Mixed Group Validation (MGV) is an approach for estimating the diagnostic accuracy of tests. MGV is a promising alternative to the more commonly used Known Groups Validation (KGV) approach for estimating diagnostic accuracy. The advantage of MGV lies in the fact that the approach does not require a perfect external validity criterion or gold…

The Digit Span subtest from the Wechsler Scales is used to measure Freedom from Distractibility or Working Memory. Some published research suggests that Digit Span forward should be interpreted differently from Digit Span backward. The present study explored the dimensionality of the Wechsler Memory Scale-III Digit Span (forward and backward)…

Wechsler Memory Scale Memory Quotient (WMS MQ) 12 points below Wechsler Adult Intelligence Scale Full-Scale IQ (WAIS FSIQ) may indicate memory impairment. Investigated the relation of FSIQ to MQ when the Wechsler Adult Intelligence Scale-Revised rather than the WAIS is used. Discrepancy between FSIQ and MQ occurred less often with WAIS-R than with…

Wechsler Memory Scale-Revised (WMS-R) scores were analyzed for 82 epilepsy surgery candidates and used in combination with receiver operating characteristic curves to classify patients with left (LTL) and right (RTL) temporal lobe seizure onset. Results indicate that WMS-R scores used alone or in combination provide relatively poor discrimination…

Equations for prorating the Wechsler Memory Scale--Revised General Memory (GM) and Delayed Recall (DR) index scores were confirmed in a clinical sample of 258 patients. These prediction equations for the GM and DR summary scores have validity for patient samples similar to those of the present study. (SLD)

Attempts to validate the memory portion of the Strub-Black Mental Status Exam by comparing it to the Wechsler Memory Scale. Results indicate significant differences in almost all scores between the brain-damaged and normal groups. The Mental Status Examination appears valid for the differentiation of clinical samples and for the documentation of…

The Wechsler Memory Scale--Revised (D. Wechsler, 1987) and the Memory Assessment Scales (J. Williams, 1991) were administered to 30 head-injury patients, and results were compared across four dimensions of memory. Results suggest that these scales measure different abilities and are not comparable tests. (SLD)

Examined which memory dimensions deteriorate with increasing age and examines the construct validity of the Wechsler Memory Scale (WMS) (N=1,264 males and 1,141 females at six age intervals). Visual-spatial memory tasks, remembering stories, and learning pairs of associated words proved more difficult with advanced age. (JAC)

Using 308 patients referred for neuropsychological evaluation, 2 regression equations were developed to predict weighted raw score sums for General Memory and Delayed Recall using the Wechsler Memory Scale-Revised (WMS-R) analogs of 5 subtests from the original WMS. The equations may help reduce WMS-R administration time. (SLD)
