The purpose of the current study was to assess the validity of the Reynolds Intellectual Assessment Scale's (RIAS) index and subtest scores by examining whether the RIAS conforms to Carroll's ( 1993 ) three-stratum theory of cognitive ability and the Cattell-Horn Gf-Gc (Horn & Cattell, 1966 ) theory of intelligence upon which it was based. 17, Iss. The functioning of the two nonverbal subtests in all analyses suggested that the RIAS's nonverbal subtests are most problematic, with the greatest impact on the RIAS's validity as a measure of overall, verbal, and nonverbal intelligence. The RIAS intellectual scales are comprised of 4 subtests. 15. A Comparison of Low IQ Scores From the Reynolds Intellectual Assessment Scales and the Wechsler Adult Intelligence Scale Third Edition Thomas B. Umphress Abstract Twenty The RIAS intelligence subtests include Verbal Reasoning (verbal), Guess What (verbal), Odd-Item Out (nonverbal), and What's Missing? Two nonverbal subtests (Odd Item Out and What's Missing) comprise the Nonverbal Intelligence Index and are considered measures of fluid intelligence.

The Reynolds Intellectual Assessment Scales, Second Edition (RIAS-2; Reynolds & Kamphaus, 2015) is an intelligence test for those aged 3 to 94 years. [1] It is appropriate for individuals ages 394. A comprehensive and cost-effective intelligence test, the RIAS is a high-quality, reliable instrument that provides the necessary information to help clinicians make decisions regarding classification, selection, and educational placement. For reliability, the minimal standard for using a score in making a high stakes decision has always been regarded as being .90 or above.

To obtain clinical normative data, the RIAS was administered to 507 individuals representing 15 different clinical groups within the following categories: organic syndromes, mental retardation, learning disability, ADHD, and psychiatric disorders. In validating the inferences of the test results, it is important to consider the consequences of the tests interpretation and use. Two verbal subtests (Guess What and Verbal Reasoning) comprise the Verbal Intelligence Index, and are designed to assess crystalized intelligence. and validity cannot exceed reliability, and reliability is NOT determined by the number of subtests in a composite score.

The RIAS can be used, for example, as a comprehensive measure of verbal and nonverbal intelligence and of global intelligence; as a measure of memory of meaningful verbal material and visual memory; and for the purposes of diagnosis of various childhood disorders (e.g., learning disabilities, mental retardation, and giftedness).

Back in the day, (when dinosaurs roamed the earth) when other widely used tests were basing their scores on five or (for the overall composite or IQ score) 10 or more subtests, this was widely regarded as a weakness. However, the IDEA has never (ever) required high stakes decisions to be based on tests with a specific number of subtests. Since the induction of the originalStanford-Binet scalesin 1916, intelligence tests have faced the challenges of excessive length and a dependence on motor coordination and reading skills, which encumbers the test and advantages those with superior skills in certain fields. 2008 Jun;46(3):229-33. doi: 10.1352/2008.46:229-233. ), Reported correlations between CIX and WIAT Composites ranged from .60 to .69.

Two additional optional tests assessing short term memory can also be converted and summed as above to generate a Composite Memory Index. These T-scores are then summed and converted to generate Verbal and Nonverbal Index T-scores. The RIAS is at the forefront of the next. The original RIASs reliablity and validity scores, based on two or four subtests, were equal to those achieved by tests that were much longer (sometimes more than twice as long) in length. There was a significant difference between the RIAS Nonverbal Intelligence and WAIS-III Performance Scale, but there was no significant difference between the RIAS Verbal Intelligence Index and the WAIS-III Verbal Scale IQ.

The original RIASs reliablity and validity scores, based on two or four subtests, were equal to those achieved by tests that were much longer (sometimes more than twice as long) in length. Test users are always responsible for checking the technical manuals that come with their tests to insure that those standards have been met.

Verbal Intelligence Index, Nonverbal Intelligence Index, Composite Intelligence Index, and an optional Composite Memory Index. A t test showed that the RIAS Composite Intelligence Index scores were significantly higher than WAIS-III Full Scale IQ scores at the alpha level of .01. Indeed, one limited (N=34) study of referred children tested using the WISC IV and the RIAS confirmed that trend. A t test showed that the RIAS Composite Intelligence Index scores were significantly higher than WAIS-III Full Scale IQ scores at the alpha level of .01. The RIAS-2 also encompasses a two-subtest abbreviated intelligence test called the Reynolds Intellectual Screening Test, Second Edition (RIST-2). Editors Note: Except for the CIX (overall score, composed of four subtests), all of the Index scores on the RIAS Second Edition are composed of two subtests. CIX reliability is reported to be about .97; the reliability for the FSIQ on the WISC IV was reported to be about .98; reliability for GAI on the WISC IV was reported to be .96. Jared D.

Objective: The Reynolds Intellectual Assessment Scales (RIAS) is a measure of intelligence that provides estimates of verbal and nonverbal intelligence, and verbal and nonverbal memory. In his study, Edwards (2006) found a correlation of .86 between CIX and FSIQ on the WISC IV, despite differences between the mean scores. Little is known about the psychometric properties of the RIAS memory scales. Clin Neuropsychol. Comparing performance (or percentile ranks) on the Verbal intelligence Index (VIX) and Nonverbal Intelligence Index (NIX) may help examiners distinguish between these two types of intelligence.
