The fit indexes of the CFA in the undergraduate sample and clinical sample.

							RMSEA 90%CI
	χ2/df	PGFI	IFI	TLI	CFI	RMSEA	LO90	HI90
Undergraduate students	3.440	0.675	0.922	0.905	0.922	0.065	0.060	0.071
Clinical patients	2.923	0.650	0.935	0.922	0.935	0.077	0.070	0.084

χ², Chi-square; df, degrees of freedom; PGFI, parsimonious goodness-of-fit index; IFI, incremental fit index; TLI, Tucker– Lewis index; CFI, comparative fit index; RMSEA, root-mean-square error of approximation; LO90 and HI90 indicate lower and upper end of the 90% confidence interval of the RMSEA.
