Prediction of number of arrests during the 4-month follow-up: Zero-inflated Poisson regression (N = 261)

Predictors of arrest (yes/no) Predictors of number of arrests (if arrested)

MDE in 30 days prior to baseline (y/n) −.62 .91 −.68 .494 .43 .38 1.11 .267
Baseline number of lifetime arrests −.03 .02 −1.46 .144 .02 .01 3.00 .003

Note: Significant p-values (< .05) are bolded to allow easy comparison of the predictors of yes/no arrest vs. predictors of number of arrests (if arrested).
