Table 2 provides fit statistics for each model applied to the data (or subsets thereof) and correlations among all substance dependence criteria are provided in Supplemental Tables S1 and S2. The hierarchical model presented in Figure 1 fit well when modeling all data as a single sample. Similarly, model fit was good within each of the individual groups (although the ever use criterion for cocaine was dropped from the model for SAGE males, due to multicollinearity between this and other criteria that prevented the model from converging on a solution).
