The Asperger Syndrome Diagnostic Scale
(ASDS) is a quick, easy-to-use rating scale that can help you determine
whether a child has Asperger Syndrome. Anyone who knows the child or
youth well can complete this scale. Parents, teachers, siblings,
paraeducators, speechlanguage pathologists, psychologists,
psychiatrists, and other professionals can answer the 50 yes/no items in
10 to 15 minutes.
Designed to identify Asperger Syndrome in
children ages 5 through 18, this instrument provides an AS Quotient that
reveals the likelihood that an individual has Asperger Syndrome. The 50
items that constitute the ASDS were drawn from five specific areas of
behavior: cognitive, maladaptive, language, social, and sensorimotor.
Diagnosis of Asperger Syndrome is difficult because the characteristics
of the disorder often resemble those of autism, behavior disorders,
attention-deficit/hyperactivity disorder, and learning disabilities. The
ASDS serves an important function by quickly allowing you to determine
whether a child or adolescent is likely to have Asperger Syndrome.
The first test of its kind, the ASDS was normed on 115 persons with
Asperger Syndrome from across the United States. The sample ranged in
age from 5 to 18. The ASDS meets reliability and validity criteria
established by the professional assessment community. Therefore, by
comparing an individuals score with the normative sample, an examiner
can establish the probability that the individual has Asperger Syndrome.
Low AS Quotients are indicative of persons with little or no known
pathology, whereas higher scores are increasingly more indicative of
All items included in the ASDS represent
behaviors that are symptomatic of Asperger Syndrome, and all are summed
to produce the total score. The scores from the five subtests present
the examiner with information of clinical interest regarding an
individuals performance in comparison to that of others with Asperger
Syndrome. The total score has strong diagnostic value in identifying
individuals with Asperger Syndrome and is the only score to be used when
determining the likelihood of Asperger Syndrome. This contributes
greatly to ease of administration and cuts down on otherwise
time-consuming testing procedures.
The ASDS can be used with
confidence to (a) identify persons who have Asperger Syndrome, (b)
document behavioral progress as a consequence of special intervention
programs, (c) target goals for change and intervention on the student's
Individualized Education Program (IEP), and (d) measure Asperger
Syndrome for research purposes. Because the ASDS is based on
observations, the test results are valid only when the rater knows the
examinee well; that is, the examiner has had regular, sustained contact
with the examinee for at least 2 weeks.
Raw scores are
converted to percentile and standard scores. These scores are the most
important information associated with an individual's ASDS performance,
and analysis of them, augmented by additional test information, direct
information of behavior, and knowledge acquired from other sources, will
result in proper diagnosis of Asperger Syndrome.
