HTMT Discriminant validity

Post by MaFa » Sat Nov 09, 2019 3:38 pm

Hello colleagues,

In my model, I have three constructs that are very related to each other, so both the correlations are above 0.7 and also HTMT values are 0.9 for them! I do not know what I can do, loadings are ok though. I have removed some items, but still, the issue is there. The CI values for HTMT in bootstrapping is lower than 1 though. Any suggestions would be highly appreciated.
Thanks,
Ana

Given the statistics, discriminant validity at least may be a problem. You need to deal with that. Either by arguing why you think that the constructs are conceptually different despite the opposite finding from the statistics (and why the discriminant validity may not be a problem in your model), or by making changes to your model (e.g., you may model them as a higher-order component or something like this).
Maybe it is also evidence against your theory. Or you need to recollect data and make sure to measure the construct differently.

There are actually no clear and good guidelines in the literature on what to do when discriminant validity fails. It requires some creativity and scientific judgment on your side as you know the problem domain best.
