本文介绍了疾病控制和预防中心明确的沟通指数（指数），一个工具，强调主要受众的需求，并提供了一套基于证据的标准，以开发和评估公共传播产品的不同受众。根据科学文献，该指数由四个开放式介绍性问题和20个影响信息清晰度和受众理解的评分项目组成。一个研究小组进行了一次在线调查，以测试该指数的有效性。受访者回答了10个关于原始健康材料或使用该指数重新设计的健康材料的问题。在10个问题中，有9个问题的评分高于原始材料。无论教育水平如何，受访者对修订后的材料的评价都比原来的更好。结果表明，索引的表现符合预期，使受众更有可能正确识别预期的主要信息，并理解材料中的单词和数字。研究结果也支持了一个普遍的观点，即观众对设计清晰的材料更积极。该指数表明，循证评分规则可以评估和提高卫生材料的清晰度。
This article presents the Centers for Disease Control and Prevention Clear Communication Index (the Index), a tool that emphasizes the primary audience's needs and provides a set of evidence-based criteria to develop and assess public communication products for diverse audiences. The Index consists of four open-ended introductory questions and 20 scored items that affect information clarity and audience comprehension, according to the scientific literature. A research team fielded an online survey to test the Index's validity. Respondents answered 10 questions about either an original health material or one redesigned with the Index. For 9 out of 10 questions, the materials revised using the Index were rated higher than the original materials. Regardless of education level, respondents rated the revised materials more favorably than the original ones. The results indicate that the Index performed as intended and made it more likely that audiences could correctly identify the intended main message and understand the words and numbers in the materials. The results also support the widely held view that audiences are more positive about clearly designed materials. The Index shows that an evidence-based scoring rubric can assess and improve the clarity of health materials.
