A detailed matrix was developed and key data from each resource were extracted to allow for the assessment of patterns in thematic areas.Results A total of 2108 documents were screened. Overall, 145 documents and 112 tools were reviewed, representing 10 different humanitarian sectors. While numerous resources exist, many lack sufficient information on how to monitor outputs or outcomes of GBV risk mitigation activities. There is also limited guidance on how to integrate the measurement of GBV risk mitigation into existing monitoring and evaluation frameworks. Those reports that aimed to measure GBV risk mitigation activities mostly employed qualitative methods and few measured the impact of a GBV risk mitigation with robust research designs.Conclusions Recent efforts to adapt humanitarian response to COVID-19 have highlighted new and existing challenges for GBV risk mitigation. There is a significant gap in the evidence base around the effectiveness of GBV risk mitigation across all sectors. Understanding and strengthening measurement approaches in GBV risk mitigation remains a critical task for humanitarian response.Data are available upon reasonable request.
