The KADI enables professionals to accurately distinguish individuals with Asperger's disorder from individuals with other forms of high functioning autism. This very difficult diagnostic decision is made easier with the KADI. Once the Individualized Education Plan (IEP) team is aware that the person may have Asperger's disorder, a more appropriate IEP can be written. Information associated with the KADI can be used to help assess a student's educational needs. The KADI is also a prescreening scale that immediately identifies individuals who do not have Asperger's disorder.

Validity of the KADI

Validity studies on the KADI included content-descriptive validity, criterion-predictive validity, and construct-identification validity. The manual provides evidence that the KADI was developed with a high degree of validity across all three types of validity and that the test user can have confidence in the diagnostic discriminating power of the KADI.

Reliability of the KADI

Tests of reliability on the KADI included content sampling, time sampling, and interscorer differences. The manual provides evidence that the KADI produces a high degree of reliability across all three types of reliability and that the test user can have high confidence in the results.

Standardization

In all, the study sample included 486 individuals with a sample of 130 individuals with a previous diagnosis of Asperger's disorder. A sample of 162 individuals previously diagnosed with high functioning autism, and a control sample of 194 normal individuals. Surveys were collected from over 30 states and ten countries.

Weighted Scores

Each item on the KADI has a weighted score which was determined by statistical analysis of the items predictive ability to differentiate Asperger's disorder from high functioning autism and the normal population.
