Ys. Benporath et A. Tellegen, HOW (NOT) TO EVALUATE THE COMPARABILITY OF MMPI AND MMPI-2 PROFILE CONFIGURATIONS - A REPLY TO HUMPHREY AND DAHLSTROM, Journal of personality assessment, 65(1), 1995, pp. 52-58
Humphrey and Dahlstrom (1995) presented a study on the comparability o
f MMPI/MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989)
profiles in which they concluded that ''the bases for clinical interpr
etation derived from the MMPI and MMPI-2 profiles were sufficiently at
variance to require different conclusions'' [sic] (p. 2). In this bri
ef critique, we identify procedural and data-analytical deficiencies t
hat invalidate Humphrey and Dahlstrom's argument. Their blanket recomm
endation based on this argument, namely, that clinicians routinely plo
t both MMPI and MMPI-2 profiles, is unwarranted.
