Model fit statistics for tests of measurement invariance in the global disordered eating attitudes and behavior scale at EAT I, EAT II, and EAT IV
| Model | df | x2 | CFI | TLI | RMSEA (CIa) |
|---|---|---|---|---|---|
| Congeneric | 87 | 146.50 | .98 | .98 | .01 (.02 – .03) |
| Weak Invariance | 95 | 154.94 | .98 | .98 | .02 (.01 – .03) |
| Strong Invariance | NA | NA | NA | NA | NA |
| Adjusted strong invariance model | 94 | 149.29 | .98 | .98 | .02 (.01–.03) |
Note.

90% confidence interval limits for testing RMSEA. All estimates were significant at p < .01; df = degrees of freedom; χ2 = chi-square fit statistic; CFI = Comparative Fit Index; TLI = Tucker-Lewis Index; RMSEA = Root Mean Square Error of Approximation.
