Autism Diagnostic Interview-Revised (ADI-R)
About the ADI-R
by Michael Rutter, M.D., FRS, Ann LeCouteur, M.B.B.S., and Catherine Lord, Ph.D.
The Autism Diagnostic Interview-Revised (ADI-R, 2003, Western Psychological Services), used for decades in research, is a comprehensive interview that provides an in-depth assessment for individuals suspected of having autism or other autism spectrum disorders. The ADI-R is a standardized, semi-structured clinical interview composed of 93 items which focuses on three functional domains: language and communication, reciprocal social interactions, and restricted, repetitive and stereotyped behaviors and interests. The ADI-R administers to parents or caregivers of those with Autism Spectrum Disorders and can be used to assess individuals throughout their life span beginning with children aged 2 years throughout adulthood. Following highly standardized procedures, the interviewer records and codes the informants responses paying particular attention to the behavioral descriptions offered. Results are scored and interpreted using algorithms which yield diagnoses of either autism spectrum disorder or non-spectrum. Because the ADI-R is an interview rather than a test, and because it focuses on behaviors not commonly seen in non-affected individuals, it provides categorical results rather than scales or norms. The ADI-R has been shown to be highly effective in differentiating autism from other developmental disorders, and is useful for formal diagnoses as well as treatment and educational planning. Results can be used to support a diagnosis of autism or to determine the clinical needs of individuals with Autism Spectrum Disorders.
- 2.5-Day ADI-R Clinical Trainings
- 2.5-Day ADI-R Research Trainings
Using a combination of lecture, live demonstration and large group scoring discussions, participants will be introduced to the measure. Participants will then receive direct “hands on” instruction and individualized supervision as they each begin to apply knowledge learned by administering themselves portions of the ADI-R with live volunteers.
Over the course of this training, attendees will:
- Learn the differences between respondent-based interviews and investigator-based interview methods.
- Observe a standardized administration of the interview.
- Be introduced to the standardized administration procedures involved in recording and coding informant responses.
- Learn to complete the interview protocols, and calculate diagnoses from completed algorithm
- Take part in scoring discussions which are (1) designed to enhance their understanding of the standardized scoring procedures and (2) intended to facilitate accurate coding of informant responses.
- Understand how the ADI-R can assist in the diagnosis of Autism & other Pervasive Developmental Disorders.
- Administer and score sections of the interview themselves to parent volunteers of children affected with ASD.
- Receive individualized supervision and feedback of their administration.
- Discuss the usefulness of the results in the context of the comprehensive Autism assessment and for determining differential diagnosis.
- Understand the procedures involved in achieving reliablity on the measure.
ADI-R DVD training packages are available through WPS and are especially useful as a supplemental aide for those seeking to learn more or achieve greater competence. As always, those who intend to use the ADI-R in research must attend in-person training for all three days of training.
