Mutually attracted or repulsed? Actor–partner interdependence models of Dark Triad traits and relationship outcomes

Although the Dark Triad traits – narcissism, Machiavellianism, and psychopathy – have been studied in individuals, little is known about their roles in dating relationships. Forty-five heterosexual undergraduate couples (N = 90) reported measures of the Dark Triad and relationship commitment and satisfaction. Within couples, assortative mating was slightly negative for narcissism, marginally positive for Machiavellianism, and significantly positive for psychopathy. Using actor–partner interdependence models, we explored the extent to which satisfaction mediated the direct associations between the Dark Triad and commitment. Men’s satisfaction marginally mediated the women’s Dark Triad → men’s commitment negative association. Among the three Dark Triad subscales, satisfaction marginally mediated both of the actor-effect-based psychopathy → commitment negative associations. We discuss possible implications for couples’ relationship strategies.     

Dorian Gray without his portrait: Psychological,social, and physical health costs associated with the Dark Triad

We examined how the Dark Triad (i.e., narcissism, psychopathy, and Machiavellianism) traits—as different social strategies—were associated with various health outcomes. In samples of American undergraduates (N = 1389), Australian high school students (N = 2023), and British undergraduates (N = 280), we examined the physical, social, and psychological costs associated with the Dark Triad traits. Narcissism was linked to few mental and physical ailments, suggesting it may provide a social buffer from negative health outcomes (Studies 1 and 2). Psychopathy (Studies 1 and 2) and Machiavellianism (Study 2) were linked to a number of psychological and physical health conditions. In addition, psychopathy was related to diminished life expectancy, whereas narcissism was related to enhanced life expectancy (Study 3). Our findings provide evidence that each of these personality traits is linked to various psychosocial tradeoffs and different methods of coping with stress and adaptive problems.     

Competition,autonomy, and prestige: Mechanisms through which the Dark Triad predict job satisfaction

Organizational researchers increasingly recognize the need to consider the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) when explaining undesirable work outcomes (e.g., counterproductive behaviors). However, little research has focused on the motivations of those who actually hold the traits. In this study (N = 361) we examined how the Dark Triad traits predispose individuals to perceive situations as competitive, prestigious, and comprised of restrictions (i.e., autonomy) which differentially predict job satisfaction. Individuals high on psychopathy and Machiavellianism perceived their workplaces as competitive, whereas individuals high on narcissism perceived their workplaces as prestigious and with fewer restrictions. Sex differences in perceptions were fully mediated by psychopathy and Machiavellianism. We discuss our results from an Evolutionary Industrial/Organization Psychology framework.     

The targets of all treachery: Delusional ideation,paranoia, and the need for uniqueness as mediators between two forms of narcissism and conspiracy beliefs

The present cross-sectional study (N_Participants = 397; N_Informants = 460) examined the association of both grandiose narcissism and vulnerable narcissism with conspiracy beliefs in the context of four theoretically-relevant mediators. Participants who were higher in grandiose narcissism and vulnerable narcissism were more likely to believe in conspiracy theories, seemingly because they were more likely to hold unusual beliefs. There was, likewise, some evidence to suggest that those high in vulnerable narcissism believe in conspiracy theories because they suffer from paranoia, whereas those high in grandiose narcissism believe in conspiracy theories because of a desire to be unique. Together, these results suggest that the conspiracist ideation seen among those high in grandiose narcissism and vulnerable narcissism is a consequence of features that are shared between and unique to each of the traits.     

Adolescent narcissism and its association with different indices of prosocial behavior

This study sought to replicate previous findings that adolescent pathological narcissism is linked to self-reported prosocial behavior (Kauten & Barry, 2014) and further investigated the relation of self-reported narcissism with self-, parent- and peer-reported prosocial behavior, as well as prosocial intentions, in 155 at-risk adolescents (M age = 16.8 years, SD = .77; 127 males, 28 females). Non-pathological narcissism demonstrated a positive relation with parent-reported prosocial behavior, and grandiose narcissism was positively related to both self- and parent-reported prosocial behavior. Vulnerable narcissism did not demonstrate a significant relation with any variant of prosocial behavior. Thus, the relation between adolescent narcissism and prosocial behavior appears to vary based on the dimension of narcissism and the method of assessing prosocial behavior.     

The young and the restless: Examining the relationships between age,emerging adulthood variables,and the Dark Triad

The Dark Triad is a set of correlated personality variables (i.e., narcissism, psychopathy, and Machiavellianism) that are related to myriad behaviors. Myriad studies have been conducted to test the relations between the Dark Triad and other personality variables (e.g., the Big 5); however, the developmental correlates have been understudied. In the current study, we examined how markers of emerging adulthood and age predict the Dark Triad traits using a cross-sectional design. Participants (N = 442) of varying ages (M age = 32.99, range = 18–74) completed Dark Triad measures and a validated questionnaire used to assess the degree to which participants believe they have successfully navigated through various facets of emerging adulthood. Emerging adulthood facets (e.g., negativity, other-focused, and feeling in-between) correlated with several Dark Triad traits. Additionally, several emerging adulthood facets mediated the relation between age and the Dark Triad traits; i.e., older participants were lower on the Dark Triad traits because of the successful transition through emerging adulthood. Results are discussed in terms of the Theory of Emerging Adulthood (Arnett, 2000).     

Hedonism,Achievement, and Power: Universal values that characterize the Dark Triad

Using a sample of Swedes and Americans (N = 385), we attempted to understand the Dark Triad traits (i.e., Machiavellianism, narcissism, and psychopathy) in terms of universal social values. The Dark Triad traits correlated significantly with all 10 value types, forming a sinusoid pattern corresponding to the value model circumplex. In regression analyses, Machiavellianism and narcissism were positively associated with the values Achievement and Power, while psychopathy was positively associated with the values Hedonism, and Power. In addition, the Dark Triad traits explained significant variance over the Big Five traits in accounting for individual differences in social values. Differences between the Swedish and the US sample in the social value Achievement was mediated by the Dark Triad traits, as well as age. Given the unique complex of values accounted for by the Dark Triad traits compared to the Big Five traits, we argue that the former account for a system of self-enhancing “dark values”, often hidden but constantly contributing in evaluations of others.     

Fearing,not loving,the reflection: Narcissism,self-esteem,and self-discrepancy theory

This study used self-discrepancy theory to explore self-esteem and narcissism. College students (N = 450) completed measures of self-discrepancy, affect, self-esteem, and narcissism. Hierarchical multiple regression analyses found that self-discrepancies explained variance in self-esteem and narcissism beyond that explained by affect. Results also indicated that the actual-ideal and actual-undesired self-discrepancies predicted self-esteem, while the actual-undesired self-discrepancy was the only significant predictor of narcissism. This study provides evidence of incremental validity for self-discrepancies in measuring self-esteem and narcissism. It also suggests that narcissism is associated with an undesired, not an ideal, self-concept.     

Valuing myself over others: The Dark Triad traits and moral and social values

In samples from America and Germany (N = 1353), we examined how the Dark Triad traits related to different value systems as measured by Moral Foundations and Social Values. Psychopathy was linked to diminished concerns for all Moral Foundations, Machiavellianism was linked to a moral flexibility, and narcissism was linked to a socially desirable form of morality. Machiavellianism and psychopathy scores were associated with a devaluing of collective interests, whereas narcissism was associated with a valuing of individual interests through the value of Self-Enhancement. Individual differences in a variety of values mediated part of the sex differences in the Dark Triad traits. We contend that what makes the Dark Triad traits unique and interesting is that they share a unique complex of values that might run counter to societal expectations for selflessness.     

When are grandiose and vulnerable narcissists least helpful?

Grandiosity and vulnerability are distinct dimensions of narcissism, but little research has examined their differences regarding prosocial behavior. This investigation is the first to test the hypotheses that grandiose narcissism predicts withholding help under high social pressure, whereas vulnerable narcissism predicts withholding help under low social pressure. Undergraduate participants (N = 220, M_age = 19.5, 142 women) were partnered with a confederate for the supposed purpose of a mock counseling session. The confederate ruined the session by demonstrating inconsiderate behavior, after which the participant encountered two opportunities to help the confederate: one presented under high social pressure to help, the other presented under low social pressure to help. Measures also assessed participants’ prosocial emotions, including empathy for and forgiveness of the confederate. Consistent with hypotheses, grandiose narcissism predicted less helping under high social pressure, whereas vulnerable narcissism predicted less helping under low social pressure, the latter relationship being mediated by reduced forgiveness. Vulnerable narcissism was also associated with less empathy and forgiveness. Grandiose and vulnerable narcissism differentially predicted helping behavior depending on the amount of social pressure to help. These results conform to theoretical distinctions between grandiosity and vulnerability regarding social dominance and internalization.     

Where birds flock to get together: The who,what, where,and why of mate searching

An understudied area of personality psychology is how personality traits might facilitate structuring of one’s environment toward goals like mating. In four studies (N = 1325), we examined (1) self-reports of where individuals go to find long-term and short-term mates, (2) how personality traits are associated with the use of these locations, and (3) how the sexes differ in their selection of mate search locations. Men were more likely than women were to use short-term (e.g., bars) than long-term (e.g., community events) niches, but did not differ in success in those niches and agreed on the nature of those niches. Slow life history traits, conscientiousness and agreeableness, were linked to preferences for long-term niches whereas, fast life history traits, narcissism and dishonesty, were linked to preferences for short-term mating niches.     

Narcissism and lack of interpersonal forgiveness: The mediating role of state anger,state rumination,and state empathy

The present study investigated the unique contributions of two distinct dimensions of narcissism – admiration and rivalry – to two facets of unforgiveness: revenge and avoidance. In addition, we examined whether state anger, state rumination, and state empathy mediate this relationship. Using a large sample (N = 1040), we found that admiration was negatively related to revenge and avoidance via higher empathy for the transgressor. By contrast, rivalry was positively related to revenge and avoidance via greater anger and rumination and less empathy. Findings suggest that the mechanisms through which narcissism and lack of forgiveness are associated are better understood if we disentangle admiration and rivalry and consider both cognitive and affective antecedents of narcissists’ unforgiving motivations.     

Signature size signals sociable dominance and narcissism

Handwritten signatures have been traditionally associated with personality traits. In this study, we examined the relationship of signature size with intrasexual competition, aggressive and sociable dominance, narcissism, and self-esteem in a sample of Uruguayan university students (N = 340). The study went methodologically beyond current research by examining three different operationalizations of signature size, and by controlling for potential confounders: number of characters in the printed name, average character area in the printed name—a proxy for overall writing size—, and signature style. After controlling for these potential confounders and demographic variables, our results showed a significant link between signature size and sociable dominance, both for males and females, while narcissism was only in females significantly associated with signature size.     

Pathology,pseudopathology, and the Dark Triad of personality

The Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) have traditionally been viewed as undesirable and pathological. In contrast, an evolutionary perspective suggests that traits like these might be pseudopathologies; traits that society actively dislikes in that they pose a threat to the collective good. We examined (N = 290) how the Dark Triad traits related to intrapersonal (i.e., behavioral dysfunction), quasibehavioral (i.e., reactive and proactive aggression), and interpersonal (i.e., communal and exchange orientation) factors. Psychopathy predicted high rates of behavioral dysregulation and both forms of aggression. Psychopathy and Machiavellianism showed an aversion towards communalism but an exchange orientation to social relationships. Lastly, individual differences in the Dark Triad traits accounted for part (5–22%) of the sex differences in social strategies and aggression. The theoretical implications of these findings are discussed in, and in support of, an evolutionary paradigm.     

Feeling me,feeling you? Links between the Dark Triad and internal body awareness

Despite a rapid increase of interest in the Dark Triad of personality (i.e., psychopathy, narcissism and Machiavellianism), very little research has focused on links between the Dark Triad and internal body awareness (i.e., interoception). In an on-line study (N = 323), we investigated the relationship between the Dark Triad and different facets of interoception, such as awareness and trust in body sensations, the capacity to regulate attention, and an awareness of mind–body integration. When we controlled for shared variance between the Dark Triad traits, narcissism emerged as a positive predictor for all but one facet of interoception. Primary psychopathy was a positive predictor of attention regulation, whereas secondary psychopathy was a negative predictor of awareness of body sensation and attention regulation. Machiavellianism emerged as a negative predictor of trusting body sensations. The findings are discussed within an evolutionary framework.     

The mediating role of self-esteem in the relationship between big five personality traits and depressive symptoms among Chinese undergraduate medical students

The objectives of this study were to examine the correlations between big five personality traits and depressive symptoms among Chinese undergraduate medical students, and to explore the mediating role of self-esteem on the correlations. Self-reported questionnaires, including Big Five Inventory, the Center for Epidemiologic Studies Depression Scale, Rosenberg’s Self-Esteem scale, and socio-demographic section were distributed to 2000 undergraduate medical students at four medical colleges and universities in Liaoning province, China, in June 2014. 1738 students became the final subjects. After adjustment for age and gender, agreeableness (β = −0.329) and openness (β = −0.096) were negatively related to depressive symptoms, while neuroticism (β = 0.245) was positively related to the symptoms. Self-esteem functioned as a mediator in the relationship between agreeableness (a * b = −0.154, 95% CI: −0.182, −0.127)/openness (a * b = −0.097, 95% CI: −0.124, −0.069)/neuroticism (a * b = 0.031, 95% CI: 0.007, 0.058) and depressive symptoms. Therefore, identifying at-risk students and undertaking appropriate intervention strategies that focus on both personality traits and self-esteem may be effective in preventing and reducing depressive symptoms among Chinese medical students.     

Body image and personality among British men: Associations between the Big Five personality domains,drive for muscularity,and body appreciation

The present study examined associations between the Big Five personality domains and measures of men's body image. A total of 509 men from the community in London, UK, completed measures of drive for muscularity, body appreciation, the Big Five domains, and subjective social status, and provided their demographic details. The results of a hierarchical regression showed that, once the effects of participant body mass index (BMI) and subjective social status had been accounted for, men's drive for muscularity was significantly predicted by Neuroticism (β = .29). In addition, taking into account the effects of BMI and subjective social status, men's body appreciation was significantly predicted by Neuroticism (β = −.35) and Extraversion (β = .12). These findings highlight potential avenues for the development of intervention approaches based on the relationship between the Big Five personality traits and body image.     

Narcissistic self-esteem or optimal self-esteem? A Latent Profile Analysis of self-esteem and psychological entitlement

Research into the relationship between self-esteem and narcissism has produced conflicting results, potentially caused by hidden subpopulations that exhibit distinct positive or negative associations. This research uses Latent Profile Analysis to identify profiles within a national panel study (N = 6471) with differing relationships between psychological entitlement and self-esteem. We identified a narcissistic self-esteem profile (9%) characterised by high entitlement and high self-esteem, an optimal self-esteem (38.4%) profile characterised by high self-esteem but low entitlement, and three profiles that reported low entitlement but different levels of self-esteem. We additionally predicted profile membership using Big-Five traits. Results indicate that self-esteem is a necessary but not sufficient condition for high entitlement, and entitlement is not highly prevalent in New Zealand.     

Sense of direction: General factor saturation and associations with the Big-Five traits

The ability to locate and orient ourselves with respect to environmental space is known as sense of direction (“SOD”). While there is considerable evidence for the predictive utility of self-report measures of this psychological construct, relatively little research has investigated the psychometric properties of the self-report scale by which it is most commonly measured – the Santa Barbara Sense of Direction scale (SBSOD, Hegarty et al., 2002) – or the broader personality correlates. The present study evaluated the factor structure of the SBSOD following administration to 12,155 individuals and situated it among prominent sources of individual differences, specifically the Big Five personality traits and intelligence. Findings suggest that the SBSOD scale has relatively high general factor saturation, and that a considerable portion of the variance in SBSOD scores is explained by other personality traits, including Conscientiousness (r = 0.33), Intellect (r = 0.27), Emotional Stability (r = 0.26), and Extraversion (r = 0.23). Cognitive ability was less highly correlated with SBSOD scores when measured at the level of general intelligence (r = 0.11) and in terms of mental rotation ability (r = .07). Recommendations are given for revision of the SBSOD scale based on item-level analyses.     

The relationship between hip,knee and ankle muscle mechanical characteristics and gait transition speed

The purpose of the present study was to explore the relationship between mechanical characteristics of hip, knee and ankle extensor and flexor muscle groups and gait transition speed. The sample included 29 physically active male adults homogenized regarding their anthropometric dimensions. Isokinetic and isometric leg muscle mechanical characteristics were assessed by an isokinetic dynamometer, while individual walk-to-run (WRT) and run-to-walk transition speeds (RWT) were determined using the standard increment protocol. The relationship between transition speeds and mechanical variables scaled to body size was determined using Pearson correlation and stepwise linear regression. The highest correlations were found for isokinetic power of ankle dorsal flexors and WRT (r = .468, p < .01) and the power of hip extensors and RWT (r = .442, p < .05). These variables were also the best predictors of WRT and RWT revealing approximately 20% of explained variance. Under the isometric conditions, the maximal force and rate of force development of hip flexors and ankle plantar flexors were moderately related with WRT and RWT (ranged from r = .340 to .427). The only knee muscle mechanical variable that correlated with WRT was low velocity knee flexor torque (r = .366, p < .05). The results generally suggest that the muscle mechanical properties, such as the power of ankle dorsal flexors and hip extensors, influence values of WRT and RWT.
