Qualitative methods and analyses
The overall objective of the qualitative study was to analyse local experiences and interpretations of the four housing modification types, and to understand the elements of the local context that shaped acceptability, as well as concerns about, or rejection of, the interventions among households.The qualitative study comprised ethnographic observations, focus group discussions, and key informant interviews. The analysis took a poststructuralist approach and were interested in the interconnections that emerged between the study components and the local context. The housing modifications were conceptualized as ‘assemblages’, and explored how the practices, logics, and material resources embedded in the pilot study interacted with and were re-interpreted within the local context [The qualitative team was separated from the main trial team in terms of day-to-day activities and supervision. The researchers collecting qualitative data were never involved in collecting trial data nor sensitizing or mobilizing the community. All qualitative researchers were mentored by an anthropologist based in the UK, who supported decision making around data collection; writing fieldnotes; analysing and interpreting data; and writing up.
