Wechsler Adult Intelligence Scale | Fourth Edition
WAIS–IV
David Wechsler, PhD
The Wechsler Adult Intelligence Scale | Fourth Edition (WAIS-IV) is the most advanced adult measure of cognitive ability, based on recent research in the area of cognitive neuroscience and the theories and work of David Wechsler PhD.
- Publication date: 2008
- Age range: Individuals 16:0-90:11
- Scores/interpretation: FSIQ, Index scores, subtest level scaled scores
- Qualification level: C
- Completion time: 60-90 minutes for core subtests
- Administration: Paper-and-pencil or digital
- Scoring options: Q-interactive® Administration and Scoring, Q-global® Scoring & Reporting, Manual scoring
WAIS-IV was developed to provide the most advanced measure of cognitive ability and results when addressing the changing clinical landscape.
Benefits
- Reflects changing demographics, emerging clinical needs, new research, and increased caseloads.
- Expanded clinical utility.
- Increased developmental appropriateness.
- Enhanced user-friendliness.
- Improved psychometric properties.
- Updated structural foundations.
Features
A core battery of 10 unique subtests focuses on four specific domains of intelligence: verbal comprehension, perceptual reasoning, working memory, and processing speed.
- New subtests, including Visual Puzzles, Figure Weights, and Cancellation.
- Additional tasks for improved clinical utility, new clinical and validity studies.
- Transitioned from dual IQ to Index Score structure.
- Improved measures of Working Memory, Processing Speed, and Fluid Reasoning.
- Improved floors/ceilings, improved subtest/composite reliability, and expanded FSIQ range.
- Enhanced user friendliness and reduced administration time (by 15%).
- Co-normed with the Wechsler Memory Scale®-IV.
- Updated normative data for ages 16-90 years and enhanced utility for older adults.
Visual Puzzles
Contributes to Perceptual Reasoning Composite, more reliable measure than Object Assembly, requires no motor skills.
Figure Weights
Contributes to Perceptual Reasoning Composite, measure of quantitative and analogical reasoning, requires no motor skills.
Cancellation
Contributes to Processing Speed Composite, imbedded Stroop Effect, provides scores.
