Also, test-retest correlation coefficients for the total scale and its subscales ranged from 0.76 to 0.84. Internal consistency for the total scale and its subscales ranged from 0.68 to 0.88.Conclusion: Dark tetrad Personality traits model is confirmed among Iranian sample and has a good fitness to data.

The Dark Personality traits have expanded as a new and integrated model of combining existing Personality theories and in the last decade, it has attracted a lot of attention in the field of Personality pathology models. The purpose of this study was to investigate the role of pathological Personality dimensions in predicting Dark tetrad Personality traits. For this purpose, 400 people (226 women and 174 men) were selected from the students of Tabriz universities by convenience sampling and were evaluated in terms of Dark tetrad Personality traits and the pathological Personality dimensions. The results of multiple regression analysis showed that the five dimensions of pathological Personality including negative affectivity, detachment, antagonism, disinhibition and psychoticism are related to the Machiavellianism, narcissism, psychopathy, Sadism. The results showed that Machiavellianism predicted by antagonism; psychopathy predicted by antagonism and detachment; narcissism predicted by antagonism, detachment and negative affectivity; Sadism predicted by antagonism. It is noteworthy that antagonism as one of the pathological Personality dimensions predicted all four Dark Personality traits. It can be concluded that the Dark Personality traits can be rooted in maladaptive Personality dimensions and aspects.

The aim of this study was to determine the relationship between Dark triad Personality traits and online self-disclosure. The present research is a correlational type of study. The population of the present study includes all B.Sc students of Mohaghegh Ardabili University, among them three hundred and seventy-five students (175 female and 200 male) were selected, using proportion- stratified random sampling method. They were asked to respond to self-disclosure (attitudes, interests, study, money, Personality and body) and Dark Triad Personality (Narcissism, Machiavellism and Psychopath) Questionnaire. The collected data were analyzed using Pearson correlation and stepwise multiple regression. The results of Pearson correlation showed that there were positive correlations of machiavelism with subscales of study/work, Personality, body and total self-disclosure, and psychopath with subscales of body and total self-disclosure. Finally the results showed that there were positive correlations of narcissism with subscales of interest and study/work, Personality, body and total self-disclosure. The results of stepwise multiple regression analyses showed that among three Dark Personality traits, two Personality traits, narcissism and machiavellism, were predictors of online self-disclosure. According to the results of the present study, the role of two Dark triad personalities, narcissism and machiavellism, on internet self-disclosure was confirmed. This result can help internet users, especially students, to discover interests and Personality characteristics of individuals with high internet self-disclosure in cyber atmosphere and increase knowledge and predict exploitation of these people.

The obtained data were analyzed by SPSS using Pearson correlation coefficient and multiple regression analysis. Ethical Considerations This study was approved by Research Ethics Committee of Guilan University of Medical Sciences (Code: IR. GUMS. REC. 1398. 121). Results The present research results suggested a positive and significant correlation between the resilience of the examined athletic students and narcissism (r=0. 495, P<0. 001), self-acceptance (r=0. 598, P<0. 001), purposefulness in life (r=0. 556, P<0. 001), personal growth (r=0. 648, P<0. 001), the mastery of the environment (r=0. 645, P<0. 001), positive correlation with others (r=0. 569, P<0. 001), and independence (r=0. 381, P<0. 001). Moreover, there was a significant negative correlation between antisocial behavior (r=-0. 557, P<0. 001) and Machiavelli’ s aspect (r=-0. 604, P<0. 001), and the explored students’ resilience. Additionally, multiple regression analysis data revealed that Dark triad Personality and psychological wellbeing predict 62% of resilience in the study subjects. Conclusion The current investigation results signified a significant correlation between Dark triad Personality and psychological wellbeing, and resilience in athletic students. Accordingly, educators and teachers need to pay more attention to the role of psychological wellbeing and different dimensions of athletes’ personalities for promoting the health and performance of students.

Background: Management Personality is one of the critical factors influencing their behavior in performing earnings management (EM). As a result, the Dark (negative) Personality dimensions can play an effective role in earnings management. On the other hand, ethical leadership can act as a moderating factor; this research measures the effect of ethical leadership style on reducing Dark Personality dimensions (Machiavellianism, psychopathy, narcissism) of effective person in earnings management.

The statistical population of this study is companies listed in the Tehran Stock Exchange (TSE) and Iran Fara Bourse (IFB) from 2011 to 2019 and based on some limitations 77 companies used in this research for testing the hypotheses. And standard questionnaires of Dark Personality and ethical leadership and financial statement data have been used.
