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. The RIAS provides a practical measurement device in terms of efficacies of time, direct costs, and information needed from a measure of intelligence. (Reynolds and Kamphaus, 2003).

MeSH If you want to measure g through Gf and Gc with a very efficient, thoroughly validated instrument, you want the RIAS. The study confirmed Frey and Dettermans equation, (2) best predicted IQ from recentered SAT scores. Two verbal subtests (Guess What and Verbal Reasoning) comprise the Verbal Intelligence Index, and are designed to assess crystalized intelligence. If you are trying to assess thinking, reasoning, and problem-solving ability, you do not want to use intelligence tests that require a blind child to copy block designs or a child with an oral language disorder to define words. e-mail: sdombrowski@rider.edu The research Implications from this study are much the same, as those stated by Frey and Detterman, namely, that SAT appears to be a measure of general intelligence, and is a useful tool in predicting cognitive functioning.

The RIAS Composite Index score was significantly higher than the WAIS-III Full Scale IQ, although scores on both tests were in the average range. The results were mixed, with some findings supporting the validity of the Composite Intelligence Index (CIX), Nonverbal Intelligence Index (NIX), and Verbal Intelligence Index (VIX) while others suggested that the CIX and NIX in particular should be interpreted with caution, depending on the population in which the RIAS is being used.

The RIAS is administered individually by experts, adjusting the difficulty by the age of the individual being examined. However, the RIAS may provide higher scores for children who have significant psychomotor problems or specific problems with working memory or processing speed (underlying psychological processing deficits oft times associated with SLD children.)
