School Climate and Adolescents' Cyberbullying Perpetration: A Moderated Mediation Model of Moral Disengagement and Friends' Moral Identity.

Based on an integration of the positive youth development model and the social cognitive theory, friends' moral identity was examined as a moderator of the direct and indirect relations between school climate and adolescent's cyberbullying perpetration via moral disengagement. Participants were 404 Chinese adolescents (Mage = 13.53 years, SD = 0.92). They completed the Perceived School Climate Scale and the Moral Identity Scale and nominated up to three friends whom they considered to be their "best friend" in their classroom at Time 1. After 6 months, they completed the Moral Disengagement Scale and the Cyberbullying Scale at Time 2. Results showed that adolescents who experienced positive school climate were less likely to cyberbully others, which was mediated by their moral disengagement. Friends' moral identity moderated the direct and indirect relations between school climate and cyberbullying perpetration. Specifically, the indirect relationship between school climate and cyberbullying perpetration through moral disengagement became nonsignificant for adolescents interacting with high moral identity friends. The direct association between school climate and cyberbullying perpetration was moderated by friends' moral identity.
