Randomization and masking
HIV status disclosure
SECONDARY
Computer-generated simple randomization was used to assign clients to either the PRS or HIVST arms in a ratio of 1:2·5, respectively. We intentionally randomized more clients to the HIVST arm to examine associations between key client–partner relationship dynamics and implementation outcomes in the treatment group (such as acceptability and feasibility of HIVST distribution, HIVST use and any changes to relationship dynamics, not included in this paper). Relationship dynamics of most interest include: relationship type (i.e., married or cohabitating), HIV status disclosure (or not), and decision-making dynamics within the relationship. The secondary analysis is important to identify if unique implementation strategies should be considered for different relationship dynamics, should the intervention be successful. This was a non-blinded trial therefore masking was not included.
