Table 2. The model fitness indicators in three samples.

Model	χ 2	df	P	CFI	TLI	RMSEA	CI90		P values	SRMR
Patients with schizophrenia	104.826	47	<0.0001	0.964	0.949	0.079	0.059	0.100	0.011	0.071
First-degree relatives	121.993	47	<0.0001	0.954	0.935	0.09	0.071	0.110	0.001	0.072
College students	332.336	47	<0.0001	0.971	0.96	0.059	0.053	0.065	0.005	0.047

Abbreviations: CFI, comparative fit index; df, degree of freedom; RMSEA, root mean square error of approximation; SRMR, standardized root mean square residual; TLI, Tucker–Lewis index.

Goodness-of-fit of the model for schizophrenia patients, first-degree relatives, and college students was assessed using multiple indicators, including χ², the CFI, TLI, RMSEA and its confidence interval, as well as the SRMR.
