Interscorer agreement was examined by comparing two independent scorers of all WAIS-IV standardization record forms. Agreement ranged from .98–.99.
Short-term test-retest stability was investigated for 298 individuals from four age groups with retest intervals ranging from 8–82 days
Stability coefficients were highest for the FSIQ and VCI followed by the PRI, WMI, and PSI scores, and generally lower for the subtests as found in other intelligence tests.
“Practice effects” greatest for PRI subtests (Block Design, Visual Puzzles, Figure Weights, and Picture Completion)
Administration and scoring of the WAIS require an active test administrator who must interact with the test taker and must know test protocol and specifications. WAIS administrators must receive proper training and be aware of all test guidelines.

Internal consistency estimates produced by Spearman-Brown corrected split-half or coefficient alpha methods are presented for each of the 13 age groups. Internal consistency estimates across all 13 age groups ranged from .97–.98 for the FSIQ; from .87–.98 for the factor index scores (VCI, PRI, WMI, PSI); and from .71–.96 for the subtests.
Intelligence & General Aptitude
Wechsler believed that intelligence was complex, and made up a number of different mental abilities rather than a single general intelligence factor.
Which 3 of these pieces go together to make this puzzle?
Wechsler
Adult Intelligence Scale
•Digit span: attention, concentration, mental
control
(e.g., Repeat the numbers 1-2-3 in reverse sequence)
•Arithmetic: Concentration while manipulating mental mathematical problems
(e.g., "How many 45-cent stamps can you buy for a dollar?")
•Letter-Number Sequencing [Supplemental]:
attention and working memory
(e.g., Repeat the sequence Q-1-B-3-J-2, but place the
numbers in numerical order and then the letters
in alphabetical order)
Which one of these goes here to balance the scale?
•Symbol Search: Visual
perception, speed
•Coding: Visual-motor coordination, motor and mental speed
•Cancellation [Supplemental]: visual-perceptual speed
The standardization sample (N = 2,200) was obtained using stratified proportional sampling across variables of age, sex, race/ethnicity, education level (or parent education level for ages 16–19), and geographic region.
Mostly positive
However, there are a number of minor issues
Validity estimates were
reported based on:
(factor structure)
(convergent and divergent/
discriminant comparisons)
The Full Scale IQ (FSIQ), General Ability Index (GAI), and Index scores
(M = 100, SD = 15) were generated by summing subtest scaled scores and normalized with composite score distributions visually smoothed to eliminate irregularities.
and consistency
“The aggregate or global capacity of the individual to act purposefully, to think rationally, and to deal effectively with his environment”
Older adolescents and adults age 16-90
Verbal Comprehension Index (VCI)
Perceptual Reasoning Index (PRI)
Working Memory Index (WMI)
The Processing Speed Index (PSI)
More efficient administration time
Simplified technical manual organization
Added teaching items to ensure understanding of task
Reduced vocabulary-level for
verbatim instructions
Strengths
One of the best measures of general intellectual functioning available. It assesses four important dimensions of cognitive ability, including Verbal, Perceptual, Working Memory, and Processing Speed. Research shows that each of these four dimensions is a strong correlate of learning, school achievement, and cognitive development.
