There is increasing global pressure to ensure that pregnant women are responsibly and safely included in clinical research in order to improve the evidence base that underpins healthcare delivery during pregnancy. One supposed barrier to inclusion is the assumption that pregnant women will be reluctant to participate in research. There is however very little empirical research investigating the views of pregnant women. Their perspective on the benefits, burdens and risks of research is a crucial component to ensuring effective recruitment. The Research In Pregnancy Ethics (RIPE) study set out to ascertain the views of pregnant women about research participation using an inductive thematic analysis. We conducted semi‐structured interviews with 20 women who had participated in a double‐blind randomised placebo controlled trial in Wellington (New Zealand) while pregnant. Our results show that at least some pregnant women recognise the value and importance of research during pregnancy. The women we interviewed were deeply invested in the research process and outcomes. Key motivations for participating were altruism, playing a valuable civic role and the importance of research. The main perceived burdens related to inconvenience and time commitment. For some women, possible randomization to the placebo arm was regarded as a burden or disadvantage.
