TABLE 2.

Model fit indices for the four models tested.

Model	χ2 (df)	CFI	TLI	RMSEA (90% CI)
The original three-factor model	1,792.196 (186)	0.969	0.965	0.075 (0.072–0.078)
The tripartite three-factor model	1,815.892 (186)	0.968	0.964	0.076 (0.072–0.079)
Two-factor model	1,874.961 (188)	0.967	0.963	0.076 (0.073–0.079)
One-factor model	1,984.936 (189)	0.965	0.961	0.078 (0.075–0.082)

df, degree of freedom; TLI, Tucker–Lewis Index; CFI, Comparative Fit Index; RMSEA, root mean square error of approximation; 90% CI, 90% confidence interval for RMSEA.
