Which intelligence test is most commonly used for adults in clinical settings?

The Wechsler Adult Intelligence Scale (WAIS) is the most commonly used intelligence test for adults in clinical settings because it is specifically designed to assess adult intelligence and cognitive abilities. The WAIS has undergone several revisions since its inception, with the latest versions providing a comprehensive measure of various cognitive domains, such as verbal comprehension, perceptual reasoning, working memory, and processing speed. This broad assessment makes it highly applicable in clinical evaluations, allowing psychologists to identify cognitive strengths and weaknesses, diagnose potential disorders, and tailor interventions effectively.

The test's structure and standardized scoring enable reliable comparisons across diverse populations, reinforcing its widespread use in both clinical and research contexts. As a result, clinicians prefer the WAIS to assess adult individuals, which establishes it as a leading choice in intelligence testing for adults.
