The study aimed to identify the factors and motivations that lead cyberbullied adolescents to engage in cyberbullying and to develop a structural model of the interrelationships between cyberbullying, moral disengagement, and bullying motivations. The primary research sample consisted of 804 adolescents from High schools in the Kingdom of Saudi Arabia, with 302 adolescents identified as cyberbullies, aged between 16 and 19 years (M= 18.9, S.D= 1.6). The sample was obtained through electronic links distributed via email and social media platforms. The study used the Cyberbullying Questionnaire (CBQ-Bullying scale), Cyberbullying Moral Disengagement Scale, and Cyberbullying Motivations Scale. The findings of the study indicate that power and ideology are the most significant factors causing cyberbullying behavior from the perspective of cyberbullies, followed by instrumental, amusement, sadism, external factors, revenge, and finally moral disengagement. There are differences between males and females in cyberbullying factors that favor males. Furthermore, the findings revealed that cyberbullying motivations and moral disengagement are positive predictors of cyberbullying behavior. Using structural modeling, the study confirmed the mediating role of power and moral disengagement variables in the influence of other factors like ideology, revenge, amusement, and sadism on cyberbullying behavior, in addition to the direct effects of the variables of instrumentality, ideology, and revenge on cyberbullying.
