Subscore added value analyses assume invariance across test taking populations; however, this assumption may be untenable in practice as differential subdomain relationships may be present among subgroups. The purpose of this simulation study was to understand the conditions associated with subscore added value noninvariance when manipulating: (1)…

The findings of research on short forms of the Wechsler Adult Intelligence Scales-Revised are used to illustrate points about three criteria for evaluating the usefulness of a short form. Results indicate there is little justification for regarding the three criteria as criteria. (Author/BL)

Correlations were obtained between scores on the full form of the MSCA and the Kaufman, Taylor, and McCarthy Screening Test short forms. (Author/LMO)
