We developed our Diagnostic Evaluation with one goal in mind: to offer a completely confidential mental health assessment that can support an ADHD diagnosis.
In late 2024, we conducted a clinical study comparing our Diagnostic Evaluation’s diagnosis of ADHD in adults to the current standard of care — a clinical interview.
“This validation confirms that patients can rely on the accuracy of their online evaluation, knowing their path forward is based on trusted clinical evidence.”
Barry K. Herman, MD, MMM, Chief Medical Officer
For patients struggling with undiagnosed or undertreated ADHD, finding valid and accessible assessment and treatment can be challenging. While telehealth offers affordable care, concerns about the accuracy of online assessments have persisted.
Our clinical study, published in the Journal of Clinical Psychiatry in October 2025, demonstrates that our Diagnostic Evaluation is as effective as traditional methods in diagnosing ADHD in adults—paving the way for telehealth to help more patients take control of their lives.
“This study shows that technology can expand access to trusted mental health care. Patients no longer have to choose between convenience and quality — they can have both, and on their own terms.”
The Mentavi Mental Health Diagnostic Evaluation is clinically validated for diagnosing ADHD in adults, built on the same science and standards used in traditional, in-person assessments, but delivered through a digital, clinician-reviewed model.
In this video, Mentavi Health Chief Medical Officer Dr. Barry K. Herman explains how the evaluation works, what clinical validation really means, and why this milestone matters for making quality mental healthcare easier to access for everyone.
He’s joined by Mentavi Health CEO Keith Brophy, who shares how this groundbreaking study reinforces Mentavi’s mission to combine clinical rigor with innovation, expanding access while keeping human expertise at the center of care.

These terms refer to certain approaches to treat diagnosed ADHD. Mentavi Health / ADHD Online may provide stimulant approaches (certain medications under medical treatment that are generally considered Class II controlled substances) or non-stimulant approaches (medications generally not considered Class II, and/or therapy and coaching not related to medication).
A diagnosis and initial conversation with our treatment clinicians is key to the best path for you. The diagnosis is a key first step to determine if you have ADHD or other related conditions. Approximately 60% of patients with ADHD have co-occurring conditions such as anxiety or depression, for example. At the same time, patients who believe they have ADHD may not even have it. For those who do, there can be a variety of considerations into what kind of treatment works best to meet the patient where they’re at.
If you are not feeling right, your journey starts with the first step of diagnostic evaluation.
