Momentary assessment of the relations between narcissistic traits, interpersonal behaviors, and aggression.

INTRODUCTION: This study explores the associations among narcissistic traits, interpersonal behaviors, and aggression using repeated, situation-based measurement. We examine narcissism's relations with aggression across three levels of its theorized hierarchy (level 1: narcissism; level 2: grandiose vs. vulnerable narcissism; level 3: antagonism, agentic extraversion, and narcissistic neuroticism). METHODS: Using an experience-sampling approach, the current study examined the effects of narcissism and its finer-grained components on daily affective experiences and aggressive behaviors in the context of interpersonal interactions. Data were collected from 477 undergraduate students who were instructed to complete four prompts a day for ten consecutive days. RESULTS: Narcissism at the global construct level positively predicted multiple indices of episodic aggression (i.e., aggressive temper, aggressive urge, verbal aggression). At the dual-dimension level, grandiose narcissism specifically predicted aggression, and then at the trifurcated level, interpersonal antagonism predicted aggression by itself and in interaction with event-level negative affect. Negative affect consistently exhibited both within- and between-person effects on aggression. CONCLUSION: In real-life social interactions, narcissism dimensions differentially affect the way individuals experience social interactions and process negative affect, and thus in both research and clinical practice, narcissism is best assessed as a heterogeneous, multidimensional construct.

HiTOP Assessment of Externalizing Antagonism and Disinhibition.

This article outlines the Phase 1 efforts of the HiTOP Measure Development group for externalizing constructs, which include disinhibited externalizing, antagonistic externalizing, attention deficit hyperactivity disorder, substance use, and externalizing/maladaptive behaviors. We provide background on the constructs included and the process and issues involved in developing a measure for this diverse range of psychopathology symptoms, traits, and behaviors.

Difficulties with the conceptualization and assessment of Criterion A in the DSM-5 alternative model of personality disorder: A reply to Morey (2019).

The DSM-5 introduced an alternative model of personality disorders that is predicated on the presence of personality dysfunction (Criterion A) and pathological personality traits (Criterion B). Recently, a member of the DSM-5 Personality and Personality Disorder Work Group-Morey-published a measure of Criterion A. Our study (Sleep, Lynam, Widiger, Crowe, & Miller, 2019, this issue) examined the performance of Morey's (2017) Levels of Personality Functioning Scale-Self-Report (LFPS-SR) by testing its factor structure, relations with Axis I and II symptoms, and its incremental validity in predicting traditional personality disorders in comparison to Criterion B traits. In his response, Morey raised a number of issues regarding our examination of the LPFS-SR in relation to its factor structure, discriminant validity, and incremental validity. Moreover, he suggested our approach (i.e., pitting Criterion A vs. B) is emblematic of problems in the field that contributed to the relegating of the AMPD to Section III (on emerging measures and models). In our response, we answer his criticisms. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Rejoinder: A Construct Validity Approach to the Assessment of Narcissism.

In this rejoinder, we comment on Wright's response to our reanalysis and reinterpretation of the data presented by Wright and colleagues. Two primary differences characterize these perspectives. First, the conceptualization of grandiose narcissism differs such that emotional and ego vulnerability, dysregulation, and pervasive impairments are more characteristic of Wright's conception, likely due to the degree to which it is tied to clinical observations. Our conceptualization is closer to psychopathy and describes an extraverted, dominant, and antagonistic individual who is relatively less likely to be found in clinical settings. Second, our approach to construct validation differs in that we take an empirical perspective that focuses on the degree to which inventories yield scores consistent with a priori predictions. The grandiose dimension of the Pathological Narcissism Inventory (PNI-G) yields data that fail to align with expert ratings of narcissistic personality disorder and grandiose narcissism. We suggest that caution should be taken in treating the PNI-G as a gold standard measure of pathological narcissism, that revision of the PNI-G is required before it can serve as a stand-alone measure of grandiose narcissism, and that the PNI-G should be buttressed by other scales when being used as a measure of grandiose narcissism.

Development of a short form of the elemental psychopathy assessment.

The Elemental Psychopathy Assessment (EPA) is a 178-item self-report measure designed to assess the basic elements of psychopathy from a Five-Factor Model perspective: Anger, Arrogance, Callousness, Coldness, Disobliged, Distrust, Dominance, Impersistence, Invulnerable, Manipulation, Opposition, Rashness, Self-Assurance, Self-Centered, Self-Contentment, Thrill-Seeking, Unconcern, and Urgency. The present article reports on the development of a short-form version of the EPA in two large undergraduate samples using item response theory. The validity of the resultant, 72-item, item response theory-derived short form is compared against the validity for the full scale in the undergraduate samples and smaller forensic sample. Results indicate that the 18 subscales of the EPA short form remain relatively reliable, possess an internal structure virtually identical to the full version, and manifest highly similar correlational profiles to a variety of criterion measures. The EPA short form is offered as a viable assessment of psychopathy when assessment time is limited. Implications of these findings are discussed.

An examination of the factor structure of the Elemental Psychopathy Assessment.

The Elemental Psychopathy Assessment (EPA) is a self-report measure designed to assess the basic elements of psychopathy from a Five-Factor Model perspective. Using two large undergraduate samples, the aim of the current study was to further validate this new measure by examining its factor structure and the relations of the factors with established psychopathy measures and externalizing behaviors (Sample 2 only). Exploratory factor analytic results were highly consistent across the two samples and generated a four-factor structure characterized by Antagonism, Emotional Stability, Disinhibition, and Narcissism. These factors converged as expected with factors from alternative self-report conceptualizations of psychopathy and externalizing behaviors. The EPA factors also provided incremental validity in the prediction of the alternative psychopathy measures and externalizing behaviors above and beyond the other psychopathy measures. The stable factor structure and relations with constructs relevant to the study of psychopathy provide further support for the EPA as a stand-alone, comprehensive assessment of psychopathic personality.

An examination of the Dirty Dozen measure of psychopathy: a cautionary tale about the costs of brief measures.

Given substantial interest in the traits conceived of as part of the "Dark Triad"--psychopathy, narcissism, and Machiavellianism--assessment of these traits is of great importance. The Dirty Dozen (DD; Jonason & Webster, 2010) is a brief measure of the Dark Triad constructs that uses 4 items to assess each of these constructs. In the present study, the authors examined the adequacy of the DD's Psychopathy scale by comparing it with established measures of psychopathy in a sample of undergraduates (Sample 1: N = 789) and male prisoners (Sample 2: N = 75). DD's Psychopathy subscale manifested significant correlations with established measures, but the correlations were smaller than those evinced by the existing scales. The results also demonstrated that there is important variance related to interpersonal antagonism and disinhibition that is not assessed by the DD. The authors suggest that caution should be used in relying on the DD as a measure of psychopathy.

Assessment of maladaptive variants of Five-Factor Model traits.

Research has shown that the personality disorders (PDs) bear consistent relations to general models of personality functioning, particularly in relation to the Five-Factor Model (FFM). In addition to suggesting that the PDs might be understood as constellations of traits from the FFM, this research also suggests that these constellations might be used to assess the PDs. The present article reviews previous research using the NEO Personality Inventory-Revised (NEO PI-R; Costa & McCrae, ) to assess disordered personality and discusses some shortcomings of this approach. Next, I detail studies that have used what is known about the relations between the FFM and disordered personality to construct new assessments that are grounded in the basic science of personality but designed to assess the more pathological aspects. Finally, the advantages of this approach are outlined.

Examining the construct validity of the elemental psychopathy assessment.

Lynam and colleagues recently developed a new self-report inventory for the assessment of psychopathy, the Elemental Psychopathy Assessment (EPA). Using a sample of undergraduates (N = 227), the authors examined the construct validity of the EPA by examining its correlations with self and stranger ratings on the Five-Factor Model, as well as self-reported ratings of personality disorders, social cognition, and love styles. The EPA psychopathy scores manifested expected correlations with both self and stranger ratings of the Five-Factor Model, particularly with the domains of Agreeableness and Conscientiousness, and were significantly related to various forms of personality pathology such as narcissism and antisocial personality disorders. The EPA also manifested expected relations with aggressive social cognitions. Finally, the EPA psychopathy scores were correlated with romantic love styles indicative of game playing and infidelity. The current results provide further evidence of the construct validity of the EPA as it manifests relations consistent with the nomological network of psychopathy.

Assessing the basic traits associated with psychopathy: development and validation of the Elemental Psychopathy Assessment.

A new self-report assessment of the basic traits of psychopathy was developed with a general trait model of personality (five-factor model [FFM]) as a framework. Scales were written to assess maladaptive variants of the 18 FFM traits that are robustly related to psychopathy across a variety of perspectives including empirical correlations, expert ratings, and translations of extant assessments. Across 3 independent undergraduate samples (N = 210-354), the Elemental Psychopathy Assessment (EPA) scales proved to be internally consistent and unidimensional, and were strongly related to the original FFM scales from which they were derived (mean convergent r = .66). The EPA scales also demonstrated substantial incremental validity in the prediction of existing psychopathy measures over their FFM counterparts. When summed to form a psychopathy total score, the EPA was substantially correlated with 3 commonly used psychopathy measures (mean r = .81). Finally, in a small male forensic sample (N = 70), the EPA was significantly correlated with scores on a widely used self-report psychopathy measure, disciplinary infractions, alcohol use, and antisocial behavior. The EPA provides an opportunity to examine psychopathy and its nomological network through smaller, more basic units of personality rather than by scales or factors that blend these elements.

Comparing two alternative measures of general personality in the assessment of psychopathy: a test of the NEO PI-R and the MPQ.

This study examined the interrelations between two measures of personality, the Revised NEO Personality Inventory (NEO PI-R; P. T. Costa & R. R. McCrae, 1992) and the Multidimensional Personality Questionnaire (MPQ; Tellegen & Waller, 2008), and their relations with psychopathy in a sample of undergraduates. Results revealed good convergence between conceptually related personality traits; however, the NEO PI-R facets accounted for more variance in the MPQ subscales (mean R(2)=.49) than did MPQ subscales in NEO PI-R facets (mean R(2)=.35). Both accounted for substantial proportions of variance in psychopathy scores, although the NEO PI-R accounted for larger proportions and manifested greater incremental validity when using the broader domains of each measure; the differences decreased when the narrower facets/subscales were used. The results suggest that, although both measures assess psychopathy-related traits, the NEO PI-R provides a more complete description because of its assessment of interpersonal antagonism and the central role of this construct in psychopathy.

Neuroticism, Negative Affect, and Negative Affect Instability: Establishing Convergent and Discriminant Validity Using Ecological Momentary Assessment.

Few investigations have examined the role of affective instability within a broad model of general personality functioning. The present study employed self-report and ecological momentary assessments (EMA) to examine the relations between self-reported Five-Factor Model Neuroticism, EMA average negative affect, and EMA negative affect instability. Results suggest that Neuroticism and negative affect instability are related yet distinct constructs, and that Neuroticism better represents average negative affect across time. Results also suggest that negative affect instability is related to low Agreeableness and specific externalizing facets of Neuroticism, such as Angry Hostility and Impulsiveness. The implications of these findings and potential areas for future research are discussed.
