Assessing depression with the MMPI and MMPI-2

The usefulness of the MMPI (Hathaway & McKinley, 1951 ) and MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) for diagnosing and assessing symptomatic depression has been the subject of considerable debate for a number of years. In this article, we review the relative contributions of the MMPI and MMPI-2 clinical and content scales in predicting depression. Positive predictive power, negative predictive power, and overall classification rate were computed for Scale 2 (D) of the MMPI and MMPI-2 and the Depression content scale (DEP) of the MMPI-2. Scale 2 (D) of both the MMPI and MMPI-2 appears to be moderately accurate in predicting depression. Although some studies suggest that the content scale DEP provides incremental validity over Scale 2 (D) of the MMPI-2, the results of this review indicate that the content scale DEP of the MMPI-2 does not exceed the diagnostic efficiency of Scale 2 in predicting depression.     

The consistency of scores and configural patterns between the MMPI and MMPI-2

This article is an extension of the Ben-Porath and Butcher (1989a) study, investigating the claim that the scores and configural patterns of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) are consistent with those of the Minnesota Multiphasic Personality Inventory (MMPI). College students (200 men and 200 women) were randomly assigned to either the original to original condition (O-O), in which they took the MMPI twice, or the original to revised condition (O-R), in which they took the MMPI and the MMPI-2. Correlations and configural patterns of the O-O condition were compared to those of the O-R condition. Results suggest some score changes between the MMPI and MMPI-2, particularly on Scales L, 5, and 8 for men and Scales L and 5 for women.     

Profile validity standards for MMPI and MMPI-2 F scales

Although numerous indices of validity have been developed for the MMPI and MMPI-2, interest in the F scale and its variants continues, especially among practicing clinicians. The use of the binomial for assessing standards for random answering and possibly for judgments of malingering offers another approach for the interpretation of F-scale scores. The theoretical binomial distribution and Monte Carlo data are in accord. Cut-off scores of 24 for the MMPI and 23 for the MMPI-2 suggest random responses, and scores of 40 and 37, respectively, suggest clinical interpretation rather than randomness of responding.     

Comparison of the MMPI and MMPI-2 Among Job Applicants

The primary objective was to compare the MMPI-2 profiles for professional job applicants with corresponding profiles on the original MMPI. Male and female MMPI-2 profiles were also compared, and correlational and factor analyses were used to examine: A) Interscale correlations vis-à-vis item overlap, and B) The impact of K-corrections. The subjects were 82 auditor applicants, plus 212 sales and management applicants from an earlier study. The original MMPI was found to overpathologize applicant profiles. Male and female MMPI-2 profiles differed only on Mf. Scales L, K, and Hy formed a favorable cluster for job applicants, while F, Hs, Pt, Sc formed one unfavorable cluster—and D, Si a second. K-corrections consistently moved clinical scales in the direction of the favorable cluster.     

The Clinical Application of MMPI Special Scales/MMPI Supplemental Scale Manual (Book)

Two studies involving a total of 200 participants examined the effect of individual versus group test administration on Rorschach Oral Dependency (ROD) scores. In Study 1, 60 college students completed the ROD scale via a group administration, and 60 students completed individual Rorschach protocols from which ROD scores were derived. Analyses revealed no differences in ROD means and standard deviations and no differences in the form of the ROD score distributions (i.e., skewness and kurtosis) as a function of mode of test administration. Virtually identical results were obtained in Study 2 (N = 80), where a within-participants design was used in lieu of the between-participants design of Study 1. Implications of these findings for the construct validity of the ROD scale are discussed.     

Comparative accuracy of the MMPI-2 and the MMPI-A in the diagnosis of psychopathology in 18-year-olds

Both the Minnesota Multiphasic Personality Inventory--2 (MMPI-2) and the Minnesota Multiphasic Personality Inventory--Adolescent (MMPI-A) may be administered to 18-year-olds. Each test was administered to 18-year-old participants classified as psychopathology present (PP) or psychopathology absent (PA) to assess (a) the degree of correspondence between the 2 test versions in yielding clinically elevated or nonclinically elevated profiles and (b) the relative accuracy of the 2 test versions in identifying the presence of psychopathology. The 2 tests produced profiles that were inconsistent in clinical elevation status in 70 of 152 participants (46%). All 70 participants with incongruent profiles had clinically elevated MMPI-2 scores and normal-range MMPI-A scores. Analyses of incongruent profiles obtained by PP and PA participants indicated that 18-year-olds were overpathologized by the MMPI-2 and underpathologized by the MMPI-A.     

The Consistency Between Scores of the Harris-Lingoes Subscales of the MMPI and MMPI-2

This study investigates the consistency between scores of the Harris-Lingoes subscales of the Minnesota Multiphasic Personality Inventory (MMPI) and the MMPI-2. College students (200 men and 200 women) were randomly assigned to either the original to original condition, where they took the MMPI twice, or the original to revised condition, where they took the MMPI and MMPI-2. Results indicate relative consistency in the item and normative changes between the Harris-Lingoes subscales of the MMPI and MMPI-2. These results suggest that the recommendation of a clinical significance score of T > 65 for the MMPI-2 scales should not be applied to the Harris-Lingoes subscales.     

Scale 5 of the MMPI and MMPI-A: evidence of disparity

Scale 5 of the MMPI and MMPI-A was compared in a repeated measures design. Participants for the study were 43 adolescents classified as emotionally disturbed in a public school system and 17 inpatients at a residential treatment center. The MMPI Scale 5 mean score was substantially higher than that of the MMPI-A. The alternate-form reliability between Scale 5 of the two forms was surprisingly low, suggesting that the deletion of 16 items and rewording of 6 additional items changed the scale on the MMPI-A to an extent that may have significantly altered the underlying construct. The authors discuss factors that could be associated with the findings, including: (a) the diminished ability to express feminine interest on the MMPI-A, and (b) general changes in attitudes among adolescents over the 3 or more decades since the MMPI norms were developed.     

The MMPI-2 computerized adaptive version (MMPI-2-CA) in a Veterans Administration medical outpatient facility

The ability to screen quickly and thoroughly for psychological difficulties in existing and returning combat veterans who are seeking treatment for physical ailments would be of significant benefit. In the current study, item and time savings, as well as extratest correlations, associated with an audio-augmented version of the computerized adaptive Minnesota Multiphasic Personality Inventory-2 (MMPI-2-CA) are examined in a group of 273 male veterans, ages 26-87 years. Results indicated an average item savings of approximately 103 items (18.6%), with a corresponding time savings of approximately 12 min (24.3%), for the MMPI-2-CA compared with conventional computerized administration of the test, as well as comparability in terms of test-retest coefficients and correlations with external measures. Future directions of adaptive personality testing are discussed.     

A Practical Guide to the MMPI (Book)

The projective imagery, artwork, and behavior of an artistically trained psychiatric patient are presented 10 years after having committed a murder. The case is examined to see whether the Rorschach responses and the artist's choice of subject matter demonstrate the repetition compulsion familiarly associated with trauma. Additionally, does psychotherapy in which the crime is remembered serve as a stimulus to these other forms of repetition? Our case shows evidence of a continuing psychological struggle to express or deny his involvement in the murder, with phases of limited resolution.     

Comparison of the MMPI and MMPI-2 administered to Anglo- and Hispanic-American university students

The MMPI and MMPI-2 were administered to White and Hispanic-American subjects. Multivariate analyses revealed significant differences for three main effects: test form, ethnicity, and gender. Two-way interactions between gender and test form and between gender and ethnicity were both significant, but the other two-way interaction (Test Form x Ethnicity) and the third-order interaction (Test Form x Ethnicity x Gender) were not significant. Univariate analyses comparing MMPI and MMPI-2 revealed significant differences on 12 of 13 scales, and comparison of Anglos and Hispanics resulted in significant differences on 4 scales. When Anglos and Hispanics taking the MMPI and MMPI-2 were compared, however, no significant differences on any scales occurred. Results suggest that, for these Hispanic subjects, the MMPI-2 introduces no new or additional differences and may be employed and interpreted essentially the same as the MMPI.     

Diagnostic construct validity of MMPI-2 Restructured Form (MMPI-2-RF) scale scores

In the current investigation, the authors examined the diagnostic construct validity of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) in a patient sample. All participants were diagnosed via the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I/P). The data set used in this study was composed of 544 patients--67 with bipolar disorder, 407 with major depressive disorder, and 70 with schizophrenia. Multivariate analyses revealed a pattern of mean scale differences among patient groups that was mostly consistent with the prominent features of each diagnostic group; logistic regression analyses identified a number of scales that were strong, unique predictors in the differentiation between pairs of diagnostic groups. The higher order scales (H-O)--the Emotional/Internalizing Dysfunction (EID) and Thought Dysfunction (THD) scales were most useful in differentiating between patient groups. For differentiating bipolar disorder patients from the other diagnostic groups, the Activation (ACT) Specific Problem scale was most useful. Although not all hypothesized scale differences emerged; overall, the pattern of results provides support for the diagnostic construct validity of the MMPI-2-RF scales.     

How (not) to evaluate the comparability of MMPI and MMPI-2 profile configurations: a reply to Humphrey and Dahlstrom

Humphrey and Dahlstrom (1995) presented a study on the comparability of MMPI/MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) profiles in which they concluded that "the bases for clinical interpretation derived from the MMPI and MMPI-2 profiles were sufficiently at variance to require different conclusions" [sic] (p. 2). In this brief critique, we identify procedural and data-analytical deficiencies that invalidate Humphrey and Dahlstrom's argument. Their blanket recommendation based on this argument, namely, that clinicians routinely plot both MMPI and MMPI-2 profiles, is unwarranted.
