One thing is certain, there are many conflicting statistics concerning abortion and its impact on the health of women. In order to evaluate these conflicting claims, Dr. Priscilla Coleman conducted a "meta-analysis" of the literature. She assessed the negative impact abortion has had on the mental health of women, and published her results as "Abortion and mental health: quantitative synthesis and analysis of research published 1995-2009" in the September 2011 British Journal of Psychiatry.
Unfortunately, to some, the truth of the matter doesn't matter. Coleman hasn't made friends in certain places like the American Psychological Association. People at the APA are wedded to a certain frame of reference--and it's not a pro-life one. It is hard to break ingrained pattern of belief, even with careful analysis.
So that we can understand the stringent methods Coleman used, MercatorNet has interviewed her about her methodology. While reading the piece, keep in mind that many women have had their lives turned upside down by the "right" to choose wrongly. They accepted the erroneous pro-abortion information given by respected people and organizations.
It should concern everyone that there are many, many suffering women. Due to their suffering, some will even resort to suicide to stop the pain, leaving even more pain.
All is not lost. There is healing--spiritual and emotional--for women who have had an abortion. (Men, too, are affected by this devastating choice.) For instance, many churches have Stephen Ministries to help the grieving. And there are crisis pregnancy centers, easily found through organizations like CareNet, that help women struggling with unplanned pregnancies.
