Online harassment is a growing problem. Among college students, 43% report some experience receiving harassing messages. Previous research has shown negative online experiences to be typical among "emerging adults" (especially college students), and these incidents may be related to normative developmental behaviors, such as "on-again-off-again" romantic relationships. Study hypotheses were derived from previous research. Undergraduate student respondents (N = 342) were surveyed about their experiences with online harassment, emotional responses to online harassment, and their relationship with the sender of harassing messages. Findings suggest that online harassment is linked to issues of intimate partner violence. Those who were harassed by a partner reported feelings of depression and anxiety. Using a gendered framework to explore online harassment is warranted because young women who are 18 to 29 years of age have higher rates of intimate partner violence than other demographic groups. Findings suggest future research is needed to understand the time ordering of these issues.
