This study reports results from cross-cultural comparisons of (a) the frequency of university students' experiences of bullying victimization and perpetration between students, (b) students' experiences of bullying victimization by university personnel, and (c) the breakdown of victimization by the forms of bullying students have experienced. Gender breakdowns are offered. Survey data were collected from undergraduates in a total of 47 universities, using large sample sizes, similar measures and assessment methods in four countries: Argentina (N = 969), Estonia (N = 1053), Finland (N = 4403), and the United States (N = 2072). The results confirmed previous findings which suggest that a notable number of students experience bullying during university studies by fellow students and/or staff members, and a smaller number of students admit to bully their fellow students. The results add to previous knowledge by demonstrating remarkable cultural differences in the prevalence and forms of bullying and suggesting that bullying at the university level starts to transform similar to bullying in the workplace. The overall rates of bullying victimization and perpetration between students were the highest in Argentina, followed by the USA, Finland, and finally Estonia. However, victimization by university personnel was reported the most in Estonia, followed by Argentina, the USA, and Finland. Gender breakdowns in bullying experiences varied between countries. Verbal forms of bullying were common experiences. The most often reported form in all countries was unjustified criticism, belittling or humiliation related to academic performance. Students in the USA reported the highest frequencies in most forms of victimization. The results are discussed by reflecting on higher education features and comparing cultural characteristics of the countries. Practical implications are provided.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.Maili Pörhölä is an adjunct professor in the School of Humanities at the University of Eastern Finland.
