First, rates of the five types of childhood maltreatment are described for participants with baseline alcohol and nicotine dependence; and by persistence status within these groups. Second, logistic regressions assessed the effects of these maltreatment variables on (a) the persistence of alcohol dependence among those with baseline alcohol dependence and (b) the persistence of nicotine dependence for those with baseline nicotine dependence. For each outcome (alcohol and nicotine persistence), separate regressions were performed for each of the five childhood maltreatment variables controlling for demographics (age, gender, ethnicity, education) (Model 1) and controlling for demographics plus other adverse childhood experiences (Model 2). The purpose of Model 2 was to determine whether significant associations remained after controlling for other childhood adversities. Third, logistic regression models including all maltreatment types as predictors were run for both alcohol persistence (among those with baseline alcohol dependence) and nicotine persistence (among those with baseline nicotine dependence). These models controlled for demographics specified above, and were run to determine the unique effects of the varied maltreatment types. Fourth, logistic regressions were run to determine whether having more
