Dear friends,
I ran a CFA via with WLSMV estimator, suitable for ordinal variable. However, I am unsure about which indexes to report (standart, scaled or robust). RMSEA value is really high in robust indexes, but its quite low in scaled one. So I am looking for help.
Thanks a lot in advance.

Dear Burak,
Well, the indicators are the same. You have scalar indicators, correctly? But CFA, TLI, SRMR etc are exactly the same.
Regarding RMSEA, there is a long literature questioning it. It perhaps help you: Article An Empirical Evaluation of the Use of Fixed Cutoff Points in...
I hope it helps you.
Best.
Dear professor, thank you for your response.
CFI and TLI are different in scaled, standart and robust indexes. But they are close to each other. SRMR is same as it is already a robust statistic. However, RMSEA is quite high in robust one (.150), but its really low in scaled one (.04). I will read the article you sent.
Best regards.

Thank you for your answers. Actually, my data is dichotomous (0-1). WLSMV is the best option to assess the factor structure. Robust RMSEA is .150, whereas scaled RMSEA is .04. Thats why I got confused, there is a big difference. Is your advice still on for dichotomous data?Regards.
