Summary

    About This Product

    BY CECIL R. REYNOLDS, PHD, AND RANDY W. KAMPHAUS, PHD

    Features and Benefits

    • Assesses both verbal intelligence (problem solving and reasoning using acquired knowledge and skills) and nonverbal intelligence (reasoning and spatial ability using novel situations and stimuli)
    • Offers optional verbal and nonverbal memory subtests that yield the Composite Memory Index
    • Yields a highly reliable General Reasoning Index that reflects overall reasoning and problem-solving skills
    • Provides the highly reliable General Reasoning Index reflecting general reasoning and problem-solving skills
    • Informs diagnosis of specific disorders such as intellectual disabilities and is useful in educational placement

    What’s New in the Second Edition

    • New speeded processing subtests (verbal and nonverbal) combine to create the Speeded Processing Index
    • Improved data for superior interpretation
    • Revised, consistent basal and ceiling rules allow more accurate assessment at the lowest and highest ability level
    • Updated item content to eliminate confusing and outdated content
    • Wider range of T-scores—at least 25 to 75 for most grade levels

    Technical Information

    • Data collected 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
    • Available scores include percentile ranks, 90% and 95% confidence intervals, T scores, z scores, NCEs, and stanines
    • Internal consistency studies associated with RIAS-2 indexes exceed .90 across age groups
    • High correlation between the RIAS and RIAS-2 Indexes shows the consistency of item content and performance between the two measures
    • 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 to very strong range.
    • Strong to very strong correlations between the RIAS-2 and other measures, including the AAB, FAR, and ChAMP demonstrate the criterion-related validity of the RIAS-2
