Free test · ASRS-6 + RAADS-14
AuDHD is the informal name for having both autism and ADHD. No validated AuDHD test exists, so this page runs two validated screeners back to back, ASRS-6 for ADHD and RAADS-14 for autism, and shows both scores. It is a screening, not a diagnosis.
Check the box to start.
Two separate scales, one after the other. The ASRS-6 asks how often attention, organization and restlessness have been a problem over the last 6 months. The RAADS-14 asks how true statements about social contact, senses and habits are for you now and were in childhood.
A screener shows whether it is worth looking further. Neither scale can diagnose ADHD or autism, and each condition can raise the other’s score. Only a clinician who assesses both can tell them apart.

ASRS-6ADHD
How often attention, organization and restlessness have been a problem over the last 6 months. Developed with the World Health Organization. A score of 4 or more out of 6 is above the screening threshold.
Take the ADHD test on its own
RAADS-14Autism
How true statements about social contact, sensory overload and habits are for you now and were in childhood. Developed in Sweden from the longer RAADS-R. A score of 14 or more out of 42 is above the screening threshold.
Take the autism test on its ownNo. AuDHD is an informal word for being autistic and having ADHD, not a diagnosis in DSM-5-TR or ICD-11, where the two are separate conditions.
Since the DSM-5 in 2013, clinicians can diagnose both in the same person. What no questionnaire has been validated to do is detect the combination. What can be screened is each condition on its own, so the honest version of an AuDHD test is what this page does: two validated screeners, each reported separately, side by side.
ADHD is mainly about attention, impulse control and activity level. Autism is mainly about social communication, sensory differences and a strong need for sameness.
In everyday life the two overlap enough that each can look like the other. That is why a high score on one screener may partly come from the other condition, and why only a clinician who assesses both can tell them apart. Both screeners carry that warning: many people without autism, especially with ADHD or anxiety, score high on the RAADS-14, and stress, anxiety and lack of sleep cause difficulties like the ones the ASRS-6 asks about.
Far more often than in a comparison group: in a US Medicaid study of more than 3.5 million adults, 26.7% of autistic adults without intellectual disability had an ADHD diagnosis, against 2.7% in a general Medicaid comparison group.
The figure comes from Yerys and colleagues (JAMA Network Open, 2025) and counts recorded diagnoses, not everyone who has the traits.
Neither is accurate enough to decide anything on its own. They are built to show whether an assessment is worth considering.
ASRS-6. In its original study (Kessler and colleagues, 2005) it caught about 7 in 10 adults whom clinicians rated as having ADHD and rarely flagged anyone else. A low score can still miss ADHD.
RAADS-14. With the threshold of 14 it caught 97% of autistic adults in its main validation group (Eriksson and colleagues, 2013). It also flags many people without autism: only 46% of adults with ADHD and no autism, and 64% of other psychiatric patients, scored below the threshold, against 95% of people with no psychiatric diagnosis. A high score says little on its own.
Read the two results together, and treat each as a prompt for a conversation, not a label.
Your answers are above the threshold on both screeners. That fits AuDHD, but it also fits ADHD alone: in the RAADS-14 validation study, more than half of adults with ADHD and no autism scored 14 or more. Only an assessment can tell them apart.
Your ADHD screener is above its threshold and your autism screener is below. A screener cannot rule a condition out, so if autism fits your experience, mention both when you talk to a professional.
Your autism screener is above its threshold and your ADHD screener is below. The RAADS-14 flags many people without autism, and the ASRS-6 misses some people with ADHD (in its original study it caught about 7 in 10), so neither result settles anything. If attention is still a daily problem, say so.
Neither screener points to ADHD or to autistic traits. Screeners miss some people, so if attention, organization, social situations or sensory overload still get in your way, you can talk to a professional with a low score.
Questions
Yes. Since 2013 the DSM-5 allows both diagnoses in one person, and ICD-11 does too. A clinician looks at both, because each can look like the other.
No. It means both screeners are above their thresholds. A screener only shows whether it is worth looking further, and each condition can raise the other’s score. Only an assessment can say.
Take that result to a professional and mention the other too. A low RAADS-14 score does not rule autism out, and a low ASRS-6 score does not rule ADHD out.
No. Your score is calculated in your browser. Your answers are not sent to our server and are not saved: if you close the page, they are gone.
Yes. The adult ADHD test (ASRS-6) and the autism test for adults (RAADS-14) each have their own page, with the same questions.
For therapists
Sessio lets you send each of these scales to a client as a link, and the client needs no sign-up. The score and the answer to every item come to you by email. The two screeners are sent separately.
