Goodness of Fit Indices for Final Model (Model 3), Null Model, and Alternative Models

Model	df	χ 2	p-value	χ2/df	△χ2 (△df)	CFI	RMSEA	SRMR
Null Model	81	562.63	.00	6.93
Model 1	9	19.88	.02	2.21	--	.98	.09	.03
Model 2	17	29.84	.03	1.76	9.96(8)	.97	.07	.04
Model 3	19	30.27	.05	1.59	.43(2)	.98	.06	.04
Model 4	21	41.12	.01	1.99	10.85(2)*	.96	.08	.04
Model 5	23	41.65	.01	1.81	.53(2)	.96	.07	.04

Note. Models 1-5 were compared hierarchically. Model 1 vs. 2: Model 2 was not significantly better fitting but was more parsimonious than Model 1; Model 2 was retained. Model 2 vs. 3: Model 3 also was not significantly better fitting than Model 2 but was more parsimonious than Model 2; Model 3 was retained. Model 3 vs. 4: Model 4 was significantly worse fitting than Model 3; Model 3 was retained. (Model 4 vs. 5: Model 5 was not significantly better fitting than Model 4 but was more parsimonious; Model 5 was retained.) Model 3 vs. 5: Model 3 was a significantly stronger fit than Model 5, so Model 3 was determined to be the best fitting, final model.
