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 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.
Evaluate 3 functional domains
Composed of 93 items, the ADI-R focuses on three functional domains:
- 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 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.
