When an item is loading highly on two constructs, it impacts the discriminant validity and inflates SRMR.
Following, compiled from Meta AI, may be helpful for you.
If your SRMR = 0.085, please see the following :
0.085 vs 0.08 is a 0.005 difference. Most reviewers won’t reject based on that alone. SRMR is sensitive to sample size and model complexity.
For PLS-SEM, primary evaluation = R², Q², path significance, effect sizes. SRMR is “nice to have” but not mandatory. If your journal/advisor uses Henseler’s 2014 guidelines, SRMR is secondary.
If R² > 0.25, Q² > 0, VIF < 5, rho_c > 0.7, and HTMT < 0.90, you can defend the model. SRMR alone doesn’t kill your study.
Hu & Bentler’s 0.08 cutoff was made for CB-SEM. For PLS-SEM, Hair et al. 2022 say SRMR is only an _approximate_ fit measure. PLS focuses on prediction, not fit. Many reviewers don’t even require SRMR in PLS.
