Autism screening tools

These free resources include the original Autism Quotient test I undertook when I first suspected I might be Autistic. I provide them in that spirit; essentially for those of you who might suspect, who may have suspected for sometime, but do not know.

• Autism Quotient (AQ)
• The Ritvo Autism Asperger's Diagnostic Scale (RAADS)
• Camouflaging Autistic Traits Questionnaire (CAT-Q)
• Adult Repetitive Behaviours Questionnaire-2 (RBQ-2)

Autism Quotient (AQ)

This diagnostic questionnaire has been designed to measure Autistic traits. It’s the screening tool I first used – the one that started it all. I think I ended up taking it about 10 times because I couldn’t believe how I was scoring!

The Ritvo Autism Asperger’s Diagnostic Scale (RAADS)

The RAADS formed part of my official Autism assessment at the end of 2022. The comments from the results stated: Glenn’s score of 28 is well above the cut-off score of 14 that indicates a full assessment is warranted. The RAADS is a screening tool designed specifically for adults, particularly those who earlier in life missed being diagnosed Autistic, which was the case for me.

Camouflaging Autistic Traits Questionnaire

(CAT-Q) The CAT-Q measures the degree to which you might be using camouflaging or ‘masking’ strategies. I cover this in detail in my article ‘What is Autistic masking and why do we do it?‘ You can access the relevant journal article about the CAT-Q here: Camouflaging in Autism: Age Effects and Cross-Cultural Validation of the Camouflaging Autistic Traits Questionnaire (CAT-Q)

Adult Repetitive Behaviours Questionnaire-2 (RBQ-2)

This was another test that formed part of my formal Autism assessment. The RBQ-2 questionnaire measures repetitive behaviours in adults. It’s a short test, but you have to score it yourself when you’ve completed it.
