URGENT: Discriminant validity of lower order constrcuts

Post by hurdemirbilek » Mon Jun 22, 2020 5:07 pm

Hi,

My model is reflective-reflective.
Do I have to expect discriminant validity between lower order constructs?
Ex/ HOC: A
LOC: A1,A2,A3,A4

In Fornell-Larcker matrix the correlation between A1 and A3 exceeds the square root of A1.
And also HTMT for A1 and A3 is 1.011.

What am I supposed to do? Ignoring the discriminant validity between lower order constructs?

Thanks

Thanks for your reply.
But I have already read that journal.

It is stated that the lower-order components must exhibit discriminant validity among each other and to all other constructs in the model—except for their own higher-order component of which they are a part of.


My question is I dont have discriminant validity between lower order constructs.
Is that problem ignorable? Because as far as I have searched in the forum, I read your replies about that problem and saying that:
It is not unusual to have discriminant validity between lower order constructs (the subject:HTMT for second order reflective construct) and
One would not necessarily expect discriminant validity between lower order constructs (the subject:second order construct need HTMT and/or Fornell-Larcker criterion or not?).

This is my question too, can anyone help, please?
Can we ignore the high correlation (about 0.85) between two lower-level constructs (which form a second-order construct)?
hurdemirbilek: have you found any answer you can share please?
Thanks!
