Author: Aaron Smith PhD SYNOPSIS A measure of concentration and decision making AGE RANGE 8 years to Adult ADMINISTRATION TIME Individual 5 minutes The Symbol Digit Modalities Test (SDMT) detects cognitive impairment in less than 5 minutes is simple, economical test is an ideal way for busy clinicians to screen for organic cerebral dysfunction in both children (8 years and older) and adults. Brief, easy to administer, and much less expensive than neuropsychological test batteries, the SDMT has demonstrated remarkable sensitivity in detecting not only the presence of brain damage, but also changes in cognitive functioning over time and in response to treatment. The SDMT involves a simple substitution task that normal children and adults can easily perform. Using a reference key, the examinee has 90 seconds to pair specific numbers with given geometric figures. Responses can be written or oral, and for either response mode, administration time is just 5 minutes. The WPS AutoScoreTM Test Form simplifies scoring. Individuals with cerebral dysfunction perform poorly on the SDMT, in spite of normal or above average intelligence. Examinees can give written or spoken responses and therefore the test can be used with almost anyone, including those with motor disabilities or speech disorders. As it involves only geometric figures and numbers, the SDMT is relatively culture free as well, and can be administered to people who do not speak English. The written form of the test lends itself to group administration and is therefore an economical way to screen apparently normal children and adults for possible motor, visual, learning, or other cerebral dysfunction. Unlike other symbol substitution tests, the SDMT also gives you the opportunity to compare written and spoken responses from the same individual. The manual provides separate norms for written and oral administrations of the test. Norms for children are also separated by sex and age, whereas those for adults are separated by age group and level of education. Like any single neuropsychological test, the SDMT is optimally used as part of a battery of instruments. It is highly effective as an initial screener, because it requires only 5 minutes yet detects cerebral dysfunction of almost any kind. Complete kit includes: manual and 25 WPS Autoscore Test Forms.
