Product Details

The Wechsler Adult Intelligence Scale®, Third Edition (WAIS®-III) is an advanced measure of cognitive ability for adults.

Benefits

  • WAIS–III scales have been co-normed with the WMS®–III to help you examine the important relationship between intellectual functioning and memory.
  • Administration time was reduced, and supplementary subtests were added to increase diagnostic utility.
  • WAIS–III has extended floors for most subtests, enhancing specificity in testing individuals who have lower cognitive functioning.

Features

  • Item content, artwork, and materials have been improved and updated. 
  • Extensive item bias analyses were performed to eliminate biased items.
  • Enlarged visual stimuli make the items easier for examinees with decreased visual acuity.

Validity, Clinical Studies

Validation studies include correlations between WAIS–III and WMS–III, WAIS–R, WISC–III,® WIAT,® Stanford Binet—Fourth Edition, and Raven's Progressive Matrices. WAIS–III (and WMS–III) clinical group studies included adults with clinical diagnoses of mental retardation, hearing impairments, reading disabilities, math disabilities, attention-deficit disorder, schizophrenia, closed-head injury, chronic alcoholism, Huntington's chorea, Korsakoff's syndrome, Parkinson's disease, and Alzheimer's disease.
