I am running a PLS-PM to evaluate Satisfaction "S".

I have defined a latent variable LV "D" and I concern how to define the manifest variables(MV).

I have:

• 3 variables regarding satisfaction with "D", expressed on 7-likert scale
• 1 variable regarding how many x you consume
• 1 variable regarding how much you spend to buy x

My doubt:

I expect the satisfaction MVs to be positive correlated with LV and the last two MVs to be negative correlated. I have seen someone trasforming MVs into negativeMVs to have unidimensionality condition respected, but I would like to avoid this solution becouse it conceptually does not make much sense.

Thanks a lot for the attenction, any help will be highly appreciated.
