Minnesota Multiphasic Personality Inventory T score conversion tables, 1957–1983.

Presents tables to facilitate the transformation of standard Minnesota Multiphasic Personality Inventory (MMPI) linear T score profiles to new MMPI normalized T score profiles (based on contemporary norms, as found by R. C. Collingan et al, 1983), and vice versa. These tables show that (1) the 1983 profiles are consistently less elevated than the corresponding 1957 profile presented by S. R. Hathaway and P. F. Briggs (see record 1959-01273-001) (if the latter are at or above T?=?50); (2) the more deviant a standard 1957 profile, the more this profile differs from its corresponding 1983 profile; and (3) the difference in elevation of 1983 and 1957 T scores for any fixed 1957 T score value varies across MMPI scales. Differences in elevations of 1957 and 1983 profiles of 20 or more T score points are possible when these profiles are generated from the same MMPI raw scores. Implications concerning false positive rates, false negative rates, and profile configurations are presented. (7 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
