Product Details

WASI-II gives psychologists, clinicians, and researchers a fast and reliable measure of intelligence when screening for intellectual disabilities or intellectual giftedness. WASI-II is also useful for reassessing individuals following a comprehensive evaluation. 

Benefits

  • Screen to determine if in-depth intellectual assessment is needed.
  • Reassess after a comprehensive evaluation.
  • Estimate a range of FSIQ scores on comprehensive batteries.
  • Assesses cognitive functioning of individuals referred for psychiatric evaluations.
  • Measure IQ scores for vocational, rehabilitation, or research purposes.
  • Compare results to the Wechsler Family Fundamentals: Academic Skills to determine a student’s academic strengths and needs based on an ability-achievement discrepancy analysis.

Features

The WASI-II builds on the strength of the WASI, providing updated versions of the WASI Vocabulary, Similarities, Block Design and Matrix Reasoning subtests. WASI-II also offers flexible administration options and strengthened connections with the WISC-IV and WAIS-IV.

  • Subtests are updated to provide a variety of improvements including shortened and streamlined instructions.
  • Four-subtest form can be administered in just 30 minutes; two-subtest form in about 15 minutes.
  • WASI-II subtests and items are revised to more closely parallel their counterparts in the WISC-IV and WAIS-IV.
  • Only six more subtests (rather than ten) need administering from the comprehensive measure to derive all WISC-IV or WAIS-IV composite scores.
  • Standardization of the WASI-II was conducted from January 2010 to May 2011 on a nationally representative sample of approximately 2,300 individuals aged 6–90.

FAQs

Frequently asked questions follow. Click on a question to see the response.

I like the WASI. How is the WASI–II different?

  • Updated normative sample: Norms are representative of today’s population and extend to 90:11.
  • Simplified administration and scoring
    • Shorter discontinue rules
    • Reversal rules are more user-friendly and more consistent with comprehensive Wechsler intelligence scales
    • Directions organized in a more streamlined fashion and reading instructions shortened by 40%
    • Stimulus Book enhancements improve user-friendliness:
      • Stimulus book now flips forward toward the examinee rather than backward toward you, making the pages easier to turn in situations where the testing surface is too wide.
      • Improved coil of the Stimulus Book makes pages easier to turn and binding more durable.
  • Closer parallels to WISC–IV and WAIS–IV:
    • Across the four subtests, 20-40% of the WASI–II items are new or revised.
    • Composite score names now reflect updated and consistent terminology with WISC–IV and WAIS–IV. For example:
      • VIQ (Verbal IQ) → VCI (Verbal Comprehension Index)
      • PIQ (Performance IQ) → PRI (Perceptual Reasoning Index)
  • Updated versions of WASI subtests
    • Similarities subtest floor (easy items) improved with new picture item type; as well as updates to items with close attention to vocabulary level of words and content that reflects abstract concepts and reasoning.
    • Matrix Reasoning subtest more similar to WISC–IV with realistic picture items.
    • Block Design subtest ceiling (hard items) stronger with new and innovative items.
    • Vocabulary subtest updated with new art as well as new ceiling items.

How can I maximize my use of the WASI–II with the WISC–IV and the WAIS–IV?

Because the WASI–II is linked to both the WISC–IV and the WAIS–IV, and provides unique items and subtests that also parallel the comprehensive measures, there are opportunities to maximize the clinical utility of these tests while saving you and your clients time.

The WASI–II can be used either before or after the comprehensive measures for situations in which multiple evaluations must be conducted. Because the items are unique to the WASI–II, practice effects are avoided.

The WASI–II can also be used as a screening measure to determine if comprehensive intellectual assessment with WISC–IV or the WAIS–IV is necessary. WASI–II subtest scores can be substituted for the corresponding WISC–IV or WAIS–IV subtest scores because the WASI–II subtests are statistically equated to the corresponding WISC–IV and WAIS–IV subtests. More specifically, the WASI–II subtest T scores can be converted to scaled score units and used in comprehensive FSIQ derivation.
