Wechsler Adult Intelligence Scale (WAIS)

The Wechsler Adult Intelligence Scale (WAIS) is an IQ test designed to measure intelligence and cognitive ability in adults and older adolescents. Most versions contain sub tests that represent the following components of intelligence: Verbal Comprehension Index (VCI), Perceptual Reasoning Index (PRI), Working Memory Index (WMI), Processing Speed Index (PSI). Two broad scores, which can be used to summarize general intellectual ability, can also be derived: 1) the Full Scale IQ (based on the total combined performance of the VCI, PRI, WMI, and the PSI) and 2) the General Ability Index (based only on the six subtests that the VCI and PRI comprise).

In TRAILS, the subtests block design, vocabulary, and digit span were used.
