A Shortened Version of the MMPI-2

Abstract

A psychometrically sound method of prorating scores from a shortened version of the MMPI-2 is presented to approximate the full-scale raw scores on the basic scales. After a brief review of the history of short versions of the original MMPI and their strengths and weaknesses, justifications for developing and publishing this new version are offered. In spite of the risk of abuse by harassed and over-worked clinicians, there are cogent reasons to make this set of procedures available to practitioners and research investigators. These procedures were devised on the data from the 2,600 men and women in the original MMPI-2 restandardization sample and cross-validated on a sample of 632 test records from a psychiatric inpatient service. The dependability of estimated single raw scores as well as of the patterning of the prorated profile patterns is explored.
