Table 3.
Fit indices for structural models. Nonsignificant χ2 statistics and χ2/df < 2 represent good fit to data. Lower AIC values indicate better fit, whereas higher CFI values represent good fit. See explanations of fit indices in Data analysis section. AIC, Akaike information criterion; CFI, comparative fit index; df, degree of freedom.
