Asperger's Disorder Detail
The scales described below can help identify a variety of symptoms affecting children and adolescents. Do not assume that a particular "score" on any rating scale or screening tool means a child has a particular disorder-these instruments are only one component of an evaluation. Diagnoses should be made only by a trained clinician after a thorough assessment. Symptoms suggestive of suicidal or harmful behaviors warrant immediate attention by a trained clinician.

Gilliam Asperger's Disorder Scale (GADS)
Clinician

A behavioral rating scale of 32 items that identifies and helps diagnose individuals ages 3-22 with Asperger's Syndrome. GADS includes 4 core subscales (Social Interaction, Restricted Patterns of Behavior, Cognitive Patterns, and Pragmatic Skills) and an optional subscale (Early Development) to be completed by parents. The optional subscale consists of eight questions. GADS takes 10 minutes to complete.

Childhood Asperger Syndrome Test (CAST)
Parent Clinician

This 38-item yes/no screening measure, designed for parents to answer about their children ages 4-11, is based on the core features of the autism spectrum disorder. If parents suspect an autism spectrum disorder, they can complete this test, and take it to their primary care provider.

Asperger Syndrome Diagnostic Scale (ASDS)
Clinician

This 50-item scale is designed to identify children and adolescents ages 5-18 who exhibit characteristics of Asperger's Syndrome. Included are symptoms in maladaptions, socialization, language, cognition, sensory development, and motor development. The ASDS is for use by clinicians to: identify those persons who have Asperger's Syndrome, document behavioral progress as a consequence of special intervention programs, target goals for change on the Individualized Education Programs (IEP), and help in research.

The ASDS takes 10-15 minutes to complete and can be purchased at:

Krug Asperger's Disorder Index (KADI)
Clinician

A highly sensitive test to identify individuals ages 6-22 with Asperger's Syndrome. It correctly detects most people with the condition, but may also incorrectly identify people who do not actually have Asperger's. The 32 items are individually administered and enable professionals to distinguish individuals with Asperger's Syndrome from individuals with other forms of high functioning autism. KADI takes 15-20 minutes to administer. Information associated with the KADI can be used to help assess a student's educational needs.

Clinician

Developed by Tony Attwood, PhD, this 25-item questionnaire is designed to identify behaviors and abilities indicative of Asperger's Syndrome in school children ages 6-12.

It takes 5-10 minutes to complete and is available at:
