# of factors
extracted		 RMSEA CFI TLI SRMR
One-factor 0.176 0.763 0.683 0.090
Two-factor 0.121 0.921 0.851 0.052
Three-factor 0.034 0.996 0.988 0.012

Note. RMSEA = Root Mean Square Error of Approximation; CFI = Confirmatory Fit Index; TLI = Tucker-Lewis Index; SRMR = Standardized Root Mean Square Residual.
