Fit Statistics of the Longitudinal Model Selected

	Default Model (Our Model)	Saturated Model (All Paths Free)	Independence Model (All Paths = 0)
X² (chi-square) (the smaller the better)	537	< .001	4,230
Degrees of freedom (df)	417	0	496
X² / df (< 2 is good)	1.29	—	8.53
AGFI (> .90 is good)	.771	—	.109
CFI (> .90 is good)	.968	1.00	0
RMSEA (90% CI) (< .05 is good)	.046 (.033 to .056)	—	.233 (.226 to .239)
AIC (the smaller the better)	759	1,056	4,294

Note: AGFI = Adjusted Goodness of Fit Index; CFI = Comparative Fit Index; RMSEA = Root Mean Square Error Approximation; AIC = Akaike Information Criterion.
