Model fit statistics for one-factor and two-factor models ().

Fit indices (model fit criteria)	One-factor model	Two-factor model
(df), (nonsignificant)	58.31 (27),	20.17 (19),
RMSEA (90% CI), (<0.08)	0.11 (0.07, 0.15),	0.03 (0.00, 0.09),
CFI (>0.95)	0.93	0.99
TLI (>0.95)	0.90	0.99
SRMR (<0.05)	0.05	0.03

Note: df = degrees of freedom; RMSEA = root mean square error of approximation; CI = confidence interval; CFI = comparative fit index; TLI = Tucker-Lewis index; SRMR = standard root mean square residual.
