Binge Eating Scale Confirmatory Factor Analysis

Model df χ2 CFI TLI RMSEA WRMR Δχ2 test comparing model 1 and 3
1 104 298.78 .96 .96 .06 1.17
2 103 291.09 .96 .96 .06 1.16
3 103 236.10 .97 .97 .05 1.03 47.17, df 1, p < .001

Note. χ2 = chi-square test. CFI = comparative fit index. TLI = Tucker Lewis Index. RMSEA = root mean square of approximation. WRMR = weighted root mean square residual. Model 1 = All items on one factor. Model 2 = Items on 2 factors with items 12 and 16 on Feelings/Cognitions. Model 3 = Items on 2 factors with items 10 and 16 on Behaviors. Model in bold is the best fitting model. Δχ2 test was not conducted to compare model 2 and 3 as they are non-nested.
