Digital Citizenship Mediates the Inhibitory Effect of Moral Disengagement on Cyber-Bystander Intervention among Young Adults

Abstract

Background: Although cyber-bystander intervention is recognized as a vital deterrent to online aggression, the specific socio-cognitive mechanisms that facilitate such prosocial actions remain under-explored, particularly within non-Western, collectivistic contexts. Grounded in Social Cognitive Theory, this study investigated the inhibitory influence of moral disengagement on "defending the victim" behavioral styles, specifically examining whether digital citizenship serves as the critical mediating bridge in this relationship.

Method: A purposive sampling technique was used based on a cross-sectional and correlational survey design, data were collected from 454 young adult social media users in Pakistan (M_age = 22.81 years; SD = 2.64; 46.3% men, 53.7% women).  Participants completed standardized measures for cyberbullying-specific moral disengagement, digital citizenship, and online defending behavior.

Results: The analyses revealed significant negative correlations between moral disengagement and both digital citizenship and defending behavior. Crucially, path analysis via Hayes’ PROCESS macro (Model 4) demonstrated that the initial significant impact of moral disengagement on defending behavior became non-significant upon the inclusion of the mediator. This pattern indicates full mediation, suggesting that higher levels of moral disengagement undermine an individual’s sense of digital responsibility and civic engagement, which subsequently suppresses the likelihood of victim defense.

Conclusions: The findings suggest that moral disengagement does not operate on bystander behavior in isolation; rather, its inhibitory effect is transmitted through the erosion of digital citizenship. These results advocate for a strategic shift in intervention priorities moving beyond the mere reduction of moral disengagement to the active cultivation of digital ethics and civic responsibility to foster resilient, prosocial online ecosystems.
