This study aims to investigate the drivers of postpartum contraceptive use with a prospective cohort. The study will clarify the role of contraceptive knowledge, attitudes, norms, and self-efficacy in driving intention to initiate contraception postpartum and describe the impact of environmental barriers on enacting intended postpartum contraception initiation.
This study will be a sequential mixed-methods design with a prospective cohort to identify and explore barriers to contraceptive initiation both immediately after birth and prior to hospital discharge, as well as throughout the fourth trimester. It will include a baseline patient survey, electronic medical record data pull, follow up survey, and qualitative interviews.
The investigators will enroll 1400 patients into the prospective cohort, selecting individuals enrolled at prenatal care visits at two sites. The baseline survey will be self-administered. The investigators will then contact participants for a follow-up survey at 12 weeks postpartum. Surveys will be self-administered through a link received by text message or email. Additional analyses will draw on retrospectively collected medical record data.
The investigators will invite a subset of 25-30 study subjects to participate in qualitative interviews.
132 studies on the registry are indexed under Contraception Behavior; 20 are open to participants now.
This study's enrollment of 1,341 is above the median of 149 across 22 observational studies indexed under Contraception Behavior.

The investigators will enroll 1,400 patients into the prospective cohort, selecting individuals enrolled at prenatal care visits at Boston Medical Center and Brigham and Women's Hospital main campus. All subjects enrolled in the baseline survey who deliver at enrollment sites will be included in electronic medical records and contacted for a follow-up survey at 12 weeks postpartum.
Additionally, the investigators will invite a subset of the study subjects (25-30 patients) who report significant barriers to contraceptive uptake in the 12-week postpartum follow up survey to participate in qualitative interviews.
