Can you share what the KAP survey is to be sure there is not misinterpretation?

Fair question. The KAP stands for the "Knowledge, attitude, and practice surveys". I change in the question too.

KAPs are used in many fields. While I do use them in health-related studies, I first came across KAPs in the livelihoods literature, in which indigenous studies are heavily represented. A search in Google Scholar reveals some examples I have linked:

1. A UNICEF search contains many (medical and non-medical) KAP reports

2. KAPs are referenced in an article on promotion of indigenous knowledge

3. Another article uses KAPs to better understand the coping strategies of refugees in East Africa

4. Another one references KAPs along with other measures of household livelihoods and vulnerability that may measure impacts of and effects on KAP by interventions.

And, a fifth article critiques their use in medical assessments.

One reason you may not find them in studies tagged with the keyword, "ethnography" is that KAPs are intended for rapid, practice-based work and thus gloss some of the information you might achieve through some of the more traditionally ethnographic techniques like long-term participant observation and in-depth interviews.
