To figure out why respondents are not using bednets, I’d rather start from literature review. This topic is quite common problem, about mosquito related disease prevention. So, there might be previous published literature in large database such as Pubmed, for the reason or barriers to bednets or mosquito net use. Then with those information, probably there are main factors such as , social factor, individual factor, environment/temperature factors, and bednets availability, we can further dig and sort out the proper approach for particular factors in the list. Then we can conduct a cross-sectional survey of barriers or factors in not using bednets, we will get quantitative data. For understanding more on some factors, we can now conduct some qualitative data for example in-depth interview with head of the village, focus group discussion with those who use and those who do not use the bednets.
