We sought to test whether participation in an online group including IUD users influenced IUD-related knowledge, attitudes, and behavior among IUD non-users, as a proof-of-concept evaluation of information dissemination for less commonly used or novel contraceptives.
We conducted a blinded, randomized controlled trial on the effect of online communication with IUD users within an online program called Birth Control Connect. Participants were women age 18-45 living in the United States who had never used an IUD. We invited participants randomized to the intervention to join two-week, nine-member discussion groups including four satisfied IUD users and five IUD non-users; we invited control participants to groups including nine IUD non-users. We performed chi-squared tests on IUD knowledge, information-seeking, informational support and use in immediate post-surveys, and t-tests comparing change in IUD attitudes and frequency of logins to discussion groups.
We invited 488 IUD non-users and enrolled them into 70 groups between October 2015 and April 2016. We found increased positive attitudes towards the IUD in the intervention arm (0.65-point increase between pre- and post-surveys, versus 0.05 mean change for control arm, p = 0.03 for hormonal IUD, with a trend in the same direction for the non-hormonal IUD). Informational support also increased, with 70.3% of intervention arm participants self-reporting that they gained a better idea of what the IUD would be like, compared to 51.3% in control arm (p < 0.01). Of intervention participants, 63.3% versus 51.3% of control participants reported gaining new information from their group (p = 0.03). There were no differences in correct responses to knowledge items or information-seeking between groups.
Online exposure to IUD users increased positive attitudes toward the IUD and informational support for decision-making about the IUD among non-users.
Online spaces provide a promising environment for the exchange of accurate, useful contraceptive information based on real user experiences. Interventions aiming to harness social communication through structured online conversations (e.g., on existing social media platforms) about user experiences with lesser-known contraceptive methods such as the IUD may be worthwhile.
我们旨在测试在避孕节育在线交流项目中，参与宫内节育器使用者群组是否会影响宫内节育器非使用者对宫内节育器的相关知识、态度和行为，以作为对较不常用或新型避孕药具的信息传播进行概念验证评估。
我们在名为“避孕节育连接”的在线项目中进行了一项关于在线与宫内节育器使用者交流对非使用者影响的双盲、随机对照试验。参与者为年龄在 18-45 岁之间、居住在美国且从未使用过宫内节育器的女性。我们邀请随机分配到干预组的参与者加入为期两周、有九名成员的讨论组，其中包括四名满意的宫内节育器使用者和五名宫内节育器非使用者；我们邀请对照组的参与者加入包括九名宫内节育器非使用者的小组。我们在即时调查后进行了卡方检验，以评估宫内节育器知识、信息寻求、信息支持和使用情况，并进行 t 检验比较宫内节育器态度的变化和登录讨论组的频率。
我们邀请了 488 名宫内节育器非使用者，并在 2015 年 10 月至 2016 年 4 月期间将他们纳入 70 个小组。我们发现干预组对宫内节育器的态度更加积极（干预组在预调查和后调查之间增加了 0.65 分，而对照组平均变化为 0.05 分，p=0.03 用于激素宫内节育器，而非激素宫内节育器也有类似的趋势）。信息支持也有所增加，70.3%的干预组参与者表示他们对宫内节育器的情况有了更好的了解，而对照组为 51.3%（p<0.01）。与对照组相比，干预组中有 63.3%的参与者表示从他们的小组中获得了新信息，而对照组为 51.3%（p=0.03）。两组在知识项目的正确回答或信息寻求方面没有差异。
在线接触宫内节育器使用者增加了非使用者对宫内节育器的积极态度和决策支持信息。
在线空间为基于真实用户体验的准确、有用的避孕信息交流提供了有前景的环境。旨在利用通过关于不太知名的避孕方法（如宫内节育器）的用户体验进行结构化在线对话（例如，在现有的社交媒体平台上）进行社交交流的干预措施可能是值得的。
