The term Dark Triad refers to three socially aversive personality dimensions (i.e., Machiavellianism, narcissism, and psychopathy) that are evident in the normal range of personality. Jones and Paulhus (2014) developed the Short Dark Triad (SD3) as a 27-item measure of the three constructs. To assess the psychometric properties of the Italian translation, 678 adult university students and 442 adolescent high school students were sampled. Cronbach's α values for the subscales were acceptable in both samples. Subscale intercorrelations ranged from.29 to.55 in adults and.29 to.53 in adolescents. Although subscale means were higher in the adolescent sample, the two item correlation matrices did not differ significantly. A confirmatory factor analysis using multidimensional full-information item response theory showed that a three-correlated-factor model provided the best fit in both adults and adolescents. When controlled for overlap, SD3 subscales showed adequate convergent and discriminant validity coefficients in both samples. The current research contributes to the literature on dark personalities in two ways: (a) It provides detailed psychometric support for the Italian translation of SD3 and (b) it directly compares SD3 performance in younger and older students.

Exploring Parent-Child Traits and Relationship Quality: A Network Study

Article

Jan 2024

Big five and dark triad personality traits are likely to influence the perceived quality of the parent-child relationship, as they can impact the behavior of family members and parenting styles. The main objective of this study was to analyze how adult children's and parents' personality traits affect the perceived quality of the parent-child relationship within dyadic interactions. The results revealed that parents' agreeableness and psychopathy had positive or negative effects on children's positive behaviors and feelings toward their parents, respectively. Moreover, mothers' and fathers' positive behaviors and feelings toward their children were positively or negatively associated, respectively, with children's conscientiousness and psychopathy. Furthermore, network analyses demonstrated that the impact of parents' emotional stability and psychopathy on children's perceived quality of the parent-child relationship varied depending on the gender of the parents. Thus, the relationship between personality traits and the perceived quality of the parent-child relationship is influenced by family roles, revealing a complex and variable structure in different dyadic family relationships.

AI can see you: Machiavellianism and Extraversion are reflected in eye-movements

Nov 2023

Introduction: Recent studies showed an association between personality traits and individual patterns of visual behaviour in laboratory and other settings. The current study extends previous research by measuring multiple personality traits in natural settings; and by comparing accuracy of prediction of multiple machine learning algorithms. Methods: Adolescent participants (N=35) completed personality questionnaires (Big Five Inventory and Short Dark Triad Questionnaire) and visited an interactive museum while their eye movements were recorded with head-mounted eye tracking. To predict personality traits the eye-movement data was analysed using eight machine-learning methods: Random forest, Adaboost, Naive Bayes, Support Vector Machine, Logistic Regression, k Nearest Neighbours, Decision Tree and a three-layer Perceptron. Results and Discussion: Extracted eye movement features introduced to machine learning algorithms predicted personality traits with above 33% chance accuracy (34%-48%). This result is comparable to previous ecologically valid studies, but lower than in laboratory-based research. Better prediction was achieved for Machiavellianism and Extraversion compared to other traits (10 and 9 predictions above the chance level by different algorithms from different parts of the recording). Conscientiousness, Narcissism and Psychopathy were not reliably predicted from eye movements. These differences in predictability across traits might be explained by differential activation of different traits in different situations, such as new vs. familiar, exciting vs. boring, and complex vs. simple settings. In turn, different machine learning approaches seem to be better at capturing specific gaze patterns (e.g. saccades), associated with specific traits evoked by the situation. Further research is needed to gain better insights into trait-situation-algorithm interactions.

The HEXACO Adjective Scales and Its Psychometric Properties

Article

Full-text available

Feb 2023

The HEXACO model divides the space of personality into six main dimensions: Honesty-Humility, Emotionality, eXtraversion, Agreeableness (vs. anger), Conscientiousness, and Openness to Experience. Despite the lexical foundation, no validated adjective-based instruments are available yet. This contribution describes the newly developed HEXACO Adjective Scales (HAS), a 60 adjectives instrument to measure the six main personality dimensions. Study 1 (N=368) proceeds to the first pruning of a large set of adjectives to identify potential markers. Study 2 (N=811) delineates the final list of 60 adjectives and provides benchmarks for the new scales' internal consistency, convergent/discriminant, and criterion validity. Study 3 (N=411) confirms the HAS factorial structure, internal consistency, and criterion validity. The study also provides evidence of temporal stability (test-retest reliability) and convergence between raters (peer/self-evaluation). The HAS shows excellent psychometric properties and constitutes a valuable tool for assessing the HEXACO personality dimensions using adjectives.

Development and Validation of the Need for Online Social Feedback (NfOSF) Scale

Article

Full-text available

Feb 2023

People are known to adjust their behavior based on social information. Starting from 2004, social media rapidly became a new social arena for human interaction, and scholars widely studied the effect of likes on people’s psyche and behavior. However, likes are just one of the possible social feedbacks among many others on social media. Moreover, social feedback influence should be analyzed recognizing individual differences in people’s needs and desires for them. This work was aimed at developing and validating (internally and externally) a scale able to capture people’s perceived need for online social feedback (NfOSF) applicable to most social media platforms. Data coming from 1403 Italian participants were used for this purpose. Exploratory and confirmatory factor analyses appeared to support a two-factor structure for the NfOSF scale, while Pearson’s correlation confirmed the expected positive relations of NfOSF factors with Narcissism, Need to Belong, FOMO, and Social media reputation perception. Eventually, NfOSF scale reliability appeared optimal.

The dark side of sexism in Argentina: Psychometric properties of the Short Dark Triad Personality measure and its relation with ambivalent sexism

Article

Full-text available

Nov 2022

One of the main evaluation instruments of the dark side of personality has been the Short Dark Triad of Personality (SD3), that includes Machiavellianism, Narcissism and Psychopathy traits. Although other adaptations of this scale have been made in several countries, its psychometric properties have never been tested in Argentina. Different studies addressed that dark triad scores are related to different expressions of sexist prejudice. One of the issues that have been traditionally considered to understand intimate, yet unequal relationships between men and women, is prejudice toward women. Ambivalent sexism combines two types of sexist attitudes: hostile, and benevolent sexism. While hostile sexism involves attitudes of outright intolerance towards women, benevolent sexism is defined as a set of attitudes that comprises the perception of women in a positive emotional tone. The aim of the study was to analyze the Dark Triad of Personality scale in the Argentinian context and its relationships whit ambivalent sexism. A total of 1,198 individuals residing in different regions of Argentina participated, from different genders (woman = 59.5%), from 18 to 75 years old (M = 45.17 SD = 15.08). Main results indicated adequate psychometric properties for the Short Dark Triad of Personality scale in the Argentinian context. In addition, the three traits of the dark triad were significantly related to hostile and benevolent sexism, which indicate that one of the variables to keep addressing in order to comprise and eventually reduce prejudice towards women would be the dark triad of personality. Main results are discussed, in order to strengthen the understanding of the relationships between the dark triad and ambivalent sexism.

The Dark Triad is dead, long live the Dark Triad: An item-response theoretical examination of the Short Dark Tetrad

Article

Dec 2022
PERS INDIV DIFFER

Research on the Dark Tetrad (Machiavellianism, narcissism, psychopathy, and sadism) is burgeoning. Therefore, psychometrically sound measures are required to ensure that predictions based on these constructs are reliable and valid. A recently devised scale to assess all traits simultaneously is the Short Dark Tetrad (SD4; Paulhus et al., 2021). Previous studies demonstrated the general suitability of the SD4 in terms of classical test theory, but item response theoretical (IRT) analyses are still missing, whereby IRT approaches extract more information on the items and scales and tests assumptions untested in classical test theory. Thus, we evaluated the subscales of the SD4 using IRT modeling (N = 594). Unlike the sadism subscale, the Machiavellianism, narcissism, and psy-chopathy subscales had satisfactory fit of the two-parameter polytomous IRT models and provided ample information across the respective trait continua. The sadism subscale, however, exhibited problems related to item discrimination (i.e., in differentiating between individuals with similar levels) and item (category transition) difficulties (i.e., quantifying how "difficult" it is to endorse higher compared to next lower response categories). The results thus emphasize the need for a thorough revision of the items of the sadism scale.

Humor and the dark triad: Relationships among narcissism, Machiavellianism, psychopathy and comic styles

Article

Oct 2022
PERS INDIV DIFFER

The present study investigated the relationships between the eight comic style markers and the dark triad traits of personality. A sample of 715 adults (188 men and 527 women aged 19 to 83 years; M = 42.40; SD = 12.74) completed two questionnaires: the Comic Style Markers (CSM) and the Short Dark Triad (SD3). All the darker styles were related to the three facets of the dark triad. Narcissism was mainly related to the lighter styles and was the best predictor of wit. Conversely, the darker styles were best predicted by psychopathy and Machiavellianism, especially irony, sarcasm, and cynicism.

Introducing the Shorter Dark Tetrad for Muslim Societies (SD4-MS): a study among young adults in Pakistan

Mar 2022

Abstract This paper examines the psychometric properties of the Short Dark Tetrad, presented for online administration, among a sample of 370 young adults between the ages of 18 and 26 who were born in the Punjab and who had lived there since their birth. With the omission of one item from each of the four scales (Machiavellianism, psychopathy, narcissism, and sadism) the clear four factor structure was recovered with cross-loadings remaining on four items. All four scales recorded acceptable or good levels of internal consistency reliability (alpha). This Shorter Dark Tetrad (SD4-MS) is commended for further use within predominantly Muslim societies.

Comparing the Measured and Latent Dark Triad: Are Three Measures Better than One?

Article

Full-text available

Oct 2011

Could measurement level be a factor worth considering when studying the Dark Triad (i.e., narcissism, psychopathy, and Machiavellianism)? In two studies (N = 465), we compared the relative fit of two Dark Triad models: one that treats the three measures as separate-yet-related personality traits and another that treats the measures as tapping a single, latent construct. Mid-level personality traits, such as mate-retention strategies (Study 1) were best explained by a three-measure model, whereas the higher-order trait of sociosexuality (Study 2), were best explained by a single, latent-factor model. When considering mid-level measurement in personality, the three traits may provide independent effects for interpersonal relationships, whereas at the higher-order level, the three traits may function as a single entity relating to other higher-order traits. We suggest one should consider level of measurement between the predictor and criterion variables to better predict correlations among variables such as the Dark Triad.

Controversies in Narcissism

Mar 2017
ANNU REV CLIN PSYCHO

There has been a surge in interest in and research on narcissism and narcissistic personality disorder (NPD). Despite or because of this increased attention, there are several areas of substantial debate that surround the construct, including descriptions of grandiose and vulnerable dimensions or variants, questions regarding the existence of a consensual description, central versus peripheral features of narcissism, distinctions between normal and pathological narcissism, possible etiological factors, the role of self-esteem narcissism, where narcissism should be studied, how it can be assessed, and its representation in diagnostic nosologies. We suggest that a failure to distinguish between grandiose (i.e., overtly immodest, self-centered, entitled, domineering) and vulnerable (e.g., self-centered, distrustful, neurotic, introverted) presentations of narcissism has led to a less cohesive and coherent literature and that trait-based models of personality and personality disorder can bring greater clarity to many of these important debates. Expected final online publication date for the Annual Review of Clinical Psychology Volume 13 is May 7, 2017. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Duplicity Among the Dark Triad: Three Faces of Deceit

Article

Full-text available

Mar 2017

Although all 3 of the Dark Triad members are predisposed to engage in exploitative interpersonal behavior, their motivations and tactics vary. Here we explore their distinctive dynamics with 5 behavioral studies of dishonesty (total N = 1,750). All 3 traits predicted cheating on a coin-flipping task when there was little risk of being caught (Study 1). Only psychopathy predicted cheating when punishment was a serious risk (Study 2). Machiavellian individuals also cheated under high risk—but only if they were ego-depleted (Study 3). Both psychopathy and Machiavellianism predicted cheating when it required an intentional lie (Study 4). Finally, those high in narcissism showed the highest levels of self-deceptive bias (Study 5). In sum, duplicitous behavior is far from uniform across the Dark Triad members. The frequency and nature of their dishonesty is moderated by 3 contextual factors: level of risk, ego depletion, and target of deception. This evidence for distinctive forms of duplicity helps clarify differences among the Dark Triad members as well as illuminating different shades of dishonesty.

Is Boldness Relevant to Psychopathic Personality? Meta-Analytic Relations With Non-Psychopathy Checklist-Based Measures of Psychopathy

Article

Full-text available

Nov 2015

Two recent meta-analyses have suggested that boldness, as assessed by the Psychopathic Personality Inventory (PPI) Fearless Dominance dimension, is largely unrelated to total or factor scores on the Psychopathy Checklist-Revised (PCL-R), raising questions concerning the relevance of largely adaptive features to psychopathy. Nevertheless, given that the PCL was developed and validated among prisoners, it may place less emphasis than do other psychopathy measures on adaptive traits, such as fearlessness, social poise, and emotional resilience. We conducted a meta-analysis (N = 10,693) of the relations between (a) boldness, as assessed by the PPI and its derivatives or measures of the triarchic model of psychopathy, and (b) non-PCL-based psychopathy measures across 32 samples. The average weighted correlation between boldness and psychopathy was medium to large (r = .39) and considerably higher than reported in prior meta-analyses; when analyses were restricted to well-validated psychopathy measures, the correlation rose to r = .44. We did not find support for the position that boldness is significantly less related to psychopathy than are the other 2 dimensions of the triarchic model. Our findings strongly suggest that boldness is relevant to at least some well-validated measures of psychopathy, and raise further questions regarding the boundaries of this condition.

Psychopathy and Deviant Workplace Behavior: A Comparison of Two Psychopathy Models

Article

Jun 2017
J PERS DISORD

Although psychopathy is an interpersonally harmful construct, few studies have compared different psychopathy models in predicting different types of workplace deviance. We examined how the Triarchic Psychopathy Model (TRI-PM) and the Self-Report Psychopathy-Short Form (SRP-SF) predicted deviant workplace behaviors in two forms: sexual harassment and deviant work behaviors. Using structural equations modeling, the latent factor of psychopathy was predictive for both types of deviant workplace behavior. Specifically, the SRP-SF significantly predicted both measures of deviant workplace behavior. With respect to the TRI-PM, meanness and disinhibition significantly predicted higher scores of workplace deviance and workplace sexual harassment measures. Future research needs to investigate the influence of psychopathy on deviant workplace behaviors, and consider the measures they use when they investigate these constructs.

Assessing Dimensions of Pathological Narcissism: Psychometric Properties of the Short Form of the Five-Factor Narcissism Inventory in a Sample of Italian University Students

Article

May 2017

To evaluate the psychometric properties of the Italian translation of the Five-Factor Narcissism Inventory–Short Form (FFNI–SF), 1,063 Italian university students were administered the scale, along with the Pathological Narcissism Inventory (PNI) and the Measure of Disordered Personality Functioning (MDPF). In general, the FFNI–SF scales showed good internal consistency (median α = .76; median interitem r = .44) and structural analyses suggested a 3-component model of FFNI–SF scales that was similar to that reported by Sherman et al. (2015). FFNI–SF second-order scales yielded meaningful convergent and discriminant correlations with PNI second-order grandiose and vulnerable dimensions. Finally, FFNI–SF second-order scales correlated in expected ways with 2 dimensions of personality dysfunction.

Is Hillary dishonest and Donald narcissistic? A HEXACO analysis of the presidential candidates' public personas

Article

Nov 2016
PERS INDIV DIFFER

The 2016 American election campaign has seen an exceptionally negative view of both candidates (Clinton/ Trump), and what seems like passionate support for one side or the other. Approval and honesty ratings of b 50% throughout the campaign suggest that neither candidate is viewed positively. In a campaign that is increasingly focused on temperament and personality, we examined the public personalities of the two candidates. Ten HEXACO personality experts completed HEXACO-PI-R observer reports for Hillary Clinton and Donald Trump based on public personas. Scores were transformed into percentiles based on normed values for HEXACO observer reports. Clinton was rated as low on H, E, and Altruism, normal on X and A, and high on C and O. Trump, on the other hand, was rated as exceptionally low on H, A, and Altruism, very low on E, low on C and O, and high on X. Facet level scores clarify the specific traits lowering or raising the candidates' scores. Previous research has shown that narcissism, psychopathy, and Machiavellianism (the Dark Triad) were associated with lower Honesty-Humility , Emotionality, Agreeableness, and Conscientiousness. Clinton scores low on the first two of these, while Trump scores very low to exceptionally low on all four traits.

Differentiating Dark Triad Traits Within and Across Interpersonal Circumplex Surfaces

Article

Apr 2016
ASSESSMENT

Recent discussions surrounding the Dark Triad (narcissism, psychopathy, and Machiavellianism) have centered on areas of distinctiveness and overlap. Given that interpersonal dysfunction is a core feature of Dark Triad traits, the current study uses self-report data from 562 undergraduate students to examine the interpersonal characteristics associated with narcissism, psychopathy, and Machiavellianism on four interpersonal circumplex (IPC) surfaces. The distinctiveness of these characteristics was examined using a novel bootstrapping methodology for computing confidence intervals around circumplex structural summary method parameters. Results suggest that Dark Triad traits exhibit distinct structural summary method parameters with narcissism characterized by high dominance, psychopathy characterized by a blend of high dominance and low affiliation, and Machiavellianism characterized by low affiliation on the problems, values, and efficacies IPC surfaces. Additionally, there was some heterogeneity in findings for different measures of psychopathy. Gender differences in structural summary parameters were examined, finding similar parameter values despite mean-level differences in Dark Triad traits. Finally, interpersonal information was integrated across different IPC surfaces to create profiles associated with each Dark Triad trait and to provide a more in-depth portrait of associated interpersonal dynamics.

Item response theory and the measurement of psychiatric constructs: Some empirical and conceptual issues and challenges

Article

Apr 2016

Item response theory (IRT) measurement models are now commonly used in educational, psychological, and health-outcomes measurement, but their impact in the evaluation of measures of psychiatric constructs remains limited. Herein we present two, somewhat contradictory, theses. The first is that, when skillfully applied, IRT has much to offer psychiatric measurement in terms of scale development, psychometric analysis, and scoring. The second argument, however, is that psychiatric measurement presents some unique challenges to the application of IRT – challenges that may not be easily addressed by application of conventional IRT models and methods. These challenges include, but are not limited to, the modeling of conceptually narrow constructs and their associated limited item pools, and unipolar constructs where the expected latent trait distribution is highly skewed.

The triarchic psychopathy measure (TriPM): Alternative to the PCL-R?

Article

Mar 2016
AGGRESS VIOLENT BEH

Psychopathic personality disorder is the subject of many research papers and in particular in the context of forensic settings, where its link to risk of future violent has been established. This topic is well examined but there is still considerable debate bout the nature of the construct and how psychopathy is measured. Contemporary models such as the triarchic theory (Patrick, Fowles, and Krueger (2009) have been put forward yet the research into psychopathy tends to rely on one assessment tool, the Psychopathy Checklist-Revised (PCL-R; Hare, 2003) that is argued not to capture elements of psychopathy such as boldness. The Triarchic Psychopathy Measure (TriPM; Patrick, 2010) is a measure that is based on the triarchic theory, and it places an equal focus on boldness when measuring psychopathy. It is however a self-report instrument, and this approach has many limitations. This paper aims to review the scientific support for the TriPM and to discuss its potential application to clinical practice. It concludes that the TriPM may not yet be a contender for the PCL-R throne as the sole tool of choice for psychopathy measurement, but the research into the application of the TriPM is expanding our understanding of psychopathy as a construct.
