Background and Objectives: The primary purpose of the article was to examine the relationship between dark and light personality traits in university students enrolled in the Faculty of Sport Sciences. Materials and Methods: Data were collected from 518 students (208 female, 310 male) with an average age of 20.89 (±2.25). The Short Dark Triad and the Light Triad Scales were used. Harman\'s single-factor analysis minimized measurement error, and various statistical methods assessed the effect of gender and age on personality traits. Results: Results indicated a positive correlation among dark personality traits, while light personality traits exhibited more complex relationships. Gender and age were found to significantly influence certain personality traits. Conclusions: This study contributes to the sports literature by exploring the role of demographic variables in personality formation.

UNASSIGNED: This meta-analysis investigates the relationships between the Dark Triad personality traits (narcissism, Machiavellianism, and psychopathy) and mental toughness. Previous research has shown mixed results regarding the influence of these traits on mental toughness. The objective of this meta-analysis is to synthesize existing literature and provide a comprehensive understanding of how Dark Triad traits correlate with mental toughness.
UNASSIGNED: A comprehensive literature search was conducted in 7 databases, Data were extracted by correlation and analyzed using a random-effects model.
UNASSIGNED: The results yielding 27 effect sizes with a total of 12,378 participants, revealed a significant moderate positive association between narcissism and mental toughness (r = 0.327, p < 0.001), suggesting that individuals with higher levels of narcissism tend to exhibit greater mental toughness. However, no significant associations were found between Machiavellianism (r = 0.023, p = 0.719) or psychopathy (r = -0.022, p = 0.625) and mental toughness.
UNASSIGNED: The findings contribute to a more nuanced understanding of the Dark Triad traits and their differential associations with adaptive psychological constructs, highlighting the unique role of narcissism in mental toughness. This meta-analysis provides valuable insights for future research and practical applications in fostering adaptive aspects of narcissism while mitigating its potential maladaptive consequences.

UNASSIGNED: While schadenfreude is commonly experienced in interpersonal relationships, it is generally considered immoral. Although previous research has explored the factors relating to schadenfreude, including certain personality traits, moral disengagement, and humor styles, our understanding of these factors remains limited. The present study examined the mediating effects of moral disengagement and aggressive humor style in the relationship between the Dark Triad traits and schadenfreude.
UNASSIGNED: In this study, a sample of 693 Iranian students (69.4% female), was recruited using a convenient sampling method, consisting of 330 undergraduate, 230 graduate, and 133 Ph.D. students. The trait schadenfreude scale, the short Dark Triad, the moral disengagement scale, and the aggressive humor style scale were measured through an online survey.
UNASSIGNED: The study found that Machiavellianism, narcissism, and psychopathy were positively related to schadenfreude, aggressive humor style, and moral disengagement. Additionally, aggressive humor style and moral disengagement mediated the relationship between Machiavellianism, narcissism, and psychopathy with schadenfreude.
UNASSIGNED: This study provides insights into the complex relationships between Dark Triad traits, moral disengagement, aggressive humor style, and schadenfreude. The findings suggest that individuals with higher levels of Dark Triad traits may be more likely to experience pleasure from others\' misfortunes. Furthermore, the study highlights the importance of moral disengagement and aggressive humor style as potential mechanisms underlying the relationship between Dark Triad traits and schadenfreude. Further research should be done to explore the motivational factors influencing schadenfreude in specific settings, thereby elucidating these connections.

UNASSIGNED: A good physician should be empathic and altruistic, among other qualities. Therefore, the levels of socially undesirable personality traits (Dark Triad) as well as implicit motives of achievement, affiliation and power (Multi-Motive Grid) among medical students as future physicians were analyzed at two different points in their medical training.
UNASSIGNED: This study includes 380 medical students in their first year and 217 in their third year in Germany. All participants completed the Dirty Dozen (DD) and Multi-Motive Grid (MMG) questionnaires at the end of two different classes as paper-and-pencil tests. Relevant differences of the Dark Triad traits between the medical students and reference sample and the two different cohorts, as well as their implicit motives, the associations of Dark Triad traits and MMG components and gender differences of the Dark Triad traits were calculated.
UNASSIGNED: There were no significant group differences between year one and year three medical students in narcissism, psychopathy and Machiavellianism (Dark Triad). There were no significant differences between the medical students and reference sample except in psychopathy. Male students scored significantly higher in the Dark Triad traits than female students. In the MMG, first-year students scored significantly higher levels in Fear of Rejection, and lower levels in Hope of Success and Hope of Power than the third-year students. Some associations were found between narcissism and Machiavelliansim with Hope of Success, Hope of Power and Fear of power.
UNASSIGNED: Dark Triad traits already appear to exist before the commencement of medical studies. These traits do not differ significantly between the medical students and reference sample; only a few MMG components seem to differ at different stages of their studies. This lack of differences between the medical students and validation cohort indicates that tests based on (undesirable) personality traits are not suitable criteria for the admission selection of medical students.

(1) Background: The dark triad refers to a personality configuration mainly characterized by the presence of Machiavellianism, narcissism, and psychopathy. Even though adolescence is a critical stage in the development of dark triad traits, to date, this construct has not been studied among adolescents, mainly due to the lack of a measurement instrument adapted to this population. (2) Methods: Using a sample of 1642 adolescents, an adaptation of the Short Dark Triad (SD3) is proposed for this population. To this end, we performed a confirmatory factor analysis of the scale and examined its reliability and the intensity of the dark triad components by sex and sexual orientation. (3) Results: The adapted version of the scale (The Short Dark Triad-Adolescent Version; SD3-A) yielded good psychometric results. Confirmatory factor analysis corroborated the theoretical model of the three factors of dark personality. The results confirmed the greater presence of dark traits in male adolescents, and differences were observed based on sexual orientation. (4) Conclusions: The Short Dark Triad-Adolescent Version (SD3-A) is an effective and comprehensive instrument for the estimation of dark traits in adolescents and can be used as a screening test for this population.

Emophilia is a suggested stable phenomenon referring to how often and easily an individual falls in love (Jones, 2011). The current study investigated the psychometric properties of the Emotional Promiscuity Scale (EPS, i.e., a measure of emophilia) and its association with personality traits, romantic relationships, and unfaithfulness in a Scandinavian sample. The sample consisted of 2,607 participants, who were recruited through Norwegian and Swedish newspapers. Descriptive analyses of the EPS and a confirmatory factor analysis (CFA) to verify the previously obtained two-factor structure were conducted. Correlations between emophilia and the Big Five and Dark Triad traits were calculated to investigate the discriminative validity of the EPS. Lastly, negative binomial regression analyses were run in which emophilia comprised the independent variable and the number of romantic relationships and number of times being unfaithful constituted the dependent variables. The EPS had satisfactory internal reliability and the responses to the items were normally distributed. The CFA indicated a two-factor structure, although the two factors correlated highly, justifying collapsing them into one dimension. Emophilia showed satisfactory discriminant validity (r < 00.40) against the personality traits included. Lastly, emophilia was positively associated with the number of romantic relationships and times being unfaithful. Future research should aim to improve our understanding of the psychological and behavioral aspects of emophilia.

UNASSIGNED: Research points to a relationship between owner personality and strength of attachment to one\'s pet, with implications for psychological health. So far, studies in this area, albeit sparse, have focused on the \'Big Five\' traits of owner personality. The \'Dark Triad\' is a cluster of traits that has also been linked to emotional deficits, but has been overlooked in relation to pet attachment. This study therefore examined the association between owner personality and pet attachment, focusing on both the \'Big Five\' and \'Dark Triad\' traits of personality.
UNASSIGNED: A cross-sectional design was employed to collect quantitative data from dog and cat owners across the globe between May-June 2023. A purpose-designed online survey collected sociodemographic details, along with information on pet ownership, strength of the pet-owner bond and participant personality, assessed using the Big Five personality scale and the Short Dark Triad scale. The survey was fully completed by 759 dog and 179 cat owners.
UNASSIGNED: Analysis revealed significant correlations between many of the participants\' personality traits, both within and between scales. Strength of pet attachment was positively correlated with neuroticism and conscientiousness, and, more weakly, to Machiavellianism. Regression analysis revealed that females, dog owners, people over the age of 50 and individuals who had children under 18 years to care for were more strongly attached to their pets than others. Both neuroticism and conscientiousness were found to be significant predictors of participants\' pet attachment scores. None of the Dark Triad traits significantly predicted the criterion.
UNASSIGNED: This study points to a relationship between strength of attachment to one\'s pet and owner personality, at least as measured using the Big Five approach to personality assessment. There was little to support an association between the Dark Triad traits and strength of attachment to one\'s pet, although the link between these characteristics and attachment styles is still unknown. The investigation lends support for the idea that high attachment levels are associated with personality traits aligned to psychological ill-health. Further work is recommended in this area, with a greater focus on both strength and quality (e.g., attachment style) of the pet-owner bond.

UNASSIGNED: The literature suggests that people can accurately infer dark triad (DT) personality traits from other peoples\' faces. Using a self-report scale, this study investigated the impact of participants\' DT personality traits on their ability to accurately infer other peoples\' DT traits from facial cues.
UNASSIGNED: We created composite facial photographs of Japanese people with varying Machiavellianism, psychopathy, and narcissism scores. The Japanese participants (N = 170) assessed these three DT traits in the facial photographs and completed a questionnaire that assessed their own DT traits.
UNASSIGNED: The results indicated that the participants could accurately infer all three DT traits from female faces but not from male faces. Male participants showed a positive correlation between accurate inferences of other men\'s Machiavellianism and their own DT traits. In contrast, female participants showed a negative correlation between correct inferences of men\'s DT traits and their own DT traits.
UNASSIGNED: These findings offer novel insights into human evolutionary and social adaptations.

This study examined the relationship between the actual level of physical violence in sexual offenses and dark triad, empathic and impulsive personality traits of their perpetrators. Sixty-four male perpetrators of sexual offenses without any serious mental illness were included. A 5-point Likert-type coding system based on Violence Profile for Current Offense was applied to assess the severity of physical violence of each sexual offense. Personality traits of dark triad (psychopathy, Machiavellianism, narcissism), trait empathy and impulsiveness were also evaluated. Multivariate analyses indicated that non-stranger victim, secondary psychopathy, narcissism and empathy could significantly predict greater involvement of physical violence in a sexual offense. In addition, empathy was negatively correlated with all dark triad traits. Sexual violence should be conceptualized in the form of a continuum, and, considering such an approach, offenders with high secondary psychopathy and narcissism may show preference for sexual assaults that are more violent in nature.

Conspiracy theories and misinformation (CTM) became a salient feature of the Trump era. However, traditional explanations of political attitudes and behaviors inadequately account for beliefs in CTM or the deleterious behaviors they are associated with. Here, we integrate disparate literatures to explain beliefs in CTM regarding COVID-19, QAnon, and voter fraud. We aim to provide a more holistic accounting, and to determine which political, psychological, and social factors are most associated with such beliefs. Using a unique national survey, we find that anti-social personality traits, anti-establishment orientations, and support for Donald Trump are more strongly related to beliefs in CTM than traditional left-right orientations or other frequently posited factors, such as education, science literacy, and social media use. Our findings encourage researchers to move beyond the traditional correlates of political behavior when examining beliefs that express anti-social tendencies or a deep skepticism of social and political institutions.
