What is a Wechsler Abbreviated Scale of Intelligence (WAIS-IV)?

The WAIS-IV is a standardized, individually administered intelligence test to assess cognitive ability in adults ages 16 to 90. It is a revision of the Wechsler Adult Intelligence Scale–Third Edition (WAIS-III) and the fourth edition of the Wechsler Adult Intelligence Scale series.

The WAIS-IV is a comprehensive test that measures four broad areas of cognitive ability: verbal comprehension, perceptual reasoning, working memory, and processing speed. The test consists of 10 core and five supplemental subtests, which take approximately 60 to 90 minutes to complete.

What are the areas covered by WAIS-IV?

The WAIS-IV test measures various cognitive abilities and is used in multiple settings. The WAIS-IV can be a helpful tool for making different decisions, such as placement in educational programs, diagnosis of learning disabilities, and identification of cognitive impairment. Here is a more detailed description of the four broad areas of cognitive ability measured by the WAIS-IV:

  • Verbal comprehension‍: This measures the ability to understand and use language. Subtests that measure verbal comprehension include Similarities, Vocabulary, and Information.
  • Perceptual reasoning‍: This measures the ability to see and understand relationships between objects. Subtests that measure perceptual reasoning include Block Design, Matrix Reasoning, and Visual Puzzles.
  • Working memory‍: This measures the ability to remember information and use it to complete tasks. Subtests that measure working memory include Digit Span and Arithmetic.
  • Processing speed: This measures the ability to quickly and accurately process information. Subtests that measure processing speed include Symbol Search and Coding.

When to use the WAIS-IV IQ test?

While the WAIS-IV is a reliable and valid test of cognitive ability, it is essential to note that it is just one measure of intelligence. Other factors, such as education, experience, and motivation, can also affect a person's performance on the test. Here's when the WAIS-IV serves as a valuable tool for various purposes, including:

  1. Intellectual assessment: It is the most widely used intelligence test for adults. It assesses a person's overall cognitive ability and compares their performance to other adults of the same age.
  2. Clinical assessment: The WAIS-IV can assess a person's cognitive functioning in a clinical evaluation. It can also diagnose intellectual disabilities, learning disabilities, and other conditions that affect cognitive ability.
  3. Educational assessment: The WAIS-IV can be used to assess a person's cognitive abilities in the context of an educational evaluation. For example, the WAIS-IV can place students in appropriate academic programs or identify students needing special education services.
  4. Vocational assessment: It can assess a person's cognitive abilities in a vocational evaluation. For example, the WAIS-IV can determine a person's ability to learn new skills or perform job-related tasks.

Understanding the scoring system

The scoring system for the WAIS-IV can be a little confusing, so it's okay if you take your time to comprehend it. The scoring manual in your box set will explain it further. It assesses cognitive abilities through four core indexes: Verbal Comprehension (VCI), Working Memory (WMI), Perceptual Reasoning (PRI), and Processing Speed (PSI).

Verbal comprehension index scores

The VCI is a score derived from a selected range of psychometric properties subtests. It measures an individual's verbal comprehension of knowledge and reasoning. VCI scores include the scores from the following three subtests: similarities, vocabulary, and information.

Working memory index scores

This index reflects an individual's ability to take in information and hold it in their working memory. The active memory index focuses on keeping that information in mind while performing a task classed as a mental operation (Greenwood, n.d.). WMI scores include the scores from the following two subtests: digit span sequencing and arithmetic,

Perceptual reasoning index scores

This index focuses mainly on organization with visual information an individual has received. Within this index, the individual is tested on their nonverbal skills that require more visual puzzles to engage in what they comprehend (Greenwood, n.d.). PRI scores include the scores from the following three subtests: block design, matrix reasoning, and visual puzzles.

Processing speed index scores

This index is precisely what you might be thinking it is. This index focuses on the speed at which an individual can process visual information. PSI scores include the score from the following two subtests: symbol search and coding.

WAIS-IV Record Form example (sample)

The WAIS-IV Record Form is a two-section document used to record the results of the Wechsler Adult Intelligence Scale, Fourth Edition. The form includes information about the examinee, such as their name, age, date of birth, and education level. It also includes space to record the examinee's scores on each of the 10 subtests of the WAIS-IV. The form also provides space to record the examinee's Full Scale IQ (FSIQ), Verbal IQ (VIQ), and Performance IQ (PIQ).

How is the test scored?

The WAIS-IV is scored on a scale of 45 to 155, with a mean of 100 and a standard deviation of 15. The test consists of 10 core subtests and five supplemental subtests. The core subtests calculate four composite scores: Verbal Comprehension, Perceptual Reasoning, Working Memory, and Processing Speed. The supplemental subtests can supplement the composite scores or provide additional information about the test taker's cognitive abilities.

The raw scores for each subtest are converted to scaled scores with a mean of 10 and a standard deviation of 3. The scaled scores are then converted to standard scores, with a mean of 100 and a standard deviation of 15. The composite scores are calculated by averaging the scaled scores for the subtests that make up the composite.

Here are some additional details about how the WAIS-IV is scored:

  • Raw scores: The raw score for each subtest is the number of items the test taker answered correctly.
  • Scaled scores: Scaled scores are converted from raw scores using a table provided in the WAIS-IV manual. Scaled scores have a mean of 10 and a standard deviation of 3.
  • Standard scores: Standard scores are converted from scaled scores using a table provided in the WAIS-IV manual. Standard scores have a mean of 100 and a standard deviation of 15.
  • Composite scores: Composite scores are calculated by averaging the scaled scores for the subtests that make up the composite. The four composite scores on the WAIS-IV are Verbal Comprehension, Perceptual Reasoning, Working Memory, and Processing Speed.

The WAIS-IV is a complex test, and the scoring process can be challenging. However, following the steps outlined above and using a WAIS-IV Scoring template ensures the test is scored accurately.
