In many studies these two terms have been used interchangeably, although they are different. My understanding is that in moderated-mediation, moderation occurs in the first place that is then mediated, while in mediated-moderation, mediation is contingent on a 3rd variable (moderator). Can anyone shed light on this?
Moderated mediation, also known as conditional indirect effects, occurs when the treatment effect of an independent variable A on an outcome variable C via a mediator variable B differs depending on levels of a moderator variable D. Specifically, either the effect of A on the B, and/or the effect of B on C depends on the level of D.
Moderated mediation relies on the same underlying models (specified above) as mediated moderation. The main difference between the two processes is whether there is overall moderation of the treatment effect of A on the outcome variable C. If there is, then there is mediated moderation. If there is no overall moderation of A on C, then there is moderated mediation.
This article can help you in understanding the "Moderated-Mediated and Mediated-Moderated". The Article name is "When Moderation Is Mediated and Mediation Is Moderated".
