Screening Tools for Asperger's Syndrome
There are two instruments
publicly available for screening individuals with Asperger's Syndrome.
The first, developed by Dr. Tony Attwood, is the Australian
Scale for Asperger's Syndrome. This instrument, as of yet, does
not provide a quantitative score. It is, however, undergoing a revision
by Dr. Attwood to this end. It is intended for children of primary
school age (grades K through 8).
The second instrument
is the Childhood
Asperger Syndrome Test (CAST), developed by Dr. Simon Baron-Cohen
at Cambridge University in the United Kingdom. A cut-off score of
15 was considered to successfully predict Asperger's Syndrome in
50 percent of 1925 children rated. The CAST can be completed by
parents and/or teachers.
An important caveat:
Screening instruments are not tests or diagnostic instruments. They
are used to guide and inform individuals as to the potential risk
for Asperger's Syndrome. If in doubt, follow through with a formal
diagnostic process with healthcare professionals expert in the area
of autism spectrum disorders.
