The aim of this study was to explore whether factors predicting making a quit attempt are uniform within the preparation stage of the transtheoretical model (TTM). Participants were 283 smokers, all planning to quit in the next 30 days (preparation stage), who used a computer-generated tailored advice programme. Evidence of differences in prediction of making a quit attempt was found between smokers with and without a quit date, with the predictive power of a multivariate model markedly higher among those with a set date. In particular, one aspect of pros of smoking (smoking helps you feel better when things are bad) was predictive of progression among those with a quit date, but not among those without. The results suggest that factors predicting stage progression are not uniform within the preparation stage. The results complement other recent research that has questioned the stage definitions used in the TTM and provide evidence in support of an alternative stage boundary defined by the commitment of setting a quit date.
本研究旨在探讨在跨理论模型（TTM）的准备阶段，预测戒烟尝试的因素是否具有一致性。研究对象为 283 名计划在未来 30 天内戒烟的吸烟者（准备阶段），他们使用计算机生成的个性化建议计划。研究结果表明，有戒烟日期和没有戒烟日期的吸烟者在预测戒烟尝试方面存在差异，有明确戒烟日期的吸烟者的多变量模型预测能力明显更高。特别是，吸烟的好处之一（吸烟可以帮助你在心情不好时感觉更好）在有戒烟日期的吸烟者中具有预测进展的作用，但在没有戒烟日期的吸烟者中则没有。研究结果表明，在准备阶段，预测阶段进展的因素并不具有一致性。这些结果补充了其他最近质疑 TTM 使用的阶段定义的研究，并为支持以设定戒烟日期为界限的替代阶段定义提供了证据。
