Interviews with study participants
RECRUITMENT
Semi-structured interviews will be conducted with between 15 and 25 women recruited from the trial population. Written informed consent for interviews will be obtained at the same time as participants are consented into the trial. Interviews will be conducted around 6–8 weeks post-partum, will take place either face-to-face or by telephone, and will last approximately 30–45-min duration. Using a maximum diversity sampling approach, we will aim to recruit women who: completed the study and those who dropped out; those from different recruitment sites; those for whom this is their first birth versus those who had previous pregnancies; those with different genotypes, which may affect treatment experience.
