Description


The ADI–R helps you accurately assess individuals suspected of having Autism or an Autism Spectrum Disorder. Results can support diagnostic decisions, assist in differentiating Autism from other disorders, and provide an empirically validated basis for education and treatment planning. The ADI–R has proven particularly effective in assessing syndrome boundaries, identifying new subgroups, quantifying Autistic symptomatology, and determining the clinical needs of groups in which a high rate of Autism Spectrum Disorders might be expected, such as people with severe language impairments.

How to Use the Assessment
To administer the ADI–R, an experienced clinical interviewer questions a parent or caretaker who is familiar with the developmental history and current behavior of the individual being evaluated, and uses standardized procedures to code the responses. The interview can be used to assess children and adults as long as their mental ages are two years or higher. Because the ADI–R is an interview rather than a test, and because it focuses on behaviors that are rare in non-affected individuals, it provides categorical results rather than scales or norms.
