Reynolds Intellectual Screening Test, 2nd Ed (RIST-2)

Description

The RIST-2 is a brief screening measure helps you quickly identify individuals who need a more comprehensive intellectual assessment. Derived from the updated RIAS-2 subtests, the RIST-2 retains the same two subtests as the original RIST: Guess What, a verbal subtest, which is a traditional measure of crystallized intelligence; and Odd-Item Out, a nonverbal subtest, which focuses on fluid intelligence.

The RIST-2 normative sample is the same as that for the RIAS-2, which was updated to reflect the most recent U.S. Census. Criterion-related validity was assessed via correlations with the WISC-IV™ FSIQ (.68), WAIS-IV™ FSIQ (.62), WPPSI-IV™ FSIQ (.62), AAB Composite (.53), FAR Total Index (.40), and ChAMP Total Memory Index (.51).

Score correlations strongly suggest the RIST-2 is an appropriate screener for intelligence. Validity of the RIST-2 was assessed in studies with stroke, dementia, hearing impairment, traumatic brain injury, intellectual disability disorder, ADHD, learning disability, and gifted clinical groups.

The RIST-2 can effectively identify individuals with an intellectual impairment. Correlations between the RIST-2 index and RIAS-2 subtests were .84 and .87, respectively, for Guess What and Odd-Item Out.
