Purpose:The purpose of this study was to identify the interpersonal problems and mental health of college students according to their experience of bullies and of being victims of bullying in childhood and adolescence. Methods: The questionnaire was completed by 221 college students in J city. Data were collected during November and December, 2015. The data were analyzed and interpreted using descriptive statistics and ANOVA with the PASW Statistics 18.0 program. Results: Nearly 65% of participants reported having experienced bullying victimization, bullying perpetration when they were in elementary, middle or high school. Interpersonal problems were significantly different between victims or victim-perpetrator and a control group (F=13.12, p<.001). Mental health was significantly different between victims, perpetrator or victim-perpetrator and a control group, (F=13.15, p<.001). Conclusion: Participants commonly reported experiencing bullying while at school and these reports were associated with higher interpersonal problems and lower levels of mental health. Bullying experience needs further investigation as a preventable cause of interpersonal problems and mental health problems across the lifespan.
