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. Reynolds RIAS and RIAS-2 Tests What is the RIAS? The RIAS should be well received in the United States because of its sound psychometric properties, clinical and empirical utility, ease of administration, scoring, and interpretation, nondependence on motor coordination, visual-motor speed, and reading. 17, Iss.

Standards for Educational and Psychological Testing. 8600 Rockville Pike The RIAS allows for continuity of measurement across all developmental levels from ages 3 through 94 years for both clinical and research purposes. VIX and NIX T-scores are summed and converted to a Composite Intelligence (CIX). The RIAS (based on a study of 54 children) correlated .76 with FSIQ on the old WISC III. 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. In this regard, the RIAS is a restricted purchase product, and proof of training is required for its purchase. For 8 to 10 year olds. IQ 135) and American Mensa (min.

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.) Implications from this study are much the same 2003) is an individually administered test of intelligence for use with individuals Verbal, alone, best predicted IQ as measured by the RIAS. Two new speeded processing subtests (one verbal, one nonverbal) that require minimal reliance on motor skills. 3. 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.

The RIAS can satisfy that need and should become part of every school psychologists, battery of tests. Administration of the four intelligence subtests takes approximately 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. It contains eight subtests designed to assess general intelligence, verbal and nonverbal intelligence, memory, and processing speed. The RIAS substantially lessens the time to assess intelligence without compromising statistical integrity. (Elliott, 2004). The Reynolds Intellectual Screening Test RIST-2 is useful in clinical and school practice when a global estimate of intelligence is all that is needed. The most frequent criticism levied at the RIAS is that in the best of all possible worlds, there would be more studies of predictive validity than were included in the test manual. The RIST-2 can typically be administered in about 12 min. The Reynolds Intellectual Assessment Scales (RIAS; Reynolds & Kamphaus, 2003) is an individually administered test of intelligence for use with individuals, between the ages of 3 and 94. Cecil R.

FOIA sharing sensitive information, make sure youre on a federal 1. For reliability, the minimal standard for using a score in making a high stakes decision has always been regarded as being .90 or above. Crystal intelligence is an individuals ability to gain knowledge through experiences, such as education and verbal memorization. While the Cattell Model measures these two features, the RIAS abbreviates the exam process and adds a memory index section. 2003 May;17(2):273-84. doi: 10.1076/clin.17.2.273.16499.

New normative data and updated item content. The RIAS measures intelligence through its two sub-sections of Crystal Intelligence, and Fluid Intelligence. The results raise questions concerning test selection for diagnosing intellectual disability and the use of the correlation statistic for comparing intelligence tests. Careers. Of course (by law) no decision should ever be made based on a single assessment. You want an intelligence measure that is not contaminated by the documented weaknesses, even or especially if those weaknesses are in abilities important to intellectual functioning., Since the RIAS eliminates many of those potentially contaminating factors up front, however, the amount of analysis required to determine the tasks appropriateness is clearly reduced.

The RIAS substantially lessens the time to assess intelligence without compromising statistical integrity. (Elliott, 2004). The Reynolds Intellectual Screening Test RIST-2 is useful in clinical and school practice when a global estimate of intelligence is all that is needed. The most frequent criticism levied at the RIAS is that in the best of all possible worlds, there would be more studies of predictive validity than were included in the test manual.
