The present study was aimed to investigate the relationship between dark personality traits and cyberbullying through the mediation of moral indifference and impulsivity in students. The research method was descriptive_correlational, path analysis type. The research population was all high school students in Tabriz in 2024, from which 388 individuals were selected as a sample through multi_stage cluster random sampling. The tools of this study included the Cyber-Bullying/Victimization Experiences Questionnaire (CBVEQ) by Antoniadou et al. (2016), the Dirty Dozen scale (DDS) by Johnson and Webster (2010), the Mechanisms of Moral Disengagement Scale (MMDS) by Bandura et al. (1996), and the Barrett Impulsivity Scale (BIS-11) by Patton et al (1995). The fit indices showed that the final model had a good fit. The direct effect of Machiavellianism and antisociality on cyberbullying (P<0.01) was significant. the direct effect of narcissism on cyberbullying, machiavellianism on impulsivity, narcissism on impulsivity and antisociality on moral indifference were not significant (P>0.05). the indirect effect of machiavellianism and narcissism through moral indifference and antisociality through impulsivity on cyberbullying was significant (P<0.01). As a result impulsivity and moral indifference play an important role in cyberbullying and mental health professionals can rely on this model to design necessary therapeutic interventions.
