Objective: To explore the relationship between childhood abuse and cyberbullying among college students and to provide theoretical support for early intervention of cyberbullying among college students. Methods: A total of 3 850 sophomores and juniors from 6 universities in Shanxi Province, randomly selected by stratified cluster sampling method, were investigated by using the Questionnaire on Cyberbullying and the Chinese Version of the Child Abuse Questionnaire. Results: Male students reported higher rates of sexual abuse, emotional neglect and physical neglect than female students(χ2=5.22, 4.39, 7.53 P<0.05). The child abuse report rate of college students whose parents divorced was higher than that of those whose parents were not divorced(χ2=86.80, 134.06, 130.18, 175.64, 118.46，P<0.05). In addition to physical neglect, childhood abuse rate of only children was higher than that of non-only children, with statistically significant differences(χ2=9.44, 12.44, 21.18, 21.26, all P<0.05). The scores of all factors and total scores of cyberbullying implemented by male students were higher than those by female students(t=9.35, 5.59, 5.83, 7.57，P<0.05); the scores of all factors and total scores of cyberbullying implemented by only-child students were higher than those by non-only-child students(t=2.79, 3.74, 4.78, 4.40，P<0.05); the scores of all factors and total scores of cyberbullying implemented by students whose parents were divorced were higher than those by students whose parents were not divorced, with statistically significant differences(t=6.99,6.78, 8.04，11.33, P<0.05). Multiple linear regression model showed that there was a positive correlation between the childhood abuse of college students and the implementation of cyberbullying, and regression coefficient differences of all factors were statistically significant(β=0.10, 0.11, 0.05, 10.08,0.06, P<0.05). Conclusion Childhood abuse experiences increase the risk of college students practicing cyberbullying.
