Abstract

Abstract Recent analytical work reveals the need to assess mediated interactions (independent variable-by-mediator multiplicative terms) in mediation models to ensure the proper reporting of indirect effects. Besides their analytical value, mediated interactions can aid theory development. This study adds a theoretical support structure to this emergent analytical imperative and provides a theory-driven decision tree for incorporating mediated interactions into communication models. More broadly, mediated interactions are used as a basis to encourage the field to move beyond a “one variable, one role” approach to model building. Monte Carlo simulations reflecting common communication research practices were constructed and 1,920,000 datasets were analyzed to reveal the relative upsides and minimal risk incurred from assessing mediated interactions. In addition, the analyses elucidate the downsides incurred from not exploring these relationships when they are present in a population. The implications of these findings for future research and theory development are explored.

从“一个变量，一个角色”的思维模式中拉出领域:最大化传播中介模型中交互术语的理论价值

最近的分析工作表明，需要评估中介模型中的中介相互作用(独立变量对中介的乘法项)，以确保正确报告间接影响。除了它们的分析价值外，中介相互作用还可以帮助理论发展。本研究为这一紧迫的分析需求提供了理论支持结构，并为将中介交互纳入沟通模型提供了理论驱动的决策树。更广泛地说，中介互动被用作鼓励该领域超越“一个变量，一个角色”的模型构建方法的基础。构建了蒙特卡罗模拟，反映了常见的通信研究实践，并分析了1,920,000个数据集，以揭示评估中介交互的相对优势和最小风险。此外，分析还阐明了在种群中存在这些关系时不探索它们所带来的不利影响。这些发现对未来的研究和理论发展的意义进行了探讨。
