Use moderators as stratified variables in sampling for following research Moderator effects might suggest potential Specifically, whereas first-generation research seeks to identify whether there is an association between a specific intervention and a desired outcome, second Abstract Mediation and moderation are two theories for refining and understanding a causal relationship. Thus, the goal Mediation Models Including More Than One Mediator: The Parallel and Serial Multiple Mediator Model Some research questions require inclusion of more than one mediator into the conceptual model. Mediators describe the psychological process that occurs to create the relationship, and as such are always dynamic Abstract Mediation analysis is a statistical approach that can provide insights regarding the inter-mediary processes by which an intervention or exposure afects a given outcome.
