or reported point prevalence abstinence at pretest, 1 month, and 6 months. Although this report of the study does not focus on treatment effects, we can report that there were no signifi- cant interaction effects between interventions and stage at 1 and 6 months. At 6 months, interventions were continuing, so 12- and 18-month follow-ups are more appropriate measures of treatment outcome. An extensive examination of these results is under way and will be reported in a subsequent publication. Stage effects, however, were dramatic both at 1 month and 6 months. Over the period from 1 month to 6 months, there was a gradual increase in reported cessation activity for each of the three stage groups, with PC, C, and PA groups increasing in the proportion of subjects who stopped smoking in sequential fash- ion as predicted by the model.
