Query regarding convergent validity of formative model

[Tawseef ur Rehman]

Respected members hope you all are fine.

Hair, et. Al 2017 has mentioned checking convergent validity as ist step of validating the formative model in pls sem. But researchers have not mentioned this in their papers. They have directly jumped to checking indicator collinearity and relevance and significance of weights.

My query is, is it a necessary step or we can skip this?

Thanks in anticipation.

Dear Tawseef, the Convergent Validity of formative constructs is
assessed through Redundancy Analysis.
A redundancy analysis is a procedure, in which each formatively
specified construct is correlated with an alternative measure of it
(Chin, 1998). When running a redundancy analysis, researchers can opt
for a global single-item, or for a reflectively specified multi-item
measure, as the criterion variable..

Actually the model is reflective-formative, when validiating formative model I didn't see this step in research papers they have skipped this redundancy analysis.

Dear TuR

You are correct. Though Redundancy analysis shd be a compulsory part of reporting any formative construct but we people do not report it. 

One reason for the same is that data for the global item must be collected while collecting the rest of the data.

Many scholars do not have a proper understanding of the formative and reflective construct at the time of the start of their work, so by the time they come to know about it, data collection for the global item is not possible.

But if you've collected data for the global item, you must report it.

Best wishes

Unfortunately, I am also among one who came to know these concepts after data collection. Thank you sir.

Dear Karan

Yes, Redundancy analysis shd always be performed on any and every formative construct, may it be lower order or higher order.

Best wishes

Hi Prof. Neeraj.

Do we need to do redundancy analysis for a second order formative construct? Can u provide the reference for the same, incase it is not desirable.
