What is the reliability of the WAIS-IV test?
The reliability and validity of the WAIS-IV is outlined in the Technical and Interpretive Manual [1]). The main reliability figure based on the standardisation sample for Full Scale IQ was 0.98, indicating good internal consistency.
Is the WAIS R test reliable?
The median retest reliability coefficient for the WAIS-R subtests was . 71. These data indicate that IQ scores are reliable in older normal individuals for this retest interval, but less confidence can be placed in the reliability of subtest scores and the Verbal-Performance Discrepancy.
What does the WAIS test measure?
The Wechsler Adult Intelligence Scale (WAIS) is an intelligence test first published in 1955 and designed to measure intelligence in adults and older adolescents.
What is a criticism of the WAIS?
What is a criticism of the WAIS? Giving people an overall IQ score gives the impression that there is only one kind of intelligence. You just studied 20 terms!
What is the reliability of the WISC V?
Psychometric Data Reliability (internal consistency) of the WISC-V FSIQ and Primary Index scores is generally high, with average coefficients for all ages ranging from 0.84 (PSI) to 0.97 (FSIQ). Reliability for the Ancillary Index scores is also high, ranging from 0.91 (AVMI) to 0.97 (GAI).
What does the VCI measure on the WAIS?
The Verbal Comprehension Index (VCI) is a score derived from the administration of selected subtests from the third and fourth edition Wechsler Adult Intelligence Scale (WAIS) and Wechsler Intelligence Scale for Children (WISC). The VCI is designed to provide a measure of verbal acquired knowledge and verbal reasoning.
What are the core subtests of WAIS IV?
The Performance subtests were: Picture Arrangement, Picture Completion, Block Design, Object Assembly, and Digit Symbol. A verbal IQ, performance IQ and full scale IQ were obtained.
What is the WISC test used for?
The Wechsler Intelligence Scale for Children – Fifth Edition, Australian Standard (WISC-V) is an individually administered and comprehensive clinical instrument used to assess the general thinking and reasoning skills of children aged six years to 16 years.
What types of skills do the WAIS-IV subtests measure?
The WAIS-IV comprises a full scale IQ, as well as indexes on four factors: verbal comprehension, perceptual reasoning, working memory and processing speed.
What is an advantage of how the WAIS-IV is administered?
A strength of the WAIS-IV is inclusion in the test manual of numerous validity studies with clinical samples. An advantage of the WAIS-IV over previous Wechsler adult scales is easier administration because of fewer concrete materials to manipulate.
