Participant recruitment and informed consent

Twenty-one CHWs with ≥2 years of experience working in Msinga were recruited by phone for participation in one of three focus groups.²¹ To provide a sample with broad geographic representation of the Msinga neighborhoods, these participants were purposively selected from a list of all 51 CHWs working for the aforementioned local NGO's home-based care branch.²¹ Since it was founded in 1999, this NGO has been employing CHWs for community outreach, with a particular focus on HIV/AIDS. Thus, the CHWs interviewed represent a convenience sample. Participants gave written informed consent allowing focus group interviews to be recorded and were reimbursed for travel expenses.
