EDA-QA - Extreme Demand Avoidance Questionnaire for Adults

A free twenty-six-question self-assessment measuring demand avoidance traits in adults, taking about ten to fifteen minutes. You are asked to answer thinking about your behaviour over the last six months. There are no right or wrong answers. Your report is private and sent to you by email.

What demand avoidance means here

This is not ordinary procrastination or dislike of being told what to do. Demand avoidance in this sense describes something closer to a nervous-system response: an expectation, once it registers as a demand, produces a level of distress that makes complying feel genuinely impossible rather than merely unwelcome.

It applies to demands from other people, and often to demands a person places on themselves - which is the part that surprises people most. Something you want to do, that you chose, that you were looking forward to, can become unreachable the moment it turns into a thing you are supposed to do. Direct requests, deadlines, appointments and questions can all trigger it.

Where it is present, people frequently describe negotiating, distracting, changing the subject, giving an excuse, or withdrawing entirely - not as strategy but as what happens. It is commonly accompanied by a strong need for autonomy and control, and by considerable anxiety underneath.

A note on the name

The profile this questionnaire measures is usually called Pathological Demand Avoidance, or PDA. Many autistic adults dislike that name, and reasonably so - "pathological" frames a distress response as a defect of character, which is not what the underlying experience is.

A widely used alternative is Persistent Drive for Autonomy, which keeps the same initials and describes the same pattern from the inside rather than from the outside. Others simply say demand avoidance. We use the established term on this page because it is what the research and the questionnaire are named after and what people search for, but we think the objection to it is a fair one.

Where PDA stands diagnostically

This needs saying plainly, because the answer is not what most people assume.

PDA is not a formal diagnosis. It does not appear in the DSM-5 or in the ICD-11. It is best understood as a proposed profile - a described pattern that shows up within autism - rather than a separate condition with agreed criteria. It is recognised and used in parts of UK practice; elsewhere it is debated, and some clinicians and researchers question whether it is a distinct profile at all.

None of that means the experience is not real. People who recognise themselves in it recognise themselves very strongly, and the practical implications for how support should be offered are significant. But no score on this questionnaire, or any other, produces a diagnosis of PDA, because there is not one to produce.

What the EDA-QA is

The Extreme Demand Avoidance Questionnaire for Adults was developed by Vincent Egan and colleagues and published in 2019, adapted from the EDA-Q, which Elizabeth O’Nions and colleagues had designed for parents to complete about children.

Twenty-six statements, each rated from 0 to 3 by how true it is of you, giving a total between 0 and 78. It is a research instrument rather than a clinical one, and it is worth knowing that its own literature is cautious about it: EDA-QA scores correlate with autistic traits, but also with irritability and general negative affect, and how cleanly it separates demand avoidance from those has been questioned. A high score is a starting point for a conversation, not a finding.

Who it is for

Adults who recognise the pattern described above and want a structured way to look at it. Many people arrive here after an autism assessment or self-identification left something unexplained - specifically, why strategies that work for other autistic people, particularly structure and routine, sometimes make things worse rather than better.

It does not assess autism. If that is the question you are asking, the AQ-50, the RAADS-14 and the RBQ-2A are the places to start.

How it is scored

Your total runs from 0 to 78 and falls into one of three bands.

Low likelihood - 0 to 22

Few demand-avoidant traits reported.

Moderate traits - 23 to 44

Some traits present, below the threshold used in the research.

High likelihood - 45 to 78

At or above the research threshold of 45, indicating features consistent with the demand avoidance profile.

How to read the threshold of 45

Forty-five is a research convention, not a diagnostic line - there is no diagnosis for it to be a line for. It marks the point above which a group of people, in a study, resembled the described profile.

It is worth treating a score near the boundary lightly in either direction. What tends to be more informative than the number is whether the description above landed - and in particular whether the part about demands you place on yourself did. That specific recognition is what most distinguishes this pattern from ordinary avoidance or from burnout.

What this screener is not

This screening tool is for information and self-reflection only. It is not a diagnostic instrument and does not replace professional medical or psychological evaluation. It helps you reflect on demand-avoidance-related traits; it does not provide a formal mental health diagnosis.

Demand avoidance can also appear alongside anxiety disorders, trauma responses, ADHD and autistic burnout, and it can look similar from the outside in all of them while calling for quite different support. Sorting between those is a job for an assessment with a clinician, not a questionnaire.

What happens after you finish

You receive your score and a report by email. Nothing is shared with anyone unless you ask us to send it somewhere. If you would like to talk the result through, you can tell us at the end and we will follow up.

Working with us

We offer a demand avoidance evaluation as an add-on to a full assessment. Because PDA is a profile rather than a diagnosis, what that produces is a description of the pattern and its practical implications - what helps, what backfires, and how to explain it to the people around you - rather than a diagnostic label.

We also provide adult autism assessment, ADHD assessment, dual assessment for both, and an add-on evaluation for alexithymia. If you need documentation rather than a diagnosis, our page on neuroaffirming accommodations explains that process.

You can also meet the clinicians, read our frequently asked questions, or browse the rest of our free tools on the self-discovery page.

About Adult Autism Assessment

We assess and support neurodivergent adults - people seeking a first diagnosis in adulthood, people who have known for years and want documentation, and people who are still working out what fits. Our approach is neurodiversity-affirming: an assessment here is about accurate self-understanding and practical accommodation, not about finding out what is wrong with you.
