3. Configural invariance: Factor loadings and intercepts are freely estimated, and factor means are fixed to 0	210.9	204.3	84	0.952	0.924	0.053	0.138	0.127
4. Metric invariance: Factor loadings are fixed to be equal, intercepts are freely estimated, and factor means are fixed to 0	216.2	244.8	90	0.946	0.921	0.055	0.063	0.175
5. Scalar invariance: Intercepts and factor loadings are constrained	232.0	256.1	96	0.943	0.922	0.054	0.068	0.175
6. Uniqueness invariance: Intercepts, factor loadings, and residual variances are constrained	290.7	568.8	108	0.891	0.867	0.071	<0.0001	0.256
