The informed consent process for research has come under scrutiny, as consent documents are increasingly long and difficult to understand. Innovations are needed to improve comprehension in order to make the consent process truly informed. We report on the development and pilot testing of video clips that could be used during the consent process to better explain research procedures to potential participants. Based on input from researchers and community partners, 15 videos of common research procedures/concepts were produced. The utility of the videos was then tested by embedding them in mock-informed consent documents that were presented via an online electronic consent system designed for delivery via iPad. Three mock consents were developed, each containing five videos. All participants (n = 61) read both a paper version and the video-assisted iPad version of the same mock consent and were randomized to which format they reviewed first. Participants were given a competency quiz that posed specific questions about the information in the consent after reviewing the first consent document to which they were exposed. Most participants (78.7%) preferred the video-assisted format compared to paper (12.9%). Nearly all (96.7%) reported that the videos improved their understanding of the procedures described in the consent document; however, the comprehension of material did not significantly differ by consent format. Results suggest videos may be helpful in providing participants with information about study procedures in a way that is easy to understand. Additional testing of video consents for complex protocols and with subjects of lower literacy is warranted.
知情同意过程的研究已经受到审查,因为同意文件越来越长,难以理解。需要创新来提高理解能力,以使同意过程真正知情。我们报告了开发和试点测试视频剪辑,可以在同意过程中使用,以更好地向潜在参与者解释研究程序。根据研究人员和社区合作伙伴的意见,制作了 15 个常见研究程序/概念的视频。然后通过将它们嵌入到通过专门为通过 iPad 交付而设计的在线电子同意系统呈现的模拟同意文件中,测试了视频的实用性。开发了三个模拟同意书,每个同意书都包含五个视频。所有参与者(n = 61)都阅读了纸质版本和视频辅助 iPad 版本的相同模拟同意书,并随机分配他们首先查看哪种格式。参与者接受了一项能力测验,在查看他们首先接触到的第一份同意书后,就同意书中的信息提出了具体问题。与纸质同意书(12.9%)相比,大多数参与者(78.7%)更喜欢视频辅助格式。几乎所有人(96.7%)都表示,视频提高了他们对同意文件中描述的程序的理解;然而,同意格式对材料的理解没有显著差异。结果表明,视频可能有助于以易于理解的方式向参与者提供有关研究程序的信息。需要进一步测试用于复杂方案和低识字率受试者的视频同意书。
