The cut-off score for the AQ-10 is 6 (out of 10 total questions). 88% of autistic individuals receive scores of 6 or above.

The shortened Autism Quotient (AQ-10) was created to speed up the screening process, containing only ten questions compared to the fifty questions in the original Autism Quotient.

The autism-spectrum quotient (AQ)

The RAADS-R is a diagnostic tool specifically geared toward identifying autistic individuals with a subclinical presentation. It nuances its grading scale by distinguishing between behaviors present in both adulthood and childhood, in adulthood only, and in childhood only. The RAADS-R has an especially high sensitivity, with 97% of autistic individuals being correctly identified by the inventory. 

RAADS-R

The CAT-Q is a diagnostic tool that measures how much an individual masks, or hides, autistic traits. It serves as a useful tool for identifying autistic individuals who are missed by other inventories due to the way that they mask. 

CAT-Q

The RBQ-2A is a diagnostic tool that measures the frequency of restrictive and repetitive behaviors, which is one of the key diagnostic criteria of autism spectrum disorder in the DSM-5. 

RBQ-2A 

The ADOS-2, Module 4 is one of the most frequently-used diagnostic tools for diagnosing adolescents and adults on the autism spectrum, involving a semi-structured interview between the evaluator and the person being evaluated. Its primary purpose is to assess a person’s social skills and to observe for any repetitive or restrictive behaviors. It is commonly used in conjunction with the ADI-R. 

ADOS-2, Module 4  

The Autism Quotient is one of the most commonly-used diagnostic tools in adults, with fifty questions relating to various diagnostic criteria for Autism Spectrum Disorder.
