Primary use / Purpose: 

The AAA was developed for use in the diagnosis of Aspergers syndrome in adults.


While such instruments are already in place for children, there was a need to develop an instrument relevant for diagnoses in adulthood. The instrument is electronic and computer-scorable. In order to avoid false positives, the Adult Asperger Assessment (AAA) criteria are more conservative than the DSM-IV. The AAA includes 23 categorical items, with spaces to include how the symptom manifests in the individual.


Psychometrics are discussed in Baron-Cohen, Wheelwright, Robinson, and Woodbury-Smith (2005).
