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…

Relative to other cognitive areas, there are few clinical measures currently available to assess social perception. A new standardized measure, the Wechsler Advanced Clinical Solutions (ACS) Social Perception subtest, addresses some limitations of existing measures; however, little is known about this new test. The first goal of this investigation…

The authors review the "Advanced Clinical Solutions for WAIS-IV and WMS-IV". The "Advanced Clinical Solutions (ACS) for the Wechsler Adult Intelligence Scale-Fourth Edition" (WAIS-IV; Wechsler, 2008) and the "Wechsler Memory Scale-Fourth Edition" (WMS-IV; Wechsler, 2009) was published by Pearson in 2009. It is a…

This study assessed trait validity of the Reynolds Intellectual Assessment Scales' (RIAS) Verbal Index (VIX) and Nonverbal Index (NIX) scores in a group of college students. Using both observation of patterns and latent variable modeling of a multitrait-multimethod correlation/covariance matrix, the results indicate that the RIAS VIX scores…

Indicated excellent cross-validations with correlation of 0.99 for past formulas (J. L. Woodard and B. N. Axelrod, 1995; B. N. Axelrod et al, 1996) for estimating the Wechsler Memory Scale- Revised General Memory and Delayed Recall Indexes. Over 85% of the estimated scores were within 10 points of actual scores. Age, education, diagnosis, and IQ…

Visual constructive and visual-motor skills in the deaf population were investigated by comparing performance of deaf native signers (n = 20) to that of hearing nonsigners (n = 20) on the Beery-Buktenica Developmental Test of Visual-Motor Integration, Rey-Osterrieth Complex Figure Test, Wechsler Memory Scale Visual Reproduction subtest, and…

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)

Increasingly neuropsychologists are under pressure, particularly in child custody and personal injury litigation, to justify the validity of the tests upon which their assessments are based. Reviews research on the validity of clinical opinions based on tests and concludes that test scores must be used in conjunction with life history and current…

Normative data for the Wechsler Memory Scale-Revised were derived empirically using a sample of 50 volunteers between 25 and 34 years of age, who matched U.S. Census data on demographic characteristics. Differences between these empirical norms and published norms that were estimated statistically appear clinically significant. (SLD)

Research on the standardization, reliability, validity, factor structure, and subtests of the Wechsler Memory Scale (WMS) (1945) and its revised version (1987) is reviewed. Much research relating to the WMS appears to be relevant to the revised version. Use of the instrument in Australia is discussed. (SLD)
