Birth Cohort Effects, Regions Differences, and Gender Differences in Chinese College Students’ Aggression: A Review and Synthesis

Abstract

This cross-temporal meta-analysis involved 86 studies (N = 71,397) on aggression among Chinese college students conducted from 2003 to 2017. We collected articles investigating college students’ aggression using the Aggression Questionnaire. The results showed that college students’ aggression generally decreased steadily over 15 years. Compared to 2003, aggression in 2017 decreased by 1.030 standard deviations. The decline in physical aggression, verbal aggression, and hostility among college students were more rapid than anger. College students from the Eastern region of China demonstrated this decline more than those from the Center and Western regions. Both male and female college students showed decreasing aggression, and the decline was larger in males compared to females.
