Decisional conflict and regret: shared decision-making about pregnancy affected by β-thalassemia major in Southeast of Iran.

To study the effect of shared decision-making (SDM) on decisional conflict (DC) scores immediately after consultation and to assess the decisional regret (DR) scores in the first 3 months following women's decision regarding termination of pregnancy. This quasi-experimental study was conducted during August 3rd-February 20th, 2016. We included 80 women whose fetuses were diagnosed with β-thalassemia major (β-TM) through chorionic villi sampling and were referred to the only prenatal diagnosis center at Ali-Asghar Hospital, Zahedan, Iran. While the control group went through the routine procedures, the intervention group received a 90-min counseling session based on SDM. The demographic characteristics form and DC scale were filled out immediately after the consultation session. After 3 months, the women were contacted via telephone call to collect data on their level of DR. The mean DC score was significantly (P = < 0.0025) lower in the intervention group (8.47 ± 4.63) compared with the control group (44.10 ± 14.5). Moreover, the mean score of DR was significantly (P = 0.004) lower in the intervention group (9.37 ± 15.44) compared with the control group (24.37 ± 23.42). SDM consultation can help women experience significantly lower levels of DC and DR.
