Abortion and mental health

Scientific and medical expert bodies have repeatedly concluded that abortion poses no greater mental health risks than carrying an unintended pregnancy to term. Nevertheless, the relationship between induced abortion and mental health is an area of political controversy. In 2008, the American Psychological Association concluded after a review of available evidence that induced abortion did not increase the risk of mental-health problems. In 2011, the U.K. National Collaborating Centre for Mental Health similarly concluded that first-time abortion in the first trimester does not increase the risk of mental-health problems compared with bringing the pregnancy to term. In 2018, The National Academies of Sciences, Engineering, and Medicine concluded that abortion does not lead to depression, anxiety, or post-traumatic stress disorder. The U.K. Royal College of Obstetricians and Gynaecologists likewise summarized the evidence by finding that abortion did not increase the risk of mental-health problems compared to women carrying an unwanted pregnancy to term. Two studies conducted on the Danish population in 2011 and 2012 analysed the association between abortion and psychiatric admission found no increase in admissions after an abortion. The same study, in fact, found an increase in psychiatric admission after first child-birth. A 2008 systematic review of the medical literature on abortion and mental health found that high-quality studies consistently showed few or no mental-health consequences of abortion, while poor-quality studies were more likely to report negative consequences.

Despite the weight of scientific and medical opinion, some anti-abortion advocacy groups have continued to allege a link between abortion and mental-health problems. Some anti-abortion groups have used the term "post-abortion syndrome" to refer to negative psychological effects which they attribute to abortion. However, "post-abortion syndrome" is not recognized as an actual syndrome by the mainstream medical community. Post-abortion syndrome (PAS) is not included in the Diagnostic and Statistical Manual of Mental Disorders DSM-IV-TR or in the ICD-10 list of psychiatric conditions. Medical professionals and pro-choice advocates have argued that the effort to popularize the idea of a "post-abortion syndrome" is a tactic used by anti-abortion advocates for political purposes. Some U.S. state legislatures have mandated that patients be told that abortion increases their risk of depression and suicide, despite the scientific evidence contradicting such claims.
