What is the ASRS?
Quick answer
ASRS is the Adult ADHD Self-Report Scale, a short questionnaire used to screen for ADHD symptoms in adults. In Canada, it may appear early in the care pathway, often before or during an ADHD assessment, but it does not diagnose ADHD on its own. A licensed clinician interprets it alongside history, impairment, and other assessment tools.

ASRS means a screening questionnaire
ASRS stands for Adult ADHD Self-Report Scale. It is a symptom checklist designed to help identify whether adult ADHD may be worth assessing more fully.
The ASRS is commonly used in primary care, mental health care, and ADHD-focused assessment settings. It asks about patterns such as attention problems, disorganization, restlessness, and impulsive behaviour over time.
Its main job is screening, not diagnosis. A high score can support the need for a fuller assessment, and a low score does not automatically rule ADHD out.
It usually comes before a full assessment
The ASRS often appears near the start of the assessment pathway. A clinic, family doctor, nurse practitioner, or mental health service may use it to organize symptoms before a full clinical review.
- You complete the questionnaire yourself.
- A clinician reviews the responses with your history, daily impairment, and other possible explanations.
- If needed, they use a more detailed interview or additional tools, such as the DIVA-5 or CAARS.
- They then decide whether a formal ADHD assessment is appropriate, or whether another condition, or more than one condition, needs attention.
At Finding Focus, the free self-assessment at /get-started/ is a screener only. It does not diagnose ADHD. For adults, the clinic’s formal assessment is a separate service completed by licensed Canadian nurse practitioners and clinicians working with Finding Focus.
It helps with screening, not proof
The ASRS can show whether your symptom pattern looks enough like adult ADHD to justify a closer look. It cannot prove that ADHD is the cause of your difficulties.
That matters because ADHD can overlap with other issues, including sleep problems, stress, trauma, learning difficulties, anxiety, depression, or substance-use concerns. If you need help now for safety, self-harm, substance use, depression, or suicidal thoughts, call or text 9-8-8 in Canada, or call 911 in an emergency.
| Can do | Cannot do |
|---|---|
| Screen for common adult ADHD symptoms | Confirm a diagnosis by itself |
| Support a decision to assess further | Show whether symptoms started in childhood on its own |
| Give a structured starting point for discussion | Measure every kind of impairment at work, school, or home |
| Track symptoms over time in some cases | Decide treatment on its own |
It shows up in several Canadian settings
In Canada, the ASRS may be used in private clinics, family practice, campus health, workplace-related health discussions, and specialty ADHD assessments. It is especially common when an adult is trying to sort out whether their struggles are consistent with ADHD or better explained another way.
For teens, clinicians may use different tools or adapt the assessment approach because school history, family input, and developmental context matter more directly. If a teen needs an assessment, see /adhd-assessments-for-teens/.
The term may also come up when someone is gathering records for accommodations at school or work, or for disability-related paperwork. Still, forms and benefits usually require clinical documentation, not just a screening score. For example, the Canada Revenue Agency’s Disability Tax Credit process uses Form T2201, which requires certification by a medical practitioner.

Common questions
Related questions, answered
No. The ASRS is a screening tool, not a diagnosis. A licensed clinician still needs to review your symptom history, how much your daily life is affected, whether symptoms were present earlier in life, and whether another condition could better explain what is happening.
Different clinicians may use it, including family physicians, nurse practitioners, psychologists, and ADHD assessment services. The ASRS itself is just one part of the process.
Yes, the ASRS was developed for adults. Teens are usually assessed with a broader developmental approach that may include parent input, school history, and different rating scales. That is one reason youth assessment pathways are often structured differently from adult ones.
A high score usually means a fuller ADHD assessment is worth discussing. It does not mean ADHD is certain, and it does not tell you what treatment you need. The next step is a clinical review that looks at symptoms, impairment, history, and other possible explanations.
