Technology-facilitated gender-based violence (TF GBV) is an act of violence perpetrated by one or more individuals that is committed, assisted, aggravated and amplified in part or fully by the use of information and communication technologies or digital media, against a person on the basis of their gender. This paper aims to guide the discussion of key considerations relevant to the measurement of TF GBV, and is informed by a rigorous scoping review of approaches, tools, instruments and questions used to measure TF GBV.
