Addressing contraceptive mis- and dis-information is particularly urgent in states like Mississippi where reproductive health is most threatened by structural oppression. While much research focuses on social media, this is only part of the story, particularly in the Bible Belt where dominance of socially conservative Protestant Christianity creates an enabling environment for disinformation spread by patriarchal movements. Our objective is to identify opportunities for intervention by illuminating what makes people susceptible to believing inaccurate information about contraception in Mississippi. We propose to take a holistic lens focusing on communication among families, peers, religious communities, and online. Drawing on our team’s multi-year collaboration and leveraging expertise in reproductive health education, community-based sampling, and innovative survey methods, we aim to: 1) Test the role of source (peer, family member, preacher/pastor, or social media influencer) in shaping susceptibility to believing inaccurate information via a survey experiment and 2) Explore factors associated with capacity to identify contraceptive misinformation via a misinformation identification exercise. We will identify and survey N=200 Mississippi residents who use or might need contraception. We will use descriptive and inferential statistics to compare beliefs in misinformation by source, magnitude of change in perceived credibility following corrective information by source, correlates of capacity to identify misinformation, and effect measure modification by individual characteristics. We ground the research in multi-level theories: the Elaboration Likelihood Model, Social Norms Theory, and Critical Race Theory. Results will be disseminated locally and nationally to inform the rapidly evolving landscape of strategies to combat contraceptive mis- and dis-information.
