For me, I would first conduct a thorough search for any existing research in the same area. Ideally, I would uncover previously studied information that would save time and resources. However, if I am unable to find suitable research, I may need to conduct additional qualitative studies.
I think, prioritizing between the depth of information required and the time it takes is crucial. In cases where the information is highly sensitive and requires in-depth analysis, conducting an in-depth interview is necessary. However, when it comes to data on the use of bednets, which is not highly sensitive, I will begin by launching an open-ended questionnaire to comprehend why most people choose not to use bednets. Subsequently, I will categorize the reasons and conduct focus group studies to discuss them in each group.
