Abstract
In the past decade, moderated mediation analysis has been extensively and increasingly employed in social and behavioral sciences. With its widespread use, it is particularly important to ensure the moderated mediation analysis will not bring spurious results. Spurious effects have been studied in both mediation and moderation analysis, but this issue remains unexplored in moderated mediation analysis. To fill this gap, we examined the conditions under which a spurious moderated mediation effect in a dual stage moderated mediation model might occur. Specifically, with a hypothetical example and three theorems, we illustrated how the index of moderated moderated mediation may conclude a moderated mediation effect which does not actually exist. As a remedy to rule out the spurious results, we proposed two methods which are simple and easy to implement. Based on the simulation results, we offer researchers some practical guidelines to apply the methods in empirical research.
期刊介绍：
Structural Equation Modeling: A Multidisciplinary Journal publishes refereed scholarly work from all academic disciplines interested in structural equation modeling. These disciplines include, but are not limited to, psychology, medicine, sociology, education, political science, economics, management, and business/marketing. Theoretical articles address new developments; applied articles deal with innovative structural equation modeling applications; the Teacher’s Corner provides instructional modules on aspects of structural equation modeling; book and software reviews examine new modeling information and techniques; and advertising alerts readers to new products. Comments on technical or substantive issues addressed in articles or reviews published in the journal are encouraged; comments are reviewed, and authors of the original works are invited to respond.
