ADHD Assessment by Creyos: A Scientifically-Validated Protocol & Report


With greater awareness of attention deficit hyperactivity disorder (ADHD) among the public, clinicians face more requests from patients for ADHD testing. Widespread awareness, open conversations, and reduced stigma are all positives. But more people may be self-diagnosing ADHD, based on symptoms they learn about online.

So the pressure comes back to healthcare providers to offer clarity and accuracy around ADHD diagnosis. With a lot of subjective information out there, clinicians have an opportunity to use objective measures to give patients clear answers about their cognition and an appropriate path for treatment or referrals.

To meet the challenges of this rising demand, Creyos created a specific ADHD Clinical Protocol and Report, being made available right in the Creyos Health platform.

This report improves patient experiences and outcomes, while offering clinicians the confidence that comes with a protocol that is:

  • Scientifically validated
  • Built specifically to measure objective markers shown to be associated with ADHD
  • A set of objective measurements that complement subjective questionnaires
  • Effective for ongoing tracking of efficacy of medication and other treatment on cognition
  • Flexibly administered in clinic or at home

In this article, we’ll address the current state of ADHD diagnosis, share the scientific foundation of our assessment, and provide a step-by-step guide for administering and interpreting the Creyos Health ADHD Protocol and Report.

Please note: The Creyos ADHD Clinical Protocol and Report is not a standalone diagnostic tool. As with other Creyos Health assessments, any conclusions drawn from the Creyos ADHD Clinical Report should be paired with clinical interviews and observations, other mental health examinations or assessments administered, and other evaluations of the patient and/or the patient's family history.

The Rise of ADHD Diagnosis and Treatment

Current Research on the Prevalence of ADHD

Attention deficit hyperactivity disorder (ADHD) has become one of the most common conditions that healthcare providers deal with every day. As per this article in the National Library of Medicine, it is one of the fastest growing conditions, among youth in particular:

National population surveys reflect an increase in the prevalence [of ADHD] from 6.1% to 10.2% in the 20-year period from 1997 to 2016 and experts continue to debate the causes for this trend. On the one hand, while there are children whose diagnoses are irrefutable and undeniably require treatment, some experts worry about the risk of overdiagnosis and subsequent over-prescription of stimulants and other psychotropics. Like with most psychotropic medications, treatment consideration needs to be carefully weighed with regards to potential adverse outcomes.

Other studies are exploring whether instances of ADHD have only increased since the onset of the COVID-19 pandemic in 2020. The causes they cite include “a lack of structure and anxiety about COVID or jobs during the pandemic".

Challenging the Status Quo of ADHD Assessment

Patients want to know—what assessments are used to diagnose ADHD? With the readiness of social media information on ADHD, a person who identifies with the symptoms might first turn to a Google search for “ADHD tests online,” seeking to validate their experience.

As you can imagine, many online diagnostic tools don’t have scientific credibility. On the other hand, patients might feel hesitant to bring their concerns to a clinician because of the long and costly processes typically involved in getting an ADHD diagnosis:

While other computerized assessments for ADHD also exist, they often require:

  • More than 20 minutes to complete continuous performance tasks
  • ADHD specialists to administer assessments and interpret results
  • Hardware that restricts the setting for completing the tests

How is this impacting clinical workflows? Long wait times and high costs mean clinicians and patients often rely solely on brief ADHD questionnaires and/or clinical interviews to reach a diagnosis. Alone, these questionnaires offer subjective data which may not be enough to justify treatment. The process often leaves all parties wanting more concrete information.

Introducing the Creyos Health ADHD Clinical Protocol and Report

What is the Creyos ADHD Clinical Protocol and Report?

This new report is a direct result of feedback received from the Creyos community and is fundamentally different from the reports and protocols you may have used and reviewed to-date. Specifically, this new report involves five Creyos cognitive tasks that examine 14 specific markers of ADHD. It then highlights whether the individual is within or outside the typical range for each, making it easy to identify atypical performance on markers associated with ADHD.

What Does It Include?

Our new, pre-built ADHD protocol is different from any existing ADHD protocols you may have created or used in Creyos Health. It is made up of:

  • Four cognitive tests that efficiently measure aspects of attention and executive function
  • The Sustained Attention to Response Task (SART), a short continuous performance task
  • An optional, age-appropriate questionnaire

What Are The Benefits?

A key benefit of the ADHD Clinical Protocol and Report is that it takes less than 25 minutes to complete, making it easy for patients to be assessed in the appropriate setting for focus, either in clinic or at home.

The protocol also features the SART, a brand new, 6-minute task within the family of continuous performance tasks commonly used with ADHD populations. The entire ADHD assessment is pre-built and tailored to the condition, so clinicians can easily administer the tasks and produce an objective, precise evaluation.

As with all Creyos Health assessments, an easy-to-interpret report is instantly generated upon completion. The ADHD report you’ll receive:

  • Is scientifically validated and objective
  • Is based on extensive research (hundreds of papers using Creyos tasks have been published)
  • Conveys performance with respect to the typical range on specific ADHD markers, in addition to specific percentile ranks

The Science Behind The ADHD Clinical Protocol and Report

How We Built The ADHD Clinical Report

In speaking to healthcare providers, we consistently heard the need for an objective clinical report focused on ADHD. Our solution became clear: Use the latest neuroscience, drawn from over 350 peer-reviewed studies involving Creyos tasks, to develop a fast and efficient ADHD-focused protocol that results in a comprehensive, yet easy-to-interpret, report.

This ADHD protocol also draws from existing assessments including:

What are the 14 Markers of ADHD?

The Creyos ADHD protocol is focused on 14 markers—specific cognitive performance metrics within Creyos tasks that are associated with an ADHD diagnosis.

To find markers validated through scientifically-supported associations with ADHD, Creyos examined over 100 peer-reviewed papers. We found:

  • Ten markers derived from four existing Creyos cognitive tasks (Spatial Planning, Token Search, Feature Match, and Double Trouble).
  • Four more markers derived from the Sustained Attention to Response Task (SART), a task available exclusively as part of the Creyos ADHD protocol.

What is SART?

The SART is a common task used with the ADHD population, and is part of the continuous performance test family—that is, tasks that measure attention and response inhibition over longer periods of time.

As outlined in depth in the Creyos ADHD Clinical Report Science Guide, the SART has proven to be a valid and reliable measure of sustained attention. It specifically measures the ability to sustain mindful, conscious information processing, even in repetitive, boring or distracting situations.

Completing the SART is simple: numbers flash on the screen and patients must press the spacebar or click the "Go" button for all numbers except the number 3.

Depending on your patient’s age, the appropriate questionnaire will automatically be included, alongside scientifically validated tasks that are proved to correlate with ADHD via peer-reviewed academic papers.

How To Interpret The ADHD Report

Once your patient completes their assessment, you'll be able to access a simple, easy-to-read report focused on ADHD in the same ways as you always do—right from the patient’s details page or the general reports page. Rather than having the results spread out across assessment types, you’ll get a unified report that offers a summary, plus a deeper dive into performance on each task.

In this next section, we’ll walk you through how to find and read the report. For more in-depth information, please download the Creyos ADHD Clinical Report Interpretation Guide.

  1. Summary Page
  2. Markers
  3. Typical vs. Outside the Typical Range
  4. Optional Questionnaire Scoring
  5. Details Section

1. Summary Page: The first page of the report is a summary that you can use to quickly derive useful clinical insights. An executive summary appears at the top of the first page for a quick overview of the results.

2. Markers: On the summary page, the rows highlighted in orange flag when a marker is outside the typical range. This gives you an easy way to review the information that matters most. The executive summary at the top both verbally and visually shows how many markers were met for that particular section.

An overview of all data and metrics on the summary report is provided below:

3. Typical vs. Outside the Typical Range: Each marker has a threshold used to determine if a patient’s score falls outside the typical range. You can find these details under the Typical Range column.

The typical range corresponds to performance commonly associated with people who are not diagnosed with ADHD.

Outside the typical range corresponds, statistically speaking, to the patient’s performance being one standard deviation away from the mean, in the same direction as people diagnosed with ADHD in published studies.

4. Optional Questionnaire Scoring: If an ADHD questionnaire is included—such as the VADRS, SWAN, and ASRS—a total score is calculated, then compared to a threshold for symptoms consistent with ADHD and/or specific types of ADHD.

These questionnaires combine subjective input from the patient with a systematic method of tracking and recording symptoms over time.

Here is what the VADRS summary report looks like:

Behaviors tied to each individual response that indicate ADHD symptoms are also highlighted in the Details Section. This allows you to quickly see specific behavioural problems or issues that the patient is experiencing:

5. Details Section: The Details Section provides additional context behind each task and its associated markers, allowing you to assess how close or far away from the threshold the individual scored. Also included on the Details pages are references that speak to the validity of each marker in the report:

That covers the end-to-end experience for this new clinical report focused on ADHD.
