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: Social Interaction Restricted Patterns of Behavior Cognitive Patterns Pragmatic Skills      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.
