The data was collected included Violent Video Game Use Habits Questionnaire, Buss & Perry aggression questionnaire, Adolescent Self Control Dual System Scale and Simple Coping Style Questionnaire.@*Results@#According to the potential profile analysis, the level of aggressive behavior of junior school students in Shanghai could be divided into four groups, which was low aggressive group，middle aggressive group one, middle aggressive group two and high aggressive group according to level of aggregate. After controlling for gender and age, multivariate Logistic regression showed that exposure to violent video games, impulse system and negative response were risk factors for aggressive behavior( P <0.05); using low aggressive group as control group，the OR of violent video games in other three groups were 1.26, 1.30 and 1.70 respectively. The OR of impulse system were 2.96 , 4.40 and 6.84 respectively. The OR of negative response were 1.17, 1.42 and 1.74 respectively. Positive response was a protective factor( P <0.05). Using low aggressive group as control group, the OR of positive in other three groups were 0.82, 0.52 and 0.49 respectively.@*Conclusion@#Violent video game exposure, impulsive system and negative coping style can increase the level of aggressive behavior of junior high school students, while positive coping style can reduce the level of aggression of junior middle school students.
