Fit Statistics for Multivariate Models of Laboratory-assessed 12-month Anger, and 36-month Anger and IC

	Overall Fit of Model			Relative Fit of Model
	−2LL	df	AIC	Δχ2	Δdf	p
1. Full Model	7716.42	2837	2042.42
2. No C on Anger 12, No A on IC 36	7718.22	2843	2032.22	1.80	6	.94
3. Model 2 plus No A Covariance	7718.49	2844	2030.49	2.07	7	.96
4. Model 2 plus No C Covariance	7760.01	2844	2072.01	43.58	7	.00
5. Model 2 plus No E Covariance	8125.21	2846	2433.21	408.79	9	.00

Note. −2LL = Likelihood Statistic. df = Degrees of freedom. AIC = Akaike’s Information Criterion.Δχ²= Difference in Chi-square between the full model and reduced models. Δdf = Difference in df between the full model and reduced models. Best-fitting model in bold. N=846 assessed for anger in the laboratory at 12 months; N=1000 assessed for anger in the laboratory at 36 months; and N=1021 children assessed for IC in the laboratory at 36 months.
