Abstract: | The present study investigated the relations between the Dark Triad personality
traits (i.e., Machiavellianism, narcissism, and psychopathy), distinct dimensions of selfdisclosure
online (i.e., honesty, amount, positive valence, and intent) and selÞ e relatedbehaviours
(taking, posting, and editing selÞ es). The results indicated, that all three
Dark Triad components were positively correlated with posting and editing selÞ es on
social networking sites (SNSs). However, multiple regression analysis demonstrated
that only narcissism predicted selÞ e-related behaviours. Narcissism and Machiavellianism
were positively related to the amount of personal information disclosed online
and the tendency to intentionally self-disclose in a computer-mediated communication
(CMC). Moreover, we found no signiÞ cant correlations between the perceived controllability
of Internet communication and two types of self-promotion in the Internet
(self-disclosure online and selÞ e-related behaviours). Our Þ ndings demonstrate the
importance of analysing the ‘dark’ personality traits in the context of self-promotional
behaviours in social media. |
