Assessment of model suitability.

Model Fit Index	SRMR	CFI	TLI	RMSEA	NFI	GFI	${\mathit{\chi }}^2/\mathit{d}\mathit{f}$
Evaluation Criteria	<0.08	>0.90	>0.90	<0.08	>0.90	>0.90	<3.0
Model Index	0.077	0.945	0.937	0.064	0.912	0.902	2.489

Note: SRMR = standardized root mean square residual; CFI = comparative fit index; TLI = Tucker–Lewis index; RMSEA = root-mean-squared error of the approximation; NFI = normed fit index; GFI = goodness of fit Index; ${\chi }^2/df$ = chi-squared freedom ratio.
