Introduction: Several factors influence women’s decision to take First Trimester Screening (FTS) tests. These factors are associated with the ambivalence of women toward undergoing screening tests. 
Objective: This study aimed to investigate the effect of Shared Decision-Making (SDM) about undergoing FTS on Decisional Conflict (DC) immediately after consultation and uptake of FTS.
Materials and Methods: This quasi-experimental study was conducted on 200 pregnant women (100 women in the intervention and 100 in the control groups) referred to health centers for prenatal care in 2019. They were selected by the block randomization sampling method. The control group received the routine care and the intervention group, in addition to routine care, attended a 90-min long consultation session based on SDM. The women were contacted via phone at 14 weeks of pregnancy to collect data on their undertaking prenatal screening tests. The demographic characteristics form and O’Conner’s decisional conflict scale were filled out immediately after the consultation session for the intervention group. The obtained data were analyzed by the Chi-square, Fisher exact-test, Mann-Whitney U, and linear regression tests. The P value less than 0.05 was considered statistically significant. 
Results: There was no significant difference between the two groups regarding women’s demographic characteristics, except for education level, job, and insurance coverage. The Mean±SD DC score was significantly lower in the intervention group (7.35±8.55) compared to the control group (27.32±13.81) (95%CI; 16.80-24.19, P=0.001). In addition, there was a significant difference between the two groups in terms of undergoing the offered FTS (P=0.04). The DC scores ≥25 were associated with a decreased chance of undergoing FTS (P=0.02). Women were less likely to undergo FTS when they were self-employed (OR=0.15, 95%CI; 0.03-0.71, P=0.01).
Conclusion: The SDM consultation can help women experience significantly lower levels of DC. Furthermore, factors such as self-employment can prevent women from undergoing FTS despite lower levels of DC.
