The MMPI and clinical diagnosis: a comparison of classification system outcomes with discharge diagnoses

This study examined the agreement or congruence rate between clinical-discharge diagnoses rendered by a psychiatrist, and admission and discharge MMPI-derived diagnoses from four diagnostic classification systems that have been developed for the MMPI. The four classification systems included a simple high-point code based on the most elevated clinical scale in the profile, the Henrichs revision of the Meehl-Dahlstrom rules, the Goldberg equations, and a system developed by Lachar. Subjects consisted of 150 patients selected from a larger pool of patients who had completed a 9-week adult residential treatment program. Overall, this study yielded modest hit rates between 26% and 34% for MMPI-derived diagnoses and psychiatric diagnoses across the various classification systems. In addition, stability of MMPI-based diagnoses from admission to discharge assessments ranged from 48% to 51% depending on the classification system employed. Findings are discussed in terms of their implications for the use of the MMPI in patient diagnosis. It is recommended that the MMPI be used in conjunction with other sources of clinical and test information in deriving clinical diagnoses.     

Validation of an MMPI short form with literate and illiterate patients

An Improved Readability Form (IRF) of the MMPI was orally administered to 100 literate and 119 illiterate patients, and 140 literate patients were given the full MMPI with standard instructions. Profile comparisons of the MMPI with the IRF given to literates or extracted from the full MMPI yielded only small differences. The much larger differences in the IRF profiles of the illiterates were removed by controlling statistically for sex, race, age, and education. The IRF, when given to literate patients, was a good substitute for the full MMPI in predicting Brief Psychiatric Rating Scale scores. For the illiterates, the two most salient relationships with scores on the Brief Psychiatric Rating Scale were preserved, but several weaker associations were qualitatively altered. When the IRF is administered to illiterate patients, the pattern of clinical correlates may differ from those obtained with literate patients given the IRF or MMPI.     

The diagnosis of brain-damage by the MMPI: a comprehensive evaluation.

A number of research studies have proposed various methods for using the MMPI to identify brain dysfunction. This previous research has taken one of three major approaches. The present study compared the major approaches in a population consisting of 30 schizophrenic, 30 brain-damaged and 30 hospitalized normal patients. The results indicated that the most effective diagnosis device was the use of the Sc scale alone or in conjunction with the remaining clinical scales and the F scale. None of the organic scales or keys were able to match the performance of the Sc scale alone. The poor results obtained bring into question the use of these scales in any other setting without an extensive research validation. An alternate method that might be used to employ the MMPI in the diagnosis of brain dysfunction was suggested.     

Post‐event information presented in a question form eliminates the misinformation effect

This study investigated the influences of sentence surface forms on the misinformation effect. After viewing a film clip, participants received a post‐event narrative describing the events in the film. Critical sentences in the post‐event narrative, presented in either a statement or a question form, contained misinformation instead of questions with embedded false presuppositions; thus participants did not have to answer questions about the original event. During the final cued‐recall test, participants were informed that any relevant information presented in the post‐event narrative was not in the original event and that they should not report it. Consistent with previous findings, Experiment 1 demonstrated that post‐event information presented as an affirmative statement produced the misinformation effect. More importantly, post‐event information presented in a question form, regardless of whether it contained a misleading or studied item, increased the recall of correct information and reduced false recall. Experiment 2 replicated the main finding and ruled out an alternative explanation based on the salience of misleading items. Post‐event information presented in a question form created a condition similar to that which produces the testing effect.     

Sex-role orientation and psychological adjustment: comparison of MMPI profiles among college women and housewives

Androgynous, masculine, feminine, and undifferentiated women, as determined by the Bern Sex Role Inventory, were compared on the three validity and ten clinical scales of the MMPI. Two samples of women were included: Female college students and a group of upper middle-class suburban housewives. No significant differences emerged in the housewife sample. Among college women, androgynous and masculine women did not differ in adjustment, and both groups were better adjusted (i.e., less depressed, anxious, tense, and less socially introverted) than the undifferentiated women. A cross-validation study with a comparable student sample essentially replicated the results of the first study. Rather than supporting Bem's (1974) hypothesis of better psychological adjustment in androgynous persons, results were interpreted as providing support for the notion that masculinity is associated with equally good adjustment as androgyny in college women.     

Combining evidence presented simultaneously to the eye and the ear: A comparison of some predictive models

Data from a sustained monitoring experiment involving auditory, visual and combined audio-visual signal recognition were used to assess the predictive validity of five models of bisensory information processing. Satisfactory predictions of the dual-mode performance levels were made only by two models, neither of which assumes that the auditory and visual systems operate independently, and correlations which attest to this nonindependence are presented. One of these models explicitly assumes that the two systems are associated so that their judgments tend to coincide; the other assumes that the visual system “alerts” the auditory system to the presence of a signal. Both models accurately predict the levels of d’ and β in the dual-mode condition, and the “alerting” one also accounts for the observed reduction in response latencies.     

A comparison of MMPI profiles for state and private disability insurance applicants

The use of the MMPI in predicting successful rehabilitation outcomes has met with limited success. Because the motives of a disability insurance applicant may differ greatly from a disability insurance recipient, disability applicants were investigated. The MMPI scores of state disability applicants and private industrial insurance applicants were compared to a control group. Positive outcomes of test taking was possible for all three groups. Significant group differences were found for scales F, Hs, D, Hy, Pd, Pa, Pt, Sc, and Ma. Significant sex differences were found for scales Hs, D, Hy, Mf, Pt, and Sc.     

MMPI characteristics of professional prostitutes: a cross-cultural replication

The personality characteristics of 41 professional prostitutes in Brussels, Belgium, were examined using either a French- or a Flemish-language version of the Minnesota Multiphasic Personality Inventory (MMPI). A comparison group of 96 nonprostitute women was recruited from among employees of an international airline. Age differences within the prostitute group were also examined. In some contrast to prior research findings, the prostitute group was significantly more deviant on several indicators of psychopathology. Also, older prostitutes were more deviant than younger ones. An appreciable number of the women in this profession are in need of psychological treatment.     

Children's responding to live interadult conflict: The role of form of anger expression

Children's responses to interadult arguments were examined as a function of three forms of disputes: covert, verbal, and physical. Four- to seven-year-olds' overt-behavioral responses to liveenactments of arguments between a male and a female were videotaped and coded for behavioral distress and anger/aggression, and children were then interviewed. Although children exhibited overt-behavioral distress in response to all forms of disputes, physical arguments evoked the highest levels of distress. Some gender differences in responding were observed. In comparison to boys, girls exhibited more overt distress during the arguments, and wanted to stop physical arguments more frequently. The results extend findings based on the videotape methodology of the presentation of interadult arguments indicating that form of anger expression impacts children's emotional responding to interadult conflict. We wish to thank the families for contributing their time and effort to this study.     

Scoring and interpreting the MMPI with a desk-top calculator

The development of a hospital-based routine system for off-line scoring and interpreting the MMPI with a small desk-top computer (HP 9830) is described. Main features of the system include the use of optical mark reader (OMR) cards instead of ordinary answer sheets and a software monitoring system allowing operator-independent processing. In terms of flexibility, speed, and economy, the system compares favorably with other computer-based test systems.
