Personality: individual differences and clinical assessment

The Big Five personality factors and psychological well-being following stroke: a systematic review

PURPOSE

To identify and appraise studies investigating the relationship between the Big Five personality factors and psychological well-being following stroke and evidence for personality change.

METHODS

Systematic searches of six databases (PsychINFO, CINAHL, Ovid Medline, Cochrane, PubMed, and Web of Science) were conducted from inception to June 2017. Studies involving adult stroke samples that employed a validated measure of at least one of the Big Five personality factors were included. Two reviewers independently assessed the eligibility and methodological quality of studies.

RESULTS

Eleven studies were identified that assessed associations between personality and psychological well-being after stroke (nine studies) or post-stroke personality change (two studies). A consistent finding was that higher neuroticism was significantly related to poorer psychological well-being. The evidence for the other Big Five factors was mixed. In terms of personality change, two cross-sectional studies reported high rates of elevated neuroticism (38-48%) and low extraversion (33-40%) relative to normative data. Different questionnaires and approaches to measuring personality (i.e., self vs. informant ratings, premorbid personality vs. current personality) complicated comparisons between studies.

CONCLUSIONS

People high on neuroticism are at increased risk of poor psychological well-being after stroke. Prospective longitudinal studies are needed to address the limited research on post-stroke personality change. Implications for rehabilitation High neuroticism is associated with poorer psychological well-being after stroke. Assessing personality characteristics early after stroke may help to identify those at risk of poor psychological outcomes.

On the Incremental Validity of MMPI-2 Psychopathology-5 Scales over the Revised Neo Personality Inventory Scales for Predicting Personality Disorders

The hypothesis that the MMPI-2 Psychopathology-5 scales are better predictors of personality disorders than the Revised NEO Personality Inventory scales was tested using Personality Adjective Checklist personality disorder scales with a 9-point response format, The three inventories were completed by 258 introductory psychology students (113 men and 145 women) for partial course credit. Hierarchical multiple regression analysis was performed for predicting each Personality Adjective Checklist scale by entering the Revised NEO Personality Inventory scales as a set in the first step and the Psychopathology-5 scales as a set in the second step. Incremental validity of the Psychopathology-5 scales over the Revised NEO Personality Inventory scales for predicting each Personality Adjective Checklist scale was measured by the R2 change at the end of the second step in the hierarchical multiple regression analysis. Incremental validity values ranged from .01 to .09, with a median of .03, and were significant for only five Personality Adjective Checklist scales. Such results provided very little support for the hypothesis of relative superiority of the Psychopathology-5 scales over the Revised NEO Personality Inventory domain scales for predicting personality disorders.

Beyond the Big Five: New Directions for Personality Research and Practice in Organizations

Industrial and organizational personality researchers and practitioners contend with ever-changing requirements of the workplace, and therefore, it is important to reevaluate and innovate with respect to useful organizational research. Much research evidence documents the importance of personality variables in determining behavior and performance in work settings, yet further advances in understanding and predicting work outcomes will depend upon more sophisticated taxonomic structures of personality, better criterion constructs and measurement, and different validation strategies. We describe the logic, strengths, and weaknesses of four taxonomic approaches to the structure of personality—the Five-Factor Model, HEXACO model, circumplex models, and nomological-web clustering—and how each limits or facilitates future developments in theory and practice. We describe how improved measurement and modeling approaches to personality, along with advances in synthetic validation efforts, will enable greater accuracy in our theories, hypotheses, and prediction of work outcomes.

Clinical psychological and neuropsychological issues with left ventricular assist devices (LVADs)

BACKGROUND

Left ventricular assist devices (LVADs) are increasingly being used to treat patients in end-stage heart failure (HF) as bridge-to-transplantation, lifetime support or destination therapy. However, the importance of this newer technique for chronic cardiac support compared to heart transplantation is still open to discussion. To date, there are few studies that extensively explore the psychological and cognitive profiles of patient with ventricular assist devices (VADs).

METHODS

We studied the psychological aspects, quality of life (QOL) and cognitive profiles of 19 patients with HF before VAD implantation and then at two, five and 16 months post-implantation.

RESULTS

Our results showed that after VAD implantation, patients did not show any psychopathological problems such as anxiety and/or depression. More interestingly, despite the constant risk of neurological events determined by the continuous-blood-flow pump (CBFP), patients' cognitive functioning did not worsen. In fact, significant enhancements were observed over time.

CONCLUSIONS

Psychological and cognitive deficits are common in advanced HF and often worsen over time. Appropriately designed and randomized studies are needed to demonstrate whether earlier VAD implantation is warranted to arrest cognitive decline and encourage better post-implantation adaptation.

The MMPI-2-RF Personality Psychopathology Five (PSY-5-RF) scales: development and validity research

This article describes the development, internal psychometric, and external validation studies on scales designed to measure the Personality Psychopathology Five (PSY-5) from MMPI-2 Restructured Form (MMPI-2-RF) items. Diverse and comprehensive data sets, representing various clinical and nonclinical populations, were classified into development and validation research samples. Item selection, retention, and exclusion procedures are detailed. The final set of PSY-5-RF scales contain 104 items, with no item overlap between scales (same as the original MMPI-2 PSY-5 scales), and no item overlap with the Demoralization scale. Internal consistency estimates are comparable to the longer MMPI-2 PSY-5 scales. Appropriate convergent and discriminant validity findings utilizing various self-report, collateral rating, and record review data are reported and discussed. A particular emphasis is offered for the unique aspects of the PSY-5 model: psychoticism and disconstraint. The findings are connected to the broader PSY-5 literature and the recommended review of systems (Harkness, Reynolds, & Lilienfeld, this issue) presented in this series of articles.

Gender differences in personality patterns and smoking status after a smoking cessation treatment

BACKGROUND

The lack of conclusive results and the scarce use of the Millon Clinical Multiaxial Inventory-III (MCMI-III) in the study of the relationship between smoking and personality are the reasons that motivated the study reported here. The aim of the present study was to analyze the influence of personality patterns, assessed with the MCMI-III, and of nicotine dependence on treatment outcomes at the end of the treatment and at 12 months follow-up in men and women smokers receiving cognitive-behavioral treatment for smoking cessation.

METHODS

The sample was made up of 288 smokers who received cognitive-behavioral treatment for smoking cessation. Personality patterns were assessed with the Millon Clinical Multiaxial Inventory-III (MCMI-III). Abstinence at the end of the treatment and at 12-month follow-up was validated with the test for carbon monoxide in expired air.

RESULTS

The results showed significant differences by personality patterns that predict nicotine dependence (Narcissistic and Antisocial in men and Schizoid in women). At the end of the treatment it is more likely that quit smoking males with a Compulsive pattern and less likely in those scoring high in Depressive, Antisocial, Sadistic, Negativistic, Masochistic, Schizotypal and Borderline. In women, it is less likely that quit smoking those with the Schizoid pattern. At 12 months follow-up it is more likely that continue abstinent those males with a high score in the Compulsive pattern. Furthermore, nicotine dependence was an important variable for predicting outcome at the end of the treatment and smoking status at 12 months follow-up in both men and women.

CONCLUSIONS

We found substantial differences by gender in some personality patterns in a sample of smokers who received cognitive-behavioral treatment for smoking cessation. We should consider the existence of different personality patterns in men and women who seek treatment for smoking cessation.

The location of trait emotional intelligence in personality factor space

The construct of trait emotional intelligence (trait EI or trait emotional self-efficacy) provides a comprehensive operationalization of emotion-related self-perceptions and dispositions. In the first part of the present study (N=274, 92 males), we performed two joint factor analyses to determine the location of trait EI in Eysenckian and Big Five factor space. The results showed that trait EI is a compound personality construct located at the lower levels of the two taxonomies. In the second part of the study, we performed six two-step hierarchical regressions to investigate the incremental validity of trait EI in predicting, over and above the Giant Three and Big Five personality dimensions, six distinct criteria (life satisfaction, rumination, two adaptive and two maladaptive coping styles). Trait EI incrementally predicted four criteria over the Giant Three and five criteria over the Big Five. The discussion addresses common questions about the operationalization of emotional intelligence as a personality trait.

Comparability of scores on the MMPI-2-RF scales generated with the MMPI-2 and MMPI-2-RF booklets

In most validity studies on the recently released 338-item MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008; Tellegen & Ben-Porath, 2008), scale scores were derived from the 567-item MMPI-2 booklet. In this study, we evaluated the comparability of the MMPI-2-RF scale scores derived from the original 567-item MMPI-2 booklet with MMPI-2-RF scale scores derived from the 338-item MMPI-2-RF booklet in a Dutch student sample (N = 107). We used a counterbalanced (ABBA) design. We compared results with those previously reported by Tellegen and Ben-Porath (2008). Our findings support the comparability of the scores of the 338-item version and the 567-item version of the 50 MMPI-2-RF scales. We discuss clinical implications and directions for further research.

Update on the debate about the existence and utility of the Big Five: a ten-year follow-up on Carroll's "the Five-Factor Personality Model: how complete and satisfactory is it?

This paper is a follow-up comment on John B. Carroll's critique of the Big Five Model and his suggestion years ago on how to design and conduct research properly on the structure of personality and its assessment. The status of research on personality factor models is discussed, and conclusions are reached regarding the likely consequences and further prospects of the failure of personality theorists and practitioners to follow through on Carroll's poignant suggestion for required effort.

The validity and utility of the positive presentation management and negative presentation management scales for the Revised NEO Personality Inventory

Schinka, Kinder, and Kremer developed "validity" scales for the Revised NEO Personality Inventory (NEO PI-R; Costa & McCrae) to detect underreporting-the Positive Presentation Management (PPM) Scale and overreporting-the Negative Presentation Management (NPM) Scale. In this investigation, the clinical utility of these scales was examined using the established validity scales from the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher et al.) as the referent. The sample was composed of 370 psychiatric patients who completed the NEO PI-R and the MMPI-2 as part of a routine evaluation. Results indicated that response distortion compromised the utility of the NEO PI-R domain scales. Moreover, the PPM and NPM scales and an NPM-PPM index significantly differentiated invalid under-and overreporting groups from a valid responding group. The PPM and NPM-PPM index were adequate in classifying under- and overreporters, respectively.

Impulsivity, aggressiveness, and DSM-IV personality disorders

The aim of this study is to assess whether impulsive and aggressive traits can be placed on a continuum with DSM-IV Cluster B Personality Disorders (PDs) and to determine if different aspects of these personality traits are specifically associated with individual Cluster B PDs. The study group comprised 461 outpatients admitted consecutively to a clinic that specializes in the diagnosis and treatment of PDs. Principal component analyses clearly suggested a five-factor structure of both normal and psychopathological personality traits. Importantly, measures of impulsivity, aggressiveness and novelty seeking formed a part of the principal component that clustered all Cluster B PDs. Regression analyses indicated that impulsive traits were selectively associated with Borderline PD whereas different aspects of aggressiveness were useful in discriminating Narcissistic PD from Antisocial PD. Sensation seeking traits formed a part of Histrionic PD. These results indicate that impulsive/aggressive traits may be useful in explaining both why Cluster B PDs tend to covary, and why they frequently differ in clinical pictures and courses.

Cerebral information processing in personality disorders: I. Intensity dependence of auditory evoked potentials

Patients with personality disorders such as the histrionic type exaggerate their responses when receiving external social or environmental stimuli. We speculated that they might also show an augmenting pattern of the auditory evoked potential N1-P2 component in response to stimuli with increasing levels of intensity, a response pattern that is thought to be inversely correlated with cerebral serotonin (5-HT) activity. To test this hypothesis, we collected auditory evoked potentials in 191 patients with personality disorders (19 patients with the paranoid type, 12 schizoid, 14 schizotypal, 18 antisocial, 15 borderline, 13 histrionic, 17 narcissistic, 25 avoidant, 30 dependent and 28 obsessive-compulsive) and 26 healthy volunteers. Their personality traits were measured using the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ). Compared with healthy subjects and other patient groups, the histrionic group scored higher on the basic traits Affective Instability, Stimulus Seeking, Rejection and Narcissism, and on the higher traits Emotional Dysregulation and Dissocial, than the other groups, and the schizoid group scored lower on most of the DAPP-BQ basic and higher traits. In addition, the histrionic group showed steeper amplitude/stimulus intensity function (ASF) slopes at three midline scalp electrodes than the healthy controls or the other patient groups. The ASF slopes were not correlated with any DAPP-BQ traits in the total sample of 217 subjects. However, the DAPP-BQ basic trait Rejection was positively correlated with the ASF slopes at all three electrode sites in the histrionic group. The increased intensity dependence of the auditory N1-P2 component might indicate that cerebral 5-HT neuronal activity is, on average, weak in the histrionic patients.

Correlates of the MMPI–2 Restructured Clinical (RC) Scales in a College Counseling Setting

We designed this study to identify empirical correlates on the MMPI-2 (Butcher et al., 2001) restructured clinical (RC) scales in a college counseling setting with a sample of 228 men and 522 women from a university-based psychological clinic. Participants were administered the MMPI-2 at intake and were rated by their therapists on a variety of variables including a 192-item Client Description Form. The findings indicate that the RC scales were generally most strongly correlated with conceptually relevant criteria and generally uncorrelated with conceptually nonrelevant criteria, which replicated findings of convergent and discriminant validity from previous studies. Follow-up analyses indicate that the RC scales have improved discriminant validity in comparison to the clinical scales and stronger convergent validity than a set of alternative MMPI-2 measures.

Assessment of the five-factor model of personality

The five-factor model (FFM) of personality is obtaining construct validation, recognition, and practical consideration across a broad domain of fields, including clinical psychology, industrial-organizational psychology, and health psychology. As a result, an array of instruments have been developed and existing instruments are being modified to assess the FFM. In this article, we present an overview and critique of five such instruments (the Goldberg Big Five Markers, the revised NEO Personality Inventory, the Interpersonal Adjective Scales-Big Five, the Personality Psychopathology-Five, and the Hogan Personality Inventory), focusing in particular on their representation of the lexical FFM and their practical application.

On Construct Validity: Issues of Method and Measurement

Fifty years ago, L. J. Cronbach and P. E. Meehl (1955) advocated for the concept of construct validity, noting that psychologists study hypothetical, inferred entities and that validating measures of such entities involves basic theory testing. Three important developments in clinical assessment following that seminal article are noteworthy. First, clinical research has benefited from greater theoretical integration and subsequent differentiation among related constructs. Second, implementation of ongoing, critical evaluation of all aspects of the construct validity process, including theory development, hypothesis specification, research design, and empirical evaluation, has improved clinical assessment. Third, improvement in evaluating fit between hypotheses and observations has been sought. Improved means of evaluating multitrait, multimethod designs, and ways to increase their clinical representativeness, are one encouraging development. Ongoing efforts to improve the construct validity process reflect the legacy of L. J. Cronbach and P. E. Meehl.

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.

Socially desirable responding and the factorial stability of the NEO PI-R

The goal of the present investigation is to compare the factor structure of the revised NEO Personality Inventory (NEO PI-R; P. T. Costa & R. R. McCrae, 1992) in samples of respondents differentially motivated to respond in a socially desirable manner. In the French sample, the authors compared the NEO PI-R structure of job applicants (N=12,631) subgrouped by relative degree of socially desirable responding with that of a normative sample (N=801). In the Belgian sample, the authors compared the NEO PI-R structure in naturally occurring groups, including job applicants (N=3,028), individuals receiving career counseling (N=221), and a normative sample (N=549). Results indicate that the NEO PI-R factor structure remained stable across all samples.

Cortical excitability in cocaine-dependent patients: a replication and extension of TMS findings

Cortical excitability can be assessed by transcranial magnetic stimulation (TMS). Previously we observed that TMS motor threshold (MT) was elevated in abstinent cocaine-dependent subjects. In the current study we aimed at replicating our initial finding, exploring other TMS-based measures of excitability, and examining association with personality characteristics. Nineteen cocaine-dependent and 12 healthy control subjects were examined. Resting and activated motor thresholds (RMT and AMT) and duration of the cortical silent period (CSP) were examined. The Cocaine Experience Questionnaire (CEQ) was administered to assess cocaine-induced psychotic symptoms. The relationship between Minnesota Multiphasic Personality Inventory (MMPI) scales and cortical excitability measures was also examined. AMT was significantly elevated in cocaine-dependent subjects on both hemispheres. RMT was also significantly elevated on the right hemisphere. No CSP changes were noted. Patients with cocaine-induced paranoia had longer CSPs on the right hemisphere compared to subjects reporting no paranoid experiences. The patients displayed significantly elevated scores on several MMPI scales, though the scale scores did not correlate with cortical excitability measures. These data support our initial finding of decreased cortical excitability in abstinent cocaine-dependent subjects. We interpret this finding as a compensatory mechanism against the stimulating and epileptogenic effects of cocaine.

Personality architecture: within-person structures and processes

This chapter reviews theory and research on intraindividual personality structures and processes. Principles for modeling the architecture of personality, that is, the overall design and operating characteristics of intraindividual personality systems, are addressed. Research demonstrates that a focus on within-person structures and processes advances the understanding of two aspects of personality coherence: the functional relations among distinct elements of personality, and cross-situational coherence in personality functioning that results from interactions among enduring knowledge structures and dynamic appraisal processes. Also reviewed are recent conceptual and empirical advances, which demonstrate that the interindividual personality variables that summarize variability in the population are wholly insufficient for modeling intraindividual personality architecture.

Symptom Correlates of MMPI-2 Scales and Code Types in a Private-Practice Setting

The purpose of this study was to determine empirical symptom correlates of MMPI-2 (Butcher et al., 2001) scales for private-practice clients, a very understudied yet important population. We examined the scores of 240 male and 407 female clients on the Clinical scales, Content scales, Supplementary scales, and frequently occurring code types. We used a factor analyzed version of the Adult Clinical scales of the Multiaxial Diagnostic Inventory (Doverspike, 1990) as a criterion measure. The results generally indicated that the symptom correlates for the MMPI-2 scales and code types were quite similar to those that have been previously reported in other outpatient and inpatient settings. We concluded that descriptors of MMPI-2 scales and code types generated in other settings may be used when interpreting MMPI-2 profiles of private-practice clients.

Uncertainty of data, fuzzy membership functions, and multilayer perceptrons

Probability that a crisp logical rule applied to imprecise input data is true may be computed using fuzzy membership function (MF). All reasonable assumptions about input uncertainty distributions lead to MFs of sigmoidal shape. Convolution of several inputs with uniform uncertainty leads to bell-shaped Gaussian-like uncertainty functions. Relations between input uncertainties and fuzzy rules are systematically explored and several new types of MFs discovered. Multilayered perceptron (MLP) networks are shown to be a particular implementation of hierarchical sets of fuzzy threshold logic rules based on sigmoidal MFs. They are equivalent to crisp logical networks applied to input data with uncertainty. Leaving fuzziness on the input side makes the networks or the rule systems easier to understand. Practical applications of these ideas are presented for analysis of questionnaire data and gene expression data.

A Consideration of Challenges to Psychological Assessment Instruments Used in Forensic Settings: Rorschach As Exemplar

In this brief primer, we provide an outline of key issues that will help psychologists organize and prepare their expert testimony. These issues include the need to obtain essential sources of research, a review of the actual legal standards regarding admissibility of test data in expert testimony, the nature of the expert relative to the assessment instrument in expert testimony, the nature of legal versus scientific debate, and the examination of appropriate qualifications of expertise when offering legal testimony. In addition, we use a summary of information contained in several recent articles to address challenges directed against forensic psychological testing. We use the empirical literature on the Rorschach as an exemplar in discussing these issues, as the admissibility of the Rorschach in particular has been challenged, and the issues frequently focused on with the Rorschach are equally applicable to other psychological measures. In this article, we provide essential sources of Rorschach research regarding several empirical studies that summarize important information and directly address previous criticisms of the measure.

General mental ability in the world of work: occupational attainment and job performance

The psychological construct of general mental ability (GMA), introduced by C. Spearman (1904) nearly 100 years ago, has enjoyed a resurgence of interest and attention in recent decades. This article presents the research evidence that GMA predicts both occupational level attained and performance within one's chosen occupation and does so better than any other ability, trait, or disposition and better than job experience. The sizes of these relationships with GMA are also larger than most found in psychological research. Evidence is presented that weighted combinations of specific aptitudes tailored to individual jobs do not predict job performance better than GMA alone, disconfirming specific aptitude theory. A theory of job performance is described that explicates the central role of GMA in the world of work. These findings support Spearman's proposition that GMA is of critical importance in human affairs.

Methodological Issues in Cross-Cultural and Multicultural Rorschach Research

Hermann Rorschach researched the utility of his inkblot experiment to understand psychopathology and cultural differences. Contemporary research with the Rorschach has evaluated its utility as a test, although it may more properly represent a clinical method with somewhat different evaluation criteria. Recent controversy regarding the adequacy of the Rorschach as a test and the adequacy of its normative data has at times distorted and oversimplified important methodological issues inherent in the study of cultural difference. Cultural processes remain a central and inadequately examined variable in Rorschach research; an important emergent area of inquiry is the Rorschach's clinical utility as a cross-cultural assessment instrument. We review multicultural and cross-cultural methodological issues intrinsic to contemporary Rorschach research here. Consideration of cultural issues enlarges and enriches the Rorschach clinical utility debate and suggests underexplored research strategies that can contribute to its resolution.

Use of the MMPI-2 with Asian populations

Psychological tests developed in the United States are being widely adapted into other languages and cultures around the world. This article examines the generalizability and utility of personality assessment instruments across cultures and addresses methodological issues related to using personality questionnaires in countries different from the one in which they were developed. This article specifically highlights the application of objective psychological tests in Asia with special emphasis on the most widely used and internationally adapted personality instrument, the Minnesota Multiphasic Personality Inventory--2 (MMPI-2). Effective strategies for translating, adapting, and standardizing questionnaires in languages and cultures different from their country of origin are reviewed. The history of several successful adaptations of the original MMPI and MMPI-2 is surveyed to illustrate the extensive research base for the test in Asia. Current research is summarized, and recommendations for future research are provided.

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.

Personality disorder symptoms in adolescence: a five-factor model perspective

The five-factor model has been widely used to describe adaptive and maladaptive functioning in adulthood. However, less is known about the structure and developmental antecedents of personality pathology and personality disorders. In the present study, we examined the validity of the most recent DSM-IV predictions (Widiger, Trull, Clarkin, Sanderson, & Costa, 2002) in a sample of 419 non-clinical adolescents and explored the validity of the unique FFM facetvariances (using the NEO PI-R) to predict disorder symptoms (using the ADP-IV). Our results demonstrate a largely similar correlation and regression pattern between adult and adolescent data, indicating that adaptive and maladaptive trait-descriptive systems relate across a more extended developmental span than has been demonstrated before.

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.

Personality and psychopathology: working toward the bigger picture

There are systematic and meaningful links among normal and abnormal personality traits and Axis I and II constructs from the DSM. Nevertheless, much research in this area focuses on pairs of constructs (e.g., the link between personality traits and a specific Axis I disorder), rather than on the broader multivariate structure of the personality-psychopathology domain. We underscore the need for this broader perspective, a perspective that would transcend largely artificial boundaries between current constructs (e.g., normal and abnormal personality). We outline our approach to research from this perspective and we emphasize the internalizing (mood and anxiety) and externalizing (substance use and antisocial behavior) spectra as promising foci for initial research on the joint structure of personality and psychopathology.

Empirical evaluation of the MCMI-III personality disorder scales

The MCMI-III personality disorder scales were empirically validated with a sample of 870 clinical patients and inmates. Prevalence rates of personality disorders were in general lower on the MCMI-III than clinical ratings, but trait prevalence was generally higher; thus a base rate of 75 on the MCMI-III could be a guideline in the screening of trait prevalence. However, the sensitivity of some MCMI-III scales was very low. Moreover, the correlations of most personality disorder scales of the MCMI-III were significant and positive with corresponding measures on clinical ratings and MMPI-2 personality disorder scales, but these were, in general, not significantly higher than some other correlations. As a consequence the discriminant validity seems to be questionable. The MCMI-III alone cannot be used as a diagnostic inventory, but the test could be useful as a screening device as a part of a multimethod approach that allows aggregation over measures in making diagnostic decisions.

Combining the Rorschach test and the Temperament Character Inventory: a new perspective on personality assessment

BACKGROUND

The numerous reports on research involving the clinical assessment of personality in axis I disorders highlight the importance of temperament features in the current approach to all mental disorders. However, the available instruments of personality assessment have many limits. Self-administered questionnaires depend on the patient's insight, and projective instruments (i.e. the Rorschach test) often lack objectivity. This study compared the results of personality assessment with the Temperament and Character Inventory (TCI) and the Rorschach test to verify their validity.

PATIENTS AND METHODS

TCI and Rorschach tests were administered to a wide sample of patients (n = 180) in a short period. The most common Rorschach siglatures were correlated with the TCI raw scores using the Pearson correlation test.

RESULTS

All TCI temperament dimensions and facets displayed at least two correlations with Rorschach siglatures. The description of each dimension and facet of the TCI obtained with the interpretation of Rorschach siglatures was consistent with its original meaning.

CONCLUSIONS

The TCI and Rorschach tests adequately validated each other. In the future, the administration and integration of these tests will overcome the biases of both. Further, the theoretical bases of the TCI could facilitate the study of psychological functions, whereas the psychodynamic bases of the Rorschach test provide an in-depth insight into temperament traits.

The Representation of Four Personality Disorders by the Schedule for Nonadaptive and Adaptive Personality Dimensional Model of Personality

This study examined the relationships of the Schedule for Nonadaptive and Adaptive Personality (SNAP) model of personality to 4 targeted personality disorders (PDs) in a large multisite sample of patients. Data were examined from 529 patients, who were assigned 1 of 5 primary diagnoses: borderline, schizotypal, avoidant, and obsessive-compulsive PDs and major depression without PD. Patients were administered the SNAP questionnaire and results were compared among diagnostic groups and between patient groups and nonclinical norms. Results indicated that the dimensions of the model appear to have considerable promise in differentiating normal from abnormal personality, particularly in the propensity of individuals with PDs to manifest negative affects and interpersonal detachment. Furthermore, the model appeared to successfully distinguish specific PDs, a property that represents a particular challenge for dimensional models of personality.

Positive Impression Management and Its Influence on the Revised NEO Personality Inventory: A Comparison of Analog and Differential Prevalence Group Designs

Participants (n = 22) completed the Revised NEO Personality Inventory (NEO PI-R) as part of an authentic job application. Protocols produced by this group were compared with "analog" participants (n = 23) who completed the NEO PI-R under standard instructions and again under instructions designed to mimic the test-taking scenario of the job applicants (the "fake-good" condition). Participants completing the NEO PI-R under fake-good instructions and the job applicants scored lower on the Neuroticism and higher on the Extraversion scales than did the participants responding under standard instructions. Analog participants in the fake-good condition scored higher on the Extraversion and lower on the Agreeableness scales than did the job applicants. These results suggest that outcomes from analog designs are generalizable to real-world samples where response dissimulation is probable.

Substance or style? An investigation of the NEO-PI-R validity scales

The Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992b) has been criticized for the absence of validity scales designed to detect response distortion. Recently, validity scales were developed from the items of the NEO-PI-R (Schinka, Kinder, & Kremer, 1997) and several studies have used a variety of methods to test their use. However, it is controversial whether these scales are measuring something that is substantive (such as psychopathology or its absence) or stylistic (which might be effortful distortion or less conscious processes such as lack of insight). In this study, we used a multimethod-multitrait approach to examine the validity of these scales in a clinical sample of 668 participants diagnosed with personality disorders or major depression. Using various indicators of both stylistic and substantive variance, confirmatory factor analyses (CFA) suggested that these validity scales measure something that may be conceptually distinct from, yet highly related to, substantive variance in responding.

A comparative study of the dimensions and facets of the five-factor model in the diagnosis of cases of personality disorder

Two national samples of psychologists (n = 92, n = 89) rated personality disorder cases using either the five factors (domains) or the 30 facets of the five-factor model (FFM) to examine reliability and clinical utility of the model when used as a diagnostic tool. The cases were prototypic and nonprototypic cases representing the three clusters of personality disorders in the DSM-IV. Although confidence was higher using the factors rather than the facets to rate the cases, interrater reliability was similar and the facets were rated more useful for professional communication, case conceptualization, and treatment. Mean ratings for the prototypic cases supported the theorized relationships between those personality disorders and the FFM. Principal components factor analysis of the facet ratings largely replicated the structure of the FFM with only a few facets failing to load with their superordinate dimension in the model. Implications for use of the FFM with personality disorder are discussed.

A quantitative review of the comprehensiveness of the five-factor model in relation to popular personality inventories

Reports of associations between the five-factor model (FFM) and the scales of popular personality inventories have generated controversy regarding the comprehensiveness of the FFM. The controversy is fueled by a preoccupation with capturing scale variance and differentiating between specific scales, whereas the focus should instead be on whether the FFM captures the common variance and the dimensions that exist in personality constructs. Analyses of published data revealed that the portions of scale variance captured by the FFM (mean = 38%) were substantial when evaluated in relation to the portions of common variance that exist in most personality inventories (mean = 50%). Furthermore, interbattery factor analyses indicated that the factor structures in most personality inventories can be closely replicated using data derived solely from scale associations with the FFM. Exceptions to this finding occurred for only 2 of 28 personality inventories. The findings support the comprehensiveness of the FFM.
