Tobacco dependence treatment is recognized as a dynamic, chronic process comprised of several specific phases. Of these phases, the Cessation phase is the most critical as it has demonstrated the strongest relation to quit success. Yet, little is understood about smoking trajectories during this period. The current study aimed to address gaps in the smoking research literature and advance understanding of the dynamic quit process unique to completing an integrated smoking treatment by evaluating quit behavior during the Cessation phase.
Two hundred and sixty-seven treatment seeking smokers enrolled in a clinical trial to evaluate the efficacy of a novel, integrated smoking cessation treatment (46.1% male; M = 39.25, SD = 13.70) were included in the present study. Repeated-measure latent class analysis was employed to evaluate quit patterns from quit day through day 14 post-quit.
Results supported a four-class solution: Consistent Quitters, Non-Quitters, Relapsers, and Delayed Quitters. Predictors of class membership included age, number of prior quit attempts, motivation to quit smoking, and quit day smoking urges. Moreover, class membership was significantly associated with 6-month abstinence.
Results suggest that there are four relevant classes of quit behavior, each with specific predictor variables including age, motivation to quit, smoking urges, and number of quit attempts, and that these classes relate to long-term abstinence. These results have the potential to inform manualized smoking cessation treatment interventions based on relevant subgroups of quit behavior.
烟草依赖治疗被认为是一个动态的、慢性的过程，由几个特定的阶段组成。在这些阶段中，戒烟阶段最为关键，因为它与戒烟成功的关系最强。然而，人们对这一时期的吸烟轨迹知之甚少。本研究旨在解决吸烟研究文献中的空白，并通过评估完成综合戒烟治疗期间的戒烟行为，深入了解独特的戒烟动态过程。
本研究纳入了 267 名寻求治疗的吸烟者，他们参加了一项临床试验，以评估一种新型综合戒烟治疗的疗效（46.1%为男性；M=39.25，SD=13.70）。采用重复测量潜在类别分析来评估戒烟日至戒烟后第 14 天的戒烟模式。
结果支持了四种戒烟模式：持续戒烟者、非戒烟者、复吸者和延迟戒烟者。类别的预测因素包括年龄、戒烟尝试次数、戒烟动机和戒烟日吸烟冲动。此外，类别的归属与 6 个月的戒烟率显著相关。
结果表明，有四种相关的戒烟行为类别，每个类别都有特定的预测变量，包括年龄、戒烟动机、吸烟冲动和戒烟尝试次数，而且这些类别与长期戒烟有关。这些结果有可能为基于戒烟行为的相关亚组的戒烟治疗干预提供依据。
