A randomised trial was carried out to assess the effect of a Down syndrome screening video on test uptake, knowledge and psychological stress. A total of 2000 women referred for antenatal care were allocated to two equal groups: one to be sent a video to their home, before their hospital booking visit, and a control group. All women also received screening information in the form of a leaflet before booking and from a midwife at booking. The video had no effect on the screening uptake rate: 638/993 (64.2%) and 652/1007 (64.7%) in the video and control groups, respectively. Women were requested to return the video for reuse in other pregnancies and 612 (62%) did so. A subset of 1200 women were selected to be posted at 17-19 weeks' gestation a self-completed questionnaire to assess the psychological endpoints. Knowledge of screening was increased in the video group with a mean score of 7.3 compared with 6.7 in the controls, a statistically significant difference (t=3.24, p=0.0005). There were no significant differences between the groups in specific worries about abnormalities in the baby, and general anxiety. We conclude that a video can increase knowledge without affecting the uptake of the test, or psychological stress.
开展了一项随机试验，以评估唐氏综合征筛查视频对检查接受率、知识掌握情况及心理压力的影响。共有2000名接受产前护理转诊的女性被分为两组，每组人数相等：一组在医院预约就诊前会收到寄到家中的视频，另一组为对照组。所有女性在预约前还会收到一份传单形式的筛查信息，预约时会从助产士那里获取筛查信息。该视频对筛查接受率没有影响：视频组和对照组的接受率分别为638/993（64.2%）和652/1007（64.7%）。女性被要求归还视频以便在其他妊娠中重复使用，612名（62%）女性照做了。选取了1200名女性的子集，在妊娠17 - 19周时向她们邮寄一份自我填写的问卷，以评估心理指标。视频组的筛查知识有所增加，平均得分为7.3分，而对照组为6.7分，差异具有统计学意义（t = 3.24，p = 0.0005）。两组在对胎儿异常的具体担忧和总体焦虑方面没有显著差异。我们得出结论，视频可以增加知识，而不影响检查的接受率或心理压力。
