The aim of this study was to determine the prevalence of harassment in high school and into university, and the impact of one particular form of harassment: cyber-harassment. Participants were 1,368 students at one US and two Canadian universities (mean age ¼ 21.1 years, 676 female students). They responded on five-point scales to questions about the frequency and impact of harassment. A total of 33.6% of students stated they had been cyber-harassed and 28.4% had been harassed off-line when in high school. Also, 8.6% were cyber-harassed and 6.4% were harassed off-line while in university. Hierarchical logistic regression analyses show that the type of harassment experienced in high school is associated with the type of harassment experienced in university. Various negative outcomes of cyber-harassment were also identified.
