行为改变的跨理论模型的一个关键结构是改变的阶段（预先思考、沉思、准备、行动和维持）（Prochaska & DiClemente, 1988,1986）。本研究采用潜在转变分析（LTA; Collins & Wugalter, 1992; Collins, Wugalter, & Rousculp, 1991）来研究戒烟变化的各个阶段。LTA是一种评估分类结果的替代方法，它对变化敏感，具有诊断性，并允许对变化的替代模型进行比较。样本包括545名被动招募的吸烟者和戒烟者，他们在两年的时间里接受了五次评估。LTA用于比较三个指定模型。与数据拟合最好的模型表明，在6个月的时间框架内，各阶段之间既发生递进又发生回归，也发生两阶段递进。对各阶段之间运动概率的考察揭示了与跨理论模型一致的三个发现。首先，各个阶段的移动并不总是线性的。第二，向前移动的概率大于向后移动的概率。第三，移动到相邻阶段的概率大于两个阶段进展的概率。
A key construct of the Transtheoretical Model of Behavior Change is the stage of change (Precontemplation, Contemplation, Preparation, Action, and Maintenance) (Prochaska & DiClemente, 1983, 1986). This study applies Latent Transition Analysis (LTA; Collins & Wugalter, 1992: Collins, Wugalter, & Rousculp, 1991) to movement through the stages of change for smoking cessation. LTA is an alternative method of assessing categorical outcome that is sensitive to change, diagnostic, and allows for the comparison of alternative models of change. The sample consisted of 545 reactively recruited smokers and former smokers who were assessed five times over a two year period. LTA was used to compare three specified models. The model that fit the data best indicates that in a six month time frame both progression and regression among the stages takes place as well as two stage progression. Examination of the probability of movement among the stages revealed three findings consistent with the Transtheoretical Model. First, movement through the stages is not always linear. Second, the probability of forward movement was greater than backward movement. Third, the probability of moving to adjacent stages was greater than the probability of two stage progression.
