Results: (1) Childhood psychological abuse was significantly positively correlated with cyberbullying perpetration attitudes and showed a significant negative correlation with positive moral personality traits. (2) Positive moral personality traits had a significant negative correlation with cyberbullying perpetration attitudes.
