(1) To create a short motion graphic video to debias women, using evidence from cognitive psychology, of 2 common myths about safety of intrauterine devices (IUDs) and implants in Jamaica; and (2) to conduct a pilot study to evaluate video effectiveness.
We conducted a series of 3 focus group discussions among target users to inform the development process of the script, story, character, and look of the intervention video. We randomized young, female nonusers of long-acting contraception at risk of pregnancy at a public clinic in Kingston in 2018-2019 to watch either the intervention (n = 113) or control video (n = 112). We used logistical regression to evaluate perceptions of method safety, naturalness, and uptake after 3 months of follow up.
Almost all (n = 220; 97.8%) participants completed the 3-month interview. More women in the intervention arm perceived IUDs to be safe (59.1%) compared to the control arm (43.6%; p = 0.02). Perceived implant safety increased from enrollment to follow up in the intervention and control arms (10.9 and 2.7 percentage-point increases, respectively); however, the difference between arms at follow up was not statistically significant (p = 0.57). This appeared to be due to arm imbalances at enrollment. Study arms did not differ at follow up in perceived IUD naturalness (p = 0.36) or implant naturalness (p = 0.68).
Findings from a pilot study of a video intervention suggest that using debiasing strategies from cognitive psychology has the potential to address misconceptions about contraceptive safety. A larger trial with adequate power is warranted.
Evidence from a pilot randomized controlled trial suggested that use of debiasing strategies from cognitive psychology could be effective in correcting women's misconceptions about contraception safety and thus show promise for the design of future contraceptive promotion videos to increase uptake.
（1）使用来自认知心理学的证据，为牙买加的女性创建一个关于宫内节育器（IUD）和植入物安全性的 2 个常见神话的短视频，以消除这些偏见；（2）进行一项试点研究，以评估视频的效果。
我们在金斯敦的一家公共诊所对有怀孕风险的年轻、未使用过长效避孕措施的女性进行了一系列 3 次焦点小组讨论，以告知干预视频脚本、故事情节、角色和外观的开发过程。我们在 2018 年至 2019 年期间，将 201 名年轻、未使用过长效避孕措施的、有怀孕风险的女性随机分为干预组（n=113）和对照组（n=112），让她们观看干预视频或对照视频。我们使用逻辑回归评估了 3 个月随访后对方法安全性、自然性和采用率的看法。
几乎所有（n=220；97.8%）参与者都完成了 3 个月的访谈。与对照组（43.6%；p=0.02）相比，干预组中更多的女性认为 IUD 是安全的（59.1%）。干预组和对照组的植入物安全性感知从入组到随访都有所增加（分别增加了 10.9 和 2.7 个百分点）；然而，随访时两组之间的差异没有统计学意义（p=0.57）。这似乎是由于入组时手臂不平衡造成的。随访时，研究组在 IUD 自然性（p=0.36）或植入物自然性（p=0.68）方面没有差异。
一项短视频干预试验的初步结果表明，使用认知心理学中的去偏策略有可能纠正关于避孕安全性的误解。需要进行一项具有足够效力的更大规模试验。
一项小型随机对照试验的证据表明，使用认知心理学中的去偏策略可能会有效纠正女性对避孕安全性的误解，从而为设计未来的避孕推广视频以提高采用率提供了希望。
