The comparative validity of MCMI-II and MMPI-2 personality disorder scales with forensic examinees.

This study demonstrated the convergent and discriminant validity of the MMPI-2 and MCMI-II personality disorder scales with forensic examinees. Based on averaged correlational data, the scales performed comparably with previous findings in psychiatric samples. Furthermore, the scales demonstrated increased convergent correlations. Improved convergence was obtained for the Antisocial, Sadistic, Borderline, Schizotypal and Paranoid scales. Decreased convergence on the Dependent and Avoidant scales was also obtained.     

Pathological gambling and personality disorders: a pilot-study with the MCMI-II

In this paper, the most frequent personality disorders related to pathological gambling are described. A sample of 50 pathological gamblers, who were assessed with the MCMI-II before treatment, and of 50 normative subjects from general population with the same demographic features (age, sex and socioeconomic level) was selected. According to the results, the 40% of clinical sample (versus the 14% of normative sample) showed at least one personality disorder. The most prevalent one was the Narcissistic (32%), followed by the Antisocial and Passive-Aggressive (16% each one of them). Furthermore, the gamblers with personality disorders presented an average of 2.2 disorders and tended to be more impulsive. Likewise pathological gamblers abused of alcohol, showed a mild anxiety and were not so adapted to everyday life as much as the control group. Finally, implications of this study for clinical practice and future research in this field are commented upon.     

An examination of three sets of MMPI-2 personality disorder scales

Three sets of personality disorder scales (PD scales) can be scored for the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). Two sets (Levitt & Gotts, 1995; Morey, Waugh, & Blashfield, 1985) are derived from the MMPI (Hathaway & McKinley, 1983), and a third set (Somwaru & Ben-Porath, 1995) is based on the MMPI-2. There is no validity research for the Levitt and Gotts scale, and limited validity research is available for the Somwaru and Ben-Porath scales. There is a large body of research suggesting that the Morey et al. scales have good to excellent convergent validity when compared to a variety of other measures of personality disorders. Since the Morey et al. scales have established validity, there is a question if additional sets of PD scales are needed. The primary purpose of this research was to determine if the PD scales developed by Levitt and Gotts and those developed by Somwaru and Ben-Porath contribute incrementally to the scales developed by Morey et al. in predicting corresponding scales on the MCMI-II (Millon, 1987). In a sample of 494 individuals evaluated at an Army medical center, a hierarchical regression analysis demonstrated that the Somwaru and Ben-Porath Borderline, Antisocial, and Schizoid PD scales and the Levitt and Gotts Narcissistic and Histrionic scales contributed significantly and meaningfully to the Morey et al. scales in predicting the corresponding MCMI-II (Millon, 1987) scale. However, only the Somwaru and Ben-Porath scales demonstrated acceptable internal consistency and convergent validity.     

MMPI-2 personality profiles of high-functioning adults with autism spectrum disorders

The Minnesota Multiphasic Personality Inventory-Second Edition was administered to 20 adults with autism spectrum disorders (ASD) who fell in the average to above average range of intelligence and 24 age-, intelligence-, and gender-matched college students. Large group differences, with the ASD group scoring higher, were found on the L validity scale, Clinical Scales 2 (D) and 0 (Si), Content scale Social Discomfort (SOD), Supplementary scale Repression (R), and Personality Psychopathology Five (PSY-5) scale INTR (Introversion). The proportion of ASD adults scoring in the clinical range on these scales was between 25% and 35%. High scores on these scales are consistent with the clinical picture of Asperger syndrome and high-functioning autism in adulthood. Future directions and implications for identifying adults in need of a specialized autism assessment are discussed.     

Integrating psychopathology and personality disorders conceptualized by the MMPI-2-RF and the MCMI-III: a structural validity study

The Minnesota Multiphasic Personality Inventory-2-Restructured Form (Ben-Porath & Tellegen, 2008 ) Restructured Clinical scales and Higher Order scales were linked to the Millon Clinical Multiaxial Inventory-III (Millon, Millon, Davis, & Grossman, 2009 ) personality disorder scales and clinical syndrome scales in a Flemish/Dutch sample of psychiatric inpatients and outpatients, substance abuse patients, correctional inmates, and forensic psychiatric patients (N = 968). Structural validity of psychopathology and personality disorders as conceptualized by both instruments was investigated by means of principal component analysis. Results reveal a higher order structure with 4 dimensions (internalizing disorders, externalizing disorders, paranoid ideation/thought disturbance, and pathological introversion) that parallels earlier research on pathological personality dimensions as well as research linking pathological personality traits with mental disorders. Theoretical and clinical implications are considered.     

Assessing psychopathic personality traits with the MMPI-2

In this study, we examined the utility of the MMPI-2 (Butcher et al., 2001) in assessing psychopathic personality traits. We explored whether MMPI-2 scales that measure affective and interpersonal traits add to the instrument's social deviance measures in assessing global psychopathy and its two facets. Our study of 281 male and female college students indicates that the MMPI-2 Social Deviance scales (e.g., Clinical Scales 4 and 9, ASP) predict substantial variance in the social deviance factor and affiliated subscales of the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996), whereas MMPI-2 measures of affective and interpersonal functioning predict substantial variance in the affective-interpersonal PPI factor. In addition, the results of two regression models indicate that the Restructured Clinical scales provide the most parsimonious assessment of psychopathic personality traits.     

An MCMI-II item-level component analysis: personality and clinical factors

The Millon Clinical Multiaxial Inventory, Version 2 (MCMI-II) was released to replace the MCMI-I. Research into the factor structure of the items of the MCMI-I showed components consistent with the underlying construction theory. No such work has been done with the new MCMI-II. For this study, we analyzed the personality disorder and clinical syndrome items across two subject samples. For 579 Veterans Administration patients and 492 normal college students, six personality factors were identified. The samples shared Hostility, Histrionic/Schizoid, Dependent, Compulsive, and a Sadistic variant. For the clinical syndrome items, eight factors were isolated for veterans and seven for normals. Depression, Alcohol Abuse, Drug Abuse, Crying, and Mania were shared factors. Most of the factors were found to be highly consistent with MCMI-II scale keyings.     

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.     

Convergent validity of alternative MMPI-2 personality disorder scales

The Morey, Waugh, and Blashfield (1985) MMPI (Hathaway et al., 1989) personality disorder scales provided a significant contribution to personality disorder research and assessment. However, the subsequent revisions to the MMPI and the multiple revisions to the diagnostic criteria sets that have since occurred may have justified comparable revisions to these scales. Somwaru and Ben-Porath (1995) selected a substantially different set of items from the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) to assess Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) personality disorder diagnostic criteria. In our study, we compared the convergent validity of these alternative MMPI-2 personality disorder scales with respect to 3 self-report measures of personality disorder symptomatology in a sample of 82 psychiatric outpatients. The results suggested that Somwaru and Ben-Porath's scales are as valid as the original Morey et al. scales and might be even more valid for the assessment of borderline, antisocial, and schizoid personality disorder symptomatology.     

MCMI-II borderline personality disorder in anorexia and bulimia nervosa

The aim of the present study is to explore the MCMI-II personality style and MCMI-II possible disorder of borderline personality (BPD) in various groups of women. 93 patients-31 anorexia nervosa restricting subtype (ANr), 31 anorexia nervosa binge-eating/purging subtype (ANp), and 31 bulimia nervosa purging subtype (BNp); 31 women at high risk for eating disorder or symptomatic control group (S-CG) and 31 without known pathology or not symptomatic control group (NS-CG)-completed the Spanish version of the MCMI-II. The results revealed: (1) clinically significant borderline personality traits [74>Base Rate (BR) <85]: 16.1% ANr, 12.9% ANp, and 45.2% BNp versus 3.2% of the S-CG and none of the NS-CG; (2) possible disorder (BR>84): 29% ANr, 41.9% ANp and 29% BNp. According to the MCM-II, women with BNp displayed more BPD traits than possible disorder (though these were more severe). However, the probability of a possible disorder was higher in ANp (more disorders than traits).     

Convergent validity of the MCMI-III personality disorder scales and the MMPI-2 scales

The MCMI-III personality disorder scales (Millon, 1994) were empirically validated in a sample of prisoners, psychiatric inpatients, and outpatients (N = 477). The scale intercorrelations were congruent with those obtained by Millon, Davis, and Millon (1997). We conclude that our Flemish/Dutch version shows no significant differences with the original version of the MCMI-III as far as intercorrelations are concerned. Convergent validity of the MCMI-III personality disorder scales was evaluated by the correlational data between the MCMI-III personality disorder scales and the MMPI-2 clinical (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) and personality disorder (Somwaru & Ben-Porath, 1995) scales. Improved convergence was obtained compared with previous versions of the MCMI-I. Only the compulsive MCMI-III personality disorder scale remains problematic. The scale even showed negative correlations with some of the related clinical scales and with the corresponding personality disorder scales of the MMPI-2.     

The Levenson Self-Report Psychopathy scale: an examination of the personality traits and disorders associated with the LSRP factors

There are several self-report measures of psychopathy, most of which use a two-factor structure. There is debate regarding the convergence of these factors, particularly with regard to Factor 1 (F1), which is related to the interpersonal and affective aspects of psychopathy; Factor 2 (F2) is related to the social deviance associated with psychopathy. This study examines the relations between the Levenson Self-Report Psychopathy (LSRP) factors and personality traits and disorders (PDs) in an undergraduate sample (n = 271). LSRP Factor 1 is related to an antagonistic interpersonal style (i.e., low Agreeableness; high Narcissistic PD and ratings of prototypical psychopathy), whereas Factor 2 is more strongly related to negative emotionality (i.e., Neuroticism), disinhibition (i.e., low Conscientiousness) and a broad array of PD symptoms. The authors interpret these findings in the context of alternative measures of psychopathy and suggest that the LSRP is a reasonable, albeit imperfect, measure of psychopathy.     

Detection of feigned mental disorders: a meta-analysis of the MMPI-2 and malingering

The validity of test data from multiscale inventories is dependent on self-reports that may be easily distorted by malingering. In examining the Minnesota Multiphasic Personality Inventory-2's (MMPI-2) role in the assessment of feigning, this review provides a conceptual analysis of the detection strategies underlying the MMPI-2 validity scales. The conceptual analysis is augmented by comprehensive meta-analysis of 65 MMPI-2 feigning studies plus 11 MMPI-2 diagnostic studies. For the rare-symptoms strategy, Fp (Cohen's d = 2.02) appears especially effective across diagnostic groups; its cut scores evidence greater consistency than most validity indicators. The data supported the F as an effective scale but questioned the routine use of Fb. Among the specialized scales, Ds appeared especially useful because of its sophisticated strategy, consistent cut score, and minimalfalse-positives. General guidelines are offeredfor specific MMPI-2 validity scales in the assessment of malingering with specific diagnoses.     

DSM-III-R personality disorders and the five-factor model of personality: an empirical comparison.

The relationship between the five-factor model (FFM) of personality and the Diagnostic and Statistical Manual of Mental Disorders (rev. 3rd ed.; DSM-III-R) personality disorders was examined in a sample of 54 psychiatric outpatients. Correlations between raw scores on the NEO-Personality Inventory (NEO-PI) and the number of DSM-III-R personality disorder symptoms rated present using a semistructured interview were computed. In addition, correlations between NEO-PI scores and scores on two self-report personality disorder inventories were also examined to determine which results replicated across instruments. Results indicated that the FFM personality dimensions of Neuroticism, Extraversion, and Agreeableness were most apparent in the DSM-III-R conceptualizations of the personality disorders.     

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.     

The Clinical Utility of the MMPI-2 in Diagnosing Unipolar Depression Among Male Alcoholics

The correspondence between Scale 2 elevations on the MMPI-2 and SCID-diagnosed unipolar depression (major depression and dysthymia) and alcohol-induced depression was evaluated among 106 consecutive male admissions to an inpatient alcohol treatment unit. Valid profiles were obtained from 87 subjects, 15% of whom were diagnosed with unipolar depression and another 4.5% with presumed alcohol-induced depression. The sensitivity of Scale 2 (the probability that a depressed subject would obtain an elevated score) ranged from .19 to .42. Positive predictive power (the probability that a subject who obtained an elevated score had a depressive disorder) ranged from .23 to .38. Neither Scale 2 alone nor Scale 2 paired in 2-point code types predicted the presence or absence of comorbid depressive disorders among male alcoholics.     

Computerized adaptive personality testing: a review and illustration with the MMPI-2 Computerized Adaptive Version

Computerized adaptive testing in personality assessment can improve efficiency by significantly reducing the number of items administered to answer an assessment question. Two approaches have been explored for adaptive testing in computerized personality assessment: item response theory and the countdown method. In this article, the authors review the literature on each and report the results of an investigation designed to explore the utility, in terms of item and time savings, and validity, in terms of correlations with external criterion measures, of an expanded countdown method-based research version of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), the MMPI-2 Computerized Adaptive Version (MMPI-2-CA). Participants were 433 undergraduate college students (170 men and 263 women). Results indicated considerable item savings and corresponding time savings for the adaptive testing modalities compared with a conventional computerized MMPI-2 administration. Furthermore, computerized adaptive administration yielded comparable results to computerized conventional administration of the MMPI-2 in terms of both test scores and their validity. Future directions for computerized adaptive personality testing are discussed.     

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).     

Interpretive dilemmas created by the minnesota multiphasic personality inventory 2 (MMPI-2)

While the new MMPI-2 has the potential to provide more and better clinically relevant information than its predecessor, its introduction also creates several important problems for clinicians and researchers. In particular, the new norms and the use of uniform (rather than linear) T-scores result in the same raw scores on the two tests yielding clinical profiles that can be quite different, both qualitatively and quantitatively. These differences can result in difficulty in MMPI-2 profile interpretation when the user is relying on MMPI interpretive strategies. This paper addresses these concerns and offers some temporary remedial strategies.
