested over thirty years answering the question “What is ADHD?” and researching how to measure the signs of ADHD in kids and adults. His ADHD assessment includes a comprehensive intake of rating scales, extensive history, and the Qb ADHD computer test.

The Qb Test is an advanced FDA cleared for diagnosis and treatment of ADHD. This computer test will help confirm the diagnosis of ADHD by measuring a person’s attention, impulsivity, and hyperactivity. We will also determine if other issues may be mimicking ADHD. If the client does not have ADHD, we will “break the code” to pinpoint exactly what may be presenting similar struggles with inattention, impulsivity, or hyperactivity, so that we can address it.

The Qb ADHD computer test is a valuable diagnostic tool that offers quantitative data to bolster the qualitative interviews and assessments. This computer test also gives us a baseline to precisely measure inattention, impulsiveness, and hyperactivity. Based on the results of the test, we can determine whether the ADHD is mild or severe.

We use the Qb ADHD test because the information it gives is essential for determining between an ADHD diagnosis and another issue that may be mimicking ADHD. For the person considering medication or supplements to manage their ADHD symptoms, it is vital we have a baseline of the person’s performance off medication or supplements, so that we can accurately assess the level of their medication or supplements dosage. The Qb ADHD test helps us ensure a person is not under or over medicated, or using too much or little of a particular supplement.

What should you expect when you take the test?

You can take the test at the office or in your own home, on your own device. You will sit for a 15 to 20 minute period and play a simple video game task. The task measures your ability to sustain your attention and measure impulsiveness. Meanwhile, an infrared camera tracks any movements during the test. It is not like a video camera that records a video of you, but rather it only tracks your micro-movements while you are taking the test. The results are used to create a report that compares your results with data from other people of the same sex and age. This way you can see how you respond when you concentrate on a task compared with people who do not have ADHD.

What does the test look like?

During the test, a number of symbols are shown on the computer screen. The task is to push the responder button when a certain symbol appears on the screen. The test takes 15-20 minutes to complete and is not dependent on your language, reading or mathematical skills. Here's a shortened version of the test so you can see how it works.

Who makes QbTest?

QbTest is made by a Swedish company called Qbtech who specialize in ADHD testing software.  Backed by 30+ studies, QbTest is FDA cleared for diagnosis and treatment for ADHD for ages 6 to 60. It is one of the most advanced ADHD tests available and the only test that measures activity levels. We at NPS include this in our assessment for ADHD because we recognize that quantitative data is important in the diagnosis and the ongoing treatment for ADHD.

What do the results look like?

The green circles represent correct presses and the red squares represent incorrect presses. The vertical position of the symbols shows the reaction time. At the bottom of the report, all test results are summarized as numerical values. 

“Although my doctor suspected symptoms of ADD, I was never diagnosed. For me, the Qb Test was a really big eye opener because now there wasn’t just someone looking at me and noticing my struggles, there was a scientific foundation to it. I finally felt like someone was listening to me, and it was amazing to be able to show people I wasn’t making it all up.”

The test is a necessary part of our assessment and diagnosis for ADHD. It will objectively determine a person’s ability to focus and concentrate. It gives a measurement every 30 seconds of how well you are attending; if you have ADHD, then your brain is struggling to self regulate, which can sometimes create impulsiveness and will always create a significant distraction, which impairs our ability to focus and concentrate.

Do you know if your supplement or meds are giving you all the benefit you can get? Could you have even better focus or better working memory if your dosage was increased? Perhaps a different supplement or medication would help you even more? We want to ensure your treatment is working optimally. We never want a person overdosed and we never want a person under-dosed.

The first time you take the test you are not on any supplement or medication for attention. This is called a baseline test. We want to have a baseline test which aids in our assessment and diagnosis of ADHD. If you decide to use a supplement or medication, we will re-test while you are taking it and then we can compare the difference between the two tests and determine if you are receiving optimal benefit from what you are taking.

Yes, we would recommend you test after going on a new dosage increase. We follow the same protocol as with the first supplement or dosage you take. We do not, however, test every time a person raises the dosage level; we wait until there are significant benefits, and then we re-test. We never want to waste time and money on testing.

This specific computer test is still relatively new and is still being introduced to different parts of the United States. It has been out for several years and used overseas for many years. Dr. Neal started using the test in 2009.

We work very closely with the doctors we refer to. Per your request, your doctor gets a copy of your test and we explain the results of the test. Dr. Neal also communicates the results directly with your doctor and gives his recommendation regarding medications. Dr. Neal is not a medication prescriber. He can only give a recommendation based on his experience of working with clients who take medications. The final decision will always be between you and your medical prescriber. You would work directly with Dr. Neal if you are going to use supplements.

We have always found that the doctors we refer to appreciate the information this test gives. They have found that the test results help them in knowing from an objective standpoint if they need to increase your medication dosage or change medications because your current medication is not optimally beneficial.

There are other computer tests used in the assessment of ADHD. If you have already taken this same test, we would not retest for diagnosis. Sometimes even when a person has already taken a computer test we will still need to have them take the Qb ADHD test because it gives the type of information we need in determining whether the medication or supplement they are taking is the correct dosage or even the right one at all.

Yes, the results are extremely helpful. The test helps to measure a child’s impairment with executive functions (focus and concentration) and/or self-regulation (behavioral and emotional impulsiveness and hyperactivity).

Medications and supplements can be costly. Losing time in the classroom or at work is costly. The Qb ADHD test can bring enormous savings if you can determine you have ADHD and can ensure you are on the correct supplement or medication and dosage. Most of the time your insurance company will cover this test. But remember that you may have a deductible that needs to be met first, or a coinsurance payment.

Contrary to the prevailing thought, most people with ADHD are actually under-dosed. Being on the optimal dosage can bring peace, order, and success much sooner than waiting weeks to see if your medication is working. Many psychiatrists only make a medication change every 4–6 weeks. Our Qb computer test provides instant information so we can make a recommendation to your medical prescriber or adjust your supplements.
