Gilliam Autism Rating Scale (GARS-3)  Examiner's Manual-1583793

Gilliam Autism Rating Scale (GARS-3) Examiner's Manual

The GARS-3 is based on the definitions of autism adopted by the Autism Society of America and the Diagnostic and Statistical Manual of Mental Disorders: Fourth Edition-Text Revision (DSM-IV-TR). The instrument consists of 42 clearly stated items describing the characteristic behaviors of persons with autism. The items are grouped into three subscales: Stereotyped Behaviors, Communication, and Social Interaction. The validity of GARS- 3 was demonstrated by confirming that (a) the items of the subscales are representative of the characteristics of autism, (b) the subscales are strongly related to each other and to performance of other tests that screen for autism, and (c) the GARS-3 standard scores discriminate persons with autism from persons with other severe behavioral disorders, such as persons with mental retardation and multidisabilities.
