What does the ADHD test measure?

The test assesses the three core areas of ADHD as described in the DSM diagnostic criteria:

  • Inattention: Difficulty maintaining attention, completing tasks, staying organized, or remembering appointments.
  • Hyperactivity: internal or external restlessness, a constant feeling of being driven, difficulty sitting still.
  • Impulsivity: acting hastily, interrupting others, having difficulty waiting.

The 18 questions in the ASRS v1.1 cover exactly these areas. Your answers will be evaluated to provide an initial assessment of whether there are signs of ADHD.

"The entire process was very structured and easy to understand."

I knew exactly what to expect at all times. Even during the consultations, I always felt understood and well taken care of. At no point did I feel like I wasn’t “right” or that I wasn’t being taken seriously. Thank you so much, GAM Medical!

"I felt well taken care of by the psychologists and psychotherapists at GAM Medical right from the start."

I was able to talk openly about my feelings and symptoms without feeling judged.

"I underwent a diagnostic evaluation and received comprehensive counseling at GAM Medical, and I'm thoroughly impressed."

From the very beginning, I felt that I was taken seriously, treated with respect, and received excellent professional care… I was particularly impressed by the time they took to address my concerns—without any pressure, but with a great deal of empathy and understanding.

Would you like more information about the test?

Here are detailed answers to the most frequently asked questions.

The questions are taken from the ASRS v1.1—a standardized screening questionnaire developed by the WHO and leading ADHD experts. It covers the three core areas of ADHD: attention problems, hyperactivity, and impulsivity. The results may indicate whether further professional evaluation is warranted. Important: The test provides an initial assessment but does not replace a comprehensive clinical diagnosis, such as the one we offer at GAM Medical.

Our online ADHD test can help you identify possible early signs of ADHD. It is based on clinical questions that are often used during a medical examination. However, it provides only an initial assessment. You can receive a detailed and reliable diagnosis from us.

Your privacy is very important to us! Our ADHD test is completely anonymous, and your data will not be shared with third parties. Everything you provide in the test remains confidential and is used solely for internal evaluation. If you request a diagnostic appointment, we will contact you using the information you provided.

The test takes about 3 to 5 minutes. It is designed to give you a reliable assessment in a short time without you having to fill out long questionnaires. The aim is to provide you with a quick and uncomplicated initial orientation.

If the test does not indicate ADHD, this does not mean that your problems should not be taken seriously. In this case too, you are welcome to come to us for a diagnostic test to find out whether the cause of your symptoms is ADHD (with accompanying illnesses).

An online test can help identify early signs of possible ADHD, based on proven screening questions used in clinical settings. However, it is only the first step. A reliable diagnosis requires a thorough evaluation by a doctor or psychologist, which also takes into account the individual’s living environment and history of symptoms.

Don’t worry—a positive result isn’t a bad thing. The test simply indicates that it makes sense to consider professional diagnostic testing. With us, you can take this next step and receive comprehensive diagnostic testing without a long wait.

The test is completely free and non-binding. There are no hidden costs, and you’re under no obligation. If the test indicates ADHD, you can then decide whether you’d like to undergo a professional evaluation with us.

Our ADHD test is specifically designed for adults and is intended for people who suspect they may have ADHD as adults. Since ADHD often presents with different symptoms in children and adolescents and is diagnosed differently, this test is not suitable for children. If you suspect your child has signs of ADHD, we recommend that you contact a pediatrician or child psychologist who specializes in this area and can conduct a comprehensive, age-appropriate evaluation.

ADHD (Attention-Deficit/Hyperactivity Disorder) is a neuropsychological disorder that impairs the brain’s executive functions. Contrary to popular belief, ADHD does not affect only children—about 3 to 4% of adults in Germany live with ADHD, often without realizing it. The disorder is characterized by three core symptoms: attention problems, hyperactivity, and impulsivity. ADHD often presents differently in adults than it does in children—instead of outward restlessness, it is often characterized by an inner agitation, concentration difficulties, or emotional instability. ADHD is not a matter of willpower, but a recognized diagnosis that can be effectively managed with the right support.

ADHD often manifests itself more subtly in adults than in children. Many people with ADHD have developed strategies over the years to compensate for their symptoms—which makes it harder to recognize. Typical signs in adulthood include:

  • Difficulty concentrating and being easily distracted
  • Inner restlessness or a constant feeling of being driven
  • Difficulty organizing tasks and setting priorities
  • Frequent putting off of tasks (“procrastination”)
  • Forgetfulness in Everyday Life (Appointments, Keys, Plans)
  • Impulsive decisions, such as spontaneous purchases
  • Rapid mood swings and emotional overreactions
  • Difficulty paying attention during longer conversations

Not all symptoms need to occur at the same time. What matters is that they are persistent and noticeably interfere with daily life. If you recognize yourself in several of these points, our free ADHD test can provide some initial guidance.

More About ADHD Symptoms in Adults

An online self-assessment like ours provides an initial evaluation—but a professional evaluation is needed for a definitive diagnosis. At GAM Medical, this process typically involves three in-depth consultations with specialized psychologists and psychiatrists. Standardized methods are used, including structured interviews (e.g., based on the DIVA-5), psychometric questionnaires, and behavioral observations. Possible comorbid conditions, such as depression or anxiety disorders, are also taken into account as part of the differential diagnosis. At the end, you’ll receive a detailed report and—if applicable—an officially recognized diagnosis. The entire process takes place 100% online with us, without months-long wait times.

Here’s how the ADHD diagnostic process works at GAM Medical

For each question, select the answer that best describes how you have felt or behaved over the past 6 months.

  1. How often do you have trouble wrapping up the final details of a project after the difficult parts are done?
  2. How often do you have trouble getting things in order when you have a task that requires organization?
  3. How often do you have trouble remembering appointments or commitments?
  4. How often do you avoid or put off starting a task that requires a lot of thought?
  5. How often do you fidget or move your hands or feet when you have to sit for a long time?
  6. How often do you feel overly active and compelled to do things, as if you were powered by a motor?
  7. How often do you make careless mistakes when you have to work on a boring or difficult project?
  8. How often do you have trouble staying focused when you’re doing boring or repetitive tasks?
  9. How often do you have trouble concentrating on what people are saying to you, even when they’re speaking directly to you?
  10. How often do you misplace things at home or at work, or have trouble finding them?
  11. How often do you find yourself distracted by activities or noises in your surroundings?
  12. How often do you get up from your seat during meetings or in other situations where you’re expected to remain seated?
  13. How often do you feel restless or fidgety?
  14. How often do you have trouble unwinding and relaxing when you have time to yourself?
  15. How often do you find yourself talking too much in social situations?
  16. How often does it happen in a conversation that you finish your conversation partner’s sentences before they have a chance to finish them themselves?
  17. How often do you have trouble waiting for your turn?
  18. How often do you interrupt other people when they’re working or busy with other things?

Interpretation: The more frequently responses fall into the “Often” or “Very often” categories, the more likely the results are to indicate symptoms typical of ADHD. A notable result is a clue, not a diagnosis. A definitive diagnosis requires a professional evaluation, such as the one we offer at GAM Medical.
