Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition that develops in childhood and often lasts into adulthood, according to the U.S. Centers for Disease Control and Prevention (CDC) and the National Institute of Mental Health (NIMH). Its core features are persistent patterns of inattention, hyperactivity, and/or impulsivity that occur frequently and across multiple settings — at work, at home, and in relationships. Many adults reach mid-life never having been identified, because the popular stereotype of ADHD — a young child who cannot sit still in class — does not match how the condition often appears in adults. An adult ADHD test can be a useful starting point because it lets you reflect on your own patterns in a structured way and decide whether a fuller conversation with a qualified professional makes sense for you.

One of the most widely used adult ADHD screening tools is the Adult ADHD Self-Report Scale (ASRS) v1.1 6-Question Screener. It was developed in conjunction with the World Health Organization (WHO) and the Workgroup on Adult ADHD, which included researchers from NYU Langone Medical Center and Harvard Medical School. The screener is a short, six-item subset of the longer 18-question ASRS v1.1 scale, which was designed to align with DSM symptom criteria. The ASRS is a screener, not a diagnostic instrument. Its purpose is to help identify adults who may be at higher risk for ADHD and who might benefit from a fuller clinical conversation. A positive screen is an invitation to seek a qualified professional — not a conclusion. On this site, the official screener questions, response options, and scoring rules are used without modification.

After completing the adult ADHD test, you receive a screening band of Low, Moderate, or Elevated based on how many of your responses meet the screener's threshold. - A Low band suggests that few of your answers reached the screening threshold. It does not rule ADHD out, but it may mean that ADHD-like traits are less prominent in your self-report. - A Moderate band suggests that some answers met the threshold and that further reflection or professional input could be worthwhile. - An Elevated band suggests that several answers met the threshold and that speaking with a qualified professional may be a reasonable next step. None of these bands is a diagnosis. They describe how your self-reported answers map onto a widely used screening rule. Only a qualified professional can determine whether ADHD, or something else, best explains what you are experiencing.

ADHD in adults is often described in terms of two broad presentations, and many adults show a mix of both. - Predominantly inattentive presentation may show up as difficulty managing attention, completing lengthy or uninteresting tasks, staying organized, remembering routines, and following through on commitments such as returning calls, paying bills, or keeping appointments. - Predominantly hyperactive-impulsive presentation may show up as restlessness, difficulty relaxing, talking a great deal, interrupting, finishing other people's sentences, or acting on impulse before thinking something through. In adults, the threshold for these patterns is lower than in children: per DSM-5 guidance, five or more symptoms (rather than six) are considered for those 17 and older. The patterns must also cause meaningful difficulty in everyday functioning, not just occasional lapses.

The popular image of ADHD — a young child running and climbing, unable to stay seated — does not capture how the condition frequently appears in adults. The CDC notes that ADHD symptoms can change over time and may look different at older ages, and that hyperactivity in particular may decrease or appear as extreme restlessness rather than overt physical movement. For many adults, hyperactivity becomes internal: a feeling of being internally restless or fidgety, of being unable to be still for extended periods, or of carrying on mentally as though always "on the go." Others may perceive the person as restless or difficult to keep up with. Inattention, by contrast, may become more visible as adult responsibilities grow — long reports, paperwork, bills, and sustained focus at work can expose difficulties that classroom tasks once masked. This is one reason an adult ADHD test can be revealing: it asks about adult life, not school behavior.

A short self-screening tool is intentionally brief, and that brevity comes with limits. ADHD-like traits overlap substantially with other common experiences and conditions, and a screener cannot tell them apart. - Anxiety, depression, and chronic stress can all affect attention, follow-through, and restlessness. - Sleep problems and burnout can mimic inattention, low motivation, and mental fog. - Hormonal changes, certain medications, and thyroid or other medical conditions can also affect focus and energy. The CDC and NIMH both note that anxiety, depression, sleep problems, and learning difficulties frequently co-occur with — or resemble — ADHD, which can make the full clinical picture harder to untangle. A screener also relies entirely on self-report, which may be incomplete or shaped by how a person feels on a given day. This is why a screening result is a starting point, not a conclusion.

Consider speaking with a qualified healthcare professional — such as a primary care physician, a psychiatrist, or a licensed psychologist — if your screening result is Elevated, if your patterns cause meaningful difficulty at work or in relationships, or if these patterns have persisted since childhood. A full evaluation is more thorough than any short screener. The CDC describes it as typically including a checklist for rating ADHD symptoms and a review of the person's history of behavior and experiences, with attention to whether symptoms were present before age 12. A clinician may ask to gather information from a partner, family member, or close friend, and may conduct a medical and psychological exam to rule out other health problems that can cause similar symptoms, such as anxiety, depression, sleep disorders, or substance use. A qualified professional can also discuss evidence-based options if ADHD is confirmed, which the CDC notes may include medication, therapy or behavioral treatments, or a combination.

After the screener, FreeADHD.com offers an optional AI personalized report. The report takes your structured, self-reported answers and explains them in plain language — describing the pattern your answers suggest, the everyday domains most likely affected, and questions worth raising with a qualified professional. The report is educational and is not a diagnosis. It does not decide whether you have ADHD, it does not recommend medication, and it does not replace a clinician. Its value is in helping you understand your own pattern clearly enough to act on it — whether that means seeking a full evaluation, adjusting habits, or simply thinking about your attention in a new way. If you are ready, the free adult ADHD test below takes only a few minutes and is based on the ASRS v1.1 6-question screener.
