Exploring Potential Ethnic Bias Among MMPI-3 Scales in Assessing Personality Psychopathology

This study examined statistical bias in the measurement of personality psychopathology in the Latinx population using the Minnesota Multiphasic Personality Inventory-3 (MMPI-3). Data were extracted from two studies that yielded a composite data set of 103 White individuals and 250 Latinx individuals. All participants were administered the MMPI-2-Restructured Form-Extended Battery (MMPI-2-RF-EX) or MMPI-3 and the Personality Inventory for the DSM-5 Short Form (PID-5-SF). First, we conducted correlation analyses between theoretically overlapping scales of the PID-5-SF and the MMPI-3 among White and Latinx individuals. The majority of theoretically associated scales were found to be at least moderately associated in the total sample. In addition, Steiger's z-tests indicated that correlations were similar in magnitude across the White and Latinx ethnic groups. Hierarchical regression subsequently determined the presence of slope and/or intercept bias. Only one analysis (the MMPI-3 Anger Proneness prediction of PID-5-SF Negative Affectivity) indicated statistically significant intercept bias. No evidence of slope bias was found. In other words, these analyses indicated that the vast majority of the relationships between MMPI-3 scales and associated personality psychopathology constructs (as measured by the PID-5-SF) remained consistent across both ethnic groups. Overall, the results supported the appropriate cross-cultural use of the MMPI-3 to assess personality psychopathology.

Association between personality profiles and symptomatology patterns based on TCI and MMPI-2-RF in a transdiagnostic psychiatric sample: A person-centered approach

BACKGROUND

The temperament and character dimensions of personality appear to be networking structures that interact nonlinearly. Previous studies have attempted to classify temperament and character subtypes using a person-centered approach but have been unable to explore the relationship between the combination of temperament and character and psychopathology patterns in a transdiagnostic sample. The purpose of this study was to examine how symptomatology patterns differ according to individuals' personality profiles, employing a psychobiological model in a transdiagnostic psychiatric sample.

METHODS

Participants were 1881 patients who visited the psychiatry department of a major medical hospital in Seoul, Korea, and completed both the Temperament Character Inventory (TCI) and the Minnesota Multiphasic Personality Inventory-2-Restructed Form (MMPI-2-RF) as part of their psychological evaluation. We performed two separate latent profile analyses using four temperament and four character indicators of the TCI to identify personality profiles and nine restructured clinical scales of the MMPI-2-RF to identify symptom patterns.

RESULTS

Five personality classes emerged: "vulnerable-maladaptive," "stable-adaptive," "average," "inhibited-neurotic," and "impulsive-irrational." Moreover, six symptom classes emerged: "non-distressed," "depressed," "emotionally-distressed," "average," "dysfunctional thoughts," and "confused." The personality profiles comprising a combination of rigid temperament and immature character were related to patterns of more severe subjective pain and symptoms. However, profiles with less rigid temperament and less immature character exhibited more diverse symptom patterns.

CONCLUSIONS

This study examined the relationship between personality profiles and symptomatology patterns, suggesting that understanding patients' personality profiles may be helpful in predicting symptom manifestation and establishing treatment plans.

An Exploratory Study of MMPI-2-RF Personality and Psychopathology Profiles of Adults with Autism Spectrum Disorder without Intellectual Disability

OBJECTIVE

More empirical research is needed to disentangle the phenotypes of autism spectrum disorder (ASD) and cluster C personality symptomatology (CCPD), as both show similarities in their clinical presentation. We explored personality and psychopathology dimensions as conceptualized in contemporary dimensional taxonomies (i.e., hierarchical taxonomy of psychopathology; HiTOP) in adults with ASD without intellectual disability operationalized by the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF).

METHOD

Applying secondary analytic processes using clinical data, we cross-examined the MMPI-2-RF profiles of adults with ASD (n = 28) compared to adults with Cluster C personality disorders (CCPD; n = 28) and a control group (n = 28) by conducting nonparametric tests and assessing effect sizes.

RESULTS

The profiles of the ASD and CCPD groups evidenced to be similar, and both average clinical profiles diverged from the average control group profiles by elevated levels of demoralization, internalizing, and somatization symptomatology. There were small differences between the average profiles of adults with ASD and adults with CCPD. Additional research using dimensional measures of psychopathology could elucidate the dimensional phenotypes of ASD and CCPD.

CONCLUSIONS

Based on the results in this study, the MMPI-2-RF may not meaningfully discriminate between the two clinical presentations, with the exception of various externalizing scales.

Associations Between MMPI-3 Scale Scores and the DSM-5 AMPD and ICD-11 Dimensional Personality Traits

The current study aimed to examine the associations between Minnesota Multiphasic Personality Inventory-3 (MMPI-3) scales and the dimensional personality traits contained within the ICD-11 Personality Disorder diagnosis and DSM-5 Alternative Model for Personality Disorders (AMPD) models. The sample consisted of 489 undergraduate students, with dimensional personality traits operationalized via the Comprehensive Assessment of Traits relevant to Personality Disorder (CAT-PD). A priori hypotheses were generated for which MMPI-3 scales would be most associated with each personality trait domain, as well as individual CAT-PD scales. Zero-order correlations and regression analyses were used to examine associations between a set of hypothesized MMPI-3 scale scores and CAT-PD scale scores. The results showed a pattern of meaningful correlations supporting the majority of hypotheses. Moreover, most hypothesized scales also incremented one another in regression models predicting hypothesized PD scale scores. These findings indicate that the MMPI-3 is well situated to aid clinicians in the assessment of personality trait dysfunction from a dimensional perspective.

The structure of dimensions of psychopathology in normative and clinical samples: Applying causal discovery to MMPI-2-RF scales to investigate clustering of psychopathology spectra and p-factors

We applied a Bayesian Constraint-based Causal Discovery method (BCCD) to examine the hierarchical structure of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) Restructured Clinical (RC) scales. Two different general psychopathology super spectra (p-factor) scales were extracted from (1) all RC scales and (2) all RC scales except the RCd (Demoralization) scale. These p-factor scales were included in separate models to investigate the structure of dimensions of psychopathology in a normative (n = 3,242) and clinical (n = 2,466) sample, as well as the combined normative/clinical sample (N = 5,708), by applying the BCCD algorithm to obtain a data-driven reconstruction of the internal hierarchical structure of the MMPI-2-RF. Research on the underlying structure of the MMPI-2-RF has clinical relevance as well as conceptual relevance in the context of the HiTOP model. Results demonstrated that the syndromes measured with the RC-scales-in presence of a p-factor-cluster into six spectra: internalizing, disinhibited-externalizing, antagonistic-externalizing, thought disorder, detachment, and somatoform. These results may support a super spectrum construct, as it was necessary for obtaining a bottom-up reconstruction of this six-spectrum structure. We found support for superiority of a broad super spectrum with additional variance over and above demoralization, as it resulted in the clearest structure (i.e., clustering of the RC scales). Furthermore, our results indicate independent support for the bifactor structure model of psychopathology.

Development of the Dimensional Clinical Personality Inventory Antisocial Personality Disorder Scale based on the HiTOP

We aimed to develop a version of the Dimensional Clinical Personality Inventory 2 (IDCP-2) according to the Hierarchical Taxonomy of Psychopathology (HiTOP) for the assessment of antisocial personality disorder traits (i.e., IDCP Antisocial Personality Disorder Scale; IDCP-ASPD), as well as verify its psychometric properties. We developed new factors to cover ASPD traits, and collect data with 206 adults from the community (Mage = 31.3; 77.8% women). Participants completed the IDCP-ASPD, factors from IDCP-2, and Personality Inventory for DSM-5 (PID-5). Exploratory structural equation modeling (E-SEM) suggested a 3 factors solution, grouping the 14 factors composing the IDCP-ASPD. Reliability indicators were good. Correlations between IDCP-ASPD and external measures corroborated expectations. The bootstrap two-sample t-test comparing non-clinical and psychiatric groups suggested good discrimination capacity of the IDCP-ASPD. Favorable evidence was found for the usability of the developed scale for ASPD traits measurement, although future studies must replicate the findings in samples composed by ASPD patients.

Associations between MMPI-3 scale scores and the DSM-5 personality disorders

OBJECTIVE

The current study examined associations between Minnesota Multiphasic Personality Inventory-3 (MMPI-3) scales and self-reported DSM-5 Section II personality disorder (PD) symptoms. A priori hypotheses were generated for which MMPI-3 scales would be most highly associated with each PD.

METHODS

We used a large sample (n = 489) of university students, who completed the MMPI-3 and two established self-report measures of personality disorders.

RESULTS

The results were generally consistent with theoretical expectations and previous research utilizing the MMPI-2-RF. Specifically, most hypothesized MMPI-3 scales exhibited meaningful associations with relevant PD variables, although there were some notable exceptions. The regression models revealed significant predictors for each PD which were generally consistent with expectations and previous research.

CONCLUSIONS

Overall, the MMPI-3 appears well situated to cover a range of DSM-5 Section II PD-related psychopathology, and three of the new MMPI-3 scales appear to have added utility for assessing personality pathology.

The Hierarchical Structure and Predictive Validity of the Personality Inventory for DSM-5 in Chinese Nonclinical Adolescents

To evaluate the factor structure, reliability, and validity of the Personality Inventory for DSM-5 (PID-5) in Chinese nonclinical adolescents, a total of 1,442 Chinese middle school youths (M_age = 14.85, girls = 52.4%) were recruited in the present study. All the participants completed the full-length 220-item PID-5. Some participants (n = 1,003) were administered adolescents' social adjustment as a criterion measure at the same time and 236 participants took part in longitudinal assessment of the PID-5 and adolescents' social adjustment 6 months later. First, exploratory structural equation modeling analyses supported a six-factor structure of the PID-5 in our present sample. Second, Negative Affectivity, Detachment, Antagonistic, and Disinhibition domains had positive correlations with negative social adjustment, and negative correlations with positive social adjustment concurrently and longitudinally, with the exception of Constraint and Psychoticism. Third, Cronbach's alpha for the PID-5 traits ranged from .57 to .91 in the full sample. The 6-month test-retest reliability by indexes of interclass correlation coefficient showed poor to good stability. As a whole, our findings provided preliminary evidence of the PID-5 as a reliable and valid measure of adolescents' maladaptive personality traits in mainland China.

Validity and utility of Hierarchical Taxonomy of Psychopathology (HiTOP): II. Externalizing superspectrum

The Hierarchical Taxonomy of Psychopathology (HiTOP) is an empirical effort to address limitations of traditional mental disorder diagnoses. These include arbitrary boundaries between disorder and normality, disorder co-occurrence in the modal case, heterogeneity of presentation within dis-orders, and instability of diagnosis within patients. This paper reviews the evidence on the validity and utility of the disinhibited externalizing and antagonistic externalizing spectra of HiTOP, which together constitute a broad externalizing superspectrum. These spectra are composed of elements subsumed within a variety of mental disorders described in recent DSM nosologies, including most notably substance use disorders and "Cluster B" personality disorders. The externalizing superspectrum ranges from normative levels of impulse control and self-assertion, to maladaptive disinhibition and antagonism, to extensive polysubstance involvement and personality psychopathology. A rich literature supports the validity of the externalizing superspectrum, and the disinhibited and antagonistic spectra. This evidence encompasses common genetic influences, environmental risk factors, childhood antecedents, cognitive abnormalities, neural alterations, and treatment response. The structure of these validators mirrors the structure of the phenotypic externalizing superspectrum, with some correlates more specific to disinhibited or antagonistic spectra, and others relevant to the entire externalizing superspectrum, underlining the hierarchical structure of the domain. Compared with traditional diagnostic categories, the externalizing superspectrum conceptualization shows improved utility, reliability, explanatory capacity, and clinical applicability. The externalizing superspectrum is one aspect of the general approach to psychopathology offered by HiTOP and can make diagnostic classification more useful in both research and the clinic.

Alternative DSM-5 Model for Personality Disorders Through the Lens of an Empirical Network Model

The Alternative Model for Personality Disorders defined in Diagnostic and Statistical Manual of Mental Disorders-Fifth edition (DSM-5) has recently attracted considerable interest in empirical research, with different hypotheses being proposed to explain the discordant results shown in previous research. Empirical network analysis has begun to be applied for complementing the study of psychopathological phenomena according to a new perspective. This article applies this analysis to personality facets measured in a sample of 626 patients with mental disorders and a 1,034 normative sample, using the Personality Inventory for DSM-5. The results reveal five substructures partially equivalent to domains defined in the DSM-5. Discordant facets (suspiciousness, hostility, rigid perfectionism, attention seeking, and restricted affectivity) play the role of connectors between substructures. Invariance between clinical and community networks was found except for the connection between unusual beliefs and perceptual dysregulation (stronger in the clinical sample). Considering the strength centrality index, anxiousness, emotional lability, and depressivity can be highlighted for their relative importance within both clinical and normative networks.

Psychometric Properties of the Personality Inventory for DSM-5-Brief Form in a Community Sample with High Rates of Trauma Exposure

In the current study, we used a sample of predominantly African-American women with high rates of trauma exposure (N = 434) to examine psychometric properties of the Personality Inventory for DSM-5-Brief Form (PID-5-BF). We compared model fit between a model with five correlated latent factors and a higher-order model in which the five latent factors were used to estimate a single "general pathology" factor. Additionally, we computed estimates of internal consistency and domain interrelations and examined indices of convergent/discriminant validity of the PID-5-BF domains by examining their relations to relevant criterion variables. The expected five-factor structure demonstrated good fit indices in a confirmatory factor analysis, and the more parsimonious, higher-order model was retained. Within this higher-order model, the first-order factors accounted for more variance in the criterion variables than the general pathology factor in most instances. The PID-5-BF domains were highly interrelated (rs = .38 to .66), and convergent/discriminant validity of the domains varied: Negative Affectivity and Detachment generally showed the hypothesized pattern of relations with external criteria, while Antagonism and Disinhibition displayed less consistent and discriminant relations. Results are discussed in terms of the costs and benefits of using brief pathological trait measures in samples characterized by high levels of psychopathology.

Assessing DSM-5 Section II Personality Disorders Using the MMPI-2-RF in an Iranian Community Sample

The aim of the current study was to examine the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008) scales in assessing Diagnostic and Statistical Manual of Mental Disorders-Fifth edition (DSM-5) Section II Personality Disorder (PD) symptoms. For this purpose, we first tested the cross-cultural factorial and criterion validity of MMPI-2-RF scales. We used a sample of 536 (327 women and 209 men) community individuals in Tehran, Iran. DSM-5 Section II PD criterion counts were assessed using the Structured Clinical Interview for DSM-5-Screening Personality Questionnaire. Exploratory structural equation modelling analyses revealed that the models reported by Ben-Porath and Tellegen generally fitted the data well. Criterion validity of the MMPI-2-RF scales as well as MMPI-2-RF PDs spectra scales were analyzed with respect to their correlations with DSM-5 Section II PDs, indicating results generally consistent with expectations. Results based on Poisson or Negative binomial regression models indicated that a set of MMPI-2-RF scale hypotheses were supported, with several exceptions that are discussed in detail. These findings have implications for applicability of the MMPI-2-RF across Iranian population.

Assessing ICD-11 personality trait domain qualifiers with the MMPI-2-RF

OBJECTIVE

The current study examined the utility of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) in assessing ICD-11 personality psychopathology trait domain qualifiers.

METHOD

Using a community sample (N = 217) weighted for externalizing dysfunction, this study evaluated the convergence between ICD-11 trait domains as measured by the personality inventory for DSM-5 (PID-5) with hypothesized MMPI-2-RF scales. Particular emphasis was placed on evaluating the convergence between the ICD-11 trait domain qualifiers and the MMPI-2-RF personality psychopathology-5 (PSY-5) scales, as the latter are meant to represent broadband domains of personality pathology.

RESULTS

Correlation and regression analyses demonstrated expected associations between ICD-11 domains and conceptually expected MMPI-2-RF scales, with some minor exceptions. Notably, the Anankastia domain showed associations with scales assessing negative affect, but did not show expected negative associations with scales related to disinhibition.

CONCLUSIONS

The findings generally supported the use of the MMPI-2-RF in assessing individual expressions of personality dysfunction from the ICD-11 trait domain qualifier perspective.

Construct validity of Minnesota Multiphasic Personality Inventory-2-Restructured Form scale scores in correctional settings

Limited research has examined the link between Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) scales and contemporary personality and psychopathology models within correctional settings. This study focused on establishing construct validity of the MMPI-2-RF in offender samples from a broad personality framework. Two samples of incarcerated men and women completed a battery of broadband personality measures and narrowband measures that capture conceptually related constructs. To examine how MMPI-2-RF scale scores and criterion measures converged in a conjoint latent structure, we conducted a series of exploratory structural equation modelling analyses, which revealed factors similar to those of extant hierarchical personality models. At the broadband level, four factors (Positive Activation, Negative Affectivity, Inhibition and Agreeableness) were observed, whereas narrowband criteria yielded five factors (Behavioural Approach System, Disinhibition/Externalizing, Danger/Thrill Seeking, Self-Assurance/Boldness, and Unemotionality/Coldheartedness). MMPI-2-RF scale scores converged with the personality/psychopathology models in a theoretically expected manner. Limitations and directions for future research are discussed. © 2020 John Wiley & Sons, Ltd.

Further Examining the Construct Validity of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) Personality Disorder Spectra Scales

The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) Personality Disorder (PD) Spectra scales reflect a recent effort to dimensionally measure Diagnostic and Statistical Manual of Mental Disorders-5-based personality disorders. Initial studies generally support the sound psychometric properties of most scales, although the need to continue cross-validating and expanding the known empirical correlates of these scales remains. The goal of the current investigation was to replicate and extend previous research on MMPI-2-RF PD Spectra scale scores and further examine their construct validity. Using a sample of 765 undergraduate students (69.3% female; M_age = 19.95; 73.3% White), zero-order correlations between scores on MMPI-2-RF PD Spectra scales and measures of personality and psychopathology variables were calculated. Median convergent and discriminant correlations were compared using Fisher's r-to-z tests. Results indicated that hypothesized convergent associations were meaningfully stronger in magnitude than hypothesized discriminant ones, with exceptions to scales measuring Obsessive-Compulsive, Narcissistic, and Paranoid PDs. Findings generally supported the construct validity of MMPI-2-RF PD Spectra scale scores. Implications for clinical practice and research, methodological limitations, and suggestions for future research are discussed.

Comparing the Prediction of Dimensional Personality Disorders (PID-5) After Three Personality Trait Models

Abstract. A dimensional approach for Personality Disorders was proposed in the DSM-5. To assess this approach, a new instrument (the Personality Inventory for DSM-5 [PID-5]) was developed in 2012. One research line has analyzed its convergent validity with personality traits, focusing almost exclusively on the Five-Factor Model (FFM). However, previous evidence about the relationships between Categorical Personality Disorders and other personality trait models shows that they can improve our understanding of Personality Disorders beyond the FFM. The aim of the present study is to compare the power of three personality models (FFM, Cloninger’s, and Zuckerman’s) to predict PID-5 domains. Three samples from the Spanish and Catalan general population were collected for this study depending on which personality questionnaire was applied (1,052 for revised NEO Personality Inventory [NEO-PI-R], 465 for Zuckerman-Kuhlman-Aluja Personality Questionnaire [ZKA-PQ], and 332 for Temperament and Character Inventory Revised [TCI-R-140]). The PID-5 was also applied to all subjects. Factor and regression results indicate that the three models were able to predict Dimensional Personality Disorders well, although some differences emerge between them. Specific relationships between dimensional disorders and traits, the role of the facets as well as the utility of the results reported are discussed.

Validity and utility of Hierarchical Taxonomy of Psychopathology (HiTOP): I. Psychosis superspectrum

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a scientific effort to address shortcomings of traditional mental disorder diagnoses, which suffer from arbitrary boundaries between psychopathology and normality, frequent disorder co-occurrence, heterogeneity within disorders, and diagnostic instability. This paper synthesizes evidence on the validity and utility of the thought disorder and detachment spectra of HiTOP. These spectra are composed of symptoms and maladaptive traits currently subsumed within schizophrenia, other psychotic disorders, and schizotypal, paranoid and schizoid personality disorders. Thought disorder ranges from normal reality testing, to maladaptive trait psychoticism, to hallucinations and delusions. Detachment ranges from introversion, to maladaptive detachment, to blunted affect and avolition. Extensive evidence supports the validity of thought disorder and detachment spectra, as each spectrum reflects common genetics, environmental risk factors, childhood antecedents, cognitive abnormalities, neural alterations, biomarkers, and treatment response. Some of these characteristics are specific to one spectrum and others are shared, suggesting the existence of an overarching psychosis superspectrum. Further research is needed to extend this model, such as clarifying whether mania and dissociation belong to thought disorder, and explicating processes that drive development of the spectra and their subdimensions. Compared to traditional diagnoses, the thought disorder and detachment spectra demonstrated substantially improved utility: greater reliability, larger explanatory and predictive power, and higher acceptability to clinicians. Validated measures are available to implement the system in practice. The more informative, reliable and valid characterization of psychosis-related psychopathology offered by HiTOP can make diagnosis more useful for research and clinical care.

Personality traits across the psychosis spectrum: A Hierarchical Taxonomy of Psychopathology conceptualization of clinical symptomatology

Psychotic disorders have varied clinical presentations, diagnostic stability is poor and other mental disorders often co-occur with the conditions. To improve the clinical and pathophysiological utility of classification systems for psychosis, it is necessary to consider how symptoms may reflect dimensions of psychopathology that extend beyond the boundaries of traditional diagnostic classifications. We examined personality deviation as a means for explaining symptom variation across individuals with serious mental illness. Participants (N = 312) with psychosis, first-degree biological relatives and healthy controls underwent comprehensive clinical evaluations that included symptom ratings and Diagnostic Statistical Manual consensus diagnoses. They completed the Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (PID-5), which provides multidimensional assessment of personality disturbances and characterizes psychosis-relevant phenomena, and the Schizotypal Personality Questionnaire (SPQ), a widely accepted measure of schizotypal traits. PID-5 was comparable with SPQ in differentiating between participants with and without psychosis. Greater psychotic symptomatology and higher scores on the SPQ Cognitive-perceptual dimension were associated with higher scores on PID-5 Psychoticism. Facet-level traits showed diverse associations with existing clinical syndromes, suggesting they have utility for quantifying separable symptom dimensions that cut across existing disorders. Yet the patient groups were similar across four of the five PID-5 personality trait domains, indicating shared patterns of personality expression that challenge existing categorical delineations. © 2019 John Wiley & Sons, Ltd.

Clinical Utility of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) in a Residential Treatment Program for Homeless Individuals

The current study examined the clinical utility of the Restructured Form of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2-RF) in a residential treatment program for homeless individuals. MMPI-2-RF scale scores from 146 participants with valid profiles were correlated with variables obtained at intake and during treatment. The sample was then followed 12 months postdischarge to test preregistered hypotheses regarding MMPI-2-RF predictors of hospital readmissions. The results indicated that a variety of MMPI-2-RF scale scores were correlated with historical and diagnostic variables at intake and with measures of treatment outcome, including behavioral problems and successful outcome. A broad range of MMPI-2-RF scale scores were related to readmissions postdischarge and many of these relationships remained significant when tested in Poisson regression models containing other predictors. However, the postdischarge findings were generally inconsistent with our predictions and were of small effect size. The clinical implications of MMPI-2-RF results for residential treatment programs are discussed.

Personality Inventory for DSM-5 (PID-5): cross-cultural adaptation and content validity in the Brazilian context

Abstract Objective To describe the process of cross-cultural adaptation of the Personality Inventory for DSM-5 (PID-5) to the Brazilian context. Methods Cross-cultural adaptation involved the steps of independent translation of the instrument, synthesis version, and back-translation. Analysis of content validity was conducted by a multidisciplinary expert committee and consisted of quantitative assessment of agreement indicators. The test was then applied to a target population. Results All the steps required for a cross-cultural adaptation were followed and satisfactory agreement values (≥ 4.75) were reached for most of the structures assessed. Most of the changes suggested by the experts were followed; these changes consisted primarily of adjustments to verb tense and agreement and the inclusion of letters and words to allow gender inflection. In the pre-test, no suggestions were made and the instrument was considered comprehensible. Conclusion The Brazilian version of the PID-5 was found to be adequate to the Brazilian context from semantic, idiomatic, cultural, and conceptual perspectives. The Brazilian version assessed here can be freely used, was approved by the publishers who hold the copyright on the instrument, and is considered the official version of the instrument. New studies are underway to determine the validity and reliability of the PID-5.

A Brief but Comprehensive Review of Research on the Alternative DSM-5 Model for Personality Disorders

PURPOSE OF REVIEW

Both the Alternative DSM-5 Model for Personality Disorders (AMPD) and the chapter on personality disorders (PD) in the recent version of ICD-11 embody a shift from a categorical to a dimensional paradigm for the classification of PD. We describe these new models, summarize available measures, and provide a comprehensive review of research on the AMPD.

RECENT FINDINGS

A total of 237 publications on severity (criterion A) and maladaptive traits (criterion B) of the AMPD indicate (a) acceptable interrater reliability, (b) largely consistent latent structures, (c) substantial convergence with a range of theoretically and clinically relevant external measures, and (d) some evidence for incremental validity when controlling for categorical PD diagnoses. However, measures of criterion A and B are highly correlated, which poses conceptual challenges. The AMPD has stimulated extensive research with promising findings. We highlight open questions and provide recommendations for future research.

Personality Inventory for DSM-5-Short Form (PID-5-SF): Reliability, Factorial Structure, and Relationship With Functional Impairment in Dual Diagnosis Patients

Section III of the Diagnostic and Statistical Manual of Mental Disorders-Fifth edition (DSM-5) has generated a personality paradigm consisting of 25 personality facets identified in five domains. The developed assessment instrument Personality Inventory for DSM-5 (PID-5) has showed good psychometric properties, but the potential for certain improvements still remain. In this article, a sample of 282 dual diagnosis patients is used to provide evidence of the psychometric properties of the PID-5-Short Form. The mean value of Cronbach's alpha coefficients reached .73 on the facets and .84 for domains and test-retest values ranged between .57 to .83 for facets and .70 to .87 for the domains. Confirmatory factor analyses conducted showed good fit on both models tested: the five correlated factor structure and hierarchical structure of personality traits. The WHODAS 2.0 domains of understanding and communicating, and participating in society, appear to show the strongest relationship with personality facets. In general, the PID-5-Short Form shows adequate psychometric properties for use in dual diagnosis patients.

The MMPI-2-Restructured Form (MMPI-2-RF): Assessment of Personality and Psychopathology in the Twenty-First Century

This article describes the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) and situates the instrument in contemporary psychopathology and personality literature. The historical evolution of the MMPI instruments is highlighted, including how failure to update the test for several decades resulted in increasing disinterest by basic researchers and how the restructuring efforts beginning in the 2000s promised to realign the instrument with basic research. In this regard, the construct validity associated with MMPI-2-RF scores in the context of contemporary dimensional models of psychopathology is considered. Research supporting the applied utility of the MMPI-2-RF scales in a variety of contexts-including mental health screenings, presurgical evaluations, forensic assessment, and public safety screening-is also reviewed. Critiques of the MMPI-2-RF are described and addressed. Finally, a series of recommendations for future updates of the MMPI-2-RF are described along with a path toward the MMPI-3.

Investigating the Relationship Between DSM-5 Personality Disorder Domains and Facets and Aggression in an Offender Population Using the Personality Inventory for the DSM-5

This study explored associations between aggression and the Personality Inventory for the DSM-5 (PID-5) domains and facets in 208 male offenders. Regression analyses revealed no significant domain-level relationships using either the APA-three facets only (Krueger, Derringer, Markon, Watson, & Skodol, 2013) or the Krueger, Derringer, Markon, Watson, and Skodol (2012) scoring algorithms. The PID-5 facets of Hostility and Risk Taking were significantly associated with aggression. These findings highlight the importance of a facet-level analysis when exploring the PD-aggression relationship. The authors call attention to how this knowledge can contribute to clinical-forensic practice and note limitations associated with using only PID-5 domain-level scoring approaches. More research is required to determine whether a universally accepted scoring approach can be adopted and promoted alongside future versions of the PID-5.

Personality Traits and Weight Loss Surgery Outcome

PURPOSE OF THE REVIEW

To update the recent findings on the influence of personality features on postoperative weight loss in patients undergoing bariatric surgery.

RECENT FINDINGS

Several studies investigated the influence of pre-surgical psychological variables on the outcome of bariatric surgery, but the effective role of personality factors (i.e., both normal personality traits and personality disturbances) in shaping bariatric surgery outcome is still unclear. We analyzed nine recent papers that examined the impact of pre-operative personality traits on postoperative weight loss among individuals undergoing surgery for severe obesity. A personality pattern denoting the ability to self-regulate in spite of the urges or demands of the moment emerged as a robust predictor of good outcome across studies, independently from baseline psychiatric comorbidity and personality disorders.

The Role of Dimensional Personality Psychopathology in a Forensic Inpatient Psychiatric Setting

The Minnesota Multiphasic Personality Inventory-2 Restructured Form is a widely used measure of psychopathology and includes the Personality Psychopathology Five (PSY-5) scales, which measure dimensional maladaptive personality traits similar to those in the DSM-5 alternative model for personality disorder (PD) diagnosis. The current study evaluated the role of these dimensional personality psychopathology characteristics in a sample of 1,110 inpatients in a forensic psychiatric setting, where personality psychopathology plays a significant but understudied role. The authors examined the extent to which dimensional personality psychopathology characteristics (as measured by the PSY-5) were associated with borderline and antisocial PD diagnoses and institutional aggression. Results support the usefulness of measuring dimensional personality traits for understanding PD diagnoses, as well as incidents of institutional aggression. More specifically, the PSY-5 scales appear to measure the core features of borderline and antisocial PDs. This study supports the inclusion of dimensional personality assessment in understanding aggressive behavior in inpatient settings.

Could Time Detect a Faking-Good Attitude? A Study With the MMPI-2-RF

Background and Purpose: Research on the relationship between response latency (RL) and faking in self-administered testing scenarios have generated contradictory findings. We explored this relationship further, aiming to add further insight into the reliability of self-report measures. We compared RLs and T-scores on the MMPI-2-RF (validity and restructured clinical [RC] scales) in four experimental groups. Our hypotheses were that: the Fake-Good Speeded group would obtain a different completion time; show higher RLs than the Honesty Speeded Group in the validity scales; show higher T-Scores in the L-r and K-r scales and lower T-scores in the F-r and RC scales; and show higher levels of tension and fatigue. Finally, the impact of the speeded condition in malingering was assessed.

Materials and Methods: The sample was comprised of 135 subjects (M = 26.64; SD = 1.88 years old), all of whom were graduates (having completed at least 17 years of instruction), male, and Caucasian. Subjects were randomly assigned to four groups: Honesty Speeded, Fake-Good Speeded, Honesty Un-Speeded, and Fake-Good Un-Speeded. A software version of the MMPI-2-RF and Visual Analog Scale (VAS) were administered. To test the hypotheses, MANOVAs and binomial logistic regressions were run.

Results: Significant differences were found between the four groups, and particularly between the Honest and Fake-Good groups in terms of test completion time and the L-r and K-r scales. The speeded condition increased T-scores in the L-r and K-r scales but decreased T-scores in some of the RC scales. The Fake groups also scored higher on the VAS Tension subscale. Completion times for the first and second parts of the MMPI-2-RF and T-scores for the K-r scale seemed to predict malingering.

Conclusion: The speeded condition seemed to bring out the malingerers. Limitations include the sample size and gender bias.

Using Bayesian regression to test hypotheses about relationships between parameters and covariates in cognitive models

An important tool in the advancement of cognitive science are quantitative models that represent different cognitive variables in terms of model parameters. To evaluate such models, their parameters are typically tested for relationships with behavioral and physiological variables that are thought to reflect specific cognitive processes. However, many models do not come equipped with the statistical framework needed to relate model parameters to covariates. Instead, researchers often revert to classifying participants into groups depending on their values on the covariates, and subsequently comparing the estimated model parameters between these groups. Here we develop a comprehensive solution to the covariate problem in the form of a Bayesian regression framework. Our framework can be easily added to existing cognitive models and allows researchers to quantify the evidential support for relationships between covariates and model parameters using Bayes factors. Moreover, we present a simulation study that demonstrates the superiority of the Bayesian regression framework to the conventional classification-based approach.

Introduction to the Special Section: Linking the MMPI-2-RF to Contemporary Models of Psychopathology

This special section considers 9 independent articles that seek to link the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/ 2011 ) to contemporary models of psychopathology. Sellbom ( this issue ) maps the Specific Problems scales onto hierarchical psychopathology structures, whereas Romero, Toorabally, Burchett, Tarescavage, and Glassmire ( this issue ) and Shkalim, Almagor, and Ben-Porath ( this issue ) show evidence of linking the instruments' scales to diagnostic representations of common higher order psychopathology constructs. McCord, Achee, Cannon, Harrop, and Poynter ( this issue ) link the MMPI-2-RF scales to psychophysiological constructs inspired by the National Institute of Mental Health (NIMH) Research Domain Criteria. Sellbom and Smith ( this issue ) find support for MMPI-2-RF scale hypotheses in covering personality psychopathology in general, whereas Klein Haneveld, Kamphuis, Smid, and Forbey ( this issue ) and Kutchen et al. ( this issue ) demonstrate the utility of the MMPI-2-RF in capturing contemporary conceptualizations of the psychopathic personality. Finally, Franz, Harrop, and McCord ( this issue ) and Rogers et al. ( this issue ) mapped the MMPI-2-RF scales onto more specific transdiagnostic constructs reflecting interpersonal functioning and suicide behavior proneness, respectively.

The Validity and Clinical Utility of the Personality Inventory for DSM-5 Response Inconsistency Scale

The Personality Inventory for DSM-5 (PID-5; Krueger, Derringer, Markon, Watson, & Skodol, 2012) is a self-report instrument designed to assess the personality traits of the alternative model of personality disorders (AMPD) in Section III of the DSM-5. Despite its relatively recent introduction to the field, the instrument is frequently and widely used. One criticism of this instrument is that it does not include validity scales to detect potentially invalidating response style, including noncredible over- and underreporting and inconsistent (random) responding. Keeley, Webb, Peterson, Roussin, and Flanagan (2016) constructed an inconsistency scale (the PID-5-INC) to assess random responding on PID-5 and proposed a number of potential cut scores that could be applied. In this study, we attempted to cross-validate the PID-5-INC, including whether the scale could detect randomly generated protocols and distinguish them from nonrandom protocols produced by two student and two clinical samples. The PID-5-INC successfully distinguished random from nonrandom protocols and the best cut scores were similar to those reported by Keeley et al. (2016). We also found that a relatively low amount of random responding compromised the psychometric validity of the PID-5 trait scales, which extended previous work on this instrument.

Applicability of Item Mapping in Rating the Severity of Pathological Personality Traits

Abstract The aim of this study was to investigate the combined use of two pathological personality tests, the Dimensional Clinical Personality Inventory (IDCP) and the Personality Inventory for DSM-5 (PID-5), within the context of incremental validity in order to verify the increasing severity of the constructs used. We generated item maps for sets of items based on three dimensions of IDCP and five facets of PID-5, selected according to the possibility of pairing between scales. The study included 642 individuals, predominantly women aged over 18, divided into three groups according to the dimensions and facets. There was an increase in the level of severity, typically related to the different personality disorders, in addition to the complementation between instruments, providing incremental validity. The use of item mapping helped us understand the increasing severity of the traits, and allowed the verification of the clinical relevance of the constructs.

Examination of DSM-5 Section III avoidant personality disorder in a community sample

The current research evaluated the continuity between DSM-5 Section II and Section III diagnostic operationalizations of avoidant personality disorder (AvPD). More specifically, the study had three aims: (1) to examine which personality constructs comprise the optimal trait constellation for AvPD; (2) to investigate the utility of the proposed structure of the Section III AvPD diagnosis, in regard to combining functional impairment (criterion A) and a dimensional measure of personality (criterion B) variables; and (3) to determine whether AvPD-specific impairment confers incremental meaningful contribution above and beyond general impairment in personality functioning. A mixed sample of 402 university and community participants was recruited, and they were administered multiple measures of Section II PD, personality traits, and personality impairment. A latent measurement model approach was used to analyse data. Results supported the general continuity between Section II and Section III of the DSM-5; however, three of the four main criterion B traits were the stronger predictors. There was also some support for the trait unassertiveness augmenting the criterion B trait profile. The combination of using functional impairment criteria (criterion A) and dimensional personality constructs (criterion B) in operationalizing AvPD was supported; however, the reliance of disorder-specific over general impairment for criterion A was not supported.

Self-report indicators of negative valence constructs within the research domain criteria (RDoC): A critical review

BACKGROUND

In 2010, the National Institute of Mental Health (NIMH) created the Research Domain Criteria (RDoC), a research framework for integrating multiple units of information to explicate basic dimensions of functioning underlying both adaptive and maladaptive behavior. Our goal in this review is to evaluate self-report indicators of negative valence systems constructs within RDoC.

METHODS

We review the content and correlates of several of the most popular self-report measures currently classified within the negative valence systems in the RDoC matrix, using both our own data and previously published results. We use these data to evaluate whether these measures are appropriately placed; in addition, wherever possible, we recommend better alternatives to assess key RDoC constructs.

RESULTS

Our findings indicate that many of the currently listed self-report measures are misplaced. Specifically, our data reveal that some of the purported fear scales are better conceptualized as measures of anxiety and/or anxious arousal. In addition, none of the currently listed measures of frustrative nonreward is a clear, unambiguous indicator of that construct.

LIMITATIONS

The RDoC matrix currently does not list any specific measures of either loss or sustained threat, which makes it difficult to identify appropriate measures of these constructs. In many cases, the specificity/discriminant validity of proposed measures remains uncertain.

CONCLUSIONS

Researchers wanting to include self-report measures of negative valence constructs currently receive little guidance from the RDoC matrix. Future assessment work should be oriented toward the development of measures that are explicitly designed to assess these RDoC constructs.

Utility of the Personality Inventory for DSM-5-Brief Form (PID-5-BF) in the Measurement of Maladaptive Personality and Psychopathology

The Diagnostic and Statistical Manual of Mental Disorders-Fifth edition ( DSM-5) Personality and Personality Disorders workgroup developed the Personality Inventory for the DSM-5 (PID-5) for the assessment of the alternative trait model for DSM-5. Along with this measure, the American Psychiatric Association published an abbreviated version, the PID-5-Brief form (PID-5-BF). Although this measure is available on the DSM-5 website for use, only two studies have evaluated its psychometric properties and validity and no studies have examined the U.S. version of this measure. The current study evaluated the reliability, factor structure, and construct validity of PID-5-BF scale scores. This included an evaluation of the scales' associations with Section II PDs, a well-validated dimensional measure of personality psychopathology, and broad externalizing and internalizing psychopathology measures. We found support for the reliability of PID-5-BF scales as well as for the factor structure of the measure. Furthermore, a series of correlation and regression analyses showed conceptually expected associations between PID-5-BF and external criterion variables. Finally, we compared the correlations with external criterion measures to those of the full-length PID-5 and PID-5-Short form. Intraclass correlation analyses revealed a comparable pattern of correlations across all three measures, thereby supporting the use of the PID-5-BF as a screening measure of dimensional maladaptive personality traits.

Assessment of DSM-5 Section II Personality Disorders With the MMPI-2-RF in a Nonclinical Sample

The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008 / 2011 ) is frequently used in clinical practice. However, there has been a dearth of literature on how well this instrument can assess symptoms associated with personality disorders (PDs). This investigation examined a range of hypothesized MMPI-2-RF scales in predicting PD symptoms. We evaluated these associations in a sample of 397 university students who had been administered the MMPI-2-RF and the Structured Clinical Interview for DSM-IV Axis II Disorders-Personality Questionnaire (First, Gibbon, Spitzer, Williams, & Benjamin, 1997 ). Zero-order correlation analyses and negative binomial regression models indicated that a wide range of MMPI-2-RF scale hypotheses were supported; however, the least support was available for predicting schizoid and obsessive-compulsive PDs. Implications for MMPI-2-RF interpretation and PD diagnosis are discussed.

White matter correlates of psychosis-linked traits support continuity between personality and psychopathology

The link between diagnoses of psychotic disorders and attenuated white matter connectivity is well established, but little is known about the degree to which similar white matter differences predict traits linked to psychosis-proneness in the general population. Moreover, intelligence is too rarely considered as a covariate in neural endophenotype studies, despite its known protective role against psychopathology in general and its associations with broad aspects of neural structure and function. To determine whether psychosis-linked personality traits are linearly associated with white matter microstructure, we examined white matter correlates of Psychoticism, Absorption, and Openness to Experience in a large community sample, covarying for sex, age, and IQ. Findings support our hypothesis that the white matter correlates of the shared variance of these traits overlap substantially with the frontal lobe white matter connectivity patterns characteristic of psychotic spectrum disorders. These findings provide biological support for the notion that liability to psychosis is distributed throughout the population, is evident in brain structure, and manifests as normal personality variation at subclinical levels.

[Validation of a French translation of Krueger's personality inventory for DSM-5 in its brief form (PID-5 BF)]

OBJECTIVE

Since the publication of the DSM-5 (APA, 2013), the dimensional conception of the personality disorders is co-existing with the classical categorical paradigm. Tools have been proposed for the evaluations of five big pathological factors to be explored further according to the APA (negative affectivity, detachment, antagonism, disinhibition, psychoticism). Despite numerous works using these questionnaires (30 works in 3 years according to Al-Adjani et al., 2015), none of them have yet been translated into French. Also, the main objective of the paper is to present a French translation of the Personality Inventory for DSM -5 by Kruegger et al. (2013) in its brief form of 25 items (PID-5 BF).

METHOD

To reach this goal, we have employed the classic translation-retranslation method (Vallerand, 1989) and tested the consistence and the validity of this French version among a non-clinical sample (n=216) of young adults (age=31.4, SD=4.8), in joining some other questionnaires in their short forms to study the external validity of the PID-5 about the psychological distress (SCL-10, Nguyen, 1983), the categorical diagnosis of personality disorders (SAPAS, Moran et al., 2003) and the classical Big Five dimensions of the personality (BDI 10, Ramamstedt and John, 2007). The internal consistency of this translation has been studied through the classical outcomes on factor analysis for the dimensional repartitions of the items in 5 scales and Cronbach's alpha for the consistency of each found dimensions. The external validity has been explored by studying Pearson's correlations between the outcomes on each dimension of the PID-5 BF and both the clinical dimensions of SCL-10, personality dimensions of the BFI-10 or personality disorders (SAPAS).

RESULTS

Factor analysis led to the same repartition of the 25 items as the original versions. Each of the dimensions is consistent enough (α>.65) to be taken into account as clinically significant. The items of the French version of the PID-5 BF follow the expected repartitions in 5 dimensions, which are consistent enough. Although their mean scores are significantly not different from the outcomes found by Krueger with the PID-5 200 items among another non-clinical population (n=264), one cannot say that is enough to ensure the external validity of our translation, for it uses neither the same tools nor sample. A comparison with a French translation of the PID-5 would be more significant. However, the external validity of the French version seems to be significant enough. Global score on the PID-5 is correlated both to the Global Severity Index of the SCL-10, which reflects global psychological distress, and SAPAS's score, which evaluates the suspicion of personality disorder. The clinical validity of the PID-5 is confirmed by the relationships between negative affectivity and anxiety or depression or antagonism and hostility, although the clinical scale of the SCL-10, with one item by dimension, is less sensitive than the complete original version in 90 items (DeRogatis, 1974). PID-5 score and domains are also correlated with the Big Five personality dimension and global score of personality disorders which led us to think that it is coherent with the evaluation of personality suffering (r=.34) and dimensions. The links between negative affectivity and neurosism (r=.48) or between desinhibition and extraversion (r=.32) or the negative correlation between psychoticism and conscientiousness (r=-0.16) are consistent with the expectations related both to the descriptions of the domains by the DSM and outcomes on the comparisons between PID-5 200 item scales and NEO-PI or BFI 45 items.

DISCUSSION

This translation offers enough consistency and validity to be used in future studies. This could lead us to either continue studying a more representative general population or testing its validity in focusing on a clinical sample where personality disorders are prevalent, such as homeless men or substance users. As soon as a French version of the PID-5 200 items is published, one can compare the outcomes on PID-5 BF and PID-5 to lead to estimations of personality disorders and pathological domains among French populations and explore personality disorders throughout a dimensional paradigm instead of syndromic perspective. One can also see whether the items that have been kept for each dimension are as saturated in the French version as in the original one. Among general populations, comparisons with clinical distress, syndromic personality disorders or dimensional aspect of personality could be done with complete versions of PID-5, Symptom Check-list, Personality Disorders Questionnaires or Big Five Inventory; therefore, the brief forms of any questionnaire could be used among any people whose psychological distress or side effects impaired their attention and concentration.

Mapping the MMPI-2-RF Specific Problems Scales Onto Extant Psychopathology Structures

A main objective in developing the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008 ) was to link the hierarchical structure of the instrument's scales to contemporary psychopathology and personality models for greater enhancement of construct validity. Initial evidence published with the Restructured Clinical scales has indicated promising results in that the higher order structure of these measures maps onto those reported in the extant psychopathology literature. This study focused on evaluating the internal structure of the Specific Problems and Interest scales, which have not yet been examined in this manner. Two large, mixed-gender outpatient and correctional samples were used. Exploratory factor analyses revealed consistent evidence for a 4-factor structure representing somatization, negative affect, externalizing, and social detachment. Convergent and discriminant validity analyses in the outpatient sample yielded a pattern of results consistent with expectations. These findings add further evidence to indicate that the MMPI-2-RF hierarchy of scales map onto extant psychopathology literature, and also add support to the notion that somatization and detachment should be considered important higher order domains in the psychopathology literature.
