Asperger Syndrome Diagnostic Scale

Diagnosing Asperger Syndrome is difficult because the characteristics of the disorder often resemble those of Autism, behavior disorders, ADHD, and some learning disabilities.

The ASDS examines specific behaviors to help you quickly assess the likelihood of Asperger Syndrome, document behavioral progress, target goals for change and intervention, and measure Asperger Syndrome for research purposes. The scale can be completed in approximately 15 minutes by anyone who knows the individual well.Back to the top How to Use the Assessment
All items included in the ASDS represent behaviors that are symptomatic of Asperger Syndrome and all are summed to produce the total score. The scores from the five subtests present the examiner with information of clinical interest regarding an individual's performance in comparison to that of others with Asperger Syndrome.

The total score has strong diagnostic value in identifying individuals with Asperger Syndrome and is the only score to be used when determining the likelihood of Asperger Syndrome. This contributes greatly to ease of administration and cuts down on otherwise time-consuming testing procedures. Back to the top
