It was replaced by an updated version, the MMPI-2, in 1989. A version for adolescents, the MMPI-Hypomanic personality scale pdf, was published in 1992. Many additions and changes to the measure have been made over time to improve interpretability of the original Clinical Scales.
Additionally, there have been changes in the number of items in the measure, and other adjustments. Restructuring the Clinical Scales was the initial step toward addressing the remaining psychometric and theoretical problems of the MMPI-2. The MMPI-2-RF contains 338 items, contains 9 validity and 42 homogeneous substantive scales, and allows for a straightforward interpretation strategy. The rest of the measure was developed utilizing statistical analysis techniques that produced the RC Scales as well as a hierarchical set of scales similar to contemporary models of psychopathology to inform the overall measure reorganization. The entire measure reconstruction was accomplished using the original 567 items contained in the MMPI-2 item pool.
