Abstract Background A positive childbirth experience is an important outcome of maternity care. A significant component of a positive birth experience is the ability to exercise autonomy in decision‐making. In this study, we explore women's reports of their autonomy during conversations about their care with maternity care practitioners during pregnancy and childbirth. Method Data were obtained from a cross‐sectional survey of women living in The Netherlands that asked about their experiences during pregnancy and childbirth, including their role in conversations concerning decisions about their care. Results A total of 3494 women were included in this study. Most women scored high on autonomy in decision‐making conversations. During the latter stage of pregnancy (32+ weeks) and in childbirth, women reported significantly lower levels of autonomy in their care conversations with obstetricians as compared with midwives. Linear regression analyses showed that women's perception of personal treatment increased women's reported autonomy in their conversations with both midwives and obstetricians. Almost half (49.1%) of the women who had at least one intervention during birth reported pressure to accept or submit to that intervention. This was indicated by 48.3% of women with induced labor, 47.3% who had an instrumental vaginal birth, 45.2% whose labor was augmented, and 41.9% of women who had a cesarean birth. Conclusions In general, women's sense of autonomy in decision‐making conversations during prenatal care and birth is high, but there is room for improvement, and this appeared most notably in conversations with obstetricians. Women's sense of autonomy can be enhanced with personal treatment, including shared decision‐making and the avoidance of pressuring women to accept interventions.
