Dear all
I have three second order constructs and two single order constructs. These are reflective constructs. And I have one more formative constuct.
To purify(reliability and validity check) the scale, I did CFA them with AMOS using global fit index such as GFI, CFI, and RMSEA, TLI.
And then to investigate structural model with, PLS I checked the relibility and validity with PLS again. Is it unnessary? I did this because I have many 2nd order constructs, it woud be difficults to CFA all model in PLS altogther.
Any comments are welcomed.
