MMPI-2

The MMPI-2 was first published in 1989 for individuals 18 years of age or older with a 6th grade reading level. It contains 567 true-false items, which take most respondents 60-90 minutes to complete. The test can be administered by paper-and-pencil, audiocassette, or computer and scored by in-office scoring software, mail-in scoring, hand scoring, and optical scan scoring. Purchase is restricted to qualified professionals.

Short Forms

An abbreviated version of the MMPI-2 can be administered, consisting of the first 370 items, to obtain scores for validity indicators L, F, and K and the 10 clinical scales. The full MMPI-2 must be administered to obtain scores for all the validity indicators, content scales, and  supplementary scales. An alternative 180-item short form is described and reviewed below. Other short forms are noted by Friedman et al. below in Psychological Assessment with the MMPI-2.

MMPI-2 short form: psychometric characteristics in a neuropsychological setting

A 180-item short form of the MMPI-2 (MMPI-2-180) was recently developed by Dahlstrom and Archer and has been proposed for clinical use under special circumstances. This study investigated the psychometric characteristics of the MMPI-2-180 in order to delineate its strengths, limitations, and appropriate scope of clinical application. Using a neuropsychological referral sample (N = 205), we examined accuracy of the short-form as it pertains to the following (a) the prediction of basic scale scores and profile code types, (b) the identification of high-point scales, and (c) the classification of scores as pathological (T > or = 65) or normal range. The results indicate that the MMPI-2-180 provides an unreliable basis for predicting clinical code types, identifying the high-point scale, or predicting the scores on most of the basic scales. In contrast, scores on the MMPI-2-180 are accurate predictors of whether the full-scale scores fall within the pathological range (T > or = 65). These findings suggest that (a) standard interpretive procedures involving profile configuration should not be used, in most cases, with the 180-item short-form results, (b) properly interpreted, this shortened version provides potentially useful information regarding the probable presence of various problem areas, and (c) this information is very limited when contrasted with that obtained using the complete or abbreviated (i.e., 370 item) version of the MMPI-2.

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is widely used in neuropsychology, though its length (567 items) is sometimes prohibitive. This study investigated some psychometric characteristics of the 180-item version of the MMPI-2 () in order to delineate its strengths, limitations, and appropriate scope of clinical application. Limited reliability and poor predictive accuracy were recently reported for many of the MMPI-2 short-form scales in a study that used 205 brain-injured patients. In the present investigation, we used a psychiatric sample (N=186) with normal neurological findings to examine short-form accuracy in predicting basic scale scores, profile code types, identifying high-point scales, and classifying scores as pathological (T>/=65) or normal-range. The results suggest that, even as applied to neurologically normal individuals, the proposed short form of the MMPI-2 is unreliable for predicting clinical code types, identifying the high-point scale, or predicting the scores on most of the basic scales. In contrast, this short form can be used to predict whether the full-scale scores fall within the pathological range (T>/=65). These findings suggest that clinicians might be able to salvage a small amount of information from the shortened (180-item) version of the MMPI-2 when MMPI-2 protocols are incomplete. However, clinicians should not use a standard interpretive approach with this test, and routine clinical application is unwarranted. Future evaluations of short-form validity should provide a more detailed examination of individual protocols, including an analysis of the frequency of accurate prediction of full-form scores.

A Shortened Version of the MMPI-2

W. Grant Dahlstrom
University of North Carolina at Chapel Hill

Robert P. Archer
Eastern Virginia Medical School

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.
