媒体显着性——议程设置研究中的关键自变量——传统上被解释为一个单一的结构。尽管如此，学者们仍然使用许多不同的概念和经验指标来定义和衡量它。为了解决研究中的这一局限性，本研究引入了媒体显着性的概念模型，表明它是一个由三个核心要素组成的多维结构：注意力、突出性和效价。此外，还以《纽约时报》对 2000 年总统选举期间 8 个主要政治问题的新闻报道作为案例研究，对模型进行了探索性因素分析。数据显示，媒体显着性有两个维度：可见性和效价。基于因子分析，创建了 2 个指数来衡量该结构，以供将来的调查使用。
Media salience—the key independent variable in agenda-setting research—has traditionally been explicated as a singular construct. Nevertheless, scholars have defined and measured it using a number of different conceptualizations and empirical indicators. To address this limitation in research, this study introduced a conceptual model of media salience, suggesting it is a multidimensional construct consisting of 3 core elements: attention, prominence, and valence. Furthermore, the model was tested through an exploratory factor analysis of The New York Times news coverage of 8 major political issues during the 2000 presidential election as a case study. The data revealed that 2 dimensions of media salience emerge: visibility and valence. Based on the factor analysis, 2 indices are created to measure the construct, which are intended for use in future investigations.
