Many studies have documented widespread contraceptive misinformation circulating on social media platforms, with much concern about the potential impact this has on individuals’ use of and preferences for contraception. Understanding how misinformation operates is crucial to countering its spread. However, little research has explored how contraceptive misinformation is being drawn upon by individuals making contraceptive decisions for themselves or evaluating contraceptive information generally. To fill this gap, we propose an exploratory qualitative study with individuals who have recent experience using contraception. Our study will use three qualitative modalities combined into one research encounter: in-depth interviews, card sorting, and vignettes. By using these three approaches in tandem, we will be able to study the links between misinformation, contraceptive beliefs, and contraceptive decision-making from multiple, complementary perspectives. Our study will generate actionable evidence on how contraceptive beliefs influence contraceptive behaviors, laying the groundwork for the development of interventions that counter inaccurate contraceptive information whether it is intentionally promoted or inadvertently spread. These findings are particularly necessary in the current context, as hostile policy makers’ efforts to curtail access to sexual and reproductive health are bolstered by popularized content that misleads, whether intentionally or as a byproduct of aggressive social media actors who prioritize engagement over accuracy and who are increasingly flooding social media feeds.
