In-depth interviews were administered using face-to-face using interview guides. The interviews were conducted in English or Luganda and audio recorded with the prior permission of study participants. Prior to the interviews, the details of the study were explained to the study participants and informed consent/assent was sought, where they were asked to sign a hard copy consent form.
For focus group discussions, participants were stratified by village, training and gender. Each focus group consisted of approximately six to eight participants. Focus groups were conducted by a facilitator and co-facilitator, who observed and took notes. Prior to the start of the focus group, the facilitator and co-facilitator obtained consent/assent from respondents to participate in the study and to audio-record the discussion. The facilitator used a semi-structured focus group guide to ensure that all components were discussed, but encouraged participants to elaborate through probes. The facilitator and co-facilitator debriefed at the end of the focus group to discuss themes that emerged during the discussion. Using the notes and encrypted audio-recording, the co-facilitator organised and cleaned the focus group notes, reviewed them for clarity, and added their reflections on the process, including barriers and facilitators to data collection. Co-facilitators’ notes were be used to supplement the transcripts.
