Objectives: The aim of this study was to compare Minnesota Multiphasic Personality Inventory (MMPI) linear T-scores and MMPI-2 uniform T-scores in a Turkish Sample. Materials and Methods: The study included 50 adult (30 female and 20 male) volunteers that completed MMPI and MMPI-2. Age of the participants ranged from 18 to 55 years (mean: 24.96 Sd 8.66). The tests were administered at least 3 weeks apart. MMPI linear T-score, MMPI-2 uniform T-score, and MMPI-2 linear T-score were compared via 3 x 2 repeated-measures ANOVA. Results: There wasn't a significant difference between the mean MMPI subscales' scores and MMPI-2 subscales' scores. Change in the number of items and content did not result in significant difference; however, minimal differences were thought to be due to the method used to compute the T-scores. Additionally, MMPI-2 hypochondriasis, depression, and hysteria subscale scores differed between males and females. Discussion: These findings support earlier reports of the psychometric equivalence of the original MMPI and MMPI-2. Additionally, there weren't any profile differences between the 2 tests; therefore, the findings support the idea knowledge of old profiles can be used in new ones. Nonetheless, during the transition from MMPI to MMPI-2, it may be helpful to remain aware of the differences in some subscales for females.
