This study aimed to investigate the relationship between witnessing university violence and developing posttraumatic stress disorder (PTSD) among university students. A total of 885 students from Hashemite University participated in the study. A self-administrated questionnaire and the PTSD Interview Schedule were distributed. The study revealed a low to moderate prevalence of PTSD symptomatology among the study sample; there were significant differences in PTSD prevalence based on faculty type, personal traumatic history, living situation, injuries resulting from university violence, students' violence involvement, and short duration of witnessing violence. There were no statistical differences in PTSD prevalence based on gender and type of degree.
