A comparison of MMPI-2 and MMPI T-scores for men and women

The original MMPI linear T-score norms are compared with the new linear and uniform T-score norms for the MMPI-2 across basic validity and clinical scales for both men and women. The comparison indicated more pronounced normative changes for certain scales and somewhat more pronounced changes for men than for women. Relationships between MMPI-2 and MMPI T-scores across scales are complex; a few MMPI-2 scales show enhancement, others show attenuation across the full range of the scale, and other scales show attenuation in the middle and lower ranges of the scale with enhancement in the upper ranges. Possible implications and effects of the new MMPI-2 T-score norms on original MMPI scale high-point elevation and high-point codes are discussed.
