Abstract: To explore the heterogeneity of aggressive behaviors and their influencing factors among 8th-grade students, this study classified 613 8th-grade students using latent profile analysis, and analyzed the relevant influencing factors through non-parametric tests and multinomial logistic regression. The results showed that the aggressive behaviors of 8th-grade students could be divided into four subcategories: the marginal aggressive group, the physical aggression dominant-low verbal aggression group, the non-aggressive group, and the high aggressive group, with significant differences in aggressive dimensions among these categories. The analysis of influencing factors indicated that exposure to media violence increased the risk of being in the physical aggression dominant-low verbal aggression group; students with abnormal parental marital status had a higher risk of being classified into the high aggressive group; family economic conditions played a protective role in the marginal aggressive group; and the regional environment also had potential impacts. This study provides a theoretical basis for the precise prevention and intervention of adolescents' aggressive behaviors.
