How to measure reflective and formative combined construct in lower order

Post by thossain » Fri Jun 01, 2018 6:52 am

Hello,
I am very new to PLS. My model is a three order reflective model. However, in the lower order, I have a combination of formative and reflective measures. Please see the attached file of the model. I have used repeated indicator approach. Please let me know whether this is ok or not given the combined formative and reflective construct. Also, is there any literature support for this kind of model?

There is not really research addressing mixed lower-order constructs.

A potential problem with the repeated-indicator approach is the direction (i.e., Mode) of the indicators on the higher-order constructs. For formative lower order measures it should be Mode B (i.e., inwards pointing) and for reflective lower order measures it should be Mode A (i.e., outwards pointing).

Similar problems might arise with a two-stage approach in the second stage. Although I would be more comfortable to recommend to use Mode A (outwards pointing) for the mixed indicators in this case, there is no research that has ever shown that it is possible/preferable.

Hello, I have the same case now. Would you please give me some reference to easily understand every step to develop the two stage approach when using formative and reflective indicators in the same second order variable? Thanks in advance.
