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. [ABSTRACT FROM AUTHOR]

The Minnesota Multiphasic Personality Inventory-3 (MMPI-3) scales that are designed to assess various forms of externalizing psychopathology have received relatively little research attention to date. The goal of this investigation was therefore to examine the validity of these MMPI-3 scales in the measurement of the externalizing spectrum. A community sample ( n  = 206) with high levels of externalizing psychopathology and a university sample ( n  = 645) were used. The former sample was administered structured clinical interviews for various forms of externalizing psychopathology, whereas the student sample completed the Externalizing Spectrum Inventory-160. Confirmatory factor analysis was used to operationalize the externalizing spectrum using each set of measures. The results indicated that the externalizing MMPI-3 scales were associated with a general externalizing factor and an expected pattern of associations, while systematic residuals of individual disorder symptoms also emerged. Moreover, in the university sample, specific MMPI-3 scales hypothesized to assess antagonistic-externalizing (Aggressiveness, Aggression, and Cynicism) emerged as key predictors of a callous-aggression residual group factor. The Substance Abuse scale was unsurprisingly the best predictor of such dysfunction. These findings provide guidance for mental health practitioners who use the MMPI-3 for the assessment of externalizing psychopathology symptoms., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: M.S. is a paid consultant to the University of Minnesota Press, publisher of the MMPI-3.

The current investigation was designed to examine the impact of underreporting response bias on the Multidimensional Personality Questionnaire (MPQ) and the utility of the Unlikely Virtues scale in detecting such responding. Study participants were randomly assigned to either the underreporting ( n = 100) or standard instruction ( n = 224) conditions. All participants first completed a series of extratest measures under standard instruction prior to the MPQ administration. The results showed that individuals in the underreporting condition scored significantly higher on MPQ scales that reflect positive emotionality and self-control and lower on scales that indicate negative emotionality compared to those in the standard instruction. Moreover, the psychometric validity of MPQ scale scores against extratest measures was substantially attenuated in the underreporting condition compared to the standard instruction condition. The Unlikely Virtues scale differentiated between the conditions at a large effect size magnitude (Hedges' g = 1.21) and showed promising classification accuracy though lower cut scores than those reported in the MPQ manual performed substantially better with respect to sensitivity. Future research needs to replicate these findings in more naturalistic settings with other research designs. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Psychopathic personality disorder (PPD) is a widely recognized disorder that has been associated with high levels of dysfunction across clinical, forensic, occupational, and social settings. The psychopathy construct displays robust connections to social and interpersonal dysfunction; however, research investigating these associations thus far largely relies on total or domain-level scores. This study aimed to employ a higher degree of abstraction to examine associations between psychopathy symptoms and various interpersonal outcomes at different levels of the psychopathy trait hierarchy. The Comprehensive Assessment of Psychopathic Personality (Cooke et al., 2012) was used, allowing for the highest level of nuance, with 33 individual symptom scales. A variety of different interpersonal outcome variables were collected using multiple methods. A university sample ( N = 669) was used and informant reports ( N = 337) were collected. Consistent with our hypotheses, correlation analyses indicated that there were distinct, and at times unique, associations between symptoms and interpersonal outcomes. Furthermore, regression models and dominance analyses showed taking a symptom-level approach can add incremental information over factor scores, particularly for self-reported outcomes. Future research should seek to replicate these findings across populations to elucidate any consistent patterns that could aid in the assessment and treatment of PPD.

We investigated psychopathy from the neurobiological perspective of reinforcement sensitivity theory (RST). In contrast to previous semantically derived self-report scales, we operationalised RST systems neurally with evoked electroencephalography (EEG). Participants were from a community sample weighted towards externalising psychopathology. We compared the Carver & White Behavioural Inhibition System (BIS)/Behavioural Approach System (BAS) scales with EEG responses associated with RST's systems of goal conflict (aka 'behavioural inhibition'), repulsion/outcome conflict (aka 'fight/flight/freeze') and attraction (aka 'approach'). Bivariate correlations and multiple regression analysis yielded results generally consistent with past literature for associations between psychopathy and the self-report BIS/BAS scales. There were some differences from self-report associations with neural measures of RST. With EEG measures, (1) no meaningful associations were observed between any psychopathy scales and the attraction system; (2) affective-interpersonal traits of psychopathy were negatively associated with goal conflict; (3) disinhibition-behavioural traits of psychopathy were negatively associated with goal conflict but, unexpectedly, positively associated with outcome conflict. These results indicate frontal-temporal-limbic circuit dysfunction in psychopathy as specific domains were linked to neural deficits in goal conflict processing, but there was no evidence for deficits in attraction-related processes., (© 2024 The Authors Personality and Mental Health Published by John Wiley & Sons Ltd.)

Background: Many original studies have evaluated the validity and utility of the Alternative Model for Personality Disorders (AMPD) in Iran. However, the present review is a unique attempt to summarize the data in a critical framework to cover gaps in the AMPD research and determine future directions. The review aimed to explore the psychometric evidence for the AMPD, including reliability (alpha coefficient) and validity (construct, convergent, criterion, and incremental types) data in Iran. We also reviewed the overlap between the two AMPD criteria and the associations between the constructs and general psychopathology., Methods: We searched PubMed, PsycNet, Google Scholar, and three national databases for English and Persian records related to the AMPD from January 2013 to 2023. Several keywords and criteria were applied to select studies before summarizing the data., Results: The self-report scales were the first-line measures to assess the AMPD constructs, while interviews were rarely used. The research body provided relative support for both the unidimensional nature of Criterion A measures and the five-factor structure of Criterion B measures. Regarding Criterion B, however, there are still questions about the validity of the disinhibition factor and its clinical utility and generalizability., Conclusion: Although a decade of research on the AMPD in Iran has contributed to improving our knowledge, the current review provided a more comprehensive and clear profile of this model's validity and generalizability to Iranian culture. We discussed the details of validation studies, limitations, and future considerations., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article., (© 2024 The Author(s).)

In this study, we compare the incremental predictive capacities of the Diagnostic and Statistical Manual of Mental Disorders , Fifth Edition, Text Revision (DSM-5-TR) Section II personality disorders (SII-PDs) with Section III trait domains of the Alternative Model of Personality Disorders (AMPD) in a psychiatric outpatient sample ( N = 185). To this end, a series of hierarchical regression analyses was conducted in which the 10 SII-PDs and the five AMPD trait domains served as the predictor variables and five areas of clinical dysfunction as the criterion variables. Two models for each criterion were tested. In Model A, the 10 PDs were entered as a block, followed by the block entry of trait domains; in Model B, the block entry of these predictors was reversed. As the AMPD was designed to address the shortcomings of the SII-PDs, it was hypothesized that the AMPD trait domains would show greater predictive capacity vis-à-vis the latter by (a) explaining more overall variance for each criterion variables when entered first into the model versus when SII-PDs was entered first and (b) explaining more incremental variance than SII-PDs when block was entered second. These hypotheses were partially supported. Overall, the AMPD trait domains predicted more variance than SII-PDs and demonstrated better model fit and more predictive power for three of the criterion variables. Similarly, the AMPD domains predicted a significant but modest incremental increase in variance over that of the SII-PDs for three of the criterion variables. We conclude that more work needs to be done to improve the AMPD, particularly in the assessment of externalizing psychopathology as it relates to clinical dysfunction.

Our study compared the impact of administering Symptom Validity Tests (SVTs) and Performance Validity Tests (PVTs) in in-person versus remote formats and assessed different approaches to combining validity test results. Using the MMPI-2-RF, IOP-29, IOP-M, and FIT, we assessed 164 adults, with half instructed to feign mild traumatic brain injury (mTBI) and half to respond honestly. Within each subgroup, half completed the tests in person, and the other half completed them online via videoconferencing. Results from 2 ×2 analyses of variance showed no significant effects of administration format on SVT and PVT scores. When comparing feigners to controls, the MMPI-2-RF RBS exhibited the largest effect size (d = 3.05) among all examined measures. Accordingly, we conducted a series of two-step hierarchical logistic regression models by entering the MMPI-2-RF RBS first, followed by each other SVT and PVT individually. We found that the IOP-29 and IOP-M were the only measures that yielded incremental validity beyond the effects of the MMPI-2-RF RBS in predicting group membership. Taken together, these findings suggest that administering these SVTs and PVTs in-person or remotely yields similar results, and the combination of MMPI and IOP indexes might be particularly effective in identifying feigned mTBI., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Luciano Giromini is a member of the LLC that owns the rights to the Inventory of Problems-29 (IOP-29).

Objective: Research so far has investigated the bivariate relationships between psychopathic traits, romantic attachment, and emotion dysregulation. However, no research thus far has examined these concepts in their interrelatedness. The aim of the present study was therefore to shed light on the possible linking mechanisms among these concepts, examining the mediating role of emotion dysregulation in the psychopathic traits-romantic attachment link., Method: The present study was based on an undergraduate (N = 238, M age = 20.36 years) and a community sample (N = 521, M age = 35.27 years) from the Dutch population. Participants were administered self-report measures of psychopathic traits (measured with both the Self-Report Psychopathy Short-Form and the Triarchic Psychopathy Measure), emotion dysregulation (Difficulties in Emotion Regulation Scale - Brief Version) and romantic attachment (Experiences in Close Relationships-Revised). Correlation analyses and mediation analyses using a bootstrapping approach were conducted., Results: Results showed that all the dimensions of psychopathic traits were related to both romantic attachment avoidance and anxiety, and that emotion dysregulation mediated all these associations (with only few exceptions). Except for boldness, all other dimensions of psychopathic traits were related to greater emotion dysregulation and, in turn, to insecure romantic attachment., Conclusions: It is argued that the role of emotion regulation processes deserves more attention for the theoretical and clinical understanding of psychopathic traits and their correlates in the interpersonal domain, such as romantic attachment (in)security. When their interrelationships will be better understood, emotion regulation and attachment could represent relevant targets for intervention with individuals presenting psychopathic traits., Competing Interests: Competing interests: None., (© 2024 Giovanni Fioriti Editore s.r.l.)

The Minnesota Multiphasic Personality Inventory-3 (MMPI-3) includes a new Impulsivity (IMP) scale designed to assess for poor impulse-control and non-planful behavior, which was added to broaden the utility of the instrument. The current study aimed to examine the criterion and incremental validity of the IMP scale. A university student sample ( n = 1,440) and a community sample oversampled for externalizing tendencies ( n = 231) were used for this purpose, and IMP scores were compared to scores on various well-validated criterion measures of impulsivity and externalizing psychopathology. To examine the scale's incremental validity, hierarchical multiple regression analyses were conducted to determine whether IMP adds to other MMPI-3 Specific Problem (SP) scales in the prediction of relevant criteria. The IMP scale primarily showed meaningful correlations with the Negative Urgency and Positive Urgency on the UPPS-P. Significant correlations were also observed with the cognitive, behavioral, disinhibition, and lifestyle domains of various psychopathy measures, as well as measures of antisocial personality disorder and substance use. The IMP scale scores accounted for incremental variance in most of the directly relevant criterion measures above and beyond scores of other MMPI-3 SP scales. Several important caveats, limitations, and future directions are discussed., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Martin Sellbom and Yossef S.

Since the research on contemporary personality models-and psychopathology-mainly originate from the Western world, we aimed to test the factorial structure of two trait systems assessed with the Personality Inventory for DSM-5 (PID-5) in a non-Western sample and to compare the extracted models' relative associations with binge eating disorder (BED) and bipolar spectrum disorder (BSD) symptoms. A community sample (N = 516; 72% female) was administered the PID-5, which can operationalize both the DSM-5 and ICD-11 systems. The factor structures of both systems were tested using exploratory structural equation modeling (ESEM). The congruence coefficients of all factor loadings with international studies were calculated. The Binge Eating Scale (BES), Bipolar Spectrum Diagnostic Scale (BSDS), and Hypomania Checklist-32-Revised (HCL-32) were used to measure the criterion variables. Linear regression models were used for comparing the DSM-5 and ICD-11 systems in predicting the BED and BSD. The findings supported five-factor solutions for both trait systems. Both systems significantly predicted dimensional measures of both BED and BSD (all p < 0.001). The present findings support an acceptable five-factor structure for both personality systems in the non-Western sample. Different algorithms of maladaptive domains on both systems are related to binge eating and bipolar spectrum psychopathology., (© 2023 John Wiley & Sons, Ltd.)

The purpose of the present study was to revise and update the MMPI-2-RF personality disorder (PD) syndrome scales for the Minnesota Multiphasic Personality Inventory-3 (MMPI-3). Study 1 describes the development of the MMPI-3 PD syndrome scales in three separate samples of community participants (n = 1,591), university students (n = 1,660), and outpatient mental health patients (n = 1,537). The authors independently evaluated each of the 72 new MMPI-3 items and rated them for appropriateness for scale inclusion and used various statistical procedures for final item selection. Ultimately, all 10 scales were revised, with nine incorporating items that were new to the MMPI-3. In Study 2, we subsequently validated the new MMPI-3 PD Syndrome scales against measures of traditional PD measures, trait measures of the Alternative Diagnostic and Statistical Manual of Mental Disorders, fifth edition-5 model of personality disorders (AMPD) and the five-factor model (FFM) of personality, and specific criterion measures of externalizing, psychopathy, narcissism, emotional dysregulation, and self-harm, in two samples of university students (ns = 489 and 645). With some exceptions, the results were generally supportive of the convergent and discriminant validities of the MMPI-3 PD Syndrome scales. The Histrionic PD scale in particular was associated with questionable results and diverged most strongly from the theoretical construct it was originally meant to reflect. Further continuous validation of the scales is needed, especially in clinical samples, but the findings to date are promising. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The International Classification of Diseases, 11th Edition (ICD-11) includes a new personality disorder (PD) severity diagnosis that may be further characterized using up to five trait domain specifiers. Most of the previous studies have investigated the ICD-11 trait domains using self-report measures. The present study aimed to validate ICD-11 PD trait domains using a multimethod design in a community mental health sample (n = 336). We conducted two confirmatory factor analyses to examine the factor structure of the ICD-11 PD trait model, utilizing clinician-rating, self-report, and informant-report measures. Finally, we examined associations between clinician-rated, self-reported, and informant-reported ICD-11 trait domains with external criteria, specifically traditional PD symptoms and the five-factor model of normal personality. All clinician-rated, self-reported, and informant-reported domain scores loaded meaningfully on their expected factors when controlling for nontrivial method factors. Generally, the trait domains exhibited meaningful associations with conceptually relevant external criteria, although the anankastia domain exhibited more variability in its pattern of correlations across methods. Overall, the ICD-11 trait domain model shows promising reliability and validity, indicating good progress within the field of PD assessment toward a more useful PD operationalization.

Dimensional psychopathology scores measure symptom severity; cutting across disorder categories. Their clinical utility is high given comorbidity, but their neural basis is unclear. We used scalp electroencephalography (EEG) to concurrently assess neural activity across internalizing and externalizing traits. "Theta rhythm" (4-7 Hz) spectral power at the frontal midline site Fz in specific goal conflict and action error phases within a trial of a Stop-Signal Task was extracted using process-specific contrasts. A final sample of 146 community participants (63 males, 83 females; mean age = 36; SD = 9; range = 18 - 56), oversampled for externalizing disorder (49% diagnosed with a DSM-5 externalizing disorder), also supplied psychopathology and personality data. We used the Minnesota Multiphasic Personality Inventory-3 (MMPI-3) to measure symptoms and traits of psychopathology. An MMPI-3 measure of the higher-order internalizing psychopathology spectrum was positively correlated with action error theta. An MMPI-3 measure of the higher-order spectrum of externalizing psychopathology was negatively correlated with goal-conflict theta. We showed that goal-conflict and error theta activity are higher-order processes that index psychopathology severity. The associations extend into the nominally healthy range, and so reflect theta-related factors that apply to the general population as well as patients with sub-threshold diagnoses., Competing Interests: Martin Sellbom is a paid consultant to the University of Minnesota Press, publisher of the MMPI-3, which was included in this research.

Psychiatric illnesses form spectra rather than categories, with symptoms varying continuously across individuals, i.e., there is no clear break between health and disorder. Dimensional measures of behaviour and brain activity are promising targets for studying biological mechanisms that are common across disorders. Here, we assessed the extent to which neural measures of the sensitivity of the three biological systems in the reinforcement sensitivity theory (RST) could account for individual differences in a latent general factor estimated from symptom counts across externalising disorders (EXTs). RST explanatory power was pitted against reduced P300, a reliable indicator of externalising per previous research. We assessed 206 participants for DSM-5 EXTs (antisocial personality disorder, conduct disorder, attention-deficit/hyperactivity disorder, intermittent explosive disorder symptoms, alcohol use disorder, and cannabis use disorder). Of the final sample, 49% met diagnostic criteria for at least one of the EXTs. Electroencephalographic measures of the sensitivities of the behavioural activation system (BAS), the fight/flight/freeze system, and the behavioural inhibition system (BIS), as well as P300 were extracted from the gold bar-lemon and stop-signal tasks. As predicted, we found that low neural BIS sensitivity and low P300 were uniquely and negatively associated with our latent factor of externalising. Contrary to prediction, neural BAS/"dopamine" sensitivity was not associated with externalising. Our results provide empirical support for low BIS sensitivity and P300 as neural mechanisms common to disorders within the externalising spectrum; but, given the low N involved, future studies should seek to assess the replicability of our findings and, in particular, the differential involvement of the three RST systems., Competing Interests: Martin Sellbom is a paid consultant to the University of Minnesota Press, publisher of the MMPI-3, which was included in this research.

Objective: Despite accumulating evidence of significant albeit moderate associations between childhood trauma and psychopathy, little is known about the potential moderators of these associations. To advance knowledge in this area, the present study investigated the moderating role of resilience in the childhood trauma-psychopathy link., Method: A community sample of 521 adult participants from the Netherlands (40.1% men; M age = 35.27 years, SD = 15.99) completed two self-report questionnaires measuring psychopathic personality traits: a self-report measure of resilience and a retrospective measure of childhood traumatic experiences. Correlation analyses were employed to investigate bivariate associations among study variables. Moderated multiple regression analyses with bootstrapping followed by simple slope analyses were employed to examine Childhood Trauma × Resilience interactions in predicting scores of psychopathy subscales., Results: Childhood trauma had small positive associations with psychopathic traits across the board, with the exception of a small negative association with boldness traits, as well as a small negative association with resilience. Resilience was strongly and positively related to boldness, and negatively related to affective (callousness, meanness) and behavioral (antisocial, disinhibition) traits of psychopathy. Resilience moderated six out of seven associations between childhood trauma and psychopathic traits., Conclusions: Resilience appeared to represent a significant buffer in the associations between childhood traumatic experiences and psychopathic traits, such that these associations became weaker and nonsignificant (and even negative for boldness) at higher levels compared to lower levels of resilience.

Objective: The Minnesota Multiphasic Personality Inventory (MMPI) instruments have a long history with respect to the assessment of psychopathic personality traits. The most recent version, the MMPI-3, should be in a good position to continue this tradition, and the aim of the current research was to evaluate its scales for this purpose. We examined, on the basis of previous research, how well conceptually relevant MMPI-3 scales mapped onto dominant contemporary psychopathy models: the traditional three-factor model and triarchic psychopathy model., Hypotheses: We hypothesized that MMPI-3 markers of internalizing would be negatively correlated with boldness, whereas broad and specific markers of externalizing proclivities would be associated with disinhibition and antisociality. We also hypothesized that egocentricity and callousness would be associated with MMPI-3 scales measuring various features of externalizing, interpersonal aggression/antagonism, and grandiosity., Method: We used archival samples of male prison inmates (n = 452), community members with externalizing proclivities (n = 205), and university students (n = 645). These participants completed the Expanded Levenson Self-Report Psychopathy Scale and the Triarchic Psychopathy Measure., Results: Zero-order correlation analyses indicated support for many of our hypotheses across samples, with notable exceptions. Regression and dominance analyses yielded information about the most potent MMPI-3 predictors of each psychopathy domain, with consistency across the three samples. Boldness was associated with low scores on Emotional/Internalizing Dysfunction, Low Positive Emotions, Shyness, and Negative Emotionality/Neuroticism and high scores on Self-Importance and Dominance. For meanness and disinhibition, we found substantial overlap with MMPI-3 scales (e.g., Behavioral/Externalizing Dysfunction, Antisocial Behavior). Meanness was indicated by high Aggression, Cynicism, Aggressiveness, and Disaffiliativeness; disinhibition/antisociality was primarily marked by high Antisocial Behavior, Hypomanic Activation, Impulsivity, and Disconstraint; and Anger Proneness, Aggression, and Cynicism were secondary indicators., Conclusions: These findings provide support for using the MMPI-3 in clinical assessments to corroborate other sources of information regarding psychopathy as well as generate hypotheses for further consideration.

The Personality Inventory for DSM-5 (PID-5) was designed to measure the personality traits of the alternative model of personality disorders (AMPD). It is comprised of 25 lower order facet scales. Factor analytic investigation of these scales has consistently recovered five factors corresponding to the trait domains of the AMPD. Most of these factor analytic studies, however, have been conducted in the United States and Western European countries and languages. Fewer studies have examined the factor structure of the PID-5 in East Asian countries; and no studies have examined whether the five-factor structure found in Western countries/cultures/languages is congruent with those from East Asia. In this study, we examine the PID-5 factor structure in adult community samples from the People's Republic of China (PRC; N = 233 [116 females], M age = 35.88, range = 22-60) and the United States ( N = 237 [118 females], M age = 35.44, range = 22-60) using exploratory structural equation modelling and assess whether the factor structures across these samples are congruent using Tucker's congruence coefficient. A five-factor solution was an adequate-to-good fit in both samples. The factor structure obtained from the U.S. sample was congruent with the PID-5 normative sample factor structure. The compositional configuration of the factors in the five-factor structure in the PRC sample, however, showed poor congruence with the U.S. sample. A six-factor model proved to be a better fitting model in the PRC sample. We conclude that the PID-5 does not have factor structure equivalence across U.S. and Chinese cultures/languages.

No clinician-rating tool has formally been developed to assess the ICD-11 model of personality disorder (PD) severity. We therefore developed and evaluated the 14-item personality disorder Severity ICD-11 (PDS-ICD-11) Clinician-Rating Form. A combined sample of 195 patients was rated by mental health professionals or clinical research assistants in New Zealand using the PDS-ICD-11 Clinician-Rating Form. Responses were subjected to item-response theory analysis and confirmatory factor analysis. In a subsample, we examined interrater reliability and convergence with self- and informant-reported measures of personality impairment, dysfunction in various psychopathology domains, and traditional PD symptoms. Item-response theory and confirmatory factor analyses supported the item functioning and unidimensionality, respectively, of the PDS-ICD-11 Clinician-Rating Form. The interrater reliability was very promising (intraclass correlation coefficient = 0.94, p < 0.001). PDS-ICD-11 Clinician-Rating Form scores were associated with established measures of personality dysfunction at large effect sizes. This initial development study suggests that the PDS-ICD-11 Clinician-Rating Form constitutes a psychometrically sound instrument that provides a clinically based impression of the severity of personality dysfunction according to the official ICD-11 description. More research is needed to corroborate its validity and utility, and a structured interview is warranted for diagnostic purposes. The final PDS-ICD-11 Clinician-Rating Form is included as online supporting information., (© 2023 The Authors Personality and Mental Health Published by John Wiley & Sons Ltd.)

Objective: Previous evidence indicates that scales from the Minnesota Multiphasic Personality Inventory (MMPI) family of instruments can measure self-reported posttraumatic stress disorder (PTSD) symptomology and differentiate symptom clusters, including in forensic disability assessments. However, limited research has examined assessment of PTSD symptoms with the MMPI-3, the most recent MMPI instrument. The goal of the current study was to identify the strongest MMPI-3 scale predictors of individual PTSD symptom clusters, measured via self-report., Methods: Using a sample of 716 disability claimants (54.2% men; M age  = 42.98, SD = 10.87; 81.8% White), correlation, regression, and dominance analyses were performed to examine associations between scores on MMPI-3 scales and latent PTSD symptom cluster factors derived using confirmatory factor analyses from items of the Detailed Assessment of Posttraumatic Stress (DAPS), and to identify the strongest predictor of each symptom cluster when MMPI-3 scales were concurrently considered., Results: Results indicate that conceptually expected MMPI-3 scale scores were meaningfully associated with PTSD symptom cluster factors, with the MMPI-3 Anxiety-Related Experiences (ARX) scale demonstrating the strongest and most consistent associations across symptom clusters., Conclusions: Results of the current study largely converge with previous empirical studies of self-reported PTSD symptoms in disability claimant settings with the MMPI instruments. Interpretive implications for the MMPI-3, limitations, and future research directions are discussed., (© 2023 The Authors. Journal of Clinical Psychology published by Wiley Periodicals LLC.)

Background: The Minnesota Multiphasic Personality Inventory-3 (MMPI-3) is a commonly used psychological test that includes several scales relevant to measuring manic and depressive symptoms of bipolar spectrum disorders., Aims: The goal of the present study was to evaluate the construct validity of MMPI-3 scale scores with respect to self-report measures of bipolar psychopathology., Materials & Methods: Using a sample of 644 university students in New Zealand, we calculated correlations between scores on the MMPI-3 and the Hypomanic Personality Scale-Short Form (HPS-SF) total and factor scores and the Altman Self-Report Mania Scale (ASRM) total and item scores., Results: For associations against the HPS-SF, almost all of the hypotheses were supported, whereas for the ASRM scale, several were not. We also estimated a series of regression models predicting HPS-SF and ASRM scores from meaningfully associated MMPI-3 scores. Hypomanic Activation (RC9), Activation (ACT), and Self-Importance (SFI) scores emerged as the most consistent and substantial predictors of criteria, with SFI scores being more specifically associated with total scores and criteria related to Social Vitality. Several internalizing and thought dysfunction MMPI-3 scales were also meaningfully associated with scores on the HPS-SF and ASRM., Discussion & Conclusion: Implications and limitations, such as the use of a university student convenience sample, are discussed., (© 2023 The Authors.

Current guidelines for conducting symptom validity assessments require that professionals administer multiple symptom validity tests (SVTs) and that the SVTs selected for their evaluations provide nonredundant information. However, not many SVTs are currently available, and most of them rely on the same, (in)frequency-based, feigning detection strategy. In this context, the Inventory of Problems (IOP-29) could be a valuable addition to the assessor's toolbox because of its brevity (29 items) and its different approach to assessing the credibility of presented symptoms. As its ecological validity has been poorly investigated, the present study used a criterion groups design to examine the classification accuracy of the IOP-29 in a data set of 174 court-ordered psychological evaluations focused on psychological injury. The validity scales of the Minnesota Multiphasic Personality Inventory-2 Restructured Form and the total score of the Structured Inventory of Malingered Symptoms were used as criterion variables. Overall, the results of this study confirm that the IOP-29 is an effective measure (1.70 ≤ d ≤ 2.67) that provides valuable information when added to the multimethod assessment of symptom validity in civil forensic contexts.

Introduction: Prevalence rates and correlates of personality disorders (PD) are relevant to health care policy and planning., Objectives: To present normative data for self-reported ICD-11 personality disorder (PD) features including tentative cut-off scores and prevalence rates for severity levels along with psychosocial correlates., Methods: The Personality Disorder Severity ICD-11 (PDS-ICD-11) scale and criterion measures of impairment were administered to a social-demographically stratified sample of Danish citizens (N = 8,941) of which 3,044 delivered complete data. Item-Response Theory (IRT) was employed to indicate cut-offs based on standard deviations from the latent mean., Results: The unidimensionality of the PDS-ICD-11 score was supported and IRT analysis suggested norm-based thresholds at latent severity levels. Expected associations with criterion measures were found., Conclusion: The normative data portray ICD-11 PD features in the general population and allow for interpretation of PDS-ICD-11 scores (e.g., scores of 12, 16, and 19 may indicate mild, moderate, and severe dysfunction), which may inform health care policy and planning. A total weighted prevalence of 6.9 % of the Danish general population is estimated to have clinically significant personality dysfunction, proportionally composed of Mild (4.8 %), Moderate (1.2 %), and Severe (0.9 %) levels.

In a previous study, it was reported that the typically replicable factor structure of the Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders, fifth edition (PID-5) was noninvariant across samples of Black American and White American university students. The investigators of that study attributed this noninvariance across these two racial groups to Black American racialization, defined as Black individuals living in a predominantly non-Black society. In the current investigation, we examined further the effects of Black racialization by examining PID-5 factor structure invariance using a sample of nonracialized Black (Nigerian) university students (i.e., Black people living in a primarily Black society) and a sample of White American students. The factor structure of the PID-5 across the samples indicated overall configural invariance, suggesting that the same PID-5 facet traits, for the most part, load on the same factors for the nonracialized Black people and White Americans. This result is consistent with the view that Black racialization likely contributes to PID-5 factor structure noninvariance across White and Black Americans. There were some differences, however, between the Nigerian and White American students with respect to metric invariance and scalar invariance, suggesting the facet-to-factor loadings have different magnitudes of association across groups and that domain scale score elevations in Nigerian and White American students are not comparable; this was particularly prominent for the disinhibition domain.

The ICD-11 has a new diagnostic system for personality disorder, which includes five optional trait specifiers to characterize the diagnosed pathology. The current study evaluated the internal structure and construct validity of the Personality Assessment Questionnaire for ICD-11 (PAQ-11) personality trait domains in a US population-representative community sample. An exploratory factor analysis revealed the support for a four-factor model underlying the 17 PAQ-11 items, reflecting four of the five ICD-11 trait domains (Negative Affectivity, Detachment, Disinhibition and Anankastia). Moreover, correlation analyses revealed that the PAQ-11 domain scale scores were associated, as expected, with their counterparts from two other ICD-11 trait domain measures, as well as with traditional personality disorder scores. More broadly, the results raised questions about the structural integrity of the Dissociality domain scale, and the discriminant validity of the Disinhibition and Anankastia scales. The overall conclusion was nevertheless promising with respect to the PAQ-11 serving as a brief screening measure for the ICD-11 trait domains., (© 2022 The Authors Personality and Mental Health Published by John Wiley & Sons Ltd.)

The ICD-11 has now taken effect and includes a new dimensional personality disorder (PD) diagnosis. The current study aimed to examine Aotearoa/New Zealand practitioners' perceptions of the clinical utility of the new PD system. A sample of 124 psychologists and psychiatrists completed a survey, applying the DSM-5 and ICD-11 PD diagnostic systems to a current patient, and completed clinical utility metrics on the DSM-5 and ICD-11 models. Additional open-ended questions further elicited clinicians' perceptions of the strengths, weaknesses and potential application issues of the ICD-11 PD diagnosis, and these responses were analysed through thematic analysis. Overall, the ICD-11 system was rated higher than the DSM-5 on all six clinical metrics, with no significant difference between psychologists' and psychiatrists' ratings. Five themes emerged: appreciation for an alternative to DSM-5, structural barriers preventing ICD-11 PD implementation, personal barriers to ICD-11 implementation, diagnoses viewed as low utility, clinician preference for formulation and cultural safety considerations for implementation of ICD-11 PD in Aotearoa/NZ. Overall, clinicians had positive opinions of the clinical utility of the ICD-11 PD diagnosis, although expressed some concerns about its implementation. The study expands upon initial evidence that mental health practitioners have generally positive perceptions of the ICD-11 PDs' clinical utility., (© 2023 The Authors Personality and Mental Health Published by John Wiley & Sons Ltd.)

The International Classification of Diseases, 11th Edition (ICD-11) has reconceptualized personality disorders (PD), and measures are therefore being developed to aid the assessment of ICD-11 PD. The present study examined the validity of the recently developed self-report inventory the Personality Disorder Severity for ICD-11 (PDS -ICD-11 ), and its utility in differentiating across ICD-11 PD severity levels in a community mental health sample ( n = 232). We examined the associations between the PDS- ICD-11 with various clinician ratings, self-report questionnaires, and informant-report measures of dimensional personality impairment and traditional Diagnostic and Statistical Manual of Mental Disorders, fifth edition PDs. Further, we examined mean group differences in PDS- ICD-11 scores between levels of ICD-11 PD clinician diagnosis. The PDS- ICD-11 exhibited moderate-to-large associations with all clinician ratings, and more variable associations with self-report and informant-report measures. PDS- ICD-11 mean scores were significantly different across all levels of ICD-11 PD clinician-rated diagnostic levels. These findings provide additional promising evidence for the validity and utility of the PDS- ICD-11 for the assessment of ICD-11 PD in community mental health patients.

The aim of the current study was to further examine the psychometric properties of the Expanded Levenson Self-Report Psychopathy Scale (E-LSRP; Christian & Sellbom, 2016). Specifically, its reliability, internal structure, and convergent and discriminant validity were evaluated using university ( N = 367) and community samples ( N = 205) from Aotearoa New Zealand. The results provided support for the reliability and validity of the E-LSRP in both samples. More specifically, the internal consistency estimates of the E-LSRP were above the meaningful threshold, indicating good reliability. Furthermore, using confirmatory factor analysis, the hypothesized three-factor structure was supported and conceptually consistent with Cooke and Michie's (2001) Psychopathy Checklist-Revised (PCL-R) three-factor model. Lastly, the results generally provided support for the convergent and discriminant validity of the E-LSRP subscales; the E-LSRP Egocentricity was associated with criteria relevant to interpersonal impairment, the Callous scale with criteria relevant to the affective psychopathy domain, and the Antisocial scale with criteria representing behavioral dysfunction. Overall, the E-LSRP is a promising tool for assessing psychopathy in nonincarcerated populations.

The Hierarchical Taxonomy of Psychopathology (HiTOP; Kotov et al., 2017, 2021) is offered as a dimensional alternative to traditional categorical diagnostic nosologies such as the Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD ). HiTOP researchers have recently published an open-source assessment system for clinical implementation, the HiTOP Digital Assessment and Tracker (Jonas et al., 2021). Here, we argue that the Minnesota Multiphasic Personality Inventory-3 (MMPI-3; Ben-Porath & Tellegen 2020a), given its structural similarities to HiTOP, can augment these efforts to shift the diagnostic paradigm, with the additional strength of being comprehensively validated, standardized, and normed. Sellbom et al. (2021) examined the factor structure of the MMPI-3 Specific Problems Scales (plus RC6 and RC8), finding a pattern of latent factors much like those proposed by HiTOP in both a general mental health sample and a prisoner sample. The present study is a partial replication of Sellbom et al. (2021) with a primary medical care outpatient sample ( n = 164) and a college student sample ( n = 529). A sequential factoring approach yielded emergent structures that are comparable to the HiTOP model. These findings with different and important samples support the generalizability of the MMPI-3 in assessing HiTOP constructs. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Objectives: The International Classification of Diseases , 11th edition includes a new personality disorder diagnosis, in light of growing concerns of the categorical personality disorder diagnoses. The purpose of the current study was to examine the reliability and validity of the severity dimension of the new International Classification of Diseases , 11th edition diagnosis, through multi-method assessment., Method: In a community mental health sample ( n = 311), we examined the interrater reliability of the severity diagnosis and evaluated the diagnosis against self-report measures of dimensional personality pathology and psychopathology constructs and traditional categorical and informant-report measures., Results: Intraclass correlations indicated 'excellent' reliability of the diagnostic ratings. Large associations were observed between the International Classification of Diseases , 11th edition clinician diagnosis and overall impairment measures. Generally, the International Classification of Diseases , 11th edition clinician diagnosis exhibited largest associations with measures of internalising dysfunction, and more variable associations with interpersonal and externalising impairment. The International Classification of Diseases , 11th edition clinician diagnosis showed a large association with borderline personality disorder symptom scores and moderate associations with Paranoid, Schizoid and Avoidant personality disorder scores. Similar patterns emerged of the associations between the International Classification of Diseases , 11th edition personality disorder diagnosis with self-report and informant-report measures, although the associations were larger with self-report measures., Conclusion: These findings provide promising initial evidence for the reliability and validity of the new International Classification of Diseases , 11th edition personality disorder diagnosis, indicating that the new conceptualisation of personality disorders may address issues within the categorical model.

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 Level of Personality Functioning Scale-Brief Form 2.0 is a frequently used self-report inventory that may be used to screen for self- and interpersonal dysfunction according to the DSM-5 Alternative Model for Personality Disorders (AMPD) and the ICD-11 Classification of Personality Disorders. Nevertheless, reliable norms and cut-off scores to aid interpretation and clinical decision making are still lacking. The LPFS-BF and relevant impairment measures were administered to a sociodemographically stratisfied sample of 2,002 adults from the general Danish population of whom 713 individuals eventually delivered data for inclusion in the present study. The unidimensionality of the LPFS-BF scores was established using Confirmatory Factor Analysis (CFA). Item-Response Theory (IRT) analysis indicated satisfactory item functioning for all 12 items and suggested normative observed score thresholds at different latent severity levels. Meaningful associations were found between the LPFS-BF norm-based cut-off scores, quality of life, and social and occupational functioning. This study presented the first normative data for LPFS-BF, which specifically applies to Denmark but likely also other socioeconomically comparable Nordic and Western societies. These results allow for interpretation of LPFS-BF scores and clinical decision-making. Future research should corroborate these findings and compare them to scores obtained in other general population samples., (© 2022 The Authors Personality and Mental Health Published by John Wiley & Sons Ltd.)

The International Classification of Diseases (ICD-11) features a new classification of personality disorders (PD), focusing on the severity of PD. Although there are numerous self-report measures that assess PD severity, to date only the Personality Disorder Severity- ICD-11 ( PDS -ICD-11 ) is based on ICD-11 's operationalization of PD. Initial results indicated that the PDS- ICD-11 measures a unidimensional construct, but the assumptions made for scoring its bipolar items had not been fully examined. The aim of this study is to fill this gap and investigate the latent structure of the German version of the PDS- ICD-11 using nominal response models (NRM), which allow for testing these assumptions. We applied the PDS- ICD-11 together with other self-report measures in a sample of 1,228 individuals from the general population. NRM indicated an acceptable fit of a unidimensional model, with only few deviations from the theoretically imposed scoring scheme. The total score was sufficiently reliable and correlated meaningfully with other self-report measures of PD severity. Regarding Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and ICD-11 maladaptive trait domains, the total score was found to be most strongly associated with negative affectivity, whereas associations with antagonism and anankastia were small or nonsignificant. We conclude that the proposed scoring scheme of the PDS- ICD-11 items is acceptable, and the examined psychometric properties of the German version largely correspond to the results from the English-language development study. The total score, however, depicts more internalizing than externalizing personality pathology. Future studies should investigate the diagnostic efficiency of the PDS -ICD-11 scale using multiple methods and time points as well as clinical and forensic samples.

The triarchic model of psychopathy emphasizes the role of three phenotypic personality domains (boldness, meanness, and disinhibition) that have been operationalized using the well-established Multidimensional Personality Questionnaire. The present study sought to further validate the MPQ-Tri scales and examine their temporal stability and predictive validity across two time points (ages 18 and 26) from the Dunedin Multidisciplinary Health and Development Study, a population-representative and longitudinal sample ( N = 1,037). This investigation necessitated modification of the MPQ-Tri scales to enable their use in a broader range of samples, including the Dunedin Study. The revised MPQ-Tri scales demonstrated good temporal stability, and correlation and multiple linear regression analyses predominantly revealed associations consistent with theoretical expectations. Overall, the findings provide support for the MPQ-Tri scales as reliable, stable, and valid measures of the triarchic constructs, which provide a unique opportunity to examine highly novel research questions concerning psychopathy in a wide variety of samples.

Most research on personality disorders (PDs) relies upon self-reported information, commonly collected via standardized self-report inventories or structured interviews. Such data might, for instance, be culled from archival records from applied evaluative contexts or collected as part of dedicated anonymized research studies. Many factors-such as disengagement, distractibility, or motivation to appear in a certain manner-may influence whether self-reported information accurately reflects an examinee's genuine personality characteristics. Despite resultant risks to the validity of collected data, very few measures used in PD research include embedded indicators of response validity. In this article, we review the need for validity measures and strategies that exist to identify invalid self-report data, and we offer several suggestions for PD researchers to consider in order to detect invalid self-reported information and improve the quality of their data.

The Expanded-Levenson Self-Report Psychopathy Scale (E-LSRP) was developed by Christian and Sellbom to improve on the psychometric properties of scores on the Levenson Self-Report Psychopathy Scale. The current study investigated the construct validity of scores on the E-LSRP in 393 male inmates. Results provided support for the reliability and construct validity of E-LSRP scores. Specifically, confirmatory factor analysis results demonstrated support for a three-factor model. Additionally, correlation and multiple regression results provided evidence supporting the convergent and discriminant validity of E-LSRP scores against scores on measures assessing psychopathy-related personality traits (e.g., antagonism, disinhibition) and symptoms of internalizing disorders, respectively. Overall, these findings extend those of previous research by establishing that E-LSRP scores demonstrate validity in assessing psychopathy in correctional settings and thus, may be a useful tool for the assessment of psychopathy in these settings.

A prevailing view among researchers and mental health clinicians is that symptoms of antisocial personality disorder (ASPD)/psychopathy decrease as affected individuals reach middle age. In the current investigation, informants were surveyed about the behavior of individuals who they believed showed traits of ASPD/psychopathy and were over the age of 50. A final sample of 1,215 respondents rated the index individuals according to the ASPD/psychopathy traits derived from the pre-publication first draft of the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition , revealing high endorsement of traits associated with ASPD. Survey respondents reported their observations that individuals who met a threshold for putative ASPD/psychopathy continued to engage in antisocial behavior after age 50, and as a result the respondents endured significant harm, including material losses, financial losses, and various self-reported mental health problems. Those who knew the index individuals both before and after the age of 50 were specifically asked whether there was a change in the individual's engagement in manipulation, deceit, and antisocial behavior; 93% of respondents reported that the behavior was just as bad or worse after age 50. Other researchers have suggested that the DSM diagnostic criteria do not accurately describe ASPD/psychopathy symptoms and behavior in older adults, and that the disorder remains stable, but its manifestation changes with age. This study supports those conclusions.

Objective: The general understanding of disorders related to chronic somatic symptoms (e.g., somatic symptom disorder, functional somatic syndromes) is limited because of current categorical conceptualizations in traditional taxonomies. To improve clinical utility and validity, the Hierarchical Taxonomy of Psychopathology offers an empirically grounded dimensional approach. Therefore, the distribution of persistent somatic symptom distress observed in nature is highly relevant for informing decisions related to classification and treatment. This study analyzes the underlying structure of symptoms associated with the somatoform spectrum., Method: Taxometric analyses were used to examine the latent status of the somatoform spectrum, which was measured via a dimensional questionnaire devised as part of the Hierarchical Taxonomy of Psychopathology scale development effort. We generated Comparison Curve Fit Index (CCFI) profile analyses across a clinical sample of psychotherapy outpatients ( n = 487), a community sample of German adults ( n = 451), and a student sample from New Zealand ( n = 549)., Results: In the clinical sample (CCFI mean = 0.38) and in the student sample (CCFI mean = 0.36), a dimensional solution was clearly favored. Results in the community sample (CCFI mean = 0.51) were ambiguous., Conclusions: Across the three independent samples, qualitatively distinct subgroups within the distribution of chronic somatic symptoms could not be identified. Therefore, continuous representations seemed to best represent the structure of somatic symptoms. Implications of these findings for etiology and treatment are discussed., (Copyright © 2022 by the American Psychosomatic Society.)

The concept of "successful" psychopathy has intrigued the field, yet relatively little actual science exists to understand what makes those high in psychopathic traits more or less successful, or even what constitutes "success." In the current study, we examined the validity of the moderated expression hypothesis, including an elaborated version that considers differential configuration of psychopathy traits, as accounting for differences in criminal and noncriminal (the most common operationalization of "success") expressions of psychopathy. The latter was conceptualized from the perspective of the triarchic psychopathy model. We recruited a community sample (n = 212) that had been overweighted toward psychopathic personality traits. The triarchic psychopathy domains of boldness, meanness, and disinhibition were modeled as latent constructs based on scores from multiple psychopathy measures. We examined affective processing dysfunction, various executive cognitive deficits, substance misuse, and socioeconomic indicators (income, education) as potential moderators of associations between psychopathy and criminality. We estimated a series of latent regression models in which we tested interaction effects between hypothesized moderators and a latent criminality variable. We found that affective processing dysfunction, substance misuse, and the triarchic psychopathy domain of disinhibition all moderated the association between meanness and criminality, in that the latter association was stronger as these moderators increased in severity. Disinhibition was also moderated by substance misuse and boldness by both personal income and commission errors from a go/no-go task, though in the case of the latter domain, these moderators served as protective factors against criminality.

The recently released Minnesota Multiphasic Personality Inventory-3 (MMPI-3) includes a revised set of Validity Scales on which there is currently limited validity and clinical utility evidence for the detection of overreporting. The present study evaluated the MMPI-3 Validity Scales in the identification of such response bias. An analogue simulation design was used in which participants in an overreporting condition (163 undergraduate students) were instructed to feign mental health symptoms when responding to the MMPI-3 in the context of a compensation-seeking claim. Two comparison groups (657 undergraduate students and 223 community mental health patients) were instructed to respond to the MMPI-3 under standard instructions. The results indicated that those in the overreporting group generally had higher scores on MMPI-3 substantive scales than did genuine responding patients and students. In addition, results indicated that the criterion validity of the substantive scale scores was compromised in the context of overreporting. All MMPI-3 Validity Scales, particularly Fp ( g = 1.29), F ( g = 1.05), and RBS ( g = 1.11), differentiated the overreporting group from patients with genuine psychopathology. Classification accuracies associated with the overreporting Validity Scale scores were evaluated and generally supported their utility in correctly classifying overreporters and patients. Overall, the findings generally support the validity and clinical utility of the MMPI-3 Validity Scales in the detection of overreporting.

Psychopathic personality disorder (PPD) is a widely researched construct characterized by severe dysfunction in affective, interpersonal and behavioral domains. Inconsistencies across different theoretical formulations and operationalizations have major implications for research and practice. Two separate personality-based perspectives of psychopathy have been proposed, one anchored within the influential five factor model (FFM) of personality and the comprehensive assessment of psychopathic personality (CAPP) model, which was specifically designed as an inclusive concept map of PPD. The current study evaluated the empirical overlap between the CAPP and the FFM-based models of psychopathy to determine the convergences and divergences in providing a personality-based perspective on psychopathy. Participants were undergraduate students ( n = 924) who completed the CAPP-Self-Report (CAPP-SR) and the Elemental Psychopathy Assessment-Short Form (EPA-SF). Results indicated significant convergent validity associations between CAPP-SR scales and conceptually relevant EPA-SF scales (range = .30-.74; median discriminant associations range = .10-.36). Furthermore, an exploratory factor analysis supported the conceptual overlap between the CAPP-SR and EPA-SF scales as representing personality-based models of psychopathy, yielding a 4-factor structure that reflected antagonism, disinhibition, emotional stability, and narcissism. Overall, the findings support the convergence of the CAPP and FFM-based PPD models, at both a basic trait and higher order level. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

The Levenson Self-Report Psychopathy (LSRP) scale is a self-report measure that can be used to assess psychopathic traits in community samples, and recent research suggested that its three-factor model (Egocentricity, Callousness, and Antisocial) has promising psychometric properties. However, no study to date has validated the LSRP in a longitudinal framework. The present study sought to validate the LSRP scale in a longitudinal design using a sample of Dutch emerging adults ( n s = 970 and 693 at time points 1 and 2, respectively). We assessed longitudinal measurement invariance and the stability of psychopathic traits over an 18-month time period, from age 20 to age 21.6. Furthermore, we replicated and extended findings on the factor structure, reliability, and construct validity of the Dutch LSRP scale. Confirmatory factor analysis revealed that the three-factor model fit the data well. Evidence of partial longitudinal measurement invariance was observed, which means that the Dutch translation of the LSRP scale is measuring an equivalent construct (and overall latent factor structure) over time. Psychopathic traits were relatively stable over time. The three LSRP subscales showed largely acceptable levels of internal consistency at both time points and showed conceptually expected patterns of construct validity and predictive validity, with a few notable exceptions.

The purpose of the current study was to evaluate the validity of scores on the Eating Concerns (EAT) scale on the recently released Minnesota Multiphasic Personality Inventory-3 (MMPI-3), which aims to assess for problematic eating behaviours. It was hypothesised that the EAT scale scores would be correlated with binge eating, purging, restrictive eating, weight and body shape concerns. Participants were 396 university students, who completed a series of well-validated eating disorder measures. The EAT scale scores evidenced moderate to large correlations with many symptom dimensions of EDs, including binge eating, purging, restrictive eating and weight and shape concern, thus, supporting the hypotheses and showing evidence for criterion validity. Hierarchical regression analyses also revealed incremental validity for the EAT scale above and beyond other MMPI-3 Specific Problems scale scores. Overall, scores on the new MMPI-3 EAT scale were associated with positive support for validity in a university population and seem promising as a good screening measure for eating pathology., (© 2021.

The MCMI-IV and MACI-II are the most recent iterations of the primary Millon clinical inventories and have become well-established instruments over the course of multiple editions. The MCMI, in particular in its prior editions, and to a lesser extent, the original MACI, have joined the canon of commonly-used psychological instruments in several forensic settings, though they have been met with significant controversy. This controversy is due in large part to complicated and sometimes questionable psychometric and normative referencing qualities that evaluators may find difficult to defend in a court setting. On balance, the instruments, unlike many others, are also supported by a rich though often less-than-understood theoretical backbone which lends depth and explanatory power, but which also can further complicate addressing psycho-legal questions. The authors, representing a mixed perspective on the inventories, generally conclude that while the MCMI-IV and MACI-II rely on a rich theoretical framework, the peer-reviewed literature is virtually non-existent, the need to rely on their predecessor instruments' research literatures are limiting, and the modifying indices have questionable utility in the detecting of response bias. In addition, the normative data and underreporting response styles in family court evaluations cause problems for the MCMI-IV's use in such contexts.

This special issue addresses a major gap in the literature by providing comprehensive, credible reviews of the psychometric evidence for and legal status of some of the most commonly-used psychological and personality assessment measures used in forensic evaluations. It responds to Neal and colleagues' (2019) call for research to improve the state of and access to knowledge about psychological assessments in legal contexts, and encourages critical thinking about forensic assessment in the spirit of improvement. These articles offer clarity about the strengths and weaknesses of a number of assessment instruments to inform psychologists' preparation for expert testimony, lawyers' preparation for direct and cross-examination, judges' evidence admissibility determinations, and scholars' future research. We assembled teams of authors with different perspectives and areas of expertise to review each tool fairly, including several adversarial collaborations. Articles on the Rorschach and R-PAS, MMPI-3, PCL-R, MCMI-IV and MACI-II, PAI and PAI-A, SIRS-2, HCR-20 V3 , TSI and TSI-2, and the MacCAT-CA, ECST-R, and CAST*MR are included. To increase visibility, accessibility, and impact, this issue is published as free access, meaning the articles are available to download without charge. We anticipate these articles will be widely read and useful to scholars and practitioners in both psychology and law.
