Model fit indices of the proposed model.

Measures	Fit index	Description	Range	Recommend level	Model index	Source
Absolute fit measures	X^2/df	Check whether the covariance structure of the model is adequately the same as the covariance matrix of the observed data	>0	1-2	1.786	[95]
	GFI	Check overall fit of the model; percent of the covariance of the observed data can be explained by the covariance of the model	0-1	>0.95	0.971	[96]
	RMSEA	Check the mean value of the covariance residual	>0	<0.05	0.034	[97]
Incremental fit measures	CFI	Examine whether the model fits the observed data better than the independent model that has no relationships among variables	0-1	>0.9	0.939	[98]
	NFI	Explore the improvement of the overall fit of the model to independent model	0-1	>0.8	0.889	[99]
Parsimonious fit measures	PGFI	Examine the overall parsimony of the model	0-1	>0.7	0.895	[100]
