考虑态度在产前检测选择中的作用的研究通常集中在对接受检测的态度和实际检测行为之间的关系上。相比之下，这项研究的重点是测试行为和对行为目标的态度之间的关系（在这种情况下，患有唐氏综合症（DS）的人和患有DS的婴儿）。一项对197名孕妇的横断面前瞻性调查测量了对产前检测目标的态度，沿着使用筛查和诊断检测的意图，以及终止受影响的妊娠。通过患者记录确定筛选摄取。虽然对DS的态度和有一个婴儿与DS显着相关的筛查吸收和测试和终止的意图，不利的态度比有利的预测这些结果。例如，在对DS患者持“最有利”态度的四分之一女性中，67%的人使用筛查，尽管只有8%的人表示他们会终止受影响的妊娠。定性数据表明，并不是所有的妇女认为个人对DS的态度是相关的筛选决定。这一发现对目前在产前检测背景下理解和衡量知情选择的方式具有影响。
Research considering the role of attitudes in prenatal testing choices has commonly focused on the relationship between the attitude towards undergoing testing and actual testing behaviour. In contrast, this study focused on the relationship between testing behaviour and attitudes towards the targets of the behaviour (in this case people with Down syndrome (DS) and having a baby with DS). A cross-sectional, prospective survey of 197 pregnant women measured attitudes towards the targets of prenatal testing along with intentions to use screening and diagnostic testing, and the termination of an affected pregnancy. Screening uptake was established via patient records. Although attitudes towards DS and having a baby with DS were significantly associated with screening uptake and testing and termination intentions, unfavourable attitudes were better than favourable ones at predicting these outcomes. For example, in the quartile of women with the 'most favourable' attitude towards people with DS 67% used screening although only 8% said they would terminate an affected pregnancy. Qualitative data suggested that not all women considered personal attitudes towards DS to be relevant to their screening decisions. This finding has implications for the way in which informed choice is currently understood and measured in the prenatal testing context.
