The IDRlabs Autism Spectrum Quotient Test (IDR-AQT) was developed by IDRlabs. The IDR-AQT is based on the work of Simon Baron-Cohen, Ph.D. and Sally Wheelwright, Ph.D., who created the Autism Spectrum Quotient Test. The IDR-AQT is not associated with any specific researchers in the field of psychopathology or any affiliated research institutions.

The IDRlabs Autism Spectrum Quotient Test was informed by the AQ’s criteria for autism spectrum traits, as published in Baron-Cohen, Simon & Hoekstra, Rosa & Knickmeyer, Rebecca & Wheelwright, Sally. (2006). The Autism-Spectrum Quotient (AQ)—Adolescent Version. Journal of autism and developmental disorders. 36. 343-50. 10.1007/s10803-006-0073-6. Simon Baron-Cohen, et al.

The work of Dr. Baron-Cohen and Dr. Wheelwright has also informed some of the diagnostic criteria in the form of the widely used psychological instrument, the AQ for clinical use, especially by qualified mental health professionals. The present test is intended for educational purposes only. IDRlabs and the present IDRlabs Autism Spectrum Quotient Test are independent of the above researchers, organizations, or their affiliated institutions.
