Table 4 Goodness of fit index and comparative fit indices for the doping opinion model depicted in Figure 1

From: Methodological considerations regarding response bias effect in substance use research: is correlation between the measured variables sufficient?

Fit index Good fit/Cut-off Model without SD Model with SD
Overall fit p > 0.05 χ2 = 111.0 df = 13, p < .001 χ2 = 39.3, df = 15, p = .001
  χ 2 /df <3 χ2/df = 8.544 χ2/df = 2.619
CFI CFI > 0.9 .729 0.935
TLI TLI > 0.9 .417 0.845
RMSEA RMSEA <0.05 .165 90%CI = .138, .194 .076 90%CI = .048, .106
PCLOSE PCLOSE > 0.05 <.001 .064
  1. CFI: comparative fit index; TLI: Tucker Lewis coefficient; RMSEA: root mean square error of approximation (<0.8 reasonable, <0.5 is good, > 0.1 is not good); PCLOSE: p of close fit (H0: RMSEA = 0.05)
