Goodness-of-fit indices obtained for compared structural models of the TEPS in undergraduate sample (sample 2)

	X2	df	CFI	TLI	SRMR	RMSEA (90%CI)
Model1	2110.259	134	0.830	0.806	0.053	0.063 (0.061 0.066)
Model2	1392.040	113	0.886	0.863	0.046	0.056 (0.053 0.058)
Model3	1121.298	113	0.910	0.892	0.043	0.049 (0.047 0.052)
Second-level	1189.219	114	0.904	0.886	0.044	0.051 (0.048 0.053)

Note: Model 1 is the two-factor structure proposed by Gard (18 items and two factor structure) [15]. Model 2 is the four-factor structure proposed by Chan [24] with two added items, and item 7 regarded as expendable (20 items and four factor structure). Model 3 is our newly developed four-factor structure without item 7(18 items and four factor structure). X², Chi-square; df, degrees of freedom; CFI, comparative fit index; TLI, Tucker-Lewis index; SRMR, standardized root mean squared residual; RMSEA, root mean square error of approximation
