How and When to Use Which Fit Indices? A Practical and Critical Review of the Methodology

Which fit index should I report in structural equation modelling, and when?

Fit indices are too often used as a checklist: whatever clears the cut-off gets reported, whatever does not is quietly dropped. This review examines what χ², CFI, TLI, RMSEA and SRMR actually measure, where they diverge, and how sample size and model complexity move the thresholds. The aim is not another table of cut-offs but clarity about which index answers which question.

Cut-offs are conventions, not laws. Which index you omit says more than the ones you report.
