An abbreviated tool enables clinicians to quickly determine whether an adult has autism, a new study suggests1. The test could be used either as part of a comprehensive autism assessment or as an autism screen.
Clinicians can diagnose a person with autism by observing her, asking her to complete a self-assessment or interviewing her caregiver. An ideal assessment involves all three components.
The new tool, called the Developmental, Dimensional and Diagnostic Interview-Adult Version (3Di-Adult), involves a caregiver report. It is similar to a standard test called the Autism Diagnostic Interview-Revised (ADI-R). But the ADI-R takes about two hours to administer and, unlike the 3Di-Adult, does not reflect the updated criteria in the latest edition of the “Diagnostic and Statistical Manual of Mental Disorders.”
