To evaluate the effects of an information film on making an informed choice regarding Down syndrome screening, and women's knowledge and experiences of information.
Randomized controlled trial including 184 women in the intervention group and 206 controls recruited from maternity units in Stockholm, Sweden. The intervention was an information film presented as a complement to written and verbal information. Data were collected via a questionnaire in gestational week 27. Three different measures were combined to measure informed choice: attitudes towards Down syndrome screening, knowledge about Down syndrome and Down syndrome screening, and uptake of CUB (combined ultrasound and biochemical screening).
In the intervention group 71.5% made an informed choice versus 62.4% in the control group. Women in the intervention group had significantly increased knowledge, and to a greater extent than the control group, experienced the information as being sufficient, comprehensible, and correct.
An information film tended to increase the number of women who made an informed choice about Down syndrome screening. Participants were more satisfied with the information received.
Access to correct, nondirective, and sufficient information is essential when making a choice about prenatal diagnostics. It is essential with equivalent information to all women.
评估信息影片对唐氏综合征筛查知情选择的影响，以及女性对信息的了解和经验。
这是一项随机对照试验，研究对象为来自瑞典斯德哥尔摩妇产医院的 184 名干预组妇女和 206 名对照组妇女。干预措施是提供一部信息影片，作为书面和口头信息的补充。数据在妊娠 27 周时通过问卷调查收集。通过三种不同的措施来衡量知情选择：对唐氏综合征筛查的态度、对唐氏综合征和唐氏综合征筛查的了解以及 CUB（联合超声和生化筛查）的采用。
干预组中 71.5%的妇女做出了知情选择，而对照组中这一比例为 62.4%。干预组的妇女知识显著增加，而且比对照组更能感受到信息的充分、易懂和正确。
信息影片倾向于增加对唐氏综合征筛查做出知情选择的妇女数量。参与者对所获得的信息更满意。
在进行产前诊断选择时，获取正确、非导向性和充分的信息至关重要。这对于所有女性都是必要的。
