Use of the Wechsler Memory Scale-Revised in traumatic brain injury.
The Wechsler Memory Scale-Revised (WMS-R) is a frequently used memory measure that has endured numerous criticisms, particularly related to the variability of results of factor analytic studies. The instrument relies on conglomerate Index scores to represent performance, in spite of tenuous empirical support. This study provides evidence that valuable information about memory abilities for individuals sustaining traumatic brain injury can be gained by investigating individual WMS-R subtest performance. The WMS-R was administered to a total of 54 subjects 36 individuals with moderate to severe TBI, and 18 normal controls. Results suggested that Index scores do not necessarily accurately represent performance on each of the individual Index subtests. Development of percentile scores for all subtests is strongly recommended, and implications for rehabilitation planning are discussed.
