人们对少数群体对强调癌症种族差异的公共信息有何反应知之甚少。这项双盲随机研究将模拟新闻文章中呈现的相同结肠癌 (CRC) 信息的四个版本的情绪和行为反应与非裔美国成年人社区样本 (n = 300) 进行了比较。参与者阅读了四篇文章中的一篇，这些文章对特定种族的 CRC 死亡率数据的框架和解释各不相同，强调影响（CRC 对非裔美国人来说是一个重要问题）、差异的两个维度（黑人的情况比白人差，黑人的情况有所改善，但低于白人）或进步（黑人随着时间的推移而改善）。与其他组相比，接触差异文章的参与者对信息有更多的负面情绪反应，并且不太愿意接受 CRC 筛查（均 P < 0.001）。相比之下，进展文章引起了更积极的情绪反应，参与者更有可能希望接受筛查。此外，负面情绪反应似乎介导了消息类型对想要进行结直肠癌筛查的个体的影响。总体而言，这些结果表明，媒体报道差异研究的方式可以影响公众的态度和意图，有关进展的报道对意图产生更积极的影响。这对于那些对医疗高度不信任的人来说尤其重要，他们最不可能使用医疗保健系统，因此成为健康促进广告的主要目标。 （癌症流行病学生物标志物，2008 年以前；17(11):2946-53）
Little is known about how minority groups react to public information that highlights racial disparities in cancer. This double-blind randomized study compared emotional and behavioral reactions to four versions of the same colon cancer (CRC) information presented in mock news articles to a community sample of African-American adults (n = 300). Participants read one of four articles that varied in their framing and interpretation of race-specific CRC mortality data, emphasizing impact (CRC is an important problem for African-Americans), two dimensions of disparity (Blacks are doing worse than Whites and Blacks are improving, but less than Whites), or progress (Blacks are improving over time). Participants exposed to disparity articles reported more negative emotional reactions to the information and were less likely to want to be screened for CRC than those in other groups (both P < 0.001). In contrast, progress articles elicited more positive emotional reactions and participants were more likely to want to be screened. Moreover, negative emotional reaction seemed to mediate the influence of message type on individuals wanting to be screened for CRC. Overall, these results suggest that the way in which disparity research is reported in the medium can influence public attitudes and intentions, with reports about progress yielding a more positive effect on intention. This seems especially important among those with high levels of medical mistrust who are least likely to use the health care system and are thus the primary target of health promotion advertising.
