Free ADHD Self-Assessment Test for Adults

Attention Deficit Hyperactivity Disorder (ADHD) affects an estimated 8.7 million adults in the United States, yet the majority remain undiagnosed well into adulthood. Unlike the hyperactive child bouncing off the walls — the image most people associate with ADHD — adult symptoms are far more subtle. They show up as chronic procrastination, missed deadlines, difficulty following conversations, impulsive financial decisions, and an overwhelming sense that you are not living up to your potential despite being intelligent and capable.

This free self-assessment is based on the World Health Organization’s Adult ADHD Self-Report Scale (ASRS v1.1), a validated six-question screening tool developed in collaboration with researchers at Harvard Medical School and New York University. It is used globally by clinicians as a first-pass screener to determine whether a full diagnostic evaluation is warranted. The questions below focus on the core symptom domains of inattention, hyperactivity, and impulsivity as defined by the DSM-5. It takes less than two minutes, your answers are never stored, and you will receive your results instantly on this page.

Understanding the ASRS v1.1 Screening Tool

The Adult ADHD Self-Report Scale (ASRS v1.1) was developed by the World Health Organization in collaboration with researchers at Harvard Medical School and New York University. It is one of the most widely used ADHD screening instruments in the world, translated into dozens of languages and referenced in clinical guidelines across multiple countries. The six questions in Part A of the ASRS are specifically designed to capture the symptoms most predictive of an ADHD diagnosis in adults.

The screener evaluates two core symptom domains. Questions one through three assess inattention — difficulties with task completion, organization, and memory that go beyond ordinary forgetfulness. Questions four through six assess hyperactivity and impulsivity — patterns of avoidance, physical restlessness, and a feeling of being internally driven that interferes with daily life. These domains correspond directly to the DSM-5 diagnostic criteria for ADHD, which distinguishes between the Predominantly Inattentive presentation, the Predominantly Hyperactive-Impulsive presentation, and the Combined presentation.

It is important to note that a high score on this screener does not mean you have ADHD. Many conditions — including anxiety, depression, sleep disorders, thyroid dysfunction, and chronic stress — can produce symptoms that overlap significantly with ADHD. A comprehensive diagnostic evaluation by a licensed clinician typically includes a detailed clinical interview, a review of childhood developmental history, collateral information from family or partners, and often standardized neuropsychological testing to rule out other explanations.

What to Do Next

If your score falls in the moderate or high range, the single most impactful step you can take is to talk to a professional. Many clinicians now offer telehealth evaluations, making access easier regardless of where you live. A comprehensive evaluation can clarify whether ADHD is the right explanation for your experiences and open the door to treatment options — including therapy, medication, coaching, or environmental modifications — that have a very high success rate in adults.

You do not need to have a confirmed diagnosis to reach out. If the patterns described in this screener feel familiar, that alone is reason enough to explore further. Use the form below to book a free, no-obligation consultation with a licensed clinician in our network.
