In Missouri, abortion access has dramatically changed in recent years. Following the Supreme Court’s 2022 decision in Dobbs v. Jackson Women’s Health Organization, Missouri enacted a near-total abortion ban, only for voters to pass Amendment 3 in 2024, enshrining abortion rights in the state constitution. Now, a new ballot measure threatens to undo that progress. For pregnant people navigating this uncertainty, knowing where to turn for support is not always straightforward. Abortion doulas, or trained community members who provide emotional, informational, and logistical support throughout the abortion process, have become increasingly important in helping people access care in this shifting landscape. Despite their critical role, almost nothing is known about what it is like to be an abortion doula in a state where the law keeps changing. This study will interview abortion and full-spectrum doulas in Missouri to understand how they support clients navigating care access in this volatile environment, what gets in the way of that support, and how doulas’ own identities shape who they are able to reach and how. Findings will be shared with Missouri doula organizations, public health advocacy organizations, and state policymakers. The goal of this work is to build the evidence base for recognizing and investing in abortion doulas as essential partners in reproductive healthcare, particularly in states where access to formal abortion services is limited or unclear.
