Read the full product description

Used in research for decades, this comprehensive interview 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 administer the ADI-R, an experienced clinical interviewer questions a parent or carer 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.

Evaluate 3 functional domains:

Composed of 93 items, the ADI-R focuses on three functional domains:

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

Following highly standardised 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 milestones
  • Language acquisition and loss of language or other skills
  • Current functioning in regard to language and communication
  • Social development and play
  • Interests and behaviours
  • Clinically relevant behaviours, such as aggression, self-injury and possible epileptic features.

Master the ADI-R with DVD training

Interviewers can refer to the ADI-R DVD Training Package, described on the next page, to learn accurate coding procedures. It is recommended that users study the training materials before administering the ADI-R. The total running time for the ADI-R DVDs is 2 hours and 46 minutes.

Score All ADI-R Algorithms With an Unlimited-Use CD

The ADI-R unlimited-use CD allows you to score all ADI-R algorithms. Use the standard paper-and-pencil administration and enter responses into the program for rapid results.
