WAIS-IV UPDATE

We want to bring to your attention a change we have made to the WAIS–IV Technical and Interpretive Manual, Table C.2: Differences Between the FSIQ and the GAI Required for Statistical Significance. The formula previously used to calculate these values did not account for the subtests that are common to both composite scores. The attached table serves as the replacement for Table C.2. This change does not affect the calculation of an examinee’s subtest or composite scores.

In recognition of emerging demographic and clinical trends, the Wechsler Adult Intelligence Scale®–Fourth Edition (WAIS–IV®) was developed to provide you with the most advanced measure of cognitive ability and results you can trust. The WAIS-IV offers precision and simplicity in one comprehensive battery combined with the enhanced utility that results from the rigorous collection and stratification of normative data
that is the hallmark of Wechsler tradition.

It is this commitment to excellence that led us to focus on four issues to guide the WAIS-IV revision:

• Changing demographics

• Shifting clinical needs

• Emerging research

• Increasing caseload 

Australia and New Zealand Language Adaptation

To maintain high levels of validity and reliability, and to ensure the most effective use in Australia and New Zealand, the WAIS-IV has been language adapted for our populations.

Test Structure

The WAIS–IV structure was modified to align with the widely popular WISC–IV® and to reflect current theory regarding cognitive ability.

The new structure is also more reflective of current cognitive ability theory and divides scores into four specific domains. The core battery consists of ten total subtests that yield the FSIQ and four Index Scores. There are also five supplemental subtests that may be substituted for core subtests or administered for additional information.

New Subtest Samples

Visual Puzzles Contributes to Perceptual Reasoning Composite More reliable measure than Object Assembly Requires no motor skills Q: "Which 3 of these pieces go together to make this puzzle?" A: "Options 1, 3 and 6 go together to make this puzzle."
Figure Weights   Contributes to Perceptual Reasoning Composite Measure of quantitative and analogical reasoning Requires no motor skills Q: "Which one of these goes here to balance the scale?" A: "Option 2 goes there to balance the scale."
Cancellation Contributes to Processing Speed Composite Imbedded Stroop Effect Provides scores for omission and commission errors   "When I say go, draw a line through each red square and yellow triangle."
