Does Sensation Seeking Lead to Adolescents' Cyberbullying Perpetration? The Mediating Role of Moral Disengagement and The Moderating Role of Perceived Social Support.

Based on the general aggression model, the current study examined the mediating role of moral disengagement in the association between sensation seeking and cyberbullying perpetration and the moderating role of perceived social support. A total of 2,286 Chinese adolescents aged 11-16 years completed the questionnaires regarding sensation seeking, cyberbullying perpetration, moral disengagement, and perceived social support. After gender and age were controlled, sensation seeking was significantly and positively associated with cyberbullying perpetration and this relationship was partially mediated by moral disengagement. Moderated mediation analysis further indicated that perceived social support moderated the relationship between sensation seeking and moral disengagement as well as sensation seeking and cyberbullying perpetration. These two relationships became weaker for adolescents with high perceived social support. Specifically, adolescents with higher levels of sensation seeking were more likely to develop moral disengagement and further engaged in cyberbullying perpetration, when they perceived less social support.
