Abstract: PURPOSE - The Gilliam Asperger's scale is designed to evaluate behavioral problems in children with Asperger's syndrome. GENERAL DESCRIPTION - The Gilliam Asperger's Disorder Scale (GADS) is a 40 item measure consisting of 4 subscales and an additional optional scale to identify developmental delays. The test can be used to establish a diagnosis of Asperger's syndrome, identify behavior problems associated with it, to establish goals for treatment and to monitor progress. Items in the ADS were developed from the DSM-IV. TARGET POPULATION - The test is meant for children and young adults in the age group 3-22 years. ADMINISTRATION - Typically, the test requires about 5-10 minutes to complete and has to be administered individually. In some cases interviews can take about 25 minutes. SCORES - Scores are available for 4 subscales, Social Interaction, Restricted Patterns of Behavior, Cognitive Patterns, Pragmatic Skills. Raw scores have to be converted to standard scores. The Asperger's Disorder Quotient (ADQ) is a final score derived from all the four subscales and is an indicator of the likelihood that a person has AD. MANUAL - Available, published in 2001. RELIABILITY AND VALIDITY - The sample for standardization of the test was obtained from the United States (92%), Canada, Mexico, Great Britain and Australia. Test-retest reliability for a small sample of 10 persons, tested after a two week interval ranged from .71 to .77 for the subscales and .93 for the total scale. Criterion validity was established by comparing it with the Gillian autism Scale. (CIRRIE Abstract) (Please check the appropriate Mental Measurements Yearbook for a more detailed review)
