DESCRIPTION (provided by applicant): Stage theories of health behavior have been influential over the past 20 years. In the case of smoking cessation, the appeal and potential of a stage model is easily understood. Whereas many variables are associated with smoking cessation, it is difficult to organize these variables into a coherent theory of how people quit smoking. A stage model could help bring structure to these variables in a way that would inform interventions. If smokers could be arranged in an ordered set of stages, then interventions could be designed for each stage to foster progressive stage movements leading ultimately to cessation. The intuitive appeal of a stage model for smoking cessation is reflected by the widespread use of the stages of change over past 20 years. The stage of change construct is the linchpin of a larger model known as the Transtheoretical Model (TTM). However, several researchers recently have concluded that the TTM is insufficiently supported by empirical evidence. The hypothesis of the current application is that the stage of change construct systematically underestimates motivation to quit smoking, and that this systematic underestimation undermines research and interventions based on the TTM. An intervention study is proposed in which participants receive stage-matched interventions for smoking cessation. The three study conditions will use three different staging systems to determine the stage of each smoker. One staging system will be the stages of change. A second staging method will be an alterative developed by the PI. Past research has shown that these two systems produce significantly different stage distributions, and that the alternative algorithm classifies smokers as being significantly more motivated to quit compared to the stages of change algorithm. A third "system" is a control condition in which all smokers are treated as though they were highly motivated to quit. The hypothesis of the proposed study is that participants staged using the alternative staging system will evince greater rates of cessation and greater increases in motivation to quit smoking compared to participants staged with the stage of change algorithm, or participants assigned to the control condition. Given the prominence of the TTM in public health research and practice, this study could have far reaching implications for preventing cancer and other diseases by enhancing the effectiveness of smoking cessation interventions.

描述（由申请人提供）：健康行为的阶段理论在过去20年中一直很有影响力。在戒烟的情况下，阶段模型的吸引力和潜力很容易理解。虽然许多变量与戒烟有关，但很难将这些变量组织成人们如何戒烟的连贯理论。阶段模型可以帮助以一种为干预提供信息的方式为这些变量带来结构。如果吸烟者可以被安排在一个有序的阶段，那么干预措施可以为每个阶段设计，以促进渐进的阶段运动，最终导致戒烟。戒烟阶段模型的直观吸引力反映在过去20年中改变阶段的广泛使用中。变革阶段结构是一个更大的模型的关键，称为跨理论模型（TTM）。然而，一些研究人员最近得出结论认为，TTM没有得到经验证据的充分支持。当前应用的假设是，改变阶段结构系统地低估了戒烟的动机，这种系统性低估破坏了基于TTM的研究和干预措施。提出了一项干预研究，其中参与者接受阶段匹配的戒烟干预措施。三种研究条件将使用三种不同的分期系统来确定每个吸烟者的分期。一个阶段系统将是变化的阶段。第二种分期方法将是PI开发的替代方法。过去的研究表明，这两个系统产生显着不同的阶段分布，并且替代算法将吸烟者分类为与改变算法的阶段相比更有动力戒烟。第三个“系统”是一个控制条件，在这个条件下，所有的吸烟者都被视为有很高的戒烟动机。拟议研究的假设是，与使用变化阶段算法的参与者或分配到对照条件的参与者相比，使用替代分期系统分期的参与者将表现出更高的戒烟率和更大的戒烟动机增加。鉴于TTM在公共卫生研究和实践中的突出地位，这项研究可能对通过提高戒烟干预措施的有效性来预防癌症和其他疾病产生深远的影响。
