In several studies, suppressed Digit Span performance has been proposed as a potential marker for deliberately poor performance in a neuropsychological evaluation. The purpose of this study was to document Digit Span performance patterns in the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III; ) standardization sample and selected clinical groups. Base rate tables were generated for th...

The relationship between the Rorschach Prognostic Rating Scale (RPRS) and the Wechsler Adult Intelligence Scale (WAIS) was investigated to identify the factors, intelligence and others, which contribute to the RPRS. Correlation between the RPRS total and WAIS FSIQ showed that approximately 43% of the variance in the RPRS total can be accounted for by the variance in the FSIQ. Verbal IQ is not s...

Twenty-four studies utilizing the Wechsler Adult Intelligence Scale (WAIS) Digit Span subtest--either the Reliable Digit Span (RDS) or Age-Corrected Scaled Score (DS-ACSS) variant--for malingering detection were meta-analytically reviewed to evaluate their effectiveness in detecting malingered neurocognitive dysfunction. RDS and DS-ACSS effectively discriminated between honest responders and di...

Dimensional structures underlying the Wechsler Memory Scale-Fourth Edition (WMS-IV) and Wechsler Memory Scale-Third Edition (WMS-III) were compared to determine whether the revised measure has a more coherent and clinically relevant factor structure. Principal component analyses were conducted in normative samples reported in the respective technical manuals. Empirically supported procedures gu...
