Chapter 5 More Than One Mediator

As Hayes clarified in the end of the opening section, in this chapter we’ll explore

models with more than one mediator. [We will] focus on two forms of the multiple mediator model defined by whether the mediators are linked together in a causal chain (the serial multiple mediator model) or are merely allowed to correlate bot not causally influence another mediator in the model (the parallel multiple mediator model). [We’ll] also discuss models that blend parallel and serial processes.
