In this study, the utility and validity of three behavioral milestones, initial abstinence, lapse, and relapse, were investigated as an organizational framework for assessing and reporting outcomes in smoking cessation research. Tests of the framework were twofold: First, to establish that each milestone represented a significant barrier to successful smoking cessation, the proportion of participants failing to meet abstinence criteria at each milestone was investigated. Second, differences in variables that predicted outcomes between the milestones were examined. Changes in the importance of factors that predicted outcomes between the milestones were to suggest differences in the processes contributing to changes in trajectory towards end-state failure or success. The utility and validity of the milestones as an organizational framework was partially supported insofar as all of the milestones represented significant barriers to successful smoking cessation. However, few predictors of any outcome were identified. As a consequence, few instances of differential prediction between outcomes were found. This study, therefore, did not provide support for the utility of the milestones framework because preliminary findings did not provide an appropriate context in which it could be tested as a tool for identifying differential predictors of initial abstinence, lapse, and relapse.
