Couples' decision making regarding the use of multipurpose prevention technology (MPT) for pregnancy and HIV prevention.

We conducted a secondary analysis of discrete choice experiment (DCE) data from 395 couples enrolled in the Microbicide Trials Network (MTN)-045/CUPID study in Uganda and Zimbabwe to understand couple decision making around choice of multipurpose prevention technologies (MPTs) to prevent both HIV and pregnancy. Members of couples completed the same DCE, first separately then jointly, choosing between two hypothetical MPTs in a series of nine questions. Most couples either had similar preferences at the outset or had equal decision-making around MPTs (62%). Couples with male influence (17%) were more likely to use contraceptive pills with a male partner's knowledge and couples with female influence (21%) were less likely to have shared decision making about family planning. Males influenced discussion around MPT duration, side effects, menstrual changes, and how the vagina feels during sex. Decision making was relatively shared, though decisions around certain attributes were more likely to be dominated by male partners.
