Hi all,
I am testing a model with a number of LVs. The results look good in general. The main effects composite reliabilities are greater than the Cronbach's alphas, but the composite reliabilities of the interaction terms vary and some are much lower than the corresponding alphas. Why is this and what can I do? Thanks.

Hi,
I not understand why self * implicit agency result six CR and Cronbach Alpha?
My suggestion, before create interaction terms, evaluation outer model and I see your all construct it's OK. Next, create interaction terms and evaluation inner model (no outer model again). Construct interaction terms have low AVE and CR.
Best Regards,
Hengky
