AuDHD Screening Test

This screening combines two validated instruments to assess both autism and ADHD traits.

Part 1: AQ-10 — 10 questions assessing autism spectrum traits

2

Part 2: ASRS v1.1 Screener — 6 questions assessing ADHD traits

Estimated time: 3 minutes

About This AuDHD Screening Test

This free online AuDHD screening combines two of the most well-validated brief screening instruments in clinical psychology:

AQ-10

The AQ-10 (Autism Spectrum Quotient — 10 Items) was developed by the Autism Research Centre at the University of Cambridge. Published in the Journal of the American Academy of Child and Adolescent Psychiatry in 2012, it has been validated with a sensitivity of 0.88 and specificity of 0.91, meaning it correctly identifies the vast majority of individuals who should seek further autism evaluation. The AQ-10 uses a 4-point response scale (Definitely Agree to Definitely Disagree) with binary scoring. A score of 6 or above out of 10 suggests that a more detailed autism assessment may be beneficial.

ASRS v1.1

The ASRS v1.1 Screener is the 6-question Part A of the Adult ADHD Self-Report Scale v1.1, developed with the World Health Organization and the Workgroup on Adult ADHD (Kessler et al., 2005). Each question asks how often something has happened over the past 6 months, from Never to Very Often. A total of 14 or more out of 24 is a positive screen — a reason to talk to a clinician, not a diagnosis.

Why combine both? Because AuDHD — the co-occurrence of autism and ADHD — affects 50-70% of autistic individuals, and these conditions are often missed when screened separately.

How We Calculate Your Results

Transparency is a core principle of this screening tool. Unlike many online tests that use proprietary or unexplained scoring systems, our AuDHD screening uses the exact scoring methods published in the original academic studies.

Autism Score (AQ-10): Each of the 10 autism-related questions is scored as 0 or 1. Questions 1, 7, 8, and 10 score 1 point for an 'Agree' response. Questions 2, 3, 4, 5, 6, and 9 score 1 point for a 'Disagree' response. Your total autism score ranges from 0 to 10.

ADHD Score (ASRS v1.1): Each of the 6 ADHD questions scores 0 (Never) to 4 (Very Often), and the scores are added up. Your total ADHD score ranges from 0 to 24; 14 or more is a positive screen. This follows the scoring Harvard published in 2024.

Your result shows both scores independently, giving you a dual-dimension view of your neurodivergent traits. We provide interpretation based on the clinical cutoff thresholds established in the original research — not our own arbitrary categories.

Frequently Asked Questions About This Test

Is this test clinically validated?
This screening uses two instruments that have been independently validated in peer-reviewed research. The AQ-10 was validated with a sensitivity of 0.88 and specificity of 0.91 (Allison et al., 2012). The ASRS v1.1 Screener, at a score of 14 or more, showed 64.9% sensitivity and 94.0% specificity in a 2007 study of US health-plan members (Kessler et al., 2007). We score each with its published method — for the ASRS v1.1, the 0–24 scoring Harvard published in 2024.
Do I need an account or an email?
No account is needed. We ask for an email to show your results and send you a link back to them; we don't use it for marketing and never sell it.
How long does the test take?
Most people complete the 16 questions in 2 to 4 minutes. There is no time limit — take as long as you need to consider each question carefully.
Can I take this test for someone else?
This screening is designed as a self-report tool. The questions ask about your own personal experience and perception. While you can answer on behalf of someone else, the results may be less accurate because self-report tools rely on the individual's own self-awareness.
What should I do with my results?
If your results indicate elevated autistic or ADHD traits, consider discussing them with a healthcare professional who specializes in neurodevelopmental conditions. Your screening results can be a useful starting point for that conversation.
Is my data stored or shared?
Your test responses are stored securely to generate your results and allow you to access them via your unique results link. We do not sell or share your data with third parties.
How accurate is this screening compared to a full clinical assessment?
Brief screening tools like the AQ-10 and ASRS v1.1 Screener are designed to identify individuals who may benefit from a full assessment. They are not substitutes for a comprehensive evaluation, which typically involves a detailed clinical interview, developmental history, and behavioral observation.
Can I retake the test?
Yes. You can retake the screening as many times as you like. However, we recommend answering based on your general, typical experience rather than how you feel on any particular day.
