Fitting of Trivariate Cholesky Structural Equation Models

Model		−2lnL	df	AIC	Δ-2lnL	Δdf	p
1	ACE	2069.93	1169	−268.07
2	AE with C for Depression	2069.99	1174	−278.02	0.06	5	> 0.99
3	AE	2070.37	1175	−279.63	0.44	6	> 0.99

5	E	2104.65	1181	−257.35	34.72	12	< 0.001

Note: ep = estimated parameters; lnL = log-likelihood; df = degrees of freedom; AIC = Akaike information criterion; Depression = Brief Symptom Inventory-53, Depression scale. Δχ² and Δdf are relative to the base model. The best fitting model is shown in bold.
