Sampling and recruitment
During follow‐up visits for the cluster RCT, we invited a random sample of 30 TGW in the peer delivery arm, 15 of their intimate partners and all 10 peers involved in intervention delivery to participate in a qualitative study. Study staff contacted TGW participants and peers to schedule interviews. Intimate partners were invited to participate in interviews through their TGW partners in the research study, who provided their contact details.
