Peer reviewed Peer reviewed
Direct linkDirect link
Holdnack, James A.; Zhou, Xiaobin; Larrabee, Glenn J.; Millis, Scott R.; Salthouse, Timothy A. – Assessment, 2011
The Wechsler Adult Intelligence Scale-fourth edition (WAIS-IV) and the Wechsler Memory Scale-fourth edition (WMS-IV) were co-developed to be used individually or as a combined battery of tests. The independent factor structure of each of the tests has been identified; however, the combined factor structure has yet to be determined. Confirmatory…

Orthogonal Higher Order Structure and Confirmatory Factor Analysis of the French Wechsler Adult Intelligence Scale (WAIS-III)
Peer reviewed Peer reviewed
Direct linkDirect link
Golay, Philippe; Lecerf, Thierry – Psychological Assessment, 2011
According to the most widely accepted Cattell-Horn-Carroll (CHC) model of intelligence measurement, each subtest score of the Wechsler Intelligence Scale for Adults (3rd ed.; WAIS-III) should reflect both 1st- and 2nd-order factors (i.e., 4 or 5 broad abilities and 1 general factor). To disentangle the contribution of each factor, we applied a…

Wechsler Memory Scale: A Selective Review of the Literature.
Peer reviewed Peer reviewed
Prigatano, George P. – Journal of Clinical Psychology, 1978
Research on the Wechsler Memory Scale (WMS) is reviewed, including the relationship of Memory Quotient to Full Scale IQ. Despite its limitations, WMS has been a sensitive test of short-term memory, which may be helpful in identifying dominant (left) temporal lobe impairment. (Author/SJL)

A Normative Study of the Wechsler Memory Scale
Peer reviewed Peer reviewed
Kear-Colwell, J. J.; Heller, Mary – Journal of Clinical Psychology, 1978
Aims of this study were to determine whether the factor structure produced in earlier research by Kear-Colwell (1973, 1977) on the Wechsler Memory Scale could be replicated in a non-patient population (most research uses patient populations) and also to examine the effects of age, sex, and social class on the performance of normal adults on this…

The Effects of Age and Sex on the Factor Structure of the Wechsler Memory Scale.
Peer reviewed Peer reviewed
Arbit, Jack; Zagar, Robert – Journal of Psychology, 1979
Reveals a two-factor structure (general retentiveness and memory) in the Wechsler Memory Scale for total male and female samples and for both males and females aged 13 to 39 years and 40 to 59 years but not for males or females aged 60 to 88 years. (Author/RL)

Construct Validity of WAIS-R Factors: Neuropsychological Test Correlates in Adults Referred for Evaluation of Possible Head Injury.
Peer reviewed Peer reviewed
Sherman, Elisabeth M. S.; And Others – Psychological Assessment, 1995
A 3-factor solution of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) in 260 adults with suspected head injury suggested relatively good construct validity for the factors, based on correlations with neuropsychological tests. Findings are discussed in terms of the multidimensional nature of neuropsychological tests and WAIS-R factors.…

Mayo's Older Americans Normative Studies (MOANS): Factor Structure of a Core Battery.
Peer reviewed Peer reviewed
Smith, Glenn E.; And Others – Psychological Assessment, 1992
Using the Mayo Older Americans Normative Studies (MOANS) group (526 55-to 97-year-old adults), factor models were examined for the Wechsler Adult Intelligence Scale-Revised (WAIS-R); the Wechsler Memory Scale (WMS); and a core battery of the WAIS-R, the WMS, and the Rey Auditory-Verbal Learning Test.
