Abstract

Researchers frequently measure recognition of information in health messages by presenting participants with statements that were or were not in a message and then asking them to identify which were presented and which were not. Recognition scales are then calculated by summing the correct responses to both the true items and foils, or by summing the correct responses to the true items only. We used a sequence of psychometric analyses, including factor analysis and item response theory (IRT) analysis, to evaluate two recognition measures of this type, using data from previously published studies. We found that foils are less associated with true items than true items are with one another, or more practically, that foils are less associated with the underlying dimension of interest. These results provide researchers with insight into how recognition items function, as well as a better analytic approach for use in future studies.

评估健康信息识别量表中的箔片项目。

研究人员经常通过向受试者展示健康信息中存在或不存在的语句，然后让受试者辨别哪些是信息中出现的语句，哪些是信息中没有出现的语句，以此来衡量受试者对健康信息中的信息的识别程度。然后，通过对真实项目和陪衬项目的正确回答求和，或仅对真实项目的正确回答求和，计算出识别量表。我们使用了一系列心理测量分析，包括因子分析和项目反应理论（IRT）分析，利用以前发表的研究数据对两种此类识别量表进行了评估。我们发现，与真实项目之间的关联相比，衬托项目与真实项目之间的关联较小，或者更实际地说，衬托项目与相关维度之间的关联较小。这些结果为研究人员提供了对识别项目如何发挥作用的深入了解，并为今后的研究提供了更好的分析方法。

期刊介绍： Communication Methods and Measures aims to achieve several goals in the field of communication research. Firstly, it aims to bring attention to and showcase developments in both qualitative and quantitative research methodologies to communication scholars. This journal serves as a platform for researchers across the field to discuss and disseminate methodological tools and approaches. Additionally, Communication Methods and Measures seeks to improve research design and analysis practices by offering suggestions for improvement. It aims to introduce new methods of measurement that are valuable to communication scientists or enhance existing methods. The journal encourages submissions that focus on methods for enhancing research design and theory testing, employing both quantitative and qualitative approaches. Furthermore, the journal is open to articles devoted to exploring the epistemological aspects relevant to communication research methodologies. It welcomes well-written manuscripts that demonstrate the use of methods and articles that highlight the advantages of lesser-known or newer methods over those traditionally used in communication. In summary, Communication Methods and Measures strives to advance the field of communication research by showcasing and discussing innovative methodologies, improving research practices, and introducing new measurement methods.
