Table 2 Model fit indices

Fit statistic	Index	Criterion for fit	Result—interpretation
Likelihood ratio	Chi squared test (χms²)	p > 0.05	χ² (df 41) = 107.29, p < 0.001—misfit
Likelihood ratio	Normed Chi square [χ²/df]	χ²/df < 2	2.6—misfit
Population error	Root mean squared error of approximation (RMSEA)-(90% CI)	RMSEA ≤ 0.06	0.060 (0.026:0.080)—slight misfit
Information criteria	Akaike’s information criterion (AIC)	The smaller, the better	12,214.5—best fit
Information criteria	Bayesian information criterion (BIC)	The smaller, the better	12,351.5—best fit
Baseline comparison	Comparative Fit Index (CFI)	CFI ≥ 0.90	0.904—good fit
Baseline comparison	Tucker-Lewis Index (LFI)	LFI ≥ 0.90	0.871—a slight misfit
Size of residuals	Standardized root mean squared residual (SRMR)	SRMR ≤ 0.08	0.060—good fit
Size of residuals	The coefficient of determination (SD)	The greater, the better	0.7—good fit
