Parameter Estimates and Standard Errors for Unconditional Growth Models of Externalizing Behavior With Unconstrained and Constrained Error Variances

Model	Intercept factor		Slope factor		RMSEA	CFI	χ2	df	p	Δχ2	Δdf	BCC
	Estimate	SE	Estimate	SE
Unconstrained error variances					.00	1.0	.157	1	.69	—	—	16.41
Constrained error variances	4.92** (10.43**)	.23 (1.37)	−.24* (0.94**)	.11 (0.36)	.00	1.0	.890	3	.83	.73	2	13.07

Note. RMSEA = root-mean-square error of approximation; CFI = comparative fit index; BCC = Browne-Cudeck criterion. Estimates and standard errors are shown for the growth model used in analyses (the model with constrained error variances). Average intercept and slope values and their standard errors are listed without parentheses. Variability estimates of the intercept and slope and their standard errors are shown in parentheses.
