The present study examined the moderating effects of two measures of future orientation on the relation between intention, planning, and past behavior on the one hand, and quitting smoking on the other. The degree of future orientation was assessed by the Consideration of Future Consequences (CFC) Scale and the Stanford Time Perspective Inventory (STPI). Both CFC and STPI significantly moderated the intention–quitting behavior and past behavior–quitting behavior relationships. CFC also moderated the relation between planning and quitting behavior, whereas STPI failed to moderate the planning–quitting relation. The results indicate that the extent to which a person is future oriented represents an important moderating variable when it comes to the relation between deliberative processes and actual behavior. The implications of the results are discussed.
