A test of two brief measures of the dark triad: the dirty dozen and short dark triad.

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. In general, scores from the SD3 scales manifested stronger convergent and incremental validity in relation to longer, more established measures of the DT constructs. Scores from both brief DT measures evidenced adequate discriminant validity as well as criterion validity in relation to traits from the five-factor model. However, the SD3 Narcissism Scale appears to assess primarily the grandiose aspects of this construct, whereas the DD captures both vulnerable and grandiose features of narcissism. Overall, if a short measure of the DT is required, the SD3 yields data that are more consistent with these constructs as they are measured using more established and validated measures.

Viewing the triarchic model of psychopathy through general personality and expert-based lenses.

The recently articulated and increasingly prominent triarchic model of psychopathy (TPM) posits the existence of 3 components of meanness, disinhibition, and boldness. In the current studies, 2 issues are addressed. First, although typically conceptualized in isolation from trait models of personality, the TPM components may be manifestations of basic personality dimensions. In Study 1 (N = 335), we test whether basic traits from the five-factor model (FFM) can account for the TPMs psychopathy domains. The FFM domains (Mean R2 = .65) and facets (Mean R2 = .75) accounted for substantial variance in the TPM domains, suggesting that the TPM can be viewed as being nested within a broader trait framework. Second, there is disagreement about which personality components are necessary and sufficient for psychopathy. In Study 2, we examine this issue using a between subject design in which expert raters (N = 46) were asked to view an FFM profile of the TPM domains and total score derived in Study 1 and rate the degree to which an individual with this profile would manifest symptoms of psychopathy, Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) personality disorders, and a variety of other psychiatric disorders. As expected, the profile associated with boldness was rated as less emblematic of psychopathy and related disorders (e.g., antisocial personality disorder; externalizing disorders) than the profiles for meanness or the total TPM score. These findings contribute to an ongoing debate addressing the degree to which domains like those articulated in the TPM are necessary or sufficient for the construct of psychopathy.

Identifying Essential Features of Juvenile Psychopathy in the Prediction of Later Antisocial Behavior: Is There an Additive, Synergistic, or Curvilinear Role for Fearless Dominance?

Despite years of research and the inclusion of psychopathy in DSM-5, there remains debate over the fundamental components of psychopathy. Although there is agreement about traits related to agreeableness and conscientiousness, there is less agreement about traits related to fearless dominance (FD) or boldness. The present article uses proxies of FD and self-centered impulsivity (SCI) to examine the contribution of FD-related traits to the predictive utility of psychopathy in a large, longitudinal sample of boys to test four possibilities: FD (a) assessed earlier is a risk factor, (b) interacts with other risk-related variables to predict later psychopathy, (c) interacts with SCI interact to predict outcomes, and (d) bears curvilinear relations to outcomes. SCI received excellent support as a measure of psychopathy in adolescence; however, FD was unrelated to criteria in all tests. It is suggested that FD be dropped from psychopathy and that future research focus on agreeableness and conscientiousness.

Examining the Relations Among the DSM–5 Alternative Model of Personality, the Five-Factor Model, and Externalizing and Internalizing Behavior.

Given long-standing criticisms of the DSM’s reliance on categorical models of psychopathology, including the poor reliability and validity of personality-disorder diagnoses, the American Psychiatric Association (APA) published an alternative model (AM) of personality disorders in Section III of the Diagnostic and Statistical Manual of Mental Disorders (DSM–5; APA, 2013), which, in part, comprises 5 pathological trait domains based on the 5-factor model (FFM). However, the empirical profiles and discriminant validity of the AM traits remain in question. We recruited a sample of undergraduates (N = 340) for the current study to compare the relations found between a measure of the DSM–5 AM traits (i.e., the Personality Inventory for DSM–5; PID-5; Krueger, Derringer, Markon, Watson, & Skodol, 2012) and a measure of the FFM (i.e., the International Personality Item Pool; IPIP; Goldberg, 1999) in relation to externalizing and internalizing symptoms. In general, the domains from the 2 measures were significantly related and demonstrated similar patterns of relations with these criteria, such that Antagonism/low Agreeableness and Disinhibition/low Conscientiousness were related to externalizing behaviors, whereas Negative Affectivity/Neuroticism was most significantly related to internalizing symptoms. However, the PID-5 demonstrated large interrelations among its domains and poorer discriminant validity than the IPIP. These results provide additional support that the conception of the trait model included in the DSM–5 AM is an extension of the FFM, but highlight some of the issues that arise due to the PID-5’s more limited discriminant validity.

Personality Disorder Traits: Perceptions of Likability, Impairment, and Ability to Change as Correlates and Moderators of Desired Level.

Historical conceptualizations have framed personality disorders (PDs) as unchanging and ego-syntonic. However, recent evidence suggests that individuals with PD traits may have some insight into their personality and consider those traits to be somewhat ego-dystonic. To replicate and extend previous findings, participants (N = 328) self-reported their PD trait levels, likability of those traits, impairment, capability for change, and desired trait levels. The results demonstrated that individuals with PD traits tolerate but still dislike those traits, believe that they cause them problems, and are interested in reducing them. Level of PD trait did not relate to perception of capability for change. Likability and impairment moderated most of the relations between actual PD trait and desired level. That is, there was a stronger correlation between actual and desired levels among individuals who liked the trait more; there was also greater agreement between actual and desired levels among individuals who found the traits less impairing. For 2 of the traits—Negative Affectivity and Detachment—individuals who felt more capable of changing these traits demonstrated greater agreement between their actual and desired levels. These data suggest that individuals with PD traits do not generally see them as particularly likable and see them as impairing; such impressions may have important implications for where individuals ultimately prefer to reside on these PD trait domains.

Personality disorder traits: Testing insight regarding presence of traits, impairment, and desire for change.

Mixed findings exist as to whether personality pathology involves a critical lack of awareness and insight. Research questions about insight and awareness in personality pathology are typically assessed via comparing self- and informant reports of traits. However, recent studies have measured insight by asking individuals to evaluate additional questions about impairment and desire to change. The present study uses a variety of approaches to examine these issues, including investigations of convergence between self- and informant reports (N = 197 dyads; correlations and comparisons of means) of personality psychopathology, desired trait levels, and perceptions of impairment. Convergence was observed between levels of self- and informant-reported traits, desired traits, and impairment. However, individuals rated themselves higher on pathological trait levels and impairment than did their informants. Furthermore, individuals with relatively higher pathological traits desired higher levels of these traits (but lower than their actual scores) than individuals with lower scores; on the actual measurement scale, however, these higher scorers rated their desired level below the neutral point. Overall, individuals with pathological personality traits possess a reasonable degree of insight into their actual trait levels and associated impairment.

Narcissism and Self-Esteem: A Nomological Network Analysis

Similarity between narcissism and self-esteem seems intuitive, as both capture positive perceptions of the self. In the current undertaking, we provide a broad comparison of the nomological networks of grandiose narcissism and explicit self-esteem. Pooling data from 11 existing samples (N = 4711), we compared the relations of narcissism and self-esteem to developmental experiences, individual differences, interpersonal functioning, and psychopathology. Both constructs are positively related to agentic traits and assertive interpersonal approaches, but differ in relation to agreeableness/communion. Self-esteem emerged as a wholly adaptive construct negatively associated with internalizing psychopathology and generally unrelated to externalizing behaviors. Unlike self-esteem, narcissism was related to callousness, grandiosity, entitlement, and demeaning attitudes towards others that likely partially explain narcissism’s links to maladaptive outcomes.

A Test of the Empirical Profile and Coherence of the DSM–5 Psychopathy Specifier.

The Diagnostic and Statistical Manual of Mental Disorders–5th edition (DSM–5; American Psychiatric Association, 2013) introduced a psychopathy specifier (DSM–5 PS) as part of the Section III diagnostic model of antisocial personality disorder. Designed to capture the construct of fearless dominance/boldness, the DSM–5 PS is assessed on the basis of the presence of low scores on traits of withdrawal and anxiousness, and high scores on attention seeking. These constructs have garnered attention in the past decade but are the subject of substantial debate as to their role in the conceptualization and assessment of psychopathy, given their limited relations to the maladaptive outcomes typically associated with this personality disorder. In the current study (N = 340 undergraduates; 170 informants), we examined the DSM–5 PS, both in composite form and its trait subscales, to investigate the degree to which the DSM–5 PS manifested empirical profiles associated with psychopathy and its maladaptive correlates. Consistent with prior fearless dominance/boldness research, the DSM–5 PS manifested limited relations with other components of psychopathy, symptoms of DSM–5 Section II and III antisocial personality disorder, and self- and informant-related impairment scores. When examined at the individual subscale level, the 3 DSM–5 PS subscales manifested only partially overlapping profiles and only 1 of the 3—Attention Seeking—demonstrated an association with maladaptivity (e.g., externalizing behaviors). These findings raise important concerns about the coherence and utility of the DSM–5 PS as a diagnostic specifier included in a psychiatric nosology.
