How can I combine data (multiple DVs) for the mediation test on MEMORE (mediation&moderation repeated measures)?

Hello everyone,

Can you help me on how to combine my data since I have multiple dependent variables (I did measure several product preferences), for the mediation test in MEMORE - SPSS macro

I needed to use that macro because my DV is a within-subject variable and measured on 2 different levels (absence of the independent variable). MEMORE gives me the hand of analyzing my DV in an individual way, which is fine but I need to know if my effect is significant even if we combine all the dependent variables.

My knowledge with a within-subject is too limited, I'll appreciate your advice.

Ps. The mediator varies on 2 levels two, but I have a singular mediation.

Thank you for helping me in advance
