ADI-R Set of Interview Booklets and Comprehensive Algorithm Forms for Training
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 caregiver 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.
Key Features
Composed of 93 items, the ADI-R focuses on three functional domains:
- Language / Communication
- Reciprocal Social Interactions
- Restricted, Repetitive and Stereotyped Behaviours and Interests
Sample Reports
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 Video-Based Training
Administration and coding of the ADI-R are highly standardized, and valid assessment requires training. The ADI-R Training Video Program (LMS-382) allows clinicians to learn administration procedures and to practice accurate coding. Associated continuing education (CE) credits are also available. This program is now available in an online self-study format on the WPS Professional Learning Center (WPS ProLearn); it was previously offered only as a DVD training package. If clinicians plan to use the ADI-R in formal research, they may require additional training provided by the test authors and their colleagues. PAA is not involved in these courses.
The ADI-R Training Video Program (LMS-382) consists of online videos (with a total running time of 16 hours) that show expert interviewers as they administer the ADI-R to parents. Digital support materials for use with the online videos include a Training Guidebook that discusses each case featured on the videos and that clarifies coding and scoring decisions. The following print materials, sold separately, are also needed: the ADI-R Interview Booklet (W-382A) and the ADI-R Comprehensive Algorithm Form (W-382E). For convenience, a combined set of these printed forms for use with the program materials is available (W-382H).
To purchase the ADI-R Training Video Program (LMS-382) on the (WPS ProLearn), simply add the products to your cart and complete your purchase. You will receive a follow-up email from PAA and WPS with information on how to access the materials on the (WPS ProLearn).
Use one convenient form to score any ADI-R algorithm
Typically, administration and scoring require from 1.5 to 2.5 hours. Results can now be scored and interpreted using a single convenient form rather than the five forms previously required. The new Comprehensive Algorithm Form (Product Code W-382E) allows you to calculate and interpret any one of five, age-specific ADI-R algorithms (two Diagnostic Algorithms based on developmental history are used for formal diagnosis and three Current Behaviour Algorithms focusing on present functioning are used for treatment and educational planning). The algorithms themselves have not changed; the new form simply replaces the five forms previously needed to calculate all algorithms.
Support diagnosis or determine clinical needs
Because the ADI-R is an interview rather than a test, and because it focuses on behaviours that are rare in non affected individuals, it provides categorical results rather than scales or norms. Results may be used to support a diagnosis of autism or to determine the clinical needs of various groups in which a high rate of autism spectrum disorders might be expected (e.g., individuals with severe language impairments or certain medical conditions, children with congenital blindness, and youngsters suffering from institutional deprivation).
The ADI-R has proven very effective in differentiating autism from other developmental disorders and in assessing syndrome boundaries, identifying new subgroups and quantifying autistic symptomatology. Extensive use of the ADI-R in the international research community has provided strong evidence of the reliability and validity of its categorical results.
Scoring CD: System Requirements
The ADI-R unlimited-use CD allows you to score all ADI-R algorithms. Compatible with Windows XP, Vista or Windows 7, 8 and 10. CD ROM drive and USB port required. Use the standard paper-and-pencil administration (Product Code W-382A) and enter responses into the program for rapid results.
