Cyberbullying was defined as using technology to harm, humiliate, and exclude others intentionally. Identifying the antecedents of cyberbullying perpetration is crucial to reduce cyberbullying and to eliminate the detrimental consequences of cyberbullying victimization. So far, very little attention has been paid to the antecedent of cyberbullying. Evidence suggests that the Dark Triad (DT) personality traits (psychopathy, narcissism and Machiavellianism), are among the most important antecedents of cyberbullying perpetration. The current meta-analysis aimed to investigate the effects of the DT Personality Traits on cyberbullying perpetration with the moderating role of participants’ age group. Relevant databases (i.e., Google Scholar, PsycINFO, ProQuest, Wiley Online Library, Scopus, Science Direct, Web of Science) were systematically reviewed. Only studies are written in Turkish and English, and studies that reported at least one Pearson correlation coefficient between study variables were included. In total, 22 study findings were integrated (k = 22, N = 12967 for Machiavellianism - cyberbullying; k = 24, N = 12533 for narcissism - cyberbullying; and k = 18, N = 10885 for psychopathy - cyberbullying). Study samples were comprised of adolescents, university students and adults. In the current study, a random-effect model was conducted through the R package. DerSimonian- Laird estimator was used to estimate the variance of the true effects. All analyses were performed with Fisher Z scores, which were translated from Pearson correlation coefficients (r). Finally, findings were converted back to the Pearson correlation. The findings revealed that the overall effect sizes of psychopathy, narcissism and Machiavellianism on cyberbullying were significant (r = .36, p < .001; r = .22, p < .001; r = .31, p < .001; respectively). Furthermore, the moderating role of participants’ age group in the link between psychopathy and cyberbullying was found to be significant. However, the moderating role of participants’ age group in the association between the other variables was found as insignificant.
