Reynolds Intellectual Assessment Test-2

Excl. Tax: £396.11 Incl. Tax: £475.33

Product Code: RIAS-2

Please note: VAT is added at checkout.

Features and benefits
Can be used as a stand-alone intellectual assessment or as part of a larger battery to diagnose specific disorders, such as intellectual disabilities or learning disabilities, and as a way to determine educational placement.
All four core and two memory subtests from the original RIAS were retained; however, individual harder and easier items were added to provide greater range, and other items were revised to allow fo rmore up-to-date and acceptable responses.
All new for the RIAS-2: Two supplemental speeded processing subtests (one verbal, one nonverbal) combine to create the Speeded Processing Index (SPI).
Requires low motor demand.
Optional memory and speeded processing subtests are available.
By popular demand, all basal and ceiling rules for the subtests are more conservative, are consistent with one another, and allow for more accurate assessment at the lowest and highest ability level.
Ability–achievement discrepancies with the Academic Achievement Battery (AAB) are provided. A combination kit is available.
Technical information
Normative data are based on a sample of 2,154 individuals ages 3-94 years from 32 states, representing 2012 U.S. Census proportions for age, gender, geographic region, ethnicity, and years of education.
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.
