Efficiency of Local versus Standard MMPI Norms: A Comment

Abstract

This note shows that evidence considered by Wooten (1984) to support claims of diagnostic superiority of standard over local MMPI norms, may mainly reflect the fact that a large proportion of the group tested by Wooten's consisted of persons with emotional, behavioral problems. Reevaluation of Wooten's data suggests a range of conditions under which Wooten's diagnostic criterion used with local norms is superior to the same criterion used with standard norms, and another range of conditions under which this criterion used with either local or standard norms is inferior to base rates.
