Gilliam Asperger's Disorder Scale (GADS)
by James E. Gilliam
The GADS is a norm-referenced assessment designed to evaluate individuals with unique behavior problems who may have Asperger's Disorder. Completed by a parent or professional--at school or at home--in just 5 to 10 minutes, the GADS is effective at discriminating persons with Asperger's Disorder from persons with autism and other behavioral disorders. Appropriate for individuals aged 3 to 22, the instrument provides the documentation about the essential behavior characteristics of Asperger's Disorder necessary for diagnosis.
The 32 clearly stated items describe specific, observable, and measurable behaviors and are divided into four subscales:
Additionally, an 8-item Parent Interview Form is provided to evaluate developmental delays.
Normed on 371 representative subjects with Asperger's Disorder, the GADS can also be used to monitor the effectiveness of special intervention programs, to target goals for IEPs, and for research purposes. |
