Roughly 20% of women in the USA will seek an abortion during their lifetimes. As abortion is a medical procedure, individuals seeking abortion services must have access to accurate medical information. Inaccurate information about abortion, known as abortion misinformation, adversely affects knowledge about abortion, and may impair informed decision-making. Abortion misinformation has received limited attention in psychological and health research. This review summarises current findings on abortion misinformation from studies of adults in the USA, examines which forms of misinformation are most common, and assesses prominent sources of abortion misinformation. A narrative, integrative approach was adopted focussing on nine articles. Findings suggest that first, inaccurate beliefs about abortion exist among many samples of US adults, including inaccurate connections between abortion and breast cancer, infertility and negative mental health outcomes. Second, abortion misinformation comes from a variety of informational sources, which may render efforts to prevent it challenging. Summarising and extending knowledge of abortion misinformation may be useful first steps to better understanding this phenomenon and may ultimately aid in reduction of abortion misinformation among individuals living in the USA.
