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.
 
Composed of 93 items, the ADI-R focuses on three functional domains:
  • Language/Communication
  • Reciprocal Social Interactions
  • Restricted, Repetitive, and Stereotyped Behaviors 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 behavior
  • 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 behaviors
  • Clinically relevant behaviors, such as aggression, self-injury, and possible epileptic features
 
Use one convenient form to score any ADI-R algorithm Results can now be scored and interpreted using a single convenient form rather than the five forms previously required. The new Comprehensive Algorithm Form 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 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 behaviors that are rare in nonaffected 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.
 
ADI–R DVD Training Package
Interviewers can refer to the ADI-R DVD Training Package 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.
