Abstract

Public participation in precision medicine (PM) research is essential to achieving effective health care but has been impeded by a lack of awareness and basic knowledge. There is a critical need for educational materials that can clearly explain PM to foster involvement. This randomized controlled trial with a posttest-only control group design aims to assess the effects of educational messages delivered through animations relative to live-action videos and leaflets on intentions of involvement in PM research. Knowledge as the moderator and four mediators (engagement, vividness, trustworthiness, and cognitive value) of the intended effects were also evaluated. A total of 326 U.S. adults were sampled from Amazon Mechanical Turk. Among participants with less knowledge about PM, animations produced stronger information-seeking intentions and willingness to participate than leaflets. The effects of three message modalities were not significantly different among average and highly knowledgeable participants. Engagement and vividness mediated the effects of animations relative to two other message modalities. Trustworthiness and cognitive value mediated the effects of animations relative to live-action videos. Overall, animations can be an effective communication strategy to motivate involvement in PM but its effectiveness could decline as knowledge increases. The explanations and implications of the findings were discussed.

动画和多媒体信息对公众参与精准医疗的影响：评估调节和中介作用

公众参与精准医学（PM）研究对实现有效的医疗保健至关重要，但由于缺乏认识和基本知识，公众参与一直受到阻碍。目前亟需能清楚解释精准医学的教育材料，以促进公众参与。这项随机对照试验采用了仅事后对照组的设计，旨在评估相对于真人视频和传单而言，通过动画传递的教育信息对参与预防疟疾研究的意愿的影响。同时还评估了知识作为调节因素以及预期效果的四个中介因素（参与度、生动性、可信度和认知价值）。亚马逊 Mechanical Turk 共抽取了 326 名美国成年人。在对 PM 了解较少的参与者中，动画比传单产生了更强的信息寻求意愿和参与意愿。在知识水平一般和知识水平较高的参与者中，三种信息模式的效果没有明显差异。相对于其他两种信息模式，动画的参与性和生动性对其效果起到了中介作用。相对于真人视频，动画的可信度和认知价值对动画的效果起到了中介作用。总之，动画可以作为一种有效的传播策略来激励人们参与项目管理，但其有效性可能会随着知识的增加而下降。会上还讨论了研究结果的解释和影响。
