(2009) An Exploratory Investigation of the Factor Structure of the Reynolds Intellectual Assessment Scales (RIAS). The RIAS uses a median score of 100 with a standard deviation of 15, like most intelligence exams. . This article describes the goals for development of the RIAS and its underlying theory, emphasizing its applicability to the identification of intellectually gifted individuals. Studies reported in the Manual suggest that children with learning and/or attention disorders tend to perform lower on tasks that measure working memory and processing speed., (Frequently Asked Questions, Harcourt Brace website). Items are presented from a stimulus book or verbally and testees provide a brief verbal response or a point to indicate their response. The authors reviewed the RIAS-2 and concluded that is a high-quality intelligence test. Rider University For reliability, the minimal standard for using a score in making a high stakes decision has always been regarded as being .90 or above. Bethesda, MD 20894, Web Policies 2016;5(2):156-60. doi: 10.1080/21622965.2015.1015337. Contact our Customer Support Department at 1.800.331.8378. Does the test do what it is supposed to do?

Administration of the four intelligence subtests takes approximately Twenty people with suspected intellectual disability took the Reynolds Intellectual Assessment Scales (RIAS; C. R. Reynolds & R. W. Kamphaus, 1998) and the Wechsler Adult Intelligence 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. Test validation is an on going process, not a finished task once the first technical manual is issued. All normative data were collected in Spain. The RIAS-2 includes a two-subtest Verbal Intelligence Index (VIX), a two-subtest Nonverbal Intelligence Index (NIX), and a Composite Intelligence Index (CIX), created by combining the VIX and NIX scores. government site.

The RIAS allows for continuity of measurement across all developmental levels from ages 3 through 94 years for both clinical and research purposes. (Reynolds and Kamphaus, 2003). MeSH determination of eligibility for special education and program needs, but to do so at a lower cost and in a 62 0 obj <>stream Wechsler Intelligence Scale for Children-V: Test Review. 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. These T-scores are then summed and converted to generate Verbal and Nonverbal Index T-scores. 2003) is an individually administered test of intelligence for use with individuals The following is the least authoritative of the reviews posted above. Factor structures of RIAS scores from typically developing (n = 187) and mixed clinical groups (n = 164), 4-18 years old, were compared using confirmatory factor analysis. 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.) and transmitted securely. Compared to similar measures, the RIAS-2 is faster: all eight subtests can be completed in less than an hour; the screening measure (the RIST-2) provides a g score in less than 15 minutes. The RIAS (based on a study of 54 children) correlated .76 with FSIQ on the old WISC III. The new version of the RIAS will be ready for use from mid-2016, (Reynolds & Kamphaus, n.d). Received 9 August 2005; accepted 16 January 2006 Third Edition 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. sharing sensitive information, make sure youre on a federal 8600 Rockville Pike Federal government websites often end in .gov or .mil. 2009 May;12(6):551-62. doi: 10.1177/1087054708322996. Test users are always responsible for checking the technical manuals that come with their tests to insure that those standards have been met. Nonetheless, future research is needed with a wider, range of IQ instruments to assess which SAT variables are the best predictors, and what weight each should. Overall, comparable scores for the general population would be expected. University of Alberta, Canada. Standards for Educational and Psychological Testing. 1999. 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. (Reynolds and Kamphaus, 2003). Would you like email updates of new search results? The test was designed to provide a unitary and valid assessment of g and components fluid and crystalized intelligence (based on Horn and Cattell model of intelligence). It measures this through questions on verbal, and non-verbal memory. Please enable JavaScript on your browser. The RIAS should be administered by examiners who have formal training in assessment. This internal memorandum was submitted to the Exceptional Children Director to demonstrate that the RIAS was fully compliant with federal regulations requiring that all evaluations be both reliable and valid for the purpose for which they were being used. While the RIAS is not always the best test to use in all circumstances, it proved its worth in the vast majority of both initial and re-evaluations. Reynolds made a further adaptation in the Reynolds Intellectual Screening Test, which can be administered in 10 minutes to quickly screen large amounts of students to determine if any require a full examination in order to determine special or gifted education. 2455 Teller Road, Thousand Oaks, CA 91320. range of IQ instruments to assess which SAT variables are the best predictors, and what weight each should The children tested had a RIAS CIX that was on average about 8 to 9 points higher than the FSIQ; but when GAIs were calculated, that difference fell to three to four points. The RIAS II has many practical uses. (A child will not score the same on a Woodcock Johnson Tests of Achievement that he would on the End of Grade test; some children will score higher, some lower.).

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. 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. The legal (and ethical) standard has always been to use tests that have been validated for the purpose for which they are being used . intelligence for school districts that are under serious pressure to provide measures of intelligence for RIAS: It is the least authoritative of the articles in this section, but it was written in response to concerns by teachers that (because of the brief testing time) he was substituting a screening test for a real intellectual assessment. The two subtests targeting processing speed are new to the RIAS-2. government site. The RIAS can satisfy that need and should become part of every school psychologists, battery of tests. government site. in the Reynolds Intellectual Assessment Scales (RIAS). Nevertheless, additional research in clinical settings is needed. 2012 Mar;24(1):129-40. doi: 10.1037/a0024878. and validity cannot exceed reliability, and reliability is NOT determined by the number of subtests in a composite score. Martin Mrazik This study sought to assess the ability of the equations Frey and Detterman (2004) presented to assess IQ, in the Reynolds Intellectual Assessment Scales (RIAS). 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. As a rule of thumb, any score two standard deviations above the median RIAS and intellectual giftedness (Click for paper), Abstract: Strengths of the RIAS are in the normative sample, short administration time, the addition of a Cecil R. Reynolds, PhD, and Randy W. Kamphaus, PhD, Measures verbal and nonverbal intelligence and memory, 30-35 minutes for both the full Intelligence and full Memory assessments; 20-25 minutes to obtain CIX; 10 minutes for the Memory assessment, Behavior Rating Inventory of Executive Function. 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.
