Pregnant women impacted by cytomegalovirus (CMV) make clinical decisions despite uncertain outcomes. Intolerance of uncertainty score (IUS) is a validated measure of tendency for individuals to find unacceptable that a negative event might occur. We investigated patient perceptions of CMV infection during pregnancy and correlated IUS and knowledge with decision-making. Electronic questionnaire was sent to women from July to August 2017. The questionnaire evaluated knowledge of CMV, IUS, and responses regarding management to three clinical scenarios with escalating risk of CMV including choices for no further testing, ultrasound, amniocentesis, or abortion. For each scenario, logistic regression was used to model IUS on responses. A total of 815 women were included. The majority of participants was white (63.1%) and 42% had a postgraduate degree. Over 70% reported that they had not previously heard of CMV. In the scenario with only CMV exposure, participants with increasing IUS were more likely to choose abortion (odds ratio [OR] = 1.04; 95% confidence interval [CI]: 1.01, 1.06) and no further testing (OR = 0.97; 95% CI: 0.95, 0.99). In the scenario with mild ultrasound findings in setting of CMV exposure, increasing IUS was associated with higher odds of choosing no further testing (OR = 0.97; 95% CI, 0.94, 0.99). No significant association was observed between IUS and responses in the scenario with severe ultrasound abnormalities in setting of CMV exposure. The majority of patients had no knowledge of CMV. Higher IUS was associated more intervention in low severity scenarios, but in severe scenarios, IUS was not associated with participants' choices.
