In a study at the Beth Israel Medical Center in Boston, Alice Domar and her team randomly assigned 184 women who had been trying to get pregnant for 1-2 years into 3 groups: a 10-session cognitive-behavioral group, a standard support group, or a routine care control group. They were followed for 1 year to see how many became pregnant. Sixty-four women discontinued participation in the study. A total of 47 women in the cognitive-behavioral group became pregnant, and 48 in the support group, as opposed to only 25 in the control group. Because these are statistically significant differences, the study concludes that group psychological interventions appear to lead to increased pregnancy rates in infertile women.
