| With the continuous development of information technology,network,as a double-edged sword,has not only become an important medium for contemporary middle school students to learn,exchange and consult information,but also has a great negative impact on junior middle school students.At present,studies have shown that cyberbullying and cybervictimization have a significant impact on the mental health of teenagers.At present,This study investigates the current situation of junior high school students’ cyberbullying,cybervictimization,rumination,normative beliefs about aggression and a dimension of emotion regulation strategies-cognitive reappraisal,and explores the influence mechanism of junior high school students’ cyberbully victimization,rumination,attacking normative belief and cognitive reappraisal on online bullying,so as to provide theoretical and practical basis for educators to carry out mental health education activities related to cyberbullying.The research used the "The Revised Cyber Bullying Inventory","Ruminative Responses Scale","The Normative Beliefs about Aggression Scale" and "Cognitive Reappraisal Subscale" to conduct a questionnaire survey of 1004 junior high school students.The result shows:(1)Cyberbullying,cybervictimization and cognitive reappraisal of junior high school students have significant differences in home address;rumination has significant differences in gender,and normative beliefs about aggression have significant differences in gender and grade.(2)Cyberbullying is significantly positively correlated with cybervictimization,rumination,and normative beliefs about aggression,and significantly negatively correlated with cognitive reappraisal;cybervictimization is significantly positively correlated with rumination,normative beliefs about aggression,and cognition Re-evaluation showed a significant negative correlation.(3)Cyberbullying,cybervictimization,rumination and normative beliefs about aggression can form a chain mediation model.(4)Cognitive reappraisal plays a moderating role in the direct path of cyberbully victimization to cyberbullying,while cognitive reappraisal has no significant moderating effect in the first half of the mediating role of rumination and normative beliefs about aggression.Through the analysis of the research results,this research draws the following conclusions:(1)Junior high school students have a high degree of cybervictimization,rumination and normative beliefs about aggression,which are likely to lead to cyberbullying.The existence of cognitive reappraisal helps reduce the incidence of cyberbullying.(2)Rumination and normative beliefs about aggression can explain the internal mechanism between cybervictimization and cyberbullying among junior high school students,and the existence of cognitive reappraisal explains why individuals who have experienced cyberbullying do not necessarily have bad emotions and behaviors. |
