Existing approaches to quantitative epidemiologic methods commonly used in conflict and other emergency settings risk retraumatizing research participants. However, little guidance exists regarding how to mitigate these risks. Here we draw on literatures addressing ethical considerations in 2 similar activities—the use of qualitative research methodologies in research with survivors of violence and trauma, as well as witness protection strategies during tribunal proceedings. We recommend preliminary standards and best practices for participant protection from retraumatization associated with quantitative epidemiological methods adapted from existing practices for qualitative research and in tribunal contexts that should be refined in partnership with the affected communities.
