Recent theoretical and empirical work has led to debate over the benefit of delaying the implementation of a decision to quit smoking in order to plan the attempt. These two need not be linked, planning can occur before a commitment to quit is made, or after it is implemented, as well as in between. This study will test whether there are independent benefits for encouraging smokers to act immediately on a definite decision to quit smoking, and to engage in structured planning.
METHODS/DESIGN: A complex randomised controlled trial with a factorial design, testing the presence of a recommendation to quit immediately (or not) and encouragement to structured planning (or not) as additions to standard care, a web-based automated tailored advice program (QuitCoach). Participants are recruited from users of the QuitCoach who reside in Australia, do not report a mental health condition for which they are taking medication, are adult daily smokers, and at least open to the possibility of quitting. For the Immediate arm they could not have committed to quit within 2 days, while the Planning arm included all these and those quit within the last 4 days. This creates 6 groups: 2 × 3, with 2 × 2 fully randomised, and 2 only randomised for the planning arm. Follow-up assessments are conducted around 1 month (targeting two weeks after the quit attempt started), and 6 months later. The primary outcome is 6-month sustained abstinence at 6 months. Secondary outcomes include point-prevalence abstinence at both follow-ups, and making quit attempts during the intervention period. We will also explore differences in actual behaviour (timing and planning) by intervention, and relate this to outcomes.
This study will result in a better understanding of the roles of planning and delay in influencing the success of quit attempts.

最近的理论和实证工作引发了关于推迟实施戒烟决定以计划戒烟尝试是否有益的争论。这两者不一定相关，计划可以在做出戒烟承诺之前、之后或在实施过程中进行。本研究将测试鼓励吸烟者立即对明确的戒烟决定采取行动并进行结构化计划是否有独立的益处。
方法/设计：一项具有析因设计的复杂随机对照试验，测试立即戒烟（或不）和鼓励结构化计划（或不）的建议作为标准护理的附加内容的效果，即基于网络的自动化个性化咨询计划（QuitCoach）。参与者是从居住在澳大利亚的 QuitCoach 用户中招募的，他们没有报告正在服用药物的心理健康状况，是成年每日吸烟者，并且至少对戒烟持开放态度。对于立即戒烟组，他们不能在 2 天内承诺戒烟，而计划戒烟组则包括所有这些以及在过去 4 天内戒烟的人。这创建了 6 个组：2×3，其中 2×2 是完全随机分组，而只有 2 个仅在计划组中随机分组。随访评估在大约 1 个月（针对戒烟尝试开始后两周）和 6 个月后进行。主要结局是 6 个月时的持续戒烟率，6 个月时。次要结局包括两个随访点的即时戒烟率和干预期间的戒烟尝试。我们还将探索干预对实际行为（时间和计划）的影响，并将其与结局相关联。
这项研究将有助于更好地理解计划和延迟在影响戒烟尝试成功率方面的作用。
