Adult ADHD Self-Report Scale (ASRS-18)
A validated 18-question screening tool developed by the World Health Organization to assess symptoms of Attention-Deficit/Hyperactivity Disorder in adults.
Who Is This Test For?
The ASRS is designed for adults who want to understand whether their attention, focus, or impulse control difficulties might be related to ADHD. It's commonly used as an initial screening in clinical settings.
- Adults who struggle with focus, organization, or completing tasks despite genuine effort
- Those who have wondered whether their attention difficulties might be more than normal distraction
- People who have been told they're 'scattered,' 'forgetful,' or 'always late'
- Anyone preparing to discuss attention or focus concerns with a healthcare provider
Please answer the questions below, rating yourself on each of the criteria shown using the scale. As you answer each question, consider how you have felt and conducted yourself over the past 6 months.
How often do you have trouble wrapping up the final details of a project, once the challenging parts have been done?
How often do you have difficulty getting things in order when you have to do a task that requires organization?
How often do you have problems remembering appointments or obligations?
When you have a task that requires a lot of thought, how often do you avoid or delay getting started?
How often do you fidget or squirm with your hands or feet when you have to sit down for a long time?
How often do you feel overly active and compelled to do things, like you were driven by a motor?
How often do you make careless mistakes when you have to work on a boring or difficult project?
How often do you have difficulty keeping your attention when you are doing boring or repetitive work?
How often do you have difficulty concentrating on what people say to you, even when they are speaking to you directly?
How often do you misplace or have difficulty finding things at home or at work?
How often are you distracted by activity or noise around you?
How often do you leave your seat in meetings or other situations in which you are expected to remain seated?
How often do you feel restless or fidgety?
How often do you have difficulty unwinding and relaxing when you have time to yourself?
How often do you find yourself talking too much when you are in social situations?
When you're in a conversation, how often do you find yourself finishing the sentences of the people you are talking to, before they can finish them themselves?
How often do you have difficulty waiting your turn in situations when turn taking is required?
How often do you interrupt others when they are busy?
Good To Know
External Systems Beat Internal Willpower
ADHD affects working memory and time awareness, making it hard to rely on mental reminders. External systems-timers, phone alerts, visible to-do lists, calendar blocks-work with your brain instead of against it. The goal isn't to 'try harder' but to build an environment that supports focus.
Movement Helps Focus
Physical activity isn't just good for health-it directly improves ADHD symptoms by boosting dopamine and norepinephrine. Even brief movement breaks, standing while working, or fidget tools can help. Many people with ADHD find they think better when their body isn't forced to be still.
Start Before You're Ready
The ADHD brain often struggles with task initiation, waiting for motivation that may never come. A practical workaround: commit to just 2 minutes of the task. Starting is the hardest part, and once you begin, continuing is easier. The motivation often follows the action, not the other way around.
Understanding the ASRS
T he Adult ADHD Self-Report Scale (ASRS) was developed by the World Health Organization (WHO) in collaboration with leading ADHD researchers including Dr. Ronald Kessler of Harvard Medical School. It is one of the most widely used and validated screening tools for ADHD in adults.
The ASRS consists of 18 questions that correspond to the DSM-5 criteria for ADHD. The first six questions (Part A) are the most predictive of the disorder and serve as an initial screener. The remaining twelve questions (Part B) provide additional insight into symptom severity and breadth.
Each question uses a five-point frequency scale from 'Never' to 'Very Often.' Your total score indicates the likelihood and severity of ADHD symptoms. Higher scores suggest a greater likelihood of ADHD, though only a qualified healthcare professional can make a formal diagnosis after comprehensive evaluation.
ADHD in adults often presents differently than in children. While hyperactivity may decrease with age, difficulties with attention, organization, time management, and impulse control frequently persist. Many adults with ADHD develop coping strategies that partially mask their symptoms.
Frequently Asked Questions
Can adults have ADHD?
Yes, ADHD is not just a childhood condition. Research shows that approximately 60% of children with ADHD continue to experience significant symptoms into adulthood. Additionally, many adults are diagnosed for the first time because their symptoms were missed or misunderstood in childhood, particularly among women and those without hyperactive symptoms.
How accurate is the ASRS?
The ASRS has strong psychometric properties. The 6-question screener (Part A) has 68.7% sensitivity and 99.5% specificity for detecting ADHD. The full 18-question version provides a more comprehensive picture of symptom severity. However, this is a screening tool, not a diagnostic instrument-only a qualified professional can diagnose ADHD.
What's the difference between ADHD and normal distraction?
Everyone experiences occasional distraction, forgetfulness, or restlessness. ADHD is different because symptoms are persistent (present since childhood), pervasive (affecting multiple life areas), and impairing (causing significant problems at work, school, or in relationships). The key distinction is the consistency and severity of the pattern.
Should I see a doctor about my results?
If your score suggests moderate or higher symptoms, or if attention and focus problems are significantly affecting your quality of life, professional evaluation is recommended. Bring your ASRS results to your appointment-many clinicians use this tool and will find your responses helpful for discussion.
Is ADHD treatable in adults?
Yes, ADHD is one of the most treatable mental health conditions. Treatment options include medication (which is effective for 70-80% of adults with ADHD), behavioral strategies, coaching, and therapy. Many adults report significant improvements in focus, organization, and quality of life with appropriate treatment.
