This study investigated the utility of the MMPI-A short form described by Archer, Tirrell, and Elkins (2001) for detecting the presence of emotionality in adolescents in the school setting. Students were placed in one of three groups based on their performance on an established and frequently used self-report measure of personality, the Behavior Assessment System for Children-II (BASC- 2). Subjects who had significant elevations on one or more of the scales in Internalizing Index on the BASC-2 were placed in the Clinical group and subjects who had significant elevations on one or more of the scales the School Problems Index or Personal Adjustment Index were placed in the Adjustment group. Those without significant elevations on the BASC-2 were placed in the Nonclinical group. Differences between the three groups on each of the MMPI-A short form clinical scales were reported. The results indicated that the students in the Clinical group scored higher than students in the Non-clinical group on each of the MMPI-A short form scales. Adjustment group scores tended to be higher than Non-clinical group scores but not all scales were significantly higher. Discriminant analysis correctly classified 75% of the non-clinical group, 52% of the Clinical group, but only 37% of the Adjustment group. These findings, combined with additional analysis of clinical relevant data, provided positive indicators supporting the use of the short form in clinical settings.

The Minnesota Multiphasic Personality Inventory (MMPI) has a long history of identifying adolescents who are at risk of displaying delinquent behaviors. However, MMPI research regarding behaviors observed from adolescents while incarcerated is non-existent. This dissertation examines the usefulness of the adolescent version of the MMPI (MMPI-A; Butcher et al., 1992) in predicting specific unit infractions for female juvenile delinquents incarcerated in a state facility in Texas. Unit infractions were placed into groups based on behavioral relatedness. MMPI-A scales were selected for analyses based on behavioral descriptors related to unit infractions. Logistic regression was performed to test whether elevated MMPI-A scales, dichotomized at 55T, 60T, 65T and 70T could predict behaviorally related groupings. Analyses suggest that the MMPI-A is not very useful in statistically predicting unit infractions.

The aim of this study is to offer a profile detector of the falsifications that could be done to the MMPI-2. We propose minimal changes in the reversed order of the direct punctuations of L y K and the addition of four new specific scales: Odecp, Ds-r, S, F-K. Two groups were used: a control group, composed by normal and clinical subgroups who answered to the MMPI-2 according to standard procedure, and an experimental group, composed by three subgroups with different answer instructions: to give a good image, a bad image or an inconsistent answer. The result is a profile with the proposed scales of validity that initially allow the detection of different falsifications by the subjects when answering the MMPI-2 test. / Se propone un perfil detector de las falsificaciones que se dan con el MMPI-2, proponiendo la inversión de las puntuaciones directas de L y K y añadiendo cuatro nuevas escalas específicas: Odecp, Ds-r, S, F-K. Para esto se formaron dos grupos: control, compuesto por los subgrupos normal y clínico que contestan de forma estándar al MMPI-2, y experimental, formado por tres subgrupos instruidos para contestar al MMPI-2 de una manera determinada: mostrando buena imagen, mala imagen y de forma inconsistente. El resultado de este estudio es un perfil con las escalas de validez propuestas para la detección de las distintas falsificaciones que pueden realizar los sujetos que han contestado al cuestionario del MMPI-2.

The MMPI answer sheets of 30 psychiatric and 30 non-psychiatric patients at a Veterans Administration Hospital were scored for the standard MMPI and the scales of kincannon's 71-item Mini-Mult. Correlational data demonstrated good correspondence between the MMPI and the Mini-Mult for groups. Correlations ranged from .62 to .85 for the psychiatric group and from .20 to .81 for the non-psychiatric group. The psychiatric group was somewhat superior to the non-psychiatric group in terms of correspondence, which was expected. Individual profile pairs were also compared. An analysis of the validity scales, high points, and gerneral elevation indicated that the individual Mini-Mult profile was, in many cases, a poor predictor of its corresponding MMPi profile. Though the utility of the Mini-Mult in clinical practice is minimal, it could be usefully empolyed forresearch in group comparison.

The objective of this study is to assess the diagnostic accuracy of the personality of the Mexican criminal with the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). The inventory was administered to 1,740 Mexican participants of which 870 (728 male and 142 female) are prison inmates, processed and/or sentenced for various crimes from various prisons in Mexico City, and the other 870 participants (728 male and 142 female) are not prison inmates. The ROC (Receiver Operating Characteristic) curve analysis was used to assess the level of diagnostic accuracy through indexes of the Area below the curve (ABC), sensitivity (S) and specificity (E). The analysis was differentiated by gender and showed significant differences / El objetivo de este estudio es poder apreciar la precisión diagnóstica de la personalidad del delincuente mexicano con la prueba del Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Se administró la prueba a un total de 1740 participantes mexicanos de los que 870 (728 varones y 142 mujeres) son reclusos, procesados y/o sentenciados por diferentes delitos, procedentes de diversas cárceles del Estado y Distrito Federal, y otros 870 (728 varones y 142 mujeres) son personas no reclusas. Se utilizó el análisis de la curva ROC (Receiver Operating Characteristic) para apreciar el nivel de precisión diagnóstica a través de sus índices del Área Bajo la Curva (ABC), su Sensibilidad (S) y Especificidad (E). El análisis, diferenciado por género, mostró notables diferencias. / O objetivo do presente estudo consiste em avaliar a precisão diagnóstica da personalidade do delinquente mexicano através da prova Minnesota Multiphasic Personality Inventory-2 (MMPI-2). A prova foi administrada a 1.740 participantes mexicanos, dos quais 870 (728 homens e 142 mulheres) são reclusos, julgados e condenados por diferentes delitos, procedentes de diferentes estabelecimentos prisionais da cidade do México, e outros 870 (728 homens e 142 mulheres) são pessoas não reclusas. Foi utilizada uma análise da curva de ROC (Receiver Operating Characteristics) para avaliar o nível de precisão diagnóstica através dos índices da Área Abaixo da Curva (ABC), sua sensibilidade (S) e Especificidade (E). A análise de diferenciação entre sexos revelou diferenças significativas.

A study of the personality characteristic as measured by the Minnesota Multiphasic personality Inventory (MMPI) was made of an experimental group of students brought before the Standards Committee at Utah State University for infractions against the school's code of conduct. It was then compared with personality characteristics of a control group representing the remaining student body. The result was no significant difference between the two groups on any of the MMPI scales. After checking the activities of the two groups, it was found that the experimental group was lower in grade point average than the general student body, but this difference was not statistically significant. However, in the area of involvement in school, church, and community activity, the difference was significant, The experimental group ranged from low to medium while the control group varied from medium to high.

The purpose of this study was to determine whether the Minnesota Multiphasic Personality Inventory (MMPI) could be used to discriminate between Vietnam veterans with Post-Traumatic Stress Disorder and those with other mental disorders. Scores on the 13 validity and clinical scales of the MMPI were used as predictor variables in two discriminant analyses. The first of these was performed in replication of studies in which cases of substance-abuse disorder were eliminated from the non-PTSD comparison group. Substance- abuse cases were included in the second discrimination. The results indicated that while the MMPI can be used to discriminate PTSD from non-PTSD veterans, this discrimination is weakened by the presence of cases with substance abuse disorders in the non-PTSD comparison group.

The 567-item MMPI-2 is the most widely used personality measure; it requires a sixth-grade reading level, takes 60-90 minutes to administer, and reports robust psychometrics. However, traumatic brain injury (TBI) sequelae can cause cognitive deficits that affect test-taking abilities and item endorsement during differential diagnoses of neurological and personality factors. Therefore, this study examined the clinical utility of the shortened 338-item MMPI-2-RF inventory with a post-acute TBI population as a practical alternative. The MMPI-2-RF requires a fifth-grade reading level and takes 35-50 minutes to administer. The MMPI-2-RF also includes revised versions of the MMPI-2 Validity Scales and new substantive scales that may better psychometrically account for personality in TBI sequelae, such the Somatic/Cognitive Scales. This study conducted an incremental validity analysis of the MMPI-2-RF with a non-litigating, post-acute care TBI population in Central Texas. The goal of the study was to explore the measure’s performance, or its ability to capture functional dimensions in a TBI sample. More specifically, the study examined the construct validity of MMPI-2 to MMPI-2-RF Validity and Restructured Clinical Scales, and criterion validity for the Somatic/Cognitive Scales with neuropsychological and neurobehavioral functioning measures. An archival neuropsychological database (N = 60) was analyzed of patients who participated in TBI rehabilitation treatment at a Central Texas hospital. MMPI-2-RF profiles were retrospectively scored with MMPI-2 archival data. Statistical analysis between MMPI-2 to MMPI-2-RF Validity and Restructured Clinical Scales was conducted. MMPI-2-RF Somatic/Cognitive Scales and criterion measures of Weschler Adult Intelligence Scale, 4th Edition (WAIS-IV), The Weschler Memory Scales, 4th Edition (WMS-IV), The Booklet Category Test, 2nd Edition (BCT), and the Neurobehavioral Functioning Inventory (NFI) were examined. Patient demographics and measurement qualities were reported with the sample. / text

abstract: The purpose of this study was to evaluate whether five select scales of the MMPI-A (F, Scale 2, A-dep, A-lse, and A-aln) are predictive of a diagnosis of a major depressive episode according to the current DSM-IV-TR criteria. Participants were 90 girls and 58 boys in a clinical psychiatric setting. The study examined two separate hypotheses across the five scales. The first set of hypotheses tested whether a significant T-score on each of the five scales would predict a diagnosis of a major depressive episode in clinical adolescents. The second set of hypotheses attempted to step away from the constraints of diagnostic and statistical cut-off criteria and evaluated the ability of discrete T-scores of the MMPI-A in predicting the number of symptoms of a major depressive episode in clinical adolescents. Results indicated that none of the five scales were predictive of a diagnosis of a major depressive disorder in clinical adolescents. All but one scale (Scale 2) was significant in its ability to predict the number of depressive symptoms in clinical adolescents. Implications of this study include the need for a better diagnostic criteria for adolescent depression as well as re-evaluating the cut-off criteria of scales on the MMPI-A. Directions for future research are also discussed. / Dissertation/Thesis / Ph.D. Counseling Psychology 2010
