The SQ4U (Stay Quit for You)-study aims to test the efficacy of two computer tailored smoking relapse prevention programs which incorporate planning strategy assignments and provide tailored feedback at multiple time points after the quit-attempt. The programs differ in the support provided after the quit-attempt. This paper aims to describe the development and design of SQ4U.
METHODS/DESIGN: SQ4U-respondents were daily smokers in the 18-65 years age group, who were motivated to quit smoking and willing to make a quit-attempt within 1 month of registration. The study is a randomized controlled trial with three conditions: 1. Control group, 2. Action planning (AP) program, 3. Action planning plus (AP+) program. Respondents in the control group only filled out questionnaires. The AP program consisted of computer tailored baseline feedback based on the I-Change Model and six planning strategy assignments. The AP+ program provided the same program elements as the AP program, but was extended with tailored feedback at eleven time points after the quit-attempt. The feedback targeted (recovery) self-efficacy, planning and negative affect. There were two follow-up measurements at 6 and 12 months after baseline. User experiences and the efficacy of the programs in fostering seven-day point prevalence and continued abstinence were examined using a process evaluation and logistic regression analyses.
The present paper outlines the development and design of the SQ4U-study. This study has the potential to provide a new effective computer tailored smoking relapse prevention program as well as insight into effective smoking relapse prevention strategies.
SQ4U（为你戒烟）研究旨在测试两种计算机定制的戒烟后复发预防方案的疗效，这两种方案都纳入了计划策略任务，并在戒烟尝试后多个时间点提供定制反馈。这些方案在戒烟后提供的支持有所不同。本文旨在描述 SQ4U 的开发和设计。
方法/设计：SQ4U 受访者为年龄在 18-65 岁之间的每日吸烟者，他们有戒烟的动机，并愿意在注册后 1 个月内进行戒烟尝试。该研究是一项随机对照试验，分为三组：1.对照组，2.行动计划（AP）方案，3.行动计划加（AP+）方案。对照组的受访者只需填写问卷。AP 方案包括基于 I-Change 模型的计算机定制基线反馈和六项计划策略任务。AP+计划提供了与 AP 计划相同的计划要素，但在戒烟后 11 个时间点提供了定制反馈。反馈针对（恢复）自我效能、计划和负性情绪。在基线后 6 个月和 12 个月进行了两次随访测量。使用过程评估和逻辑回归分析来检查用户体验和方案在促进 7 天点患病率和持续戒烟方面的效果。
本文概述了 SQ4U 研究的开发和设计。这项研究有可能提供一种新的有效的计算机定制的戒烟后复发预防方案，并深入了解有效的戒烟后复发预防策略。
