Model fit indices of the proposed model.

Measures	Fit index	Description	Model index	Recommend level [28]	Model adaptation judgement
Absolute fit measures		Check whether the covariance structure of the model is adequately the same as the covariance matrix of the observed data	2.349	<5	Support
	GFI	Check the overall fit of the model	0.952	>0.90	Support
	RMSEA	Check the mean value of the covariance residual	0.061	<0.08	Support
Incremental fit measures	CFI	Examine whether the model fits the observed data better than the independent model that has no relationships among variables	0.943	>0.90	Support
	NFI	Explore the improvement of the overall fit of the model to the independent model	0.916	>0.80	Support
Parsimonious fit measures	PGFI	Examine the overall parsimony of the model	0.72	>0.50	Support
