RAADS-R vs AQ: Which Adult Autism Screen to Take

Two tools, two jobs

Adults hunting for a serious autism screen usually meet two acronyms: RAADS-R (Ritvo Autism Asperger Diagnostic Scale–Revised) and the AQ (Autism Spectrum Quotient, often the 50-item Baron-Cohen version). They are not interchangeable, and neither one is a diagnosis.

RAADS-R is the scale this site runs: 80 statements, scores 0–240, four domains, a commonly cited cutoff of 65, and wording that asks what was true when you were young as well as what is true now. Start here: RAADS-R test.

The AQ is a trait questionnaire. It is shorter, widely used in research, and often treated as a first pass. It does not give you the same domain story RAADS-R does, and its popular “over 32” style thresholds are a different scoring universe—not a converted RAADS-R score.

If you only wanted the 14-item sibling of Ritvo’s scale, that comparison lives in RAADS-R vs RAADS-14.

When RAADS-R is the better next click

Choose the full RAADS-R when you need a picture you can actually discuss:

• You want subscales, not only a blob of “high” or “low”
• You suspect masking and need childhood items, not only today’s persona
• You may show the result to a GP, therapist, or adult-assessment clinician
• You already know a five-minute quiz will not settle anything

That extra time (usually 15–20 minutes) is the product. Sensory-motor and circumscribed-interest items are where many late-identified adults recognise themselves after years of “I am just awkward.”

How to avoid scoring the mask instead of the person: How to answer the RAADS-R.

When the AQ still earns a place

The AQ is useful when friction is the enemy.

• You want a shorter trait snapshot before committing an evening
• You are reading papers or forums that quote AQ numbers and want a comparable score
• You already have a RAADS-R result and want a second, independent screen

Treat it as a different camera, not a better one. A low AQ and a high RAADS-R (or the reverse) usually means the instruments are capturing different slices—not that one of them “caught you lying.”

Shared limits so you do not over-trust either

• Masking can flatten both
• ADHD, anxiety, and trauma overlap both (see Autism or ADHD?)
• Online self-administration is not the same as a supervised clinical battery
• Cutoffs are research tools. They are not pass/fail identities

If you sit near 65 on RAADS-R, read RAADS-R cutoff explained before you treat 64 and 66 as different species.

A blunt decision rule

• Want the most useful adult screen on this site → RAADS-R
• Want a quick trait number you will see cited elsewhere → AQ, then RAADS-R if anything resonates
• Already holding both → interpret pattern and history, not the prettier total

The serious work after any screen is the same: a timeline, domain notes, and—if you want clinical clarity—a professional who sees adults. The test only organises the questions.
