Moderation or Moderated mediation?

29 July 2021 3 2K Report

Dear researchers,

I would like to ask about the differences between moderation and moderated mediation analysis? And how to make hypotheses in a moderated mediation relationship?

For example, in a model like this (see attached file), if I am curious about whether corporate image moderates the relationship between customer satisfaction(the moderator) and repurchase intention, do I only do a moderation analysis or a second stage moderated mediation analysis?

If I am going to do moderated mediation, am I testing whether corporate image moderates the mediation effect of customer satisfaction on repurchase intention? I cannot relate to any practical implications of this moderated mediation analysis? Moreover, if making hypotheses, should I say: corporate image moderates the indirect effect of customer experience on repurchase intention through customer satisfaction?

My point is if I am only interested in whether corporate image moderates the relationship between customer satisfaction and repurchase intention, as customer satisfaction is a mediator, do I have to do moderated mediation analysis? what's its advantage compared with merely moderation analysis?

Could anyone recommend some papers that conducted moderated mediation analysis? I want to see how they make hypotheses, and how to interpret the findings. Although I have read the paper by Andrew F. Hayes (2015) "An Index and Test of Linear Moderated Mediation", I still feel not very clear.

Thank you all

Best Regards

@Dear Kara Ma Simple moderation only accounts for enhancing/buffering (interaction effect) the effect of IV on DV (example: the effect of customer satisfaction on repurchase intention is stronger when corporate image is high and vice versa). Whereas, in moderated mediation (when moderation is only at first level i.e., IV >>> Mediator or second level i.e., Mediator >>> DV) we account for conditional indirect effect i.e., varying indirect effect at different levels of the moderator (example: the indirect effect of customer experience on repurchase intention (via customer satisfaction) would be stronger when corporate image is high and vice versa).
