Background Misinformation about abortion is widespread and was exacerbated by the overturn of Roe v Wade. Young adults are among those facing the most direct impacts of new abortion restrictions and are more likely to access health information from online sources, where misinformation is prevalent. We explored how young adults perceive and evaluate abortion-related information in a time of heightened abortion restrictions.

Methods We conducted in-depth, semi-structured interviews with 25 young adults (aged 18–24 years, 56% assigned female at birth), recruited across 17 US states (44% living in states with restrictive abortion policies), between June and September 2022. We derived themes from the interviews using reflexive thematic analysis.

Results While many participants were aware of and had personally encountered abortion misinformation, their susceptibility to false claims varied substantially based on their previous knowledge of abortion and exposure to anti-abortion rhetoric. Participants tended to reject some common myths regarding the medical risks of abortion (eg, association with breast cancer), while expressing a wider range of views regarding its impacts on fertility and mental health. When presented with contradictory sources of abortion information, most participants were unable to confidently reject the misleading source. Knowledge gaps left participants vulnerable to misinformation, while prior scepticism of anti-abortion rhetoric protected participants against misinformation.

Conclusions In this diverse national sample, young adults demonstrated a range of perceptions of abortion misinformation and approaches to identify it. These results lay the groundwork for future observational and experimental research in public health communication.
