I'm doing a PROCESS Model 4 mediation analysis, where:
X = Persuasion Knowledge (continuous)
M1 = Brand Attitude (continuous)
M2 = Brand Awareness, which consists of aided brand recall (dichotomous) and unaided brand recall (dichotomous)
I tried putting it into PROCESS with three mediating variables, but I get the error that the mediators are dichotomous.
What can I do? I cannot find any literature that merges aided recall and unaided recall in one variable... should I just do that? Or is there a way to use 3 mediators in PROCESS from which two are dichotomous variables?
