Table 4 and Table 5 display significant predictors of smoking-related baseline characteristics among chronic and depressed smokers, respectively. As displayed in the tables, DSM-IV criteria predicted a range of smoking-related variables. Among the most consistent predictors was giving up activities (a significant predictor of five of five variables among chronic smokers and three of three variables among depressed smokers) and spending a great deal of time (a significant predictor of three of five variables among chronic smokers and two of three variables among depressed smokers). Finally, although chronic smokers who did not endorse difficulty controlling use were more likely to report higher withdrawal, negative reinforcement smoking, and mood disturbance, the lack of variance in response to this item suggests that this finding may have been anomalous.
