| Abstract: | To determine the impact of the Minnesota Multiphasic Personality Inventory—2 (MMPI-2; J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989) on the Megargee offender classification system, 1,213 male offenders' responses on the original Minnesota Multiphasic Personality Inventory (MMPI) were rescored and reprofiled as MMPI-2s, and the MMPI-2s of 422 male prisoners were used to estimate their original MMPIs. When classifications based on the original MMPIs were compared with those from MMPI-2s, less than two thirds were classified identically. Therefore, the original Megargee rules should not be used to classify MMPI-2s. A new set of classifactory rules was devised for the MMPI-2 which, on cross-validation, agreed with the original MMPI classifications in 82% of the cases.
