Field-mapping Meta-ethnography

A standard meta-ethnography typically begins with a purposively sampled set of studies and moves directly to translation and synthesis. Field-mapping meta-ethnography adds an upfront mapping stage that systematically characterises the entire body of qualitative research on the topic before selecting studies for synthesis. This reduces selection bias and produces a field map as an additional output.

There is no fixed upper limit, but full reciprocal translation becomes unwieldy beyond 40–60 studies. When field mapping retrieves a larger corpus, researchers typically apply a purposive sampling strategy (selecting theoretically diverse and information-rich studies) for the synthesis stage, while still reporting the full field map.

In a pure scoping review it is optional; in field-mapping meta-ethnography it is recommended because the synthesis makes interpretive claims about what the evidence collectively says. Quality appraisal helps the researcher calibrate confidence in individual study contributions and report limitations transparently.

Use the eMERGe reporting guidance for meta-ethnography (France et al., 2019) for the synthesis component, and adapt PRISMA-ScR (PRISMA extension for scoping reviews) for the mapping component. Some authors use a combined reporting structure that covers both stages.

Qualitative data management tools such as NVivo or ATLAS.ti can help organise extracted data and manage translation notes across a large corpus. The intellectual work of reciprocal translation and third-order synthesis must be performed by the researchers; software handles document management and coding support only.
