  TLI RMSEA (90% CI) RMSR BIC SABIC
One factor 0.836 0.082 (0.071, 0.092) 0.064  − 194.227 50.053
Two factors 0.905 0.063 (0.049, 0.075) 0.046  − 224.492  − 21.454
Three factors 0.979 0.030 (0.000, 0.047) 0.030  − 238.140  − 73.172
Four factors 1.008 0.000 (0.000, 0.029) 0.022  − 204.908  − 74.837
Five factors 1.014 0.000 (0.000, 0.027) 0.017  − 157.549  − 59.203
  1. A good fit is defined by TLI > 0.95, RMSR < 0.05, and RMSEA < 0.06 with lower value of CI close to 0 and upper value no more than 0.08
