Longitudinal Associations Between Violence Exposure and Cyber Aggression in Chinese Adolescents: The Potential Mediating Role of Negative Rumination

This study is the first to reveal a dynamic reciprocal structure among violence exposure, rumination, and cyber aggression using a cross-lagged panel design. Findings suggest that violence exposure contributes to cyber aggression both directly and indirectly via cognitive-emotional processes. The results offer a theoretical framework and time-sensitive window for cyber aggression prevention in Chinese adolescents.
