RAADS-R

What is RAADS-R

The Ritvo Autism Asperger Diagnostic Scale–Revised (RAADS–R) is a self-report questionnaire designed to identify adult autistics who “escape diagnosis” due to a subclinical level presentation.

The test assesses developmental symptoms correlating with the three DSM-5 diagnostic categories (Language, Social relatedness, and Sensory–motor), as well as a fourth subscale, Circumscribed interests. It consists of 80 statements, giving you 4 choices for each statement:

  • True now and when I was young
  • True now only
  • True only when I was younger than 16
  • Never true

Who the test is designed for

  • Adults (age 16+) with ASD level 1 or subclinical autism.
  • Adults with IQ in the normal range (IQ >=80)

Total RAADA – S Score

A total RAADS–R score of 65 or higher is consistent with the diagnosis of autism and supports a clinician’s diagnosis. However, if there is a difference between the clinician’s diagnosis and the RAADS–R diagnostic assignment, the clinician’s diagnosis should take precedent. This is because symptoms may be revealed only during an interview.

Also, the RAADS–R standardization study reported that many autism subjects, particularly those in their late teens and early twenties, failed to acknowledge the presence of symptoms that their families said were present and which were readily observed by the diagnostician
