Note. AIC = Akaike information criterion; BIC = Bayesian information criterion; CI = confidence interval; Est. = estimation; FU = Familias Unidas; PAU = prevention as usual. Unstandardized coefficients are presented in the table. The zero-inflated growth model was used for drug use whereas the conventional growth curve model was used for sex without a condom. Seven cases were not included in the drug-use analyses because of an invalid response pattern.
