Results of the CFA by model and indices

Model	Absolute fit (RMSEA)	Incremental fit (CFI)	Parsimonious fit (Chisq/df)
Model 1	.113	.838	4.796
Model 2	.117	.841	5.000
Model 3	.067	.950	2.320
Model 4	.074	.943	2.603
Model 5	.071	.953	2.476

Model 1—all items without co-variance of the two factors; model 2—E1 is removed; model 3—E1 removed and the two factors were allowed to correlate; model 4—C1 removed and the two factors were allowed to correlate; model 5—C1 and E1 removed and the two factors were allowed to correlate

RMSEA root mean square error of approximation, CFI confirmatory fit index, Chisq/df chi-square/degrees of freedom
