Effects of Canadianization of American-biased items on the WAIS and WAIS-R information subtests.

Abstract
Eight items on the information subtest of the WAIS [Wechsler Adult Intelligence Scale] have a distinct American content bias. Four of these were retained on the WAIS-R [Wechsler Adult Intelligence Scale-Revised]. Data from studies involving a Canadianized version of the information subtest are reported. Canadianization significantly alters the item difficulty of 2 items but not the remaining 6. Thus, since Canadianization has minor or negligible effects on the psychometric qualities of the test, it should be Canadianized for Canadian exmainees.
