We think this was due to some combination of:

1) insufficient training of interviewers (squarely on me)
2) non-comprehension of reverse-coded questions (low education attainment)
3) non-transferability of scale items to these communities

In-depth ethnography highlighted that our surveys - one part of a wider quantitative questionnaire, one during the ethnographic process - missed key aspects of health limitations. Esp about functional limitations vs diagnosed disease

Tl; dr We needed to do better scoping these survey questions
