Use One Convenient Form to Score Any ADI-R Algorithm
Typically, administration and scoring require from 1½ to 2½ hours.
Results can now be scored and interpreted using a single convenient form rather than the five forms previously required. The Comprehensive Algorithm Form (W-382E) allows you to calculate and interpret any one of five age-specific ADI-R algorithms (two Diagnostic Algorithms based on developmental history and used for formal diagnosis, and three Current Behavior Algorithms focusing on present functioning and used for treatment and educational planning). The algorithms themselves have not changed; the revised form simply replaces the five forms previously needed to calculate the algorithms.

Support Diagnosis or Determine Clinical Needs
Because the ADI-R is an interview rather than a test, and because it focuses on behaviors that are rare in unaffected individuals, it provides categorical results rather than scales or norms. Results can 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.


The ADI-R DVD Training Package consists of eight DVDs (with a total running time of 16 hours), an accompanying Guidebook, nine Interview Booklets, and three Comprehensive Algorithm Forms. The DVDs allow you to observe expert interviewers as they administer the ADI-R to parents. The Guidebook discusses each case featured on the DVDs, clarifying coding and scoring decisions. (NOTE: Study of the DVDs and Guidebook is required. While the DVDs may be viewed by multiple professionals, each trainee must individually review the Guidebook and complete the Interview Booklets and Algorithm Forms.)

When you have finished the DVD Training Package, you can receive 18 continuing education credits by purchasing and successfully completing the ADI-R Continuing Education (CE) Questionnaire and Evaluation Form (W-382CE).
If you plan to use the ADI-R in formal research, you may require additional training provided by the test authors and their colleagues. Contact WPS Customer Service for information about training for research applications.

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 (W-382A) and enter responses into the program for rapid results.
