This study examines how news features (framing and the use of exemplars) can help overcome two common barriers (psychological and cognitive) impeding Black American participation in clinical trials. In an online experiment, Black participants ( = 390) viewed social media news posts varying in framing (focus on psychological vs. cognitive barriers) and use of an exemplar (present vs. absent and White vs. Black) and then responded to outcome measures including perceived message effectiveness, message attitudes, and intention to participate in clinical trials. The findings illustrate that including a racially matched (i.e. Black) exemplar improves attitudes toward clinical trial messages. Most notably, featuring a race-matched exemplar increases intention to participate in a trial when the messages discuss psychological barriers. These findings enhance our understanding of how messages can be better designed to increase Black American participation in clinical trials, thereby contributing to reducing health inequities and improving health outcomes.
本研究考察了新闻特写（框架和范例的使用）如何帮助克服阻碍非裔美国人参与临床试验的两个常见障碍（心理和认知）。在一项在线实验中，黑人参试者（n=390）观看了社交媒体新闻帖子，这些帖子在框架（关注心理障碍与认知障碍）和范例使用（有与无、白人与黑人）方面有所不同，然后对包括信息有效性感知、信息态度和参与临床试验的意愿在内的结果指标进行了回应。研究结果表明，纳入一个种族匹配的（即黑人）范例可以改善对临床试验信息的态度。值得注意的是，当信息讨论心理障碍时，展示一个种族匹配的范例会增加参与试验的意愿。这些发现增强了我们对如何更好地设计信息以增加非裔美国人参与临床试验的理解，从而有助于减少健康不平等和改善健康结果。
