We investigated the knowledge of pregnant women participating in a maternal serum alphafetoprotein (MSAFP) screening program for the detection of neural tube defects (NTDs) in the fetus. Women participating in the screening program scored higher on two knowledge tests than a comparison group of pregnant women who were not offered screening. However, there were substantial gaps in the knowledge base of women in the program, as measured by one of the tests. Women did not misinterpret a negative test result to mean that the test had identified a potential problem with the fetus; instead, there is a suggestion that they tended to interpret a negative result too positively, as an assurance that the baby was healthy in all respects.
我们调查了参与母体血清甲胎蛋白（MSAFP）筛查项目以检测胎儿神经管缺陷（NTDs）的孕妇的相关知识。参与筛查项目的女性在两项知识测试中的得分高于未接受筛查的孕妇对照组。然而，通过其中一项测试衡量，该项目中女性的知识基础存在很大差距。女性并没有将阴性检测结果误解为意味着检测发现了胎儿存在潜在问题；相反，有迹象表明她们倾向于对阴性结果过于乐观地解读，将其视为胎儿在各方面都健康的保证。
