Women randomized to the trauma informed obstetric care (TIOC) intervention will be scheduled for all their prenatal appointments with obstetricians trained in the TIOC model. Additionally, the midwife on duty in the delivery ward will ensure that all items on a checklist of trauma-sensitive birth practices are followed during that participant's labor and delivery

Participants randomized to TAU will receive usual prenatal care, which includes a referral to psychological services when deemed necessary by the prenatal care provider. These participants' prenatal visits will not be scheduled with providers who have received TIOC training.

TIOC providers will receive a training that was developed for this study. Elements of trauma-informed care described in the literature -combined with the experience of the study team, with deep expertise in trauma-informed obstetric care, were used to create three training modules, each of which includes didactics and role-plays to help participants practice and embody skills they learn. The three modules are:

1. Effects of trauma on physiological and psychological process relevant to pregnancy and childbirth.
2. Body language and verbal language for safety, respect, and patient agency
3. Recognizing and responding to distress and dissociation

Depression and anxiety symptoms during pregnancy will be measured by the EPDS. The scores range from a minimum of 0 to a maximum of 30. The total score reflects the level of depression, with higher scores indicating higher depression.

Perceived stress during pregnancy will be measured by the PSS. Scores range from a minimum of 0 to a maximum 40. The total score reflects the level of stress during pregnancy, with higher scores indicating higher stress.

Maternal Attachment Feelings toward fetus during pregnancy will be measured by the MAAS. Scores range from a minimum of 19 to a maximum of 95. The total score reflects maternal attachment, with higher scores indicating higher maternal-fetal attachment.

The mother's experience of care provided will be measured by the CARE Scale. Scores range from a minimum of 10 to a maximum of 50. The total score reflects the level of perceived empathy, with higher scores indicating higher empathy.

Pregnancy-specific distress will be measured by the PDQ. Scores range from a minimum of 0 to a maximum of 34. The total score reflects the level of prenatal distress, with higher scores indicating higher levels of prenatal stress.

The mother's experience of childbirth will be measured with the Childbirth Experiences Questionnaire. The total score ranges from 1 to 4, with 1 indicating positive experiences of childbirth and 4 indicating negative experiences of childbirth.
