Description: The Autism Diagnostic Interview Revised (ADI-R) is a comprehensive interview that provides a thorough assessment of individuals suspected of having autism or other autism spectrum disorders. The ADI-R has proven highly useful for formal diagnosis as well as treatment and educational planning. To adminsiter the ADI-R, an experienced clinical interviewer questions a parent or caretaker who is familiar with the developmental history and current behaviour of the individual being evaluated. The interview can be used to assess both children and adults, as long as their mental age is above 2 years, 0 months.

 

Three Functional Domains are evaluated using 93 itmes:

  • Lanuage/Communication
  • Reciprocal Social Interactions
  • Restricted, Repetitive, and Stereotyped Behaviours and Interests

Following highly standardized procedures, the interviewer records and codes the informant’s responses. Interview questions cover eight content areas:

  • The subject’s background, including family, education, previous diagnoses and medications
  • Overview of the subject’s behaviour
  • Early development and developmental milstones
  • Language acquistion and loss of language or other skills
  • Current functioning in regard to language and communication
  • Social development and play
  • Interests and behaviours
  • Clinically relevent behaviours such as aggression, self-injury and possible epileptic features

Typically administration and scoring require from 1.5 to 2.5 hours. Administration and coding of the ADI-R are highly standardized and valid assessment requires training through thr study of the DVDs and Guidebook (N.B The PRC does not currently have these training aids)
