Validation of an item-reduction short form of the Stanford-Binet Intelligence Scale: Fourth Edition with college...

This study investigated the comparability of item-reduction and subtest-reduction short forms of the Stanford-Binet Intelligence Scale: Fourth Edition (SB:IV) with the complete battery in a sample of college students. All item-reduction SASs were not significantly different from the full battery SASs. Correlations for corresponding SASs and subtests between the complete and short form were highly significant, and analyses of the short-form profile supported the interpretation of individual subtests. The subtest-reduction short-form SASs were significantly lower than both the item-reduction short form and the full battery. Thus, an item-reduction short form proved to be a more comparable estimate of the full battery composite than the subtest-reduction short form.
