Free ADHD Test Online & Quiz

This free ADHD test uses the ASRS-v1.1 (Adult ADHD Self-Report Scale), a clinically validated ADHD screening tool developed by the World Health Organization (WHO) in conjunction with researchers at Harvard Medical School and New York University. It's one of the most widely used ADHD screening instruments for adults. While it's an accurate screening tool with good sensitivity and specificity for identifying adult ADHD, it's not a diagnostic test. Only a comprehensive evaluation by a qualified healthcare professional (psychiatrist, psychologist, or physician) can diagnose ADHD. This ADHD quiz is designed to help you identify if professional evaluation is warranted.

A high score on this ADHD test online (4 or more positive responses in Part A) suggests symptoms consistent with ADHD and indicates that professional evaluation is strongly recommended. However, it does NOT mean you definitely have ADHD. Many conditions can cause ADHD-like symptoms including anxiety, depression, sleep disorders, thyroid problems, chronic stress, or even substance use. Only a qualified healthcare professional can diagnose ADHD after conducting a comprehensive evaluation that includes medical history, clinical interviews, symptom assessment across multiple settings, and often input from family members. If you're wondering 'do I have ADHD?' this screening is a good first step, but professional assessment is necessary for diagnosis.

Yes, this free ADHD test online is completely confidential and anonymous. We do not collect, store, or share any of your ADHD quiz responses or results. Your answers remain entirely private on your device only. There's absolutely no registration, login, or personal information required to take this ADHD screening. No one will know you took this test unless you choose to tell them or share your results with a healthcare provider.

ADHD absolutely affects adults. While ADHD begins in childhood, it often persists into adulthood - approximately 60% of children with ADHD continue to have symptoms as adults. Many adults are diagnosed for the first time in their 30s, 40s, or even later, especially those with the predominantly inattentive type (less obvious hyperactivity). Adult ADHD symptoms often look different than childhood ADHD - physical hyperactivity may manifest as inner restlessness, and symptoms are often masked by coping strategies developed over years. This ADHD test online is specifically designed for adults and can help identify if your symptoms warrant professional evaluation.

If your ADHD quiz results indicate possible ADHD (4+ positive responses in Part A), we recommend: (1) Schedule an appointment with your primary care doctor or directly with a psychiatrist who specializes in ADHD, (2) Print or save your ADHD test results to share with your provider, (3) Prepare to discuss your symptoms from childhood to present (ADHD is lifelong), (4) Consider asking family members about symptoms they've observed, (5) Make a list of how symptoms affect your work, relationships, and daily life. Professional evaluation typically involves multiple appointments and may include rating scales, clinical interviews, and medical tests to rule out other conditions. If diagnosed, effective treatments including medication, therapy, and ADHD coaching are available.

Yes, you can retake this free ADHD screening as often as you like. Some people take it multiple times to see if results are consistent or to monitor symptoms over time. However, if you're repeatedly taking this ADHD test online because you're concerned about symptoms, that itself suggests you should seek professional evaluation rather than relying on self-screening. This test is most useful as an initial awareness tool to help you decide whether to pursue professional assessment, not as a substitute for ongoing clinical care.

Professional ADHD diagnosis involves much more than this brief ADHD quiz. A comprehensive evaluation typically includes: (1) Detailed clinical interview about current symptoms and their impact, (2) Review of childhood history (ADHD must be present since childhood), (3) Medical examination to rule out other conditions, (4) Standardized rating scales and questionnaires, (5) Often input from family members, partners, or close friends who can describe observed symptoms, (6) Assessment of symptoms across multiple settings (work, home, social), and (7) Evaluation for co-occurring conditions (anxiety, depression, learning disabilities). The process may take several appointments. Diagnosis is based on DSM-5 criteria which require persistent symptoms causing significant impairment in multiple areas of life.

ADD (Attention Deficit Disorder) is an outdated term. The current medical term is ADHD (Attention-Deficit/Hyperactivity Disorder) for all presentations. ADHD has three types: (1) Predominantly Inattentive Presentation (what used to be called ADD) - primarily attention and focus problems without obvious hyperactivity, (2) Predominantly Hyperactive-Impulsive Presentation - mainly restlessness and impulsivity, and (3) Combined Presentation - significant symptoms of both inattention and hyperactivity-impulsivity. Many adults, especially women, have the inattentive type which is often diagnosed later because symptoms are less disruptive. This ADHD test online assesses symptoms of all presentations.
