Abstract
The Wechsler Memory Scale-Third Edition-Abbreviated (WMS-III-A) has been available for seven years and in that time there has been no research beyond the publisher’s normative study. This current research sought to show that the WMS-IIIA could be as effective as the full form Wechsler Memory Scale-Third Edition (WMS-III) in determining current functioning and also in detecting memory deterioration with premorbid measures like the Wechsler Test of Adult Reading (WTAR) and the Full Scale IQ predicted memory discrepancy method. This study used a sample size of 275 protocols from clients of a medicolegal practice using data from the WMS-III, the WAIS-III and WTAR as well as demographics necessary for analysis. This was used to transform the data into that from a WMS-III-A to compare predictive accuracy of performance to that of the WMS-III, and also sensitivity to detect accurately a decline in memory functioning using premorbid measures. Results found sufficient support for both similarity of scores of composites from WMS-III-A and indexes from WMS-III and also a high agreement rate on both measures using the WTAR and demographics (93.39%) and good accuracy with agreement with the Full Scale IQ predicted memory discrepancy scores (88.08%). This provides initial support for increased clinical application of the WMS-III-A. Further research would be warranted to be confident in results, though it may be useful with the new WMSIV and the possibility of developing a WMS-IV-A. Present research would suggest linking future versions of abbreviated WMS to include links to the WTAR and FSIQ predicted discrepancy for greater sensitivity in detecting memory impairment.
