Associations between social media and cyberbullying: a review of the literature.

Cyberbullying is a significant public health concern that can lead to increased risk of mental health issues, including psychological and developmental problems or suicide. However, because cyberbullying is a relatively recent phenomenon, there is a lack of agreement among researchers about the definition and prevalence of cyberbullying as well as methods for measuring its prevalence. In this review, we evaluate papers published between January 2013 to August 2015 that explored cyberbullying through the medium of social media. The aims of the study are to (I) clarify the characteristics of people involved in cyberbullying, and (II) identify the types of instruments used to measure cyberbullying on social media. In particular, we attempt to understand the factors underlying abuser behavior, how abusive behavior affects the well-being of victims, and how bystanders mitigate or contribute to the act of cyberbullying.
