This study aimed to assess the impact of a cyberbullying and victimization prevention program on the self-esteem and cognitive flexibility of adolescents in Osku City Iran. The research followed an experimental design with a pre-test and post-test approach. The study included all female junior high school students in Osku City during the academic year 2023-2024, selected through convenience sampling. Thirty students who had experienced cyberbullying and victimization were randomly assigned into two groups: an experimental group (15 students) and a control group (15 students). Data collection tools included a questionnaire on self-esteem, cognitive flexibility, and experiences of cyberbullying and victimization. The experimental group attended 10 sessions, each lasting 75 minutes, to receive training through the prevention program. Both groups took a pre-test before the sessions and a post-test after the training. The data were analyzed using inferential statistics and covariance analysis, which indicated that the cyberbullying and victimization prevention program effectively improved students' self-esteem and cognitive flexibility. With all research hypotheses confirmed, the strategies and skills taught to address cyberbullying and victimization contribute to enhancing the self-esteem and cognitive flexibility of students. It is recommended that educational administrators, particularly school counselors, organize workshops on cyberbullying and victimization prevention to improve the self-esteem and cognitive flexibility of adolescents.
