Objective: The study is to explore daily violence exposure and its association with campus bullying, to provide theoretical basis for positive development of middle school students. Methods: Questionnaire survey was conducted by using Violence Exposure Scale, Normative Beliefs about Aggression Scale, Middle School Students’ Self-control Scale, and Middle School Students’ Campus Bullying Scale. During Aug. to Oct. 2019, 1 372 middle school students were selected by the convenient sampling method as subjects of study from 2 junior high schools and 3senior high schools in Xinxiang. Results: The total score in daily violence exposure was (34.22±12.09). The scores of violence exposure, traditional bullying and cyberbullying in female were lower than in male(t=-2.60--6.32, P<0.05). The scores of violence exposure, traditional bullying and cyberbullying in junior high school students were higher than senior high school students(t=4.59-7.50, P<0.05). The relationship between violence exposure and normative beliefs about aggression, traditional bullying, cyberbullying were positive (r=0.20, 0.44, 0.51, P<0.01). The relationship between violence exposure and self-control was negative (r=-0.29, P<0.01) . The relationship between normative beliefs about aggression and traditional bullying, cyberbullying were positive (r=0.28, 0.22, P<0.01). The relationship between normative beliefs about aggression and self-control was negative (r=-0.38, P<0.01). Violence exposure indirectly affects traditional bullying/cyberbullying through normative beliefs about aggression. The effect of normative beliefs about aggression on the traditional bullying/cyberbullying of middle school students is reduced with the increase of self-control. Conclusion Normative beliefs about aggression plays an intermediary role in violence exposure and traditional bully/cyberbullying, and self-control regulates the relationship between them.

Objective: To explore mediating effect of shame on parent-child attachment and bullying among high school students, and to provide the basis for school bullying prevention among high school students.

Results: About 31.07% of the subjects involved in school bullying. The report rates of bullying among boys, high school students of second grade, only child, students from rural area were higher (P<0.01). Mother-child attachment was negatively correlated with traditional and cyber bullying(r=-0.14, -0.21, -0.20, P<0.01). Father-child attachment was negatively correlated with traditional and cyber bullying(r=-0.19, -0.21, -0.19, P<0.01). Shame was positively correlated with traditional bullying and cyber bullying (r=0.20, 0.19, P<0.01). Shame mediates mother-child attachment, traditional and cyber bullying, accounting for 11.78% and 15.70% of the total effects. Shame mediates father-child attachment, traditional and cyber bullying, accounting for 15.17% and 17.43% of the total effect.
