In 2011, Sarah McMahon and colleagues published “The Impact of Emotional and Physical Violence During Pregnancy on Maternal and Child Health at One Year Post-partum,” hereafter, “The Impact,” in the journal, Child and Youth Services Review. While existing studies had indicated negative chronic effects resulting from intimate partner violence, or IPV, such as miscarriage and premature labor, there was little research specifically analyzing the separate and joint effects of psychological and physical abuse on pregnant women and fetuses. The authors reported that both physical and emotional IPV had negative impacts on the woman and child at one-year after birth, including worse overall health and increased likelihood of depression. In “The Impact,” the researchers analyzed the effects of partner abuse during pregnancy, distinguishing between the effects of emotional abuse and physical abuse on health outcomes for a pregnant woman and her offspring.
