ABSTRACT
This chapter examines three common forms of online interpersonal violence: cyberbullying, online harassment, and cyberstalking. It discusses the common definitions used by researchers and practitioners for these offenses, and considers estimates of both victimization and offending, and the emotional and psychological impact that they have on victims. The factors that may affect victim reporting will also be discussed to better understand why these offenses may be underrepresented in various data sources. The connection between on- and off-line victimization may stem from the fact that bullies who know their victim in the real world may more easily target that person via information communications technologys (ICTs). Research on rates of cyberbullying victimization demonstrate the substantial limitations of the current measurement techniques available. Research examining the prevalence of online harassment and cyberstalking is somewhat better than that of bullying, due to the number of representative national population samples developed by researchers.
