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.     

Development and preliminary validation of a semi-structured interview for the screening of law enforcement candidates

A standard practice among most law enforcement agencies is to include psychological screening in the selection of job candidates. Although the use of personality tests in predicting job performance of law enforcement officers has received empirical support (e.g., the Minnesota Multiphasic Personality Inventory, the Inwald Personality Inventory), there is a conspicuous absence of data regarding the reliability and validity of interview procedures. The present study represents the first step in the development of a standardized, semi-structured interview for use in the screening of law enforcement personnel. This interview, the Law Enforcement Candidate Interview, was constructed using content areas drawn from measures used in the screening of law enforcement personnel (e.g., Inwald Personality Inventory) and assessment of personality functioning (Structured Clinical Interview for DSM-III-R Personality Disorders). This interview was then administered by two doctoral students to a group of law enforcement academy cadets (n=34). A modest degree of inter-rater reliability was achieved, although internal consistency was somewhat lacking. Interview scores were correlated with measures of academy performance (final grade-point average and peer and supervisor ranking of academy performance). Results of these analyses suggest the LECI is a modest predictor of academy performance. Potential uses of the LECI and future research indications are outlined.     

Principal components analyses of the MMPI-2 PSY-5 scales: identification of facet subscales

The Personality Psychopathology Five (PSY-5) is a five-factor personality trait model designed for assessing personality pathology using quantitative dimensions. Harkness, McNulty, and Ben-Porath developed Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scales based on the PSY-5 model, and these scales were recently added to the standard MMPI-2 profile. Although the PSY-5 constructs are multidimensional in definition, explicit subscales for the broader PSY-5 scales have not been developed. The primary goals of this study were to empirically derive subscales for the MMPI-2 PSY-5 scales using principal components analysis (PCA) and to replicate these subscales with an independent sample. Individual PSY-5 scales were analyzed using PCA with an initial sample of 4,325 MMPI-2 protocols, and the component structure was replicated with a second sample of 4,277 MMPI-2 protocols. A third sample of 4,327 protocols was used to further evaluate the internal consistency reliabilities of the resulting facet subscales. Overall, replicable facet subscales were identified with content areas that are largely congruent with Harkness and McNulty's model.     

Psychometric and structural analysis of the MMPI-2 Personality Psychopathology Five (PSY-5) facet subscales

The Personality Psychopathology Five (PSY-5) is a model of personality psychopathology assessed in adult populations with a set of Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scales. The authors examine the reliability and validity of recently developed lower-order facet subscales for each of these five domains, with an emphasis on structural invariance, using both confirmatory factor analysis (CFA) and exploratory factor analysis (EFA). MMPI-2 protocols completed by psychiatric patients (N = 693) served as the data source. The reliability and discriminant validity of the subscales were mostly inadequate. Results from the CFAs reveal universally poor statistical fits. Subsequent EFAs extracted alternate latent structures, which also demonstrate mostly inadequate reliability and validity. Overall, results suggest that the item pool that forms the MMPI-2 PSY-5 domain scales may not be able to sustain meaningful facet subscales.     

An examination of the MMPI-2 Wiener-Harmon Subtle subscales for D and Hy: implications for parent scale and neurotic triad interpretation

This research explores the scale development process for the MMPI-2 Wiener and Harmon (1946) Subtle subscales for Depression (D) and Hysteria (Hy) to provide insight into why certain items were included on these scales and were subsequently but inappropriately assumed to be subtle indicators of the same pathology that the Obvious items measure. In this research, I also explore what the Subtle scales on D and Hy measure and their potential utility for the interpretation of their parent scales and the "neurotic triad." It was hypothesized that the D and Hy Subtle subscales are related to denial, repression, or both and this hypothesis was supported. In a sample of 1,240 inpatient and outpatient psychiatric patients at a large Army medical center, it was found that these subscales had strong positive correlations with othe scales on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom. Graham, Tellegen, & Kaemmer, 1989) related to denial, repression, or both. It was also found that they had strong negative correlations with scales on the MMPI-2 and Millon Clinical Multiaxial Inventory (MCMI-II; Millon, 1987) that are related to symptom endorsement, which can be considered the opposite of denial or repression. In addition, ratings of the Subtle items on D and Hy by clinical psychology residents were consistent with the hypothesis that these items reflect a denial of psychological or physical dysfunction.     

MMPI-2 in the inpatient assessment of women with eating disorders

The MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) reveals similar patterns across all Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) eating-disorder diagnoses. In this study, 550 women with eating disorders completed the MMPI-2. The 3 highest mean elevations for all eating-disorder diagnostic groups occurred on the same scales in the same order: 2, 7, and 3. The modal code for all groups was 2-7/7-2. However, multivariate analyses using the 16 validity and clinical scales, as well as the 27 content and supplementary scales, indicated that the MMPI-2 also distinguishes among eating disorders, especially in that patients with restricting anorexia report less psychopathology than other groups. These results are compared with the results of past eating-disorder research that used the older MMPI (Hathaway & McKinley, 1983).     

Police/law enforcement and psychology

The number of areas of interface between psychology and law enforcement has grown sharply in the past few decades. At the same time the field of law enforcement-related psychology has acquired increased knowledge and sophistication based on extensive research and practical experience. Areas of interface between law enforcement and psychology include selection of police officer candidates; fitness-for-duty evaluations; prevention and treatment of stress-related disorders; hostage negotiation; psychological profiling of terrorists and mass murderers; and eyewitness testimony. Trends and developments in these areas are surveyed in this article.     

Personality assessment in neuropsychology: the nonspecificity of MMPI-2 neurocorrection methods

Three established methods of neurocorrection claim to improve Minnesota Multiphasic Personality Inventory (MMPI)/MMPI-2 validity with closed-head injury (CHI) patients. These methods (which suggest removing "neurological" items from scoring) were employed here comparing 35 CHI patients with 35 psychiatric patients with elevated profiles. The 14-item correction changed 2-point codes for 41% of CHI and 31% of psychiatric profiles, the 30-item system changed 77% of CHI and 71% of psychiatric profiles, whereas the 37-item system changed 80% of CHI and 71% of psychiatric profiles. There were no significant differences between the two groups in number of profiles changed or number of neurocorrective items endorsed. Using each of the three correction systems, the following percentage of profiles remained elevated: 99%, 87%, and 89%, respectively.     

Personality assessment without borders: adaptation of the MMPI-2 across cultures

In contemporary psychology, personality assessment knows few national or cultural boundaries. Psychological tests developed in one country are often translated and adapted into cultures that might appear to be greatly different from the country of origin. In this article, I address the factors that are important to international test adaptation and examine problems that can adversely affect cross-cultural test research programs. I address qualities important for verifying the accuracy and adequacy of cross-cultural assessment. I review the extensive adaptation of the MMPI (Hathaway & McKinley, 1940) and MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989), the most frequently used personality measure. I highlight several contemporary research trends in international personality assessment.     

Dimensions of deception in personality assessment: the example of the MMPI-2

The topic of deception in personality assessment is discussed along a number of dimensions relevant to clinical practice. The dimensions described are consistency versus accuracy of item endorsement, simulation versus dissimulation, genetic versus specific deception, crude versus sophisticated deception, intentional versus nonintentional deception, self-deception versus impression management, and selectivity versus inclusiveness, as these may be encountered using the revised version of the Minnesota Multiphasic Personality Inventory. The emphasis is placed on deceptive strategies as operations as distinct from the traditional categories of response style such as social desirability. Directions for future research are indicated.     

The predictive validity of peer assessment in law enforcement: a 6 year follow-up

This study examined the relations between peer assessment and long-term law enforcement/job performance. Sixty-nine law enforcement cadets completed peer rankings of likelihood of success in job performance. These peer rankings were significantly correlated with supervisor ratings, as well as absenteeism and retention, after 1 year of employment. In the present study, both subjective and objective job performance data were collected from a variety of employing job performance agencies after 6 years of employment. Peer rankings were still significantly correlated (r=.40, p<.05) with retention after 6 years, but were not significantly correlated to any job performance index. These results support the potential usefulness of peer assessment data even after several years have passed. © 1998 John Wiley & Sons, Ltd.     

Psychological hardiness predicts successful selection in a law enforcement special operations assessment and selection course

We studied the predictive effects of psychological hardiness on successful selection in a United States federal tactical law enforcement assessment and selection (A&S) program. Seventy‐one male experienced law enforcement personnel participated in a week‐long, physically and psychologically rigorous A&S course. Dispositional Resilience Scale (DRS‐15) Total Hardiness scores predicted selection in this select sample. Age and cognitive ability moderated the predictive effects of psychological hardiness such that hardiness predicted selection in younger candidates and candidates with higher cognitive ability. Similar findings were obtained for DRS Commitment. DRS‐15 Control facet also differentiated selection in this sample but the predictive effects did not hold when age and cognitive ability were controlled. Findings extend the application of the DRS‐15 to law enforcement personnel selection and highlight the importance of examining moderating effects of psychological hardiness.     

Use of the MMPI-2 in American Indians: I. Comparability of the MMPI-2 between two tribes and with the MMPI-2 normative group

The comparability of the MMPI-2 in American Indians with the MMPI-2 normative group was investigated in a sample of 535 Southwestern and 297 Plains American Indian tribal members with contrasting sociocultural and historical origins. Both American Indian tribal groups had clinically significant higher T scores (> 5 T points) on 5 validity and clinical scales, 6 content scales, and 2 supplementary scales than did the MMPI-2 normative group. There were no significant differences between the 2 tribal groups on any of the MMPI-2 clinical, content, or supplementary scales. Matching members of both tribes with persons in the MMPI-2 normative group on the basis of age, gender, and education reduced the magnitude of the differences between the 2 groups on all of these scales, although the differences in T scores still exceeded 5 T points. It appears likely that the MMPI-2 differences of these 2 American Indian groups from the normative group may reflect their adverse historical, social, and economic conditions.     

New frontiers in the relationship between suicidology and law enforcement

This paper reviews some historic ties between crisis intervention and the beginning of suicidology. It reviews the author's involvement in suicidology and law enforcement, in terms of crisis intervention, management of the man with a gun, studies of suicide among police, bereavement of widows of slain police officers, jailer stress, psychological aspects of kidnapping, kidnappers, victim survival in kidnapping, hostage negotiation, and application of the psychological autopsy to homicide investigation. In addition, the development of a program to offer survivor counseling for those whose loved ones have been killed and for those whose loved ones were the killers is described. Other new areas for suicidology application are outlined in terms of survivors, industry, and school.     

Similarities and differences between MMPI and MMPI-2 applications to the assessment of posttraumatic stress disorder

The purpose of this study was to address the question: Is the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) comparable to the original MMPI in its applicability to the assessment of posttraumatic stress disorder (PTSD) among Vietnam combat veterans? The question was addressed by administering both the original MMPI and MMPI-2 to 29 subjects classified as meeting Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; DSM-III-R) criteria for PTSD and comparing MMPI and MMPI-2 scores in terms of: degree of association, code-type congruence, diagnostic hit rates (when compared to two other clinical samples, and one normal sample), and congruence of the Keane PTSD Scale (PK). Results reveal highly significant correlations between MMPI and MMPI-2 basic scales for the PTSD sample as well as congruence in 2-point codes comparable to previous studies. The MMPI-2 was found to identify effectively PTSD subjects from the other groups. Results also showed a high degree of association between the MMPI and MMPI-2 in regard to PK scores, although minor differences were found in PK raw scores between the two tests. Overall, the findings suggest a high degree of comparability between the MMPI and MMPI-2 in the assessment of PTSD.     

A Structural Analysis of the Impact of MMPI-2 on MMPI-1

Minnesota Multiphasic Personality Inventory-1 (MMPI-1) items modified for Minnesota Multiphasic Personality Inventory-2 (MMPI-2) are presented in pairs to illustrate modifications. MMPI-1 items deleted from MMPI-2 are presented, grouped by categories. Frequencies of items remaining in MMPI-2 for the following special scales are presented: Harris and Lingoes subscales of the clinical scales (Harris & Lingoes, 1955/1968); Wiggins Content scales (Wiggins, 1966); Tryon, Stein, and Chu (TSC) cluster scales (Stein, 1968; Tryon, 1966); Indiana Rational scales (Levitt, 1989); and selected other special scales. Frequencies of MMPI-1 items in the MMPI-2 validity and content scales are also presented, k is concluded that most of the special scales developed for MMPI-1 remain relatively intact in MMPI-2.     

Objective personality assessment of people in diverse cultures: European adaptations of the MMPI-2

This article examines the cross-national application of psychological tests and examines the generalizability of objective psychological assessment instruments. The most widely used and internationally adapted personality instrument, the Minnesota Multiphasic Personality Inventory (MMPI-2), is highlighted to illustrate the adaptation of psychological tests across the barriers of language and culture. The problems and limitations of using questionnaire methods were noted and effective strategies for translating, adapting, and standardizing questionnaires in languages and cultures different from their country of origin are reviewed. The history of several European adaptations of the original MMPI and MMPI-2 is surveyed to illustrate the extensive research base for the test in Europe. Applications of the MMPI-2 in clinical and non-clinical (e.g. industrial) settings were noted. Current research is described and recommendations for future research are provided.
