Chi-square, CFI, and RMSEA Model Fit Indices for Best-Fitting Models for Exercise and Drinking Outcomes

Variable	χ²(df)	CFI^a	RMSEA^b	TLI^a	SRMR^b
Exercise Volume	33.88 (7)^*	0.54	.236	−.17	.102
Binge Drinking Episodes	14.68 (11)	0.97	.069	.95	.042
Drinks per Week	12.80 (7)	0.91	.109	.77	.104
Drinking Consequences	2.21 (4)	>0.99	<.001	1.08	.025

Note. CFI = Comparative Fit Index. RMSEA = Root Mean Square Error of Approximation. SRMR = Standardized Root Mean Square Residual. TLI = Tucker-Lewis Index.

Cardiorespiratory fitness model fit indices are not depicted because this variable showed no change over time. Exercise frequency model fit indices are not depicted because negative binomial models produced in Mplus do not yield fit indices. Variations in degrees of freedom between models are due to differences in model specification (i.e., linear vs. piecewise) and number of assessment points.

CFI and TLI values of .95 and larger indicate good model fit and values of .90 and larger indicate adequate fit.

RMSEA and SRMR values of .05 and lower indicate good model fit and values of .08 and lower indicate adequate fit.
