The growing interest in the study of narcissism has resulted in the development of a number of assessment instruments that manifest only modest to moderate convergence. The present studies adjudicate among these measures with regard to criterion validity. In the 1st study, we compared multiple narcissism measures to expert consensus ratings of the personality traits associated with narcissistic personality disorder (NPD; Study 1; N = 98 community participants receiving psychological/psychiatric treatment) according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.

Impulsivity has been consistently associated with pathological gambling (PG), but the diversity of definitions and measures of impulsivity has led to ambiguity with regard to which indices are independently relevant. Toward clarifying this relationship, the current study examined indices from an array of commonly used impulsivity measures in relation to PG severity in an adult community sample of frequent gamblers (N = 353). These included both survey assessments and behavioral tasks.

There exists substantial debate about how to best assess pathological narcissism with a variety of measures designed to assess grandiose and vulnerable narcissism, as well as the DSM-IV and DSM-5 based conceptualizations of narcissistic personality disorder (NPD). Wright and colleagues published correlations between several narcissism measures (Narcissistic Personality Inventory [NPI]; Pathological Narcissism Inventory [PNI]; Personality Diagnostic Questionnaire [PDQ] NPD) with the traits comprising the DSM-5 Section III personality trait model. In the current study, we examine the agreement manifested by Wright and colleagues' narcissism-DSM-5 trait profiles with expert ratings of the DSM-5 traits most relevant to descriptions of DSM-IV NPD.

Comments on an article by Krueger (see record 2013-45025-008). The current authors appreciate the opportunity to comment on Krueger's article. They remark that as a member of the DSM-5 (American Psychiatric Association, 2013) Personality and Personality Disorders Work Group (PPDWG), he is in a unique position to describe the process surrounding the deliberations of the PPDWG and why their model was placed in Section III.

The Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association, 2013), includes a novel approach to the diagnosis of personality disorders (PDs) in Section III, to stimulate further research with the possibility that this proposal will be included more formally in future DSM iterations. This study provides the 1st test of this proposal in a clinical sample by simultaneously examining its 2 primary components: a system for rating personality impairment and a newly developed dimensional model of pathological personality traits.

Two dimensions of narcissism exist, grandiose and vulnerable, which are thought to be associated with distinctly different patterns of interpersonal behavior. Social network analysis is a way of quantifying and analyzing interpersonal interactions that may prove useful for characterizing the networks associated with these narcissism dimensions. In the current study, participants (N = 148) completed scales assessing both narcissism dimensions and a measure of the five-factor model of personality.

The Psychopathic Personality Inventory (PPI) is a commonly used assessment of psychopathy. Questions have been raised, however, regarding the validity of its Fearless Dominance (FD) factor. In the current study, the correlations manifested by FD and Self-centered Impulsivity (ScI) in relation to external criteria were examined in a sample of gamblers.

Deer antlers are bony appendages that are annually cast and rapidly regrown in a seasonal process coupled to the reproductive cycle. Due to the uniqueness of this process among mammals, we reasoned that a fundamental characterization of antler progenitor cell behavior may provide insights that could lead to improved strategies for promoting bone repair. In this study, we investigated whether white-tailed deer antlerogenic progenitor cells (APC) conform to basic criteria defining mesenchymal stromal cells (MSC).

There has been a substantial increase in the simultaneous study of 3 related constructs--psychopathy, Machiavellianism, and narcissism--since being termed the dark triad (DT; Paulhus & Williams, 2002). Growing interest in the DT has led to the development of 2 short, efficient measures that reduce the number of items typically used from 124 to 12 (Dirty Dozen, or DD; Jonason & Webster, 2010) and 27 (Short Dark Triad, or SD3; Jones & Paulhus, in press), respectively. Using a community sample collected online (N = 287), we examined the convergent, discriminant, incremental, and criterion validity of scores from 2 brief measures of the DT.

Psychopathic traits are typically associated with an array of externalizing behaviors including violent and nonviolent crime and recidivism, substance use, aggression, and sexual coercion. In the current study, we test the hypothesis that psychopathic traits are related to an increased tolerance for physical pain, which may partially account for the relations between psychopathy and antisocial behavior (ASB). Using community participants oversampled for psychopathic traits (N = 104), we found that psychopathic traits, measured using self- and informant reports, manifested small correlations with some measures of physical pain tolerance (tolerance of pressure and electric shock) but not others (tolerance of cold temperature).

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.

Objective: Alcohol misuse is substantially influenced by social factors, but systematic assessments of social network drinking are typically lengthy. The goal of the present study was to provide further validation of a brief measure of social network alcohol use, the Brief Alcohol Social Density Assessment (BASDA), in a sample of emerging adults. Specifically, the study sought to examine the BASDA's convergent, criterion, and incremental validity in relation to well-established measures of drinking motives and problematic drinking.

Despite widespread use, the South Oaks Gambling Screen (SOGS) has been criticized for excessive false positives as an indicator of pathological gambling (PG), and for items that misalign with PG criteria. We examine the relationship between SOGS scores and PG symptoms and convergent validity with regard to personality, mood, and addictive behaviors in a sample of 353 gamblers. SOGS scores correlated r = .

Affective instability (AI) is as a central component of a number of psychiatric disorders, but it has received relatively little empirical attention as an individual construct. The goal of the current study was to study AI in the context of a broad empirical network of relevant constructs and compare its pattern of relations with those generated by trait neuroticism, both of which were assessed using both self- and informant reports. In a sample of 343 college students, the present study examined the correlations generated by an AI factor (derived from a factor analysis of relevant scales) in comparison to neuroticism in relation to personality and etiological and outcome variables.

The most widely used measure of trait narcissism is the Narcissistic Personality Inventory (NPI), which can provide both total and subscale scores. However, with a length of 40 items, this measure may not be ideal in settings in which time or participant attention may limit the types of measures that can be administered. In response, Ames, Rose, and Anderson (2006) created the NPI-16, which provides a shorter, unidimensional measure of the construct.

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.

Personality disorders (PDs) may be better understood in terms of dimensions of general personality functioning rather than as discrete categorical conditions. Personality-trait descriptions of PDs are robust across methods and settings, and PD assessments based on trait measures show good construct validity. The study reported here extends research showing that basic traits (e.

The Five-Factor Narcissism Inventory (FFNI) is a new self-report measure that was developed to assess traits associated with grandiose and vulnerable narcissism from a Five-factor model (FFM) perspective. In a sample of undergraduates (N = 283), the relations among the FFNI scales, grandiose and vulnerable dimensions, and an array of relevant criteria were examined including self- and informant reports of the Big Five domains, measures of the Dark Triad, ratings of the interpersonal circumplex, externalizing and internalizing behaviors and symptoms, and romantic and attachment styles. The FFNI grandiose and vulnerable dimensions demonstrated good convergent and criterion validity.

Personality traits have proved to be consistent and important factors in a variety of externalizing behaviors including addiction, aggression, and antisocial behavior. Given the comorbidity of these behaviors with pathological gambling (PG), it is important to test the degree to which PG shares these trait correlates. In a large community sample of regular gamblers (N=354; 111 with diagnoses of pathological gambling), the relations between measures of two major models of personality - Big Three and Big Five - were examined in relation to PG symptoms derived from a semi-structured diagnostic interview.

The Five-Factor model is one of the most popular models of general personality but recently a competing model, the HEXACO, has been put forth as an alternative. In the current study, we compare the two models by examining the interrelations between their primary measures, the Revised NEO Personality Inventory (NEO PI-R) and the Revised HEXACO Personality Inventory (HEXACO-PI-R), and their relations with psychopathy in a sample of undergraduates (N = 290). Results revealed good convergence between conceptually related personality traits.
