Technical information

• Normative data are based on a sample of 2,154 individuals ages 3-94 years from 32 states representative of 2012 U.S. Census statistics.
• Data were gathered from the following 12 clinical groups: stroke, dementia, hearing impaired, intellectual disability disorder (child and adult), TBI (child and adult), learning disabilities (child and adult), ADHD (child and adult), and gifted.
• Percentile ranks, 90% and 95% confidence intervals, T scores, z scores, NCEs, and stanines are available for index scores.
• Internal consistency studies associated with RIAS-2 indexes exceed .90 across age groups.
• RIAS-2 indexes correlated highly with RIAS indexes, providing support for the consistency of item content and performance between the original measure and this revision.
• Criterion-related validity was assessed by examining correlations between the RIAS-2 indexes and the WISC-IV, WAIS-IV, WPPSI-IV, AAB, FAR, and ChAMP. All correlations were found to be in the strong and as expected.

RIAS-2 Indexes

Why is the RIAS-2 a better test of intelligence due to fewer confounding factors?

Many intelligence tests introduce confounds in the form of construct irrelevant variance by including tasks that require fine-motor skills and that give bonus points for speed of performance on nonverbal intelligence tasks, and such speed is easily disrupted by attentional issues and ease of distractibility. Often such measures will also rely on academic tasks such as fund of information. RIAS-2 was constructed carefully to avoid as many such confounds as possible leading to a more direct measure of intelligence that is not clouded by fine motor issues, academic learning disabilities, or attentional and other noncognitive factors.

I am in private practice, why should I switch to the RIAS-2?

As managed care companies continue to cut and monitor hours for psychological and neuropsychological testing, time has become an increasingly valuable commodity. RIAS-2 provides a full assessment of intelligence in 30 minutes and also has conformed memory and processing speed tasks that add only 10-15 minutes. In contrast to most IQ measures, RIAS-2 saves you 45-60 minutes of testing and scoring time that can then be devoted to assessing other characteristics of your patient, allowing you to generate a more comprehensive, useful evaluation overall. Additionally, RIAS-2 record forms and protocols are less than half the cost per administration of those for competing measures and the detailed narrative report, which can be tailored to different fundamental referral questions, is also quick, easy to use, and less than half the cost of other common narrative reports. RIAS-2 thus saves on time and out of pocket expense and can improve your productivity as a clinician.

RIAS-2^TM

Reynolds Intellectual Assessment Scales^TM, Second Edition, Record Form with Spanish Responses

The RIAS-2 is an objective, reliable, and comprehensive test of intelligence and its major components. The RIAS-2 Record Form with Spanish Responses is a culturally fair assessment that allows bilingual and English language learners the option of answering items in Spanish.

Features and benefits

• Offers correct Spanish-answer options for the RIAS-2 Guess What, Verbal Reasoning, and What’s Missing subtests.
• Examinees can provide English or Spanish responses. Spanish dialects most commonly spoken in the U.S., including Mexican, Central American, Caribbean, Colonial Spanish, Puerto Rican, Cuban, Venezuelan, Columbian, and Argentinian, are included.
• Includes the new Language Acculturation Meter that provides a framework for interpreting test results by documenting years of education in Spanish and/or English, everyday language usage, and self-identified English comprehension.
• Aids in cognitive assessment of Spanish/English bilingual and English language learners.
• A new manual supplement describes the diligent translation process for the Spanish responses.

Test structure

• Includes two supplemental speeded processing subtests (one verbal, one nonverbal).
• All eight subtests can be completed in less than an hour.
• Includes reliable change scores and ability-achievement discrepancies with the Academic Achievement Battery (AAB).

Technical information

• Normative data (N = 2,154) represent 2012 U.S. Census statistics.
• Data were gathered from 12 clinical groups: stroke, dementia, hearing impaired, intellectual disability disorder (child and adult), TBI (child and adult), learning disabilities (child and adult), ADHD (child and adult), and gifted.

RIAS^TM-2 Remote

Reynolds Intellectual Assessment Scales^TM, Second Edition Remote

Since COVID changed the way you practice, you need options to continue serving your clients seamlessly and efficiently. PAR developed the RIAS-2 Remote to support your need for flexibility. The RIAS-2 components have been minimally modified and packaged digitally, and step-by-step videoconferencing instructions are included to allow you to continue assessing your clients for intelligence and its major components in remote settings.

An equivalency study (Wright, 2018*) between the RIAS-2 paper-and-pencil format and digital version produced positive results for all subtests except the supplemental speeded processing subtests—hence, they are excluded from the Remote.

One downloadable digital stimulus book is shared via videoconferencing with your student or client.

A white paper describes detailed administration procedures for the RIAS-2 and RIST-2 Remote. We recommend reviewing this resource prior to administration.
