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.

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.

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.

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.

Arabic Version of the Personality Inventory for the DSM-5 (PID-5) in a Community Sample of United Arab Emirates Nationals

Background:

Section III of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) proposes a model for conceptualizing personality disorders in which they are characterized by impairments in personality functioning and maladaptive personality traits. The Personality Inventory for DSM-5 (PID-5) is a self-report measure that assesses the presence and severity of these maladaptive personality traits.

Objective:

The current study examined the reliability and validity of the Arabic version of the Personality Inventory for DSM-5 (PID-5) to measure maladaptive personality traits in the Emirati population of the United Arab Emirates.

Methods:

The Arabic version of the PID-5 was administered to a community sample of 1,090 United Arab Emirates nationals (89.5% female and 10.5% male, mean age = 22.44 years old). The descriptive measures, internal consistency, test-retest reliability, convergent validity with NEO – Five Factor Inventory, as well as PID-5’s factor structure, were all addressed.

Results:

The PID-5facets and domains mean scores were higher in the Emirati sample compared to the original US sample. Internal consistency of the PID-5 scales was acceptable to high and test-retest coefficients ranged from 0.84 (facets) to 0.87 (domains). As expected, the five domains of the Arabic version of the PID-5 correlated significantly with all Five-Factor Model domains of personality. Additionally, the Arabic version of the PID-5 confirmed a five-factor structure that resembles the PID-5 domains.

Conclusion:

The findings of this study provided initial support for the use of the Arabic version of the PID-5 to assess maladaptive personality traits in the Emirati population of the United Arab Emirates.

The role of maladaptive personality domains across multiple levels of the HiTOP structure

This study aimed to examine associations between maladaptive personality traits and psychopathology from the perspective of the hierarchical taxonomy of psychopathology (HiTOP). We tested hierarchical structural models to further validate a portion of the structural components of HiTOP. We also tested a priori personality and psychopathology associations with three levels of the HiTOP hierarchy: general psychopathology, spectra and syndromes/disorders. We used a large sample from the general Australian population who completed a large set of personality and psychopathology inventories online. Confirmatory factor analyses indicated that internalizing, externalizing and thought dysfunction spectra emerged structurally, as expected per HiTOP, but also revealed that obsessive-compulsive disorder loaded on both internalizing and thought dysfunction and attention deficit hyperactivity disorder on both externalizing and internalizing. Furthermore, results indicated that almost all personality and psychopathology hypotheses were supported, although trait antagonism did not predict externalizing to the degree initially expected. Implications for personality and psychopathology are discussed. © 2019 John Wiley & Sons, Ltd.

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 DSM-5 Trait Measure in a Psychiatric Sample of Late Adolescents and Emerging Adults: Structure, Reliability, and Validity

The inclusion of a dimensional trait model of personality pathology in DSM-5 creates new opportunities for research on developmental antecedents of personality pathology. The traits of this model can be measured with the Personality Inventory for DSM-5 (PID-5), initially developed for adults, but also demonstrating validity in adolescents. The present study adds to the growing body of literature on the psychometrics of the PID-5, by examining its structure, validity, and reliability in 187 psychiatric-referred late adolescents and emerging adults. PID-5, Big Five Inventory, and Kidscreen self-reports were provided, and 88 non-clinical matched controls completed the PID-5. Results confirm the PID-5's five-factor structure, indicate adequate psychometric properties, and underscore the construct and criterion validity, showing meaningful associations with adaptive traits and quality of life. Results are discussed in terms of the PID-5's applicability in vulnerable populations who are going through important developmental transition phases, such as the step towards early adulthood.

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.

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.

Deriving ICD-11 personality disorder domains from dsm-5 traits: initial attempt to harmonize two diagnostic systems

OBJECTIVE

The personality disorder domains proposed for the ICD-11 comprise Negative Affectivity, Detachment, Dissociality, Disinhibition, and Anankastia, which are reasonably concordant with the higher-order trait domains in the Alternative DSM-5 Model for Personality Disorders.

METHOD

We examined (i) whether designated DSM-5 trait facets can be used to describe the proposed ICD-11 trait domains, and (ii) how these ICD-11 trait features are hierarchically organized. A mixed Danish derivation sample (N = 1541) of 615 psychiatric out-patients and 925 community participants along with a US replication sample (N = 637) completed the Personality Inventory for DSM-5 (PID-5). Sixteen PID-5 traits were designated to cover features of the ICD-11 trait domains.

RESULTS

Exploratory structural equation modeling (ESEM) analyzes showed that the designated traits were meaningfully organized in the proposed ICD-11 five-domain structure as well as other recognizable higher-order models of personality and psychopathology. Model fits revealed that the five proposed ICD-11 personality disorder domains were satisfactorily resembled, and replicated in the independent US sample.

CONCLUSION

The proposed ICD-11 personality disorder domains can be accurately described using designated traits from the DSM-5 personality trait system. A scoring algorithm for the ICD-11 personality disorder domains is provided in appendix.

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.

Personality disorders in DSM-5: emerging research on the alternative model

The current categorical classification of personality disorders, originally introduced in the Diagnostic and Statistical Manual of Mental Disorders (DSM-III), has been found to suffer from numerous shortcomings that hamper its usefulness for research and for clinical application. The Personality and Personality Disorders Work Group for DSM-5 was charged with developing an alternative model that would address many of these concerns. The developed model involved a hybrid dimensional/categorical model that represented personality disorders as combinations of core impairments in personality functioning with specific configurations of problematic personality traits. The Board of Trustees of the American Psychiatric Association did not accept the Task Force recommendation to implement this novel approach, and thus this alternative model was included in Sect. III of the DSM-5 among concepts requiring additional study. This review provides an overview of the emerging research on this alternative model, addressing each of the primary components of the model.

Clinical utility of the DSM-5 alternative model of personality disorders: six cases from practice

In Section III, Emerging Measures and Models, DSM-5 presents an Alternative Model of Personality Disorders, which is an empirically based model of personality pathology measured with the Level of Personality Functioning Scale (LPFS) and the Personality Inventory for DSM-5 (PID-5). These novel instruments assess level of personality impairment and pathological traits. Objective. A number of studies have supported the psychometric qualities of the LPFS and the PID-5, but the utility of these instruments in clinical assessment and treatment has not been extensively evaluated. The goal of this study was to evaluate the clinical utility of this alternative model of personality disorders. Method. We administered the LPFS and the PID-5 to psychiatric outpatients diagnosed with personality disorders and other nonpsychotic disorders. The personality profiles of six characteristic patients were inspected (involving a comparison of presenting problems, history, and diagnoses) and used to formulate treatment considerations. We also considered 6 specific personality disorder types that could be derived from the profiles as defined in the DSM-5 Section III criteria. Results. Using the LPFS and PID-5, we were able to characterize the 6 cases in a meaningful and useful manner with regard to understanding and treatment of the individual patient and to match the cases with 6 relevant personality disorder types. Implications for ease of use, communication, and psychotherapy are discussed. Conclusion. Our evaluation generally supported the utility for clinical purposes of the Alternative Model for Personality Disorders in Section III of the DSM-5, although it also identified some areas for refinement.

Elucidating the Construct Validity of the Psychopathic Personality Inventory Triarchic Scales

This study sought to replicate and extend Hall and colleagues' (2014) work on developing and validating scales from the Psychopathic Personality Inventory (PPI) to index the triarchic psychopathy constructs of boldness, meanness, and disinhibition. This study also extended Hall et al.'s initial findings by including the PPI Revised (PPI-R). A community sample (n = 240) weighted toward subclinical psychopathy traits and a male prison sample (n = 160) were used for this study. Results indicated that PPI-Boldness, PPI-Meanness, and PPI-Disinhibition converged with other psychopathy, personality, and behavioral criteria in ways conceptually expected from the perspective of the triarchic psychopathy model, including showing very strong convergent and discriminant validity with their Triarchic Psychopathy Measure counterparts. These findings further enhance the utility of the PPI and PPI-R in measuring these constructs.
