Online ADHD Test for Adults

An ADHD screening tool is a brief questionnaire that determines if you have had symptoms common to adults with ADHD. It is not a medical diagnosis, but it can help you understand if your symptoms are interfering with your life and if you need to see a professional mental health provider. Screening tools are a helpful first step in deciding to seek a full assessment.

An ADHD self-test can help you identify patterns in your behavior or symptoms, but the self-reporting nature of the quiz limits the accuracy. These tools cannot identify other causes of concentration problems, such as anxiety, stress, or depression. However, these tools perform well in clinical settings with professional follow-up. This quiz is about 60-69% sensitive for detecting ADHD (depending on the population and study), meaning it identifies the disorder in up to 69% of people who have it. However, the test may also provide false positives, which makes professional evaluation even more essential.

This ADHD screener for adults is based on the longer 18-item Adult ADHD Self-Report Scale (ASRS). Evidence shows that this test is good at distinguishing ADHD from other problems, which is why it is widely used in clinical settings.

No. An online ADHD test alone cannot diagnose ADHD; a diagnosis requires a professional evaluation. This screening tool is only 6 questions, and a more formal assessment would consider the changes in symptoms over time, how much it affects your life, when it started (in childhood or adulthood), and rule out other conditions such as anxiety, depression, insomnia, or learning problems.
ADHD is diagnosed using the criteria from the Diagnostic and Statistical Manual, 5th Edition, which requires the presence of six common symptoms for 6+ months before the age of 12 (while an adult ADHD diagnosis requires five symptoms). They must interfere with daily functioning (social, academic, occupational) and occur in more than one setting (i.e., school, home, or work). Sometimes this evaluation includes loved ones’ and family members’ observations.

This ADHD test measures how often you experience symptoms of ADHD, such as inattention, disorganization, forgetfulness, restlessness, and impulsivity. Adults may present differently from children — the inattentive presentation of ADHD is more common and hyperactivity often becomes more internal (e.g., restlessness, racing thoughts). These symptoms may affect your performance at work and cause difficulties in relationships.

An adult ADHD screening test may be useful for anyone who has difficulty paying attention to important tasks or trouble organizing themselves for appointments and complicated projects, is impulsive or easily distracted, or seems to have a distorted sense of time (e.g., often being late for appointments or underestimating how long tasks will take). Sometimes these symptoms can be related to stress or anxiety, so it’s important to note how long they have been affecting performance and life. If you feel symptoms are affecting your work, social life, relationships, or self-esteem, it is especially important to take a screening test.

This screening tool checks for the main symptoms of adult ADHD, including inattention, hyperactivity, restlessness, and impulsivity. Adults with ADHD may act without thinking or have difficulty finishing projects, organizing themselves for complex tasks, and keeping up with appointments.

You can retake this ADHD self-assessment as often as you would like to see if your symptoms are improving with different interventions such as therapy, medication, or lifestyle modifications. However, it does not replace evaluation and treatment by a mental health professional.

Fewer than 4 checked boxes suggest that ADHD is less likely. Four or more checked boxes within the shaded region indicate that ADHD symptoms may be present and warrant professional evaluation. Because anxiety and other disorders can also cause some of these symptoms, a professional evaluation is important to confirm an ADHD diagnosis.

This ADHD quiz is based on the Adult ADHD Self-Report Scale, or ASRS. This test was developed by Ronald C. Kessler, Lenard Adler, and their colleagues. It has been widely studied and validated as a screening test in adult populations. This scale was developed in conjunction with the World Health Organization, using expert advice and statistical modeling to identify which items are most strongly associated with an ADHD diagnosis. The development process involved a 29-question item pool, plus 11 additional items assessing executive function, which were distilled to 6 items with the strongest association with a diagnosis of ADHD. Although the screening test is only 6 items, it is good at detecting ADHD and ruling out other causes.
