RESUMO
The goal of this study was to compare the predictive validity of the alternative model for personality disorders (AMPD) versus the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Section II categorical model regarding clinician judgments about mental health outcomes. To do so, we instructed a national sample of 136 mental health professionals to provide clinical judgments on a random subset of four (out of a possible 12) case vignettes. For each case, they made a variety of diagnostic judgments corresponding to each model, as well as clinical outcome judgments (e.g., prognosis). Our analyses included hierarchical and individual regressions to compare the predictive value of each diagnostic system toward these clinical outcome judgments. We found that the AMPD predictors consistently added unique variance beyond the Section II predictors, whereas the Section II predictors were rarely incremental above the AMPD. Further, the AMPD judgments predicted outcome judgments very consistently (98.3% of regressions) compared to the Section II predictors (70% of regressions), and the single Criterion A judgment (level of personality functioning) was the strongest overall predictor. Finally, the categorical borderline personality disorder diagnoses from the two systems performed similarly in predicting clinical outcomes and agreed in 79% of cases. We interpreted our results to suggest that the AMPD is at least as effective, and by some measures more effective, than the DSM-5 categorical model at predicting clinician's judgment of outcomes in clinical cases. We conclude by discussing the value of this evidence in relation to the broader AMPD literature, as well as possible paths forward for the diagnosis of personality disorders.

RESUMO
Coherence in the science and practice of mental health assessment depends upon a tight connection between psychopathology concepts that are used and the way those concepts are operationalized and defined. In contrast, the use of the same word to mean more than one thing contributes to incoherence, inefficiency, and confusion. In this paper, we review three possible meanings of the word "dimension" as it relates to the assessment of psychopathology and describe how the indiscriminate use of this word has caused confusion in the general context of the transition to a more evidence-based approach to mental health diagnosis. We attempt to disambiguate the term "dimension" by demarcating three concepts that can be distinguished based on different empirical standards: continuous variables, unidimensional dimensions, and distinct dimensions.

In this study, we explored the temporal stability of the Personality Assessment Inventory (PAI), which has not been comprehensively reexamined since it was first published. Our three specific aims were to determine the utility of PAI indicators of basic protocol validity (inconsistent responses [ICN] and highly unusual/unlikely responses [INF]) in identifying suspect responding; calculate the stability coefficients for each PAI scale and subscale across 3-, 6-, and 9-week spans; and explore whether profile stability across four measurements could be prospectively predicted. We administered the PAI to a sample of undergraduates (N = 579) at four separate timepoints. ICN and INF effectively identified likely attriters and inconsistent responders. All PAI full scales and subscales evidenced good test-retest reliability, with some small exceptions. Finally, all PAI clinical scales were correlated with profile instability although many of these correlations were no longer significant when controlling for mean clinical elevation of the profile. We interpreted these results as evidence for the utility of PAI validity scales, the temporal reliability of the PAI, and the role of psychopathology in response variability over time. We also discussed some preliminary evidence that this variability can be prospectively predicted, suggesting that it in part reflects substantive changes rather than random error variance.
RESUMO
Attention Deficit Hyperactivity Disorder is a relatively common and often disabling disorder in adults. However, feigning ADHD symptomatology is both easy and potentially common. We explored the most effective strategies for A) identifying individuals who had been diagnosed with ADHD based on existing PAI symptom indicators, and B), discriminating between feigned and genuine ADHD symptoms using PAI negative distortion indicators. Our sample consisted of 463 college aged participants who had been diagnosed with ADHD (n = 60), were asked to feign ADHD (n = 71), and a control group (n = 333). Self-reported diagnosis and successful feigning were corroborated by the CAARS-S: E scale. We first compared two PAI-derived ADHD indicators to determine which best differentiated between our ADHD and Control groups. Next, we compared seven negative distortion indicators to determine which could best distinguish between real and feigned ADHD symptoms. Our results revealed that the PAI-ADHD scale was the most effective symptom indicator. Further, the Negative Distortion Scale (NDS) was the most effective for identifying feigners. When assessing ADHD based on the PAI, the PAI-ADHD scale appears promising as an indicator of symptomatology, while the NDS appears useful to rule-out feigning.
RESUMO
We tested the predictive validity of personality disorder (PD) indicators at different levels of aggregation, ranging from general PD severity to PD syndrome scales to individual PD criteria. We compared the predictive validity of models on these levels based on interview data on all 78 DSM-IV PD criteria, by using 19 outcome scales in three different samples (N = 651, N = 552, and N = 1,277). We hypothesized that criteria of personality pathology yield a significant increase in predictive validity compared with scales that are aggregated at the syndrome- or general severity-level. We assessed out of sample performance of predictive models in a repeated cross-validation design using regularized linear regression and regression forest algorithms. We observed no significant difference in predictive performance between models trained at the item-level and models trained on scale-level data. We further tested the predictive performance of the trained linear models across samples on outcome measures shared between samples and inspected models for criteria-level information they relied on to make predictions. Our results suggest that little predictive variance is lost when interview items assessing DSM-IV PD criteria are aggregated to dimensional PD scales.

One barrier to fully understanding and treating the interpersonal difficulties associated with a variety of psychiatric disorders is a current lack of suitable methodology, which aligns with contemporary interpersonal theory and offers a comprehensive assessment of interpersonal judgment. Specifically, no standardized behavioral interpersonal assessment exists that assesses the accuracy and biases of both interpersonal perceptions and anticipated reactions in a dyadic interaction. The present study presents the development and initial validation of a novel methodology, the Video-based Interpersonal Behavioral Evaluation (VIBE), which (a) utilizes a dynamic (i.e., video-based) behavioral assessment method, (b) assesses the accuracy and biases of both interpersonal perceptions and anticipated reactions, and (c) aligns with interpersonal theory and the structure of the interpersonal circumplex. The VIBE is anticipated to better direct research efforts investigating the interpersonal judgments of individuals with a variety of clinical presentations and ultimately aid in the development of more specifically targeted treatment interventions.

OBJECTIVES: This study examined psychometric properties of the Polish adaptation of a Self-Report Form of the DSM-5 Level of Personality Functioning Scale (LPFS-SR). It is a scale designed to measure general impairment, jointly with a detailed assessment of distinguished components of personality functioning characterized in terms of disturbances in self (identity and self-direction) and interpersonal (empathy and intimacy) functioning - Criterion A in the DSM-5 Alternative Model for Personality Disorders (AMPD). METHODS: The study involved a non-clinical sample of N = 242 adults (52.9% female; Mage = 30.63 years; SDage = 11.81 years). To provide an evaluation of the criterion validity, Personality Inventory for DSM-5 (PID-5), Personality Inventory for ICD-11 (PiCD), Level of Personality Functioning Scale - Brief Form 2.0 (LPFS-BF 2.0), and Big Five Inventory-2 (BFI-2) were administered. RESULTS: Our data supported that identity, self-direction, intimacy, and empathy components of the LPFS-SR can be characterized by a single, global dimension of personality dysfunction, consistent with the assumption that DSM-5 Criterion A is a relatively homogeneous construct. The LPFS-SR showed good reliability estimates and demonstrated conceptually sound associations with the PD severity index and related measures of personality functioning. Moreover, all the LPFS-SR components manifested at least partial distinction from maladaptive personality traits (i.e., Criterion B in the DSM-5 AMPD). CONCLUSIONS: These findings provide support for the validity of the Polish adaptation of the LPFS-SR as an operationalization of impairment in the core and common features of personality pathology described in the DSM-5 alternative model.

BACKGROUND: Numerous theories posit different core features to borderline personality disorder (BPD). Recent advances in network analysis provide a method of examining the relative centrality of BPD symptoms, as well as examine the replicability of findings across samples. Additionally, despite the increase in research supporting the validity of BPD in adolescents, clinicians are reluctant to diagnose BPD in adolescents. Establishing the replicability of the syndrome across adolescents and adults informs clinical practice and research. This study examined the stability of BPD symptom networks and centrality of symptoms across samples varying in age and clinical characteristics. METHODS: Cross-sectional analyses of BPD symptoms from semi-structured diagnostic interviews from the Collaborative Longitudinal Study of Personality Disorders (CLPS), the Methods to Improve Diagnostic Assessment and Service (MIDAS) study, and an adolescent clinical sample. Network attributes, including edge (partial association) strength and node (symptom) expected influence, were compared. RESULTS: The three networks were largely similar and strongly correlated. Affective instability and identity disturbance emerged as relatively central symptoms across the three samples, and relationship difficulties across adult networks. Differences in network attributes were more evident between networks varying both in age and in BPD symptom severity level. CONCLUSIONS: Findings highlight the relative importance of affective, identity, and relationship symptoms, consistent with several leading theories of BPD. The network structure of BPD symptoms appears generally replicable across multiple large samples including adolescents and adults, providing further support for the validity of the diagnosis across these developmental phases.

Past psychiatric diagnoses are central to patient case formulation and prognosis. Recently, alternative classification models such as the Hierarchical Taxonomy of Psychopathology (HiTOP) proposed to assess traits to predict clinically-relevant outcomes. The current study directly compared personality traits and past diagnoses as predictors of future mental health and functioning in three independent, prospective samples. Regression analyses found that personality traits significantly predicted future first onsets of psychiatric disorders (ΔR2=06-.15), symptom chronicity (ΔR2=.03-.06), and functioning (ΔR2=.02-.07), beyond past and current psychiatric diagnoses. Conversely, past psychiatric diagnoses did not provide an incremental prediction of outcomes when personality traits and other concurrent predictors were already included in the model. Overall, personality traits predicted a variety of outcomes in diverse settings, beyond diagnoses. Past diagnoses were generally not informative about future outcomes when personality was considered. Together, these findings support the added value of personality traits assessment in case formulation, consistent with HiTOP model.
RESUMO
Criterion A, as represented by Level of Personality Functioning (LPF), offers a means by which to conceptualize the core impairment in self and interpersonal functioning that distinguishes personality disorder (PD) from other forms of psychopathology. One of the most widely cited criticisms of the current Section II in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition categorical diagnostic system is the high level of comorbidity among the categorical PD diagnoses. The Section III alternative Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition model for PDs (AMPD) addresses this problem by assessing the commonalities of the PDs using a single severity continuum, represented in the AMPD by the Level of Personality Functioning Scale (LPFS), which comprises both self and interpersonal pathology. Since its initial introduction, the LPFS has generated an expansive literature base and has also seen significant advancements in its measurement, including both semistructured and self-report methods. Such studies have generally demonstrated that the LPFS can be rated reliably, across both experienced and inexperienced raters, and demonstrates strong validity as evidenced by associations with relevant criterion variables and demonstrations of predictive and clinical utility. This review offers a brief history of the conceptualization and development of Criterion A and the LPFS, describes the major advancements in its measurement, and provides a summary of the status of the empirical literature regarding Criterion A's structure, reliability, and validity.

BACKGROUND: Identity disturbances are a common feature of personality pathology and BPD. The Self-Reference Effect paradigm is a method used to measure the impact of self-relevant processing on encoding/memory, whereby self-relevant information is typically advantaged in cognitive processes. We postulated that difficulties with identity might impede the process by which one encodes self-relevant information. Based on this reasoning, we predicted that high levels of identity disturbance could be associated with atypical impact of the SRE. METHODS: Undergraduate participants were randomized into one of three groups where they were exposed to 60 trait adjectives for seven seconds each. Depending on condition, participants either indicated whether a word was/wasn't capitalized (Capitalization condition), whether it was a good synonym for "openness" (Synonyms condition), or whether it described them as a person (Self-reference condition). After a brief delay, all participants were asked to recall as many of the 60 words as possible. Finally, we measured identity disturbance using the Borderline Features-Identity Problems (BOR-I) scale from the Personality Assessment Inventory. RESULTS: We found significant but modest correlations between Recall and scores on the BOR-I subscale in the Self-Reference condition, but not the two control conditions. Contrary to expectations, the interaction between BOR-I and Condition was not a significant predictor of Recall, suggesting that identity disturbance did not significantly moderate the SRE. CONCLUSIONS: While our primary hypothesis was not supported, there is a need for multimethod approaches to studying personality pathology. Future research should continue to examine the extent to which behavioral paradigms like the SRE might be useful indicators of identity disturbance/personality pathology, with an emphasis on the use of clinical populations.
RESUMO
OBJECTIVE: The DSM-5 Alternative Model of Personality Disorders distinguishes core personality dysfunction common to all personality pathology from maladaptive traits that delineate specific variants of disorder. Previous research shows the convergence between maladaptive and normal range trait domains as well as substantial correlations between maladaptive traits and core dysfunctions, leading some to conclude that personality traits and dysfunction are redundant. This study sought to examine the potential utility of the concept of core dysfunctions as a means of clarifying the nature of the relationship between maladaptive and normal-range traits. METHOD: Three nonclinical samples (n = 178, 307, and 1,008) were evaluated for personality dysfunction, maladaptive traits, and normal-range traits using different measures. RESULTS: Results indicated that: (1) normal trait domains and core dysfunction contribute independently to understanding maladaptive traits; (2) the correlation of a normal trait domain with its putative maladaptive equivalent is consistently accounted for in part by core dysfunction; and (3) the multitrait multimethod matrices of normal and maladaptive personality trait domains demonstrate appreciable discriminant validity problems that are clarified by a consideration of core dysfunction. CONCLUSION: These results suggest that maladaptive traits reflect the distinguishable contributions of core personality dysfunction (problems) and normal-range personality traits (person).

The Hierarchical Taxonomy of Psychopathology (HiTOP) is an empirical-based classification of psychopathology. Detachment is one of the six spectra in the current HiTOP working model. The aim of this study was to develop preliminary scales for the HiTOP Detachment spectrum that can be used in the next phase of developing a comprehensive measure of HiTOP. We had 456 participants from MTurk (Sample 1) and 266 university students (Sample 2) complete an online survey including a pool of 247 Detachment items assessing 15 consensually defined low-order constructs. Using a stepwise procedure involving factor analyses and ant colony optimization methods, we developed seven 8-item scales that capture unipolar facets of Detachment: anhedonia, suspiciousness, social withdrawal, intimacy avoidance, unassertiveness, risk aversion, and restricted affectivity. Three other 8-item scales emerged that tapped into a Maladaptive Extraversion construct (attention-seeking, thrill-seeking, and domineering), which was mostly unrelated to unipolar Detachment in factor analyses. The 10 scales were unidimensional, reliable, and showed some evidence of convergent and discriminant validity. We discuss challenges of assessing Detachment when moving forward with developing a comprehensive measure of HiTOP.

Structural models of personality traits, particularly the five-factor model (FFM), continue to inform ongoing debates regarding what personality attributes and trait domains are central to psychopathy. A growing body of literature has linked the constructs of the triarchic model of psychopathy (boldness, meanness, disinhibition) to the FFM. Recently, researchers developed both item and regression-based measures of the triarchic model of psychopathy using the NEO Personality Inventory-Revised-a popular measure of the FFM. The current study examines the correlates of these two FFM-derived operationalizations of the triarchic model using data from the Collaborative Longitudinal Personality Disorders Study. The two approaches had strong convergent validity coefficients and similar patterns of criterion-related validity coefficients. Meanness related to greater personality pathology characterized by exploitation of others and poor attachment, whereas disinhibition related to indicators of greater negative affect and poor behavioral constraint. Boldness related to reduced negative affect and greater narcissistic personality traits. Although the item and regression-based approaches showed similar patterns of associations with criterion-variables, the item-based approach has some practical and psychometric advantages over the regression-based approach given strong correlations between the meanness and disinhibition scores from the regression approach.

Shortcomings of approaches to classifying psychopathology based on expert consensus have given rise to contemporary efforts to classify psychopathology quantitatively. In this paper, we review progress in achieving a quantitative and empirical classification of psychopathology. A substantial empirical literature indicates that psychopathology is generally more dimensional than categorical. When the discreteness versus continuity of psychopathology is treated as a research question, as opposed to being decided as a matter of tradition, the evidence clearly supports the hypothesis of continuity. In addition, a related body of literature shows how psychopathology dimensions can be arranged in a hierarchy, ranging from very broad "spectrum level" dimensions, to specific and narrow clusters of symptoms. In this way, a quantitative approach solves the "problem of comorbidity" by explicitly modeling patterns of co-occurrence among signs and symptoms within a detailed and variegated hierarchy of dimensional concepts with direct clinical utility. Indeed, extensive evidence pertaining to the dimensional and hierarchical structure of psychopathology has led to the formation of the Hierarchical Taxonomy of Psychopathology (HiTOP) Consortium. This is a group of 70 investigators working together to study empirical classification of psychopathology. In this paper, we describe the aims and current foci of the HiTOP Consortium. These aims pertain to continued research on the empirical organization of psychopathology; the connection between personality and psychopathology; the utility of empirically based psychopathology constructs in both research and the clinic; and the development of novel and comprehensive models and corresponding assessment instruments for psychopathology constructs derived from an empirical approach.
RESUMO
Two of the most widely used self-report measures of impulsivity are the UPPS-P Impulsive Behavior Scale and its shortened version, the SUPPS-P, which currently are limited by their inability to detect careless and/or random responding. The present study develops and cross-validates an inconsistency scale for use with the UPPS-P and SUPPS-P in order to accurately screen for data quality and better detect invalid responding. A total of 443 participants were recruited from Amazon's MTurk online data collection service to serve as the derivation sample and 231 undergraduates were recruited to serve as the cross-validation sample. The inconsistency scale demonstrated good classification accuracy in differentiating between genuine and random protocols and moderated the relationships between the UPPS-P/SUPPS-P and a criterion measure of impulsivity, the Barratt Impulsiveness Scale-11 (BIS-11). Thus, the inconsistency scale shows promise as an indicator of variable response inconsistency for use with both the UPPS-P and SUPPS-P in community and undergraduate research samples.

We critique Roy et al.'s (2020; this issue) approach to characterizing the item-level factor structure of the three scales of the Triarchic Psychopathy Measure (TriPM), in light of the manner in which the TriPM scales were developed, the purposes they were designed to serve, and the growing body of evidence supporting their construct validity. We focus on three major points: (1) The TriPM scales are item-based factor scales - i.e., item sets designed to index broad factors of larger multi-scale (parent) inventories; (2) item-level structural analysis can be useful for representing broad dimensions tapped by such scales, but it cannot be expected to provide an accurate picture of narrower subdimensions (facets) assessed by their parent inventories; and (3) it is critical to consider the nomological networks of the TriPM scales (and other triarchic scale measures) in appraising their effectiveness as operationalizations of the triarchic model constructs. We illustrate the first and second of these points by applying Roy et al.'s analytic approach to the trait scales of the NEO-FFI, which were developed to index broad personality dimensions of the multi-scale NEO-PI-R. We address the third point with reference to the growing body of literature supporting the construct validity of the TriPM scales and demonstrating their utility for advancing an integrative understanding of psychopathy.

Importance: Borderline personality disorder (BPD) has been identified as a strong risk factor for suicidal behavior, including suicide attempts. Delineating specific features that increase risk could inform interventions. Objective: To examine factors associated with prospectively observed suicide attempts among participants in the Collaborative Longitudinal Study of Personality Disorders (CLPS), over 10 years of follow-up, with a focus on BPD and BPD criteria. Design, Setting, and Participants: The CLPS is a multisite, naturalistic, prospective study of adult participants with 4 personality disorders (PDs) and a comparison group of adults with major depressive disorder and minimal PD features. Participants were all treatment-seeking and recruited from inpatient, partial, and outpatient treatment settings across New York, New York, Boston, Massachusetts, New Haven, Connecticut, and Providence, Rhode Island. A total of 733 participants were recruited at baseline, with 701 completing at least 1 follow-up assessment. The cohorts were recruited from September 1996 through April 1998 and September 2001 through August 2002. Data for this study using this follow-up sample (N = 701) were analyzed between March 2019 and August 2020. Main Outcomes and Measures: Participants were assessed annually using semistructured diagnostic interviews and a variety of self-report measures for up to 10 years. Multiple logistic regression analyses were used to examine baseline demographic and clinical risk factors, including BPD and individual BPD criteria, of suicide attempt assessed over 10 years of prospective follow-up. Results: Of the 701 participants, 447 (64%) identified as female, 488 (70%) as White, 527 (75%) as single, 433 (62%) were unemployed, and 512 (73%) reported at least some college education. Of all disorders, BPD emerged as the most robust factor associated with prospectively observed suicide attempt(s) (odds ratio [OR], 4.18; 95% CI, 2.68-6.52), even after controlling for significant demographic (sex, employment, and education) and clinical (childhood sexual abuse, alcohol use disorder, substance use disorder, and posttraumatic stress disorder) factors. Among BPD criteria, identity disturbance (OR, 2.21; 95% CI, 1.37-3.56), chronic feelings of emptiness (OR, 1.63; 95% CI, 1.03-2.57), and frantic efforts to avoid abandonment (OR, 1.93; 95% CI, 1.17-3.16) emerged as significant independent factors associated with suicide attempt(s) over follow-up, when covarying for other significant factors and BPD criteria. Conclusions and Relevance: In the multisite, longitudinal study of adults with personality disorders, identity disturbance, chronic feelings of emptiness, and frantic efforts to avoid abandonment were significantly associated with suicide attempts. Identity disturbance, chronic feelings of emptiness, and frantic efforts to avoid abandonment may be clinically overlooked features of BPD in context of suicide risk assessment. In light of the high rates of BPD diagnostic remission, our findings suggest that these criteria should be independently assessed and targeted for further study as suicide risk factors.

Differential diagnosis of autism spectrum disorder (ASD) among intellectually-able adults often presents a clinical challenge, particularly when individuals present in crisis without diagnostic history. The Personality Assessment Inventory (PAI) is a multiscale personality and psychopathology instrument utilized across clinical settings, but to date there are no published normative data for use of the PAI with adults with ASD. This study provides normative PAI data for adults diagnosed with ASD, with effect size comparisons to the PAI clinical standardization sample and an inpatient sample. Additionally, a discriminant function was developed and cross-validated for identification of ASD-like symptomatology in a clinical population, which demonstrates promise as a screening tool to aid in the identification of individuals in need of specialized ASD assessment.

Much of the research on identifying feigning in psychological assessment has focused on adults with less attention to adolescents. The purpose of the present study is to expand the limited literature on detecting feigning in adolescents using the Personality Assessment Inventory - Adolescent. The study included 114 nonclinical adolescents (ages 15 to 18) recruited from high schools in the Midwest who were randomly assigned to experimental groups: honest nonclinical, uncoached feigning, and coached feigning. 50 randomly selected individuals with depression from the PAI-A clinical standardization sample were included as the honest clinical group. Sample demographics included a mean age of 16.64 years; 51.2% young men, 48.2% young women; 85.4% Caucasian, 6.7% African American, 5.5% Hispanic, and 2.4% Asian. 80% of feigning profiles reported clinical levels of depression. MANOVA results showed strong support for the Rogers Discriminant Function (RDF; d range = 1.85-2.05). The Negative Impression Management (NIM) scale also demonstrated promise (d range = 0.77-1.08), while the smallest effects for detecting feigning were found for the Malingering Index (d range = 0.58-0.70). The negative distortion indices showed good utility in differentiating between groups. Cut-scores and pragmatic implications are presented.
