Fit indices for structural equation models.

Model	χ2	df	χ2/df	RMSEA	SRMR	TLI	CFI
Model 1	112.03	48	2.33	0.05	0.04	0.82	0.90
Model 2	86.55	28	3.09	0.06	0.03	0.82	0.91
Model 3	168.20	88	1.91	0.04	0.04	0.87	0.93

RMSEA = root mean square error of approximation; SRMR = standardized root mean square residual on within level; TLI = Tucker-Lewis index; CFI = comparative fit index. Model 1 includes all controls, Model 2 controls for age at t₂, and Model 3 contains all moderator variables while controlling for age at t₂.
