The replicability of the personality inventory for DSM-5 domain scale factor structure in U.S. and non-U.S. samples: A quantitative review of the published literature

The sensitivity of the ICD-11 trait model to the symptoms of clinical disorders in young adults

Hierarchical psychopathology contributes to providing a broader picture of the links between emerging personality structures such as the DSM-5/ICD-11 trait models and clinical disorders. The present study aimed to predict the specific and general clinical symptoms by the less studied constructs of the ICD-11 model (negative affectivity, detachment, dissociality, disinhibition, and anankastia). Data from 642 young adults from Iran (63% female, 18-34 years) were collected by three mental symptom scales and the Personality Inventory for DSM-5 (PID-5), which was recently used to harmonize the constructs of the DSM-5 and ICD-11 trait models. Multiple linear regressions showed that the ICD-11 model significantly predicted both the specific clinical symptoms (ranging from R2 = 0.15 to 0.40) and the general factor of clinical symptoms extracted by exploratory factor analysis (R2 = 0.40, all p < 0.001). Negative affectivity was the strongest construct correlated with both the specific symptoms (ranging from β = 0.36 to 0.69) and the general symptom factor (β = 0.59, all p < 0.001). Because the ICD-11 trait model is a practical structure related to the clinical psychopathology in young adults, screening for maladaptive traits can help clinicians in case formulation for diagnosis and treatment.

Replicability of the five-factor structure of DSM-5 and ICD-11 trait systems and their associations with binge eating and bipolar spectrum psychopathology

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.

Differentiation of Self and Interpersonal Functioning with the Level of Personality Functioning Scale - Brief Form 2.0

Research on Criterion A of the alternative model for personality disorders is recently expanding and provides mixed results concerning the unidimensional operational definition of severity by the model, characterized by impaired self (identity and self-direction) and interpersonal (empathy and intimacy) functioning. Studies resulted in one, as well as two or more factor structures. The present study demonstrated the importance of the structural and relational differentiation of self and interpersonal dimensions of personality functioning. One thousand seventy-four participants (community and clinical mixed sample) completed the Level of Personality Functioning Scale - Brief Form 2.0 (LPFS-BF 2.0), the Personality Inventory for DSM-5 Short Form and the Questionnaire for the World Health Organization Disability Assessment. An LPFS-BF 2.0 two-factor structure with self and interpersonal functioning factors was corroborated by confirmatory factor analyses and bifactor modeling. Joint Exploratory Factor Analysis of the LPFS-BF 2.0 domains with maladaptive personality domains clearly differentiated the personality functioning factors. While the self-functioning factor was more closely linked to negative affect (and to disinhibition and psychoticism), the interpersonal functioning factor connected to detachment. Self-functioning predicted functional impairment along and beyond personality domains. The LPFS-BF 2.0 appears a useful tool for clinical routine monitoring of both self and interpersonal functioning.

Understanding the association between normal and maladaptive personality traits: Replication and extension of Morey et al. (2020)

BACKGROUND/OBJECTIVE

The Alternative Model for Personality Disorders (AMPD) within the DSM-5 includes separable components representing general personality dysfunction (Criterion A) and maladaptive personality traits (Criterion B). Some critique Criterion A for accounting for little incremental variance in PD beyond Criterion B. However, Morey et al. (2020) hypothesized that personality dysfunction is a key mechanism through which normal-range traits account for the maladaptive component of personality traits, justifying its inclusion. We sought to replicate and extend this work in a psychiatric sample with mixed methods.

METHOD

In total, 152 participants recruited from mental health clinics completed multiple measures of personality dysfunction and normal-range and maladaptive traits.

RESULTS

Replication was only partially achieved. The degree of incremental prediction of maladaptive traits and the extent to which personality dysfunction explained the relations between normal-range and maladaptive traits varied significantly across traits, and those effects that reached significance were small in magnitude. Removing variance due to personality dysfunction reduced intercorrelations among maladaptive traits by only a small amount.

CONCLUSION

Counter to Morey et al. (2020), our results failed to support maladaptive traits as composites of normal-range traits and personality dysfunction, suggesting that other methods of distinguishing personality pathology severity and style are needed.

Structure of Pathological Personality Traits Through the Lens of the CAT-PD Model

Personality pathology is increasingly conceptualized within hierarchical, dimensional trait models. The Comprehensive Assessment of Traits Relevant to Personality Disorders (CAT-PD) is a pathological-trait measure with potential to improve on currently prevailing instruments because it has wider content coverage; however, its domain-level structure, which is of scientific and clinical interest, is not established. In this study, we investigated the structure and construct validity of the CAT-PD's domain level to facilitate wider use of the measure. We estimated five- and six-factor models with exploratory factor analysis in a pooled sample of eight independent subsamples (N = 3,987) and found that both models fit the data well; each had interpretable factors that were invariant across gender, sample type, and Black/White racial groups; and the factors had good convergent validity with other measures of maladaptive traits, Big Five personality, and interpersonal problems. Our results support the validity of the CAT-PD for assessing multiple levels of the pathological trait hierarchy.

Construct and criterion validity of the HiTOP spectra to predict dimensional and categorical somatization in a large non-western sample

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a phenotypic data-driven framework for the classification of psychopathology. We tested the construct and criterion validity of the HiTOP spectra measured by the Personality Inventory for DSM-5 (PID-5) using exploratory structural equation modeling (ESEM) and hierarchical regressions both to predict somatic symptom and related disorders (SSRD) and a somatization factor. The case-control study used hierarchical logistic regressions to distinguish 257 cases with SSRD from 1007 healthy controls by both the maladaptive and the temperament factors. The extracted factors were also used in hierarchical linear regressions to predict the dimensional somatization factor. The seven temperament factors explained more variance above and beyond the five maladaptive factors when predicting SSRD (pseudo R2 = 0.169 to 0.266 versus 0.125 to 0.196; change in pseudo R2 = 0.055 to 0.087 versus 0.011 to 0.017). The temperament factors also explained more variance above and beyond the maladaptive factors when predicting the somatization factor (R2 = 0.392 versus 0.269; change in R2 = 0.146 versus 0.023). Although the HiTOP spectra measured by PID-5 are significant structures related to the categorical and dimensional measurements of somatoform, our findings highlight potential problems with both the construct and criterion validity of the HiTOP spectra.

Development and Validation of the Certainty About Mental States Questionnaire (CAMSQ): A Self-Report Measure of Mentalizing Oneself and Others

The Certainty About Mental States Questionnaire (CAMSQ) is a self-report measure of the perceived capacity to understand mental states of the self and others (i.e., mentalizing). In two studies (total N = 1828), we developed the CAMSQ in both English and German as a two-dimensional measure of Self- and Other-Certainty, investigated associations with other measures of mentalizing, and explored relationships to personality functioning and mental health. The CAMSQ performed well in terms of convergent and discriminant validity, internal consistency, test-retest reliability, and measurement invariance across the United States and Germany. The present research indicates that the CAMSQ assesses maladaptive forms of having too little or too much certainty about mental states (consistent with hypomentalizing and hypermentalizing). A psychologically adaptive profile of perceived mentalizing capacity appears to be characterized by high Self-Certainty that exceeds Other-Certainty, suggesting that imbalances between Self-Certainty and Other-Certainty (Other-Self-Discrepancy) play an important role within personality pathology.

Dimensional models of personality disorders: Challenges and opportunities

Categorical models of personality disorders have been beneficial throughout psychiatric history, providing a mechanism for organizing and communicating research and treatment. However, the view that individuals with personality disorders are qualitatively distinct from the general population is no longer tenable. This perspective has amassed steady criticism, ranging from inconsequential to irreconcilable. In response, stronger evidence has been accumulated in support of a dimensional perspective that unifies normal and pathological personality on underlying trait continua. Contemporary nosology has largely shifted toward this dimensional perspective, yet broader adoption within public lexicon and routine clinical practice appears slow. This review focuses on challenges and the related opportunities of moving toward dimensional models in personality disorder research and practice. First, we highlight the need for ongoing development of a broader array of measurement methods, ideally facilitating multimethod assessments that reduce biases associated with any single methodology. These efforts should also include measurement across both poles of each trait, intensive longitudinal studies, and more deeply considering social desirability. Second, wider communication and training in dimensional approaches is needed for individuals working in mental health. This will require clear demonstrations of incremental treatment efficacy and structured public health rebates. Third, we should embrace cultural and geographic diversity, and investigate how unifying humanity may reduce the stigma and shame currently generated by arbitrarily labeling an individual's personality as normal or abnormal. This review aims to organize ongoing research efforts toward broader and routine usage of dimensional perspectives within research and clinical spaces.

Validation of the Personality Inventory for DSM-5–Brief Form (PID-5-BF) with Iranian University Students and Clinical Samples: Factor Structure, Measurement Invariance, and Convergent, Discriminant, and Known-Groups Validity

The Personality Inventory for DSM-5, Brief Form (PID-5-BF) was developed to assess DSM-5's Alternative Trait Model for Diagnosing Personality Disorders (AMPD). This study aimed to examine the factor structure, internal consistency, measurement invariance, and convergent, discriminant, and known-group validity of the Persian PID-5-BF with 941 university students (aged 18-67, M age= 28.36, SD = 9.09, 39.1% males) and 178 male from a clinical (aged 18-60, M age= 33.77, SD = 10.60) sample in Iran. Confirmatory factor analyses supported the five-factor model in both groups, being fully and partially invariant across gender and study groups, respectively. PID-5-BF subscales were internally consistent, yielded expected associations with other personality variables, and differentiated the student sample from the clinical group, supporting the measure's convergent, discriminant, and known-group validity. Our results indicated that the PID-5-BF holds promise as a screening measure of dimensional maladaptive personality traits in Iranian students and clinical samples.

Development and Validation of a German Interpersonal Sensitivities Circumplex (ISC-G)

Abstract. The Interpersonal Sensitivities Circumplex (ISC) assesses individual differences in sensitivities to aversive interpersonal behaviors. In this research (total N = 1,519), we developed and validated a German adaptation of the ISC (ISC-G) and extended the nomological net of interpersonal sensitivity as a construct. Using the structural summary method, we investigated associations with self- and informant reports of adaptive (interpersonal) personality traits as well as self-reported personality functioning, maladaptive personality traits, childhood trauma, and hypersensitivity. Replicating and extending previous findings with the ISC, the present research sheds light on the interplay between different personality traits and the perception of others’ interpersonal behavior. Results suggested that individuals report experiencing interpersonal behavior opposite to their own self-description in terms of agency and communion as aversive. This oppositional pattern was most pronounced for antagonistic vs. agreeable traits/behaviors. We discuss these results in the context of research on personality pathology.

Classification and assessment of fear and anxiety in personality and psychopathology

We examine fear and anxiety in the context of structural models of personality (the five-factor model, or FFM) and psychopathology (the Hierarchical Taxonomy of Psychopathology, or HiTOP); we also highlight important issues related to their assessment. Anxiety is a sustained, future-oriented response to potential threat. Trait measures of anxiety represent a core facet within the broader domain of neuroticism in the FFM. Anxiety-related symptoms are indicators of the distress subfactor within the internalizing spectrum in HiTOP. In contrast, fear is a brief, present-focused response to an acute threat. We distinguish between two ways of assessing individual differences in fear. The first type assesses phobic responses to specific stimuli. Phobia measures are moderately correlated with measures of neuroticism in the FFM and define the fear subfactor of internalizing in HiTOP. The second type assesses individual differences in harm avoidance versus risk taking. Measures of risk taking (i.e., low fear) are moderately related to disinhibition/low conscientiousness and antagonism/low agreeableness in the FFM and are indicators of the externalizing superspectrum in HiTOP.

Mapping established psychopathology scales onto the Hierarchical Taxonomy of Psychopathology (HiTOP)

The Hierarchical Taxonomy of Psychopathology (HiTOP) organizes phenotypes of mental disorder based on empirical covariation, offering a comprehensive organizational framework from narrow symptoms to broader patterns of psychopathology. We argue that established self-report measures of psychopathology from the pre-HiTOP era should be systematically integrated into HiTOP to foster cumulative research and further the understanding of psychopathology structure. Hence, in this study, we mapped 92 established psychopathology (sub)scales onto the current HiTOP working model using data from an extensive battery of self-report assessments that was completed by community participants and outpatients (N = 909). Content validity ratings of the item pool were used to select indicators for a bifactor-(S-1) model of the p factor and five HiTOP spectra (i.e., internalizing, thought disorder, detachment, disinhibited externalizing, and antagonistic externalizing). The content-based HiTOP scales were validated against personality disorder diagnoses as assessed by standardized interviews. We then located established scales within the taxonomy by estimating the extent to which scales reflected higher-level HiTOP dimensions. The analyses shed light on the location of established psychopathology scales in HiTOP, identifying pure markers and blends of HiTOP spectra, as well as pure markers of the p factor (i.e., scales assessing mentalizing impairment and suspiciousness/epistemic mistrust).

Cross-cultural Study of the Personality Inventory for the DSM-5 (PID-5) across the Portuguese and the United Arab Emirates (UAE) Community and Clinical Populations

Aims

The present paper focused on compare the PID-5 mean score levels across two matched community and clinical samples of Portugal and the UAE.

Background

The generalizability and universality of the Alternative Model of Personality Disorders has been thoroughly studied through the Personality Inventory for DSM-5 (PID-5) across countries and languages. However, studies comparing Western and Middle Eastern countries are still limited, in particular those who assess the PID-5 measurement invariance.

Objectives

We examined measurement invariance of the PID-5 scales across matched Emirati and Portuguese clinical and nonclinical groups, as well as compare and contrast the PID-5 mean score levels across both countries and samples.

Methods

The Arabic and the Portuguese versions of the PID-5 was administered to Emirati community participants (N = 300, 80% women and 20% men, M_age = 27.95) which were matched with Portuguese community participants (N = 300, 80.3% women and 19.7% men, M_age = 28.96), as well as clinical participants of the UAE (N = 150, 61.3% women and 38.7% men, M_age = 31.29) and Portugal (N = 150, 52% men and 48% women, M_age = 44.97). We examined measurement invariance through an unrestricted Factor Analysis based program, and mean scores levels were compared and analyzed.

Results

Our findings supported the PID-5 measurement invariance across the Emirati and Portuguese clinical samples pointing to the universality and generalizability of the Alternative Model of Personality Disorders. The Emirati psychiatric sample exhibited somehow higher results than the Portuguese psychiatric participants, albeit the small effect size for most of the PID-5 scales.

Conclusion

Further research is needed to examine the applicability of the PID-5 across non-clinical representative samples of Portugal and the UAE, and other Middle Eastern countries.

Cross-Cultural Measurement Invariance in the Personality Inventory for DSM-5✰

The validity of cross-cultural comparisons of test scores requires that scores have the same meaning across cultures, which is usually tested by checking the invariance of the measurement model across groups. In the last decade, a large number of studies were conducted to verify the equivalence across cultures of the dimensional Alternative Model of Personality Disorders (DSM-5 Section III). These studies have provided information on configural invariance (i.e., the facets that compose the domains are the same) and metric invariance (i.e., facet-domain relationships are equal across groups), but not on the stricter scalar invariance (i.e., the baseline levels of the facets are the same), which is a prerequisite for meaningfully comparing group means. The present study aims to address this gap. The Personality Inventory for DSM-5 (PID-5) was administered to five samples differing on country and language (Belgium, Catalonia, France, Spain, and Switzerland), with a total of 4,380 participants. Configural and metric invariance were supported, denoting that the model structure was stable across samples. Partial scalar invariance was supported, being minimal the influence of non-invariant facets. This allowed cross-cultural mean comparisons. Results are discussed in light of the sample composition and a possible impact of culture on development of psychopathology.

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

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

Assessing Maladaptive Personality in the Forensic Context: Development and Validation of the Personality Inventory for DSM-5 Forensic Faceted Brief Form (PID-5-FFBF)

The current study proposes an adaptation of the PID-5 to assesses maladaptive personal traits in forensic settings. Specifically, we adapted the item set of the PID-5 Faceted Brief Form (PID-5-FBF) to the forensic context and validated the resulting PID-5 Forensic Faceted Brief Form (PID-5-FFBF) using self- and informant-reports of 199 male prisoners. Exploratory factor analyses suggested a four-factor solution comprising Antagonism, Detachment, Disinhibited Aggression, and Insecurity. Antagonism and Detachment were very similar to the domains with the same name from the five-factor solution of the PID-5. Insecurity conceptually resembled Negative Affectivity. Disinhibited Aggression represented a forensically highly relevant composition of Antagonism, Disinhibition, and Negative Affectivity. We report results for this four- and the canonical five-factor solution throughout the manuscript. The PID-5-FFBF domains showed convergent associations with the corresponding Big Five personality traits. Furthermore, the PID-5-FFBF domains were differentially correlated with indicators of psychological adjustment and forensically relevant outcomes such as institutional misbehavior and risk for reoffending. In particular, Insecurity was associated with lower levels of psychological adjustment, while Antagonism and Disinhibited Aggression were associated with higher levels of institutional misbehavior and risk for reoffending. These findings provide initial evidence for the validity and utility of the PID-5-FFBF in forensic settings.

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

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

Psychometric Properties of the Personality Inventory for DSM-5 in a Romanian Community Sample

The Personality Inventory for DSM-5 (PID-5) evaluates 25 maladaptive personality traits proposed in the Alternative Model of Personality Disorders. The questionnaire has been extensively investigated and validated in several languages. The current research sought to examine the psychometric properties of the instrument in a sample of nonclinical Romanian participants (N = 1276). Results indicated excellent internal consistency for the domain level, and very good reliability for the facet level. The assumption of unidimensionality was supported at both the domain and facet levels, apart from Risk Taking. Two domain scoring methods were also compared. One of them takes into consideration all the 25 lower order facets, whereas the other uses only 15 facets. Results show that mean differences across the two scoring methods were small, except for Disinhibition. Moreover, confirmatory factor analyses revealed slightly better fit indices for the model which uses 15 facets only. Lastly, the hierarchical structure of maladaptive personality traits was explored. Results are discussed in the light of previous literature.

Development and psychometric evaluation of an informant form of the 20-item Toronto alexithymia scale

OBJECTIVE

The alexithymia personality construct encompasses difficulties identifying and describing feelings, restricted imaginal processes, and an externally oriented cognitive style. The construct was derived initially from observations of patients with classic psychosomatic diseases. The self-report 20-item Toronto Alexithymia Scale (TAS-20) is the most frequently used measure to assess alexithymia. A concern associated with the TAS-20 is whether individuals can accurately self-report difficulties identifying and describing feelings if they are deficient in those abilities. To address this issue, we sought to develop and validate an informant form (version) of the TAS-20, the 20-item Toronto Alexithymia Scale - Informant Form (TAS-20-IF).

METHOD

We employed a three-phase methodological strategy. In the first phase, items from the TAS-20 were re-written into a third person version by a team of experts. In the second phase, the "traditional" three-factor structure was tested in the TAS-20-IF using confirmatory factor analysis in a large sample of young adults (N = 857). The third phase was conducted with another sample (N = 430) composed of "informants" (n = 215), who completed the TAS-20-IF, and "targets" (n = 215), who completed the TAS-20 (informants were nominated by the targets).

RESULTS

The psychometric properties (items and scales) of both versions were adequate and the three-factor structure of the TAS-20-IF was supported; the correlation between the two versions was statistically significant and the factor structures were similar.

CONCLUSION

Although further research is needed to replicate these findings, especially in clinical samples, the results support the reliability and validity of the TAS-20-IF.

Psychometric Properties of the Independent 36-Item PID5BF+M for ICD-11 in the Czech-Speaking Community Sample

Background: Empirical soundness and international robustness of the PID5BF+M, a shortened version of the PID-5 developed for simultaneous evaluation of maladaptive personality traits in the DSM-5 AMPD and ICD-11 models for personality disorders, was recently confirmed in 16 samples from different countries. Because the modified PID5BF+ scale (36 items) was extracted from the complete 220-item PID-5, an independent evaluation of psychometric properties of a stand-alone PID5BF+M is still missing. Objectives: The present study evaluated the validity and reliability of the 36-item PID5BF+M in comparison with the extracted version from the original PID-5. It also assessed associations between the Borderline Pattern qualifier and trait domain qualifiers. Methods: Two non-clinical samples meeting the inclusion criteria were employed in the study. Sample 1 (n = 614) completed the 220-item PID-5; Sample 2 (n = 1,040) completed the independent 36-item PID5BF+M. Participants were from all 14 regions of the Czech Republic. The Borderline Pattern qualifier was evaluated using a shortened IPDEQ screener. Results: The proposed latent structure of the independent PID5BF+M was confirmed, with an exception of the Disinhibition domain. The results confirmed good internal consistency and test-retest reliability of the measure, as well as some support for the measurement invariance of the independent PID5BF+M in comparison with the extracted version from the original PID-5. Significant associations between the Negative affectivity, Disinhibition, and Psychoticism qualifiers and the IPDEQ items for the emotionally unstable personality disorder of both impulsive and borderline types confirmed good predictive validity of the PID5BF+M in pursuing borderline psychopathology within the ICD-11 model. Conclusions: The independent PID5BF+M was found to be a valid and reliable tool for evaluation of the ICD-11 trait model. However, the Disinhibition domain deserves further investigation in clinical samples as well as in international community samples.

Development of a Short and ICD-11 Compatible Measure for DSM-5 Maladaptive Personality Traits Using Ant Colony Optimization Algorithms

While Diagnostic and Statistical Manual of Mental Disorders–Fifth edition (DSM-5) Section III and ICD-11 (International Classification of Diseases 11th–Revision) both allow for dimensional assessment of personality pathology, the models differ in the definition of maladaptive traits. In this study, we pursued the goal of developing a short and reliable assessment for maladaptive traits, which is compatible with both models, using the item pool of the Personality Inventory for DSM-5 (PID-5). To this aim, we applied ant colony optimization algorithms in English- and German-speaking samples comprising a total N of 2,927. This procedure yielded a 34-item measure with a hierarchical latent structure including six maladaptive trait domains and 17 trait facets, the “Personality Inventory for DSM-5, Brief Form Plus” (PID5BF+). While latent structure, reliability, and criterion validity were ascertained in the original and in two separate validation samples (n = 849, n = 493) and the measure was able to discriminate personality disorders from other diagnoses in a clinical subsample, results suggest further modifications for capturing ICD-11 Anankastia.

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 assessment of personality pathology in adolescence from the perspective of the Alternative DSM-5 Model for Personality Disorder

Applying personality disorder diagnosis to adolescents is still a controversial topic. Notwithstanding there is now general agreement that personality disorders have its roots in childhood and adolescence, skepticism with regard to personality disorder diagnoses in adolescence seem to continue among clinicians. The aim of the present review is to summarize the available emerging literature on the assessment of personality pathology in adolescence according to the Alternative DSM-5 Model for Personality Disorders (AMPD). Specifically, we will provide an overview of the available instruments for assessing AMPD Criterion A and Criterion B, with a particular focus on their measurement properties in adolescence. Finally, suggestions for future researches are provided.

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

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

An Overview of the DSM-5 Alternative Model of Personality Disorders

Authoritative classification systems for psychopathology such as the DSM and ICD are shifting toward more dimensional approaches in the field of personality disorders (PDs). In this paper, we provide a brief overview of the dimensionally oriented DSM-5 alternative model of PDs (AMPD). Since its publication in 2013, the AMPD has inspired a substantial number of studies, underlining its generative influence on the field. Generally speaking, this literature illustrates both the reliability and validity of the constructs delineated in the AMPD. The literature also illustrates empirical challenges to the conceptual clarity of the AMPD, such as evidence of substantial correlations between indices of personality functioning (criterion A in the AMPD) and maladaptive personality traits (criterion B in the AMPD). Key future directions pertain to linking the AMPD literature with applied efforts to improve the lives of persons who suffer from PDs, and surmounting challenges germane to the evolution of the DSM itself.

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

PURPOSE OF REVIEW

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

RECENT FINDINGS

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

Tracking Psychopathy in Female Italian Inmates: The Role of the DSM-5 Alternative Model of Personality Disorders Dysfunctional Personality Domains

OBJECTIVE

The present study aimed at testing the relationships between measures of psychopathy and measures of the DSM-5 Alternative Model of Personality Disorders (AMPD) domains in a sample of female offenders who were serving their sentences in Italian prisons.

METHOD

Thirty-eight Italian adult female inmates were underwent the Italian versions of the Psychopathy Checklist-Revised (PCL-R) and of the Personality Inventory for DSM-5-Informant Report Form (PID-5-IRF).

RESULTS

According to MM robust regression analysis results, high scores on the PID-5-IRF Disinhibition domain scale and low scores on the PID-5-IRF Anxiousness trait scale were significant and substantial predictors of the PCL-R total score.

CONCLUSIONS

As a whole, our findings support the hypothesis that assessing the DSM-5 AMPD domains (and traits) may be important for tracking psychopathy in female inmates.
