Content & Administration
The WASI–II builds on the strength of the WASI by providing updated versions of the WASI Vocabulary, Similarities, Block Design and Matrix Reasoning subtests, flexible administration options (i.e., four- or two-subtest versions), and strengthened connections with the WISC–IV and WAIS–IV.
(Vocabulary, Similarities, Block Design, Matrix Reasoning) provides:
- FSIQ–4 score: Estimate of general cognitive ability
- VCI score: Measure of crystallised abilities
- PRI score: Measure of nonverbal fluid abilities and visual motor/coordination skills
(Vocabulary and Matrix Reasoning) provides:
- FSIQ–2 score: Estimate of general cognitive ability
Strengthened Connections with the WISC–IV and WAIS–IV
The strengthened connections between the WASI–II and the comprehensive Wechsler intelligence scales result in a stronger empirical foundation for using the instruments together, and offer practical benefits that help you save time. The WASI–II subtests and items have been revised to more closely parallel their counterparts in the WISC–IV and WAIS–IV. Linking studies have been conducted with the WAIS–IV and the WISC–IV to establish equivalency and to improve comparability with the comprehensive Wechsler scales’ composite scores. Taken together, these improvements enhance the joint use of the WASI–II and the comprehensive scales.
If after screening, the WASI–II results indicate comprehensive intellectual assessment is needed, the WASI–II subtest scores can be substituted for the four corresponding subtest scores on the WISC–IV or WAIS–IV, which makes re-administration of those four subtests from the WISC–IV and WAIS–IV unnecessary.
- Updated norms: The standardisation of the WASI–II was conducted from January 2010 to May 2011 on a sample of approximately 2,300individuals aged 6–90.
- Improved floors and ceilings
- Linking studies with the WISC–IV and the WAIS–IV to:
Provide prediction intervals from WASI–II FSIQ to the comprehensive FSIQ;
Provide supporting data and guidelines for substituting WASI–II subtests for parallel subtests in the comprehensive scales.
Use in Australia and New Zealand
The Australian and New Zealand office of Pearson Clinical Assessment has been involved in the development and pilot phases of the WASI-II since 2008. As a result of this involvement the language and cultural differences of Australia and New Zealand have, where possible, been taken into consideration in the WASI-II. The WASI-II standardisation was undertaken in the U.S.
WASI-II and WAIS-IV Australian and New Zealand Language Adapted Edition
The WAIS-IV Australian and New Zealand Language Adapted Edition and the WASI-II both use U.S. norms. WASI-II Substitution can therefore be undertaken with the WAIS-IV in accordance with the procedures set out in the WASI-II Administration and Scoring Manual and the Technical Report.
WASI-II and WISC-IV Australian Standardisation Edition
The WISC-IV Australian Standardisation Edition (WISC-IV Australian) uses Australian norms while the WASI-II uses U.S. norms. Supplementary analysis suggested that the limited use of U.S. WASI-II norms within the WISC-IV Australian is likely to have a negligible impact on test scores, please refer to the Technical Note below for full details. WASI-II Substitution can therefore be undertaken with the WISC-IV Australian in accordance with the procedures set out in the WASI-II Administration and Scoring Manual and the Technical Report provided below.
