indicators of suboptimal performance embedded in the Wechsler Memory Scale fourth edition wms iv
Journal of Clinical and Experimental Neuropsychology, 2016Co-Authors: Zita Bouman, Marc P. H. Hendriks, Roy P. C. Kessels, Ben Schmand, Albert P. AldenkampAbstract:ABSTRACTIntroduction. Recognition and visual working Memory tasks from the Wechsler Memory Scale–Fourth Edition (WMS–IV) have previously been documented as useful indicators for suboptimal performance. The present study examined the clinical utility of the Dutch version of the WMS–IV (WMS–IV–NL) for the identification of suboptimal performance using an analogue study design.Method. The patient group consisted of 59 mixed-etiology patients; the experimental malingerers were 50 healthy individuals who were asked to simulate cognitive impairment as a result of a traumatic brain injury; the last group consisted of 50 healthy controls who were instructed to put forth full effort.Results. Experimental malingerers performed significantly lower on all WMS–IV–NL tasks than did the patients and healthy controls. A binary logistic regression analysis was performed on the experimental malingerers and the patients. The first model contained the visual working Memory subtests (Spatial Addition and Symbol Span) and the ...

Clinical utility of the Wechsler Memory Scale - Fourth Edition (WMS-IV) in patients with intractable temporal lobe epilepsy
Epilepsy & behavior : E&B, 2016Co-Authors: Zita Bouman, Marc P. H. Hendriks, Roy P. C. Kessels, Didi Elhorst, Albert P. AldenkampAbstract:Abstract Introduction The Wechsler Memory Scale (WMS) is one of the most widely used test batteries to assess Memory functions in patients with brain dysfunctions of different etiologies. This study examined the clinical validation of the Dutch Wechsler Memory Scale — Fourth Edition (WMS-IV-NL) in patients with temporal lobe epilepsy (TLE). Method The sample consisted of 75 patients with intractable TLE, who were eligible for epilepsy surgery, and 77 demographically matched healthy controls. All participants were examined with the WMS-IV-NL. Results Patients with TLE performed significantly worse than healthy controls on all WMS-IV-NL indices and subtests (p Conclusion The WMS-IV-NL is capable of detecting Memory problems in patients with TLE, indicating that it is a sufficiently valid Memory battery. Furthermore, the findings support previous research showing that the WMS-IV has limited value in identifying material-specific Memory deficits in presurgical patients with TLE.

apparently abnormal Wechsler Memory Scale index score patterns in the normal population
Applied Neuropsychology, 2015Co-Authors: Roman Marcus Carrasco, Josefine Grups, Brittney Evans, Edward R Simco, Wiley MittenbergAbstract:Interpretation of the Wechsler Memory Scale-Fourth Edition may involve examination of multiple Memory index score contrasts and similar comparisons with Wechsler Adult Intelligence Scale-Fourth Edition ability indexes. Standardization sample data suggest that 15-point differences between any specific pair of index scores are relatively uncommon in normal individuals, but these base rates refer to a comparison between a single pair of indexes rather than multiple simultaneous comparisons among indexes. This study provides normative data for the occurrence of multiple index score differences calculated by using Monte Carlo simulations and validated against standardization data. Differences of 15 points between any two Memory indexes or between Memory and ability indexes occurred in 60% and 48% of the normative sample, respectively. Wechsler index score discrepancies are normally common and therefore not clinically meaningful when numerous such comparisons are made. Explicit prior interpretive hypotheses are necessary to reduce the number of index comparisons and associated false-positive conclusions. Monte Carlo simulation accurately predicts these false-positive rates.

identification of malingered head injury on the Wechsler Memory Scale revised
Psychological Assessment, 1993Co-Authors: Wiley Mittenberg, Richard L. Azrin, Cheryl L. Millsaps, Robert L. HeilbronnerAbstract:Thirty-nine head-injured outpatients were compared with 39 age-matched subjects who were instructed to malinger head trauma symptoms on the Wechsler Memory Scale-Revised (WMS-R) and Wechsler Adult Intelligence Scale-Revised. Head-injured patients were selected who were not involved in litigation or pursuing a Worker's Compensation claim. Groups did not differ significantly on IQs or Memory indexes. Discriminant function analyses based on the WMS-R subtests and indexes were able to accurately classify 91% and 83% of the cases, respectively. Decision rules were cross-validated on published data from several independent studies and statistically by means of the jackknife procedure. Head-injured patients appear to show a pattern of WMS-R scores that can be discriminated from the profile produced by individuals who attempt to malinger head trauma symptoms

Confirmatory factor analysis of the Wechsler Memory Scale-revised standardization sample
Archives of clinical neuropsychology : the official journal of the National Academy of Neuropsychologists, 1993Co-Authors: D. Bradley Burton, Wiley Mittenberg, Carol A. BurtonAbstract:Abstract A maximum likelihood confirmatory factor analysis was preformed by applying LISREL to the variance-covariance matrix obtained from standardization of the Wechsler Memory Scale-Revised (WMS-R) (N = 316). Analyses were designed to determine which of seven hypothesized factor solutions could best explain Memory function as measured by the WMS-R. Competing latent variable models were identified in previous exploratory and confirmatory factor analytic studies. The measurement error matrix was set to remove method variance shared by the immediate and delayed trials of the same subtest. Hypothesized factors were fixed and allowed to correlate. Results indicated that a three-factor model, including Attention/Concentration, Immediate and Delayed Memory, explained 91% of the score variance and produced a significantly better fit than the Attention/Concentration — General Memory or Attention Concentration — Visual/Verbal Memory solutions. Findings support previous work suggesting that the WMS-R measures separate Memory functions, and that the verbal/nonverbal Index distinction may not be a viable one.

Normative Data for the Wechsler Memory Scale—Revised: 25- to 34-Year Olds
Psychological Assessment, 1992Co-Authors: Wiley Mittenberg, Donald Bradley Burton, Evelyn Darrow, Garrie B. ThompsonAbstract:The normative data provided in the Wechsler Memory Scale-Revised (WMS-R) manual for individuals age 25 to 34 years were estimated statistically by interpolation. As an empirical check of this procedure, a representative stratified sample in this age range was selected to match the 1980 U.S. Census data on relevant demographic characteristics. Prorated Full Scale IQs for the group were normally distributed, having a mean of 101.3 (SD = 14.58, range = 72-131). Differences between the empirically derived and published index scores appeared to be clinically significant
