Structural equation modeling (SEM) goodness of fit indices

Fit statistic	Result	Description	Acceptable range
χ²	1127.71 (df=215), p<0.001	Overall measure of model fit based on discrepancies between the sample and the covariance matrices¹⁰⁶ ¹⁰⁷	Sample size dependent; the result suggests a reasonable fit in light of the study sample size and other goodness of fit measures
Comparative fit index (CFI)	0.96	Comparison of a restricted model to a null model¹⁰⁸	>0.90
Root mean square error of approximation (RMSEA)	0.07	Measure of the discrepancy per degree of freedom¹⁰⁹	<0.05: close fit
			(0.05, 0.08): reasonable fit
			(0.08, 0.10): acceptable fit
Standardized root mean square residual (SRMR)	0.06	Measure of standardized fitted residuals¹⁰⁷ ¹¹⁰	<0.08
