Prochaska and DiClemente's (1984) cyclic-stage model of self-initiated smoking cessation divides the cessation process into five stages. This model was applied to a young adult population to determine the cross-sectional distribution of stages and the frequency and pattern of changes among stages over time. Compared to older adults, the distribution of the stages differed substantially: There were twice as many relapsers and only half as many maintainers among young adults. One-year changes in stages were examined using a static model, which did not take into account the cyclic nature of the change process, and a more realistic dynamic model, which did. Both models, especially the dynamic model, suggested substantially more movement among stages in younger than in older adults.
普罗查斯卡和迪克莱门特（1984年）的自我戒烟循环阶段模型将戒烟过程分为五个阶段。该模型应用于年轻成年人群体，以确定各阶段的横断面分布以及随时间推移各阶段之间变化的频率和模式。与老年人相比，各阶段的分布有很大差异：年轻成年人中的复吸者数量是老年人的两倍，而保持戒烟状态者的数量只有老年人的一半。使用一个未考虑变化过程循环性质的静态模型和一个更符合实际的动态模型来研究各阶段的一年变化情况。两个模型，尤其是动态模型，都表明年轻人各阶段之间的变化比老年人多得多。
