The Longitudinal Relationship between Cyberbullying Victimization and Loneliness among Chinese Middle School Students: The Mediating Effect of Perceived Social Support and the Moderating Effect of Sense of Hope.

Compared with traditional forms of bullying (e.g., physical bullying, verbal bullying), cyberbullying victimization can bring heavy psychological damage to the victim of bullying. Studies have found that cyberbullying victimization leads to higher levels of depression and causes anger and emotional problems. Nevertheless, existing studies mainly focus on traditional bullying while affording scant consideration to the longitudinal impact of cyberbullying on mental well-being. The purpose of this study was to examine the effects of cyberbullying victimization on middle school students' loneliness while simultaneously investigating the mediating role of perceived social support and the moderating role of feelings of hope. A total of 583 middle school students were surveyed using four self-report questionnaires. Cyberbullying victimization predicts loneliness. Perceived social support mediates the role of cyberbullying victimization in influencing cyberbullying. Sense of hope moderated the direct pathway and the second half of the mediating role pathway. First, many mediating and moderating variables of cyberbullying victimization affect loneliness, and different mediating and moderating variables can be studied in the future. Second, future studies could expand this study's sample to validate the results of this study. Third, this study only collected data at two time points, and future studies could collect data at multiple time points. Cyberbullying victimization can increase loneliness over time. Perceived social support and a sense of hope can mitigate the effects of cyberbullying victimization on an individual's mental health.
