HCM: Typ Reflective-Formative and Formativ-Formative

Post by Boddien » Fri Sep 15, 2017 6:04 pm

Dear forum,

I have a SEM with 3 HCMs: 2 HCMS of formative-formative type and 1 HCM of reflective-formative type.

My questions:
1. Regarding the formative-formative type: Do I have to use a global single item not only for the HOC but also for each of the LOCs for validity purposes?
2. Do the LOCs of the reflective-formative type have to have each the same number of indicators?
3. Where can I find more detailed information regarding the assessment of the reflective-formative type?
3. As the model is non-recursive, I would like to take the score of the PLS estimates and then do a Two-Stage Least Squares (2SLS) regression analysis. What kind of software can do the 2SLS part? Or is there now a possibility to model that in smartpls?
Thank you very much in advance.

Best regards,
Simone

@1: no. you either use the repeated indicator approach or the two stage approach.

@2: should have.

@3: see above ref.
