研究目的是评估一种针对怀孕吸烟者的定制化自助戒烟干预措施（MiQuit）的可行性和可接受性。次要目的是评估MiQuit是否影响戒烟的认知决定因素，并提供该干预措施对戒烟效果的一系列潜在效应量。
进行了一项随机对照试验，怀孕吸烟者被分配接受MiQuit（一份定制化的自助宣传单，随后是为期11周的定制化短信计划），或被分配到对照组，接受一份非定制化的自助宣传单。参与者是由英国7个国民医疗服务体系信托机构的社区助产士确定的207名怀孕吸烟者。在3个月的随访中，评估了干预措施的可接受性、戒烟的认知决定因素以及吸烟结果（自我报告的和经可替宁验证的7天时点戒烟率）。
可行性：94%（95%置信区间89% - 99%）的MiQuit参与者报告收到了两种干预成分。可接受性：9%（95%置信区间4% - 15%）的MiQuit参与者选择停止接收短信。机制：与对照组相比，MiQuit参与者更有可能设定戒烟日期（p = 0.049），并且报告了更高水平的自我效能感（p = 0.024）、危害认知（p = 0.052）和戒烟决心（p = 0.019）。潜在疗效：自我报告的戒烟率——MiQuit为22.9%，对照组为19.6%；优势比（OR）= 1.22，95%置信区间0.62 - 2.41；经可替宁验证的戒烟率——MiQuit为12.5%，对照组为7.8%；OR = 1.68，95%置信区间0.66 - 4.31。
通过宣传单和短信向怀孕吸烟者提供定制化的戒烟支持是可行且可接受的。MiQuit对认知决定因素和设定戒烟日期可能性的积极影响令人鼓舞。有必要进行更大规模的疗效试验。
Study aims were to assess the feasibility and acceptability of a tailored self-help smoking cessation intervention for pregnant smokers (MiQuit). Secondary aims were to assess whether MiQuit affected cognitive determinants of quitting and to provide a range of potential effect sizes of the intervention effect on smoking abstinence.A randomized controlled trial was undertaken in which pregnant smokers were allocated to either receive MiQuit, a tailored self-help leaflet followed by an 11-week program of tailored text messages, or to a control group, receiving a nontailored self-help leaflet. Participants were 207 pregnant smokers identified by community midwives across 7 NHS Trusts (United Kingdom). At 3-month follow-up, intervention acceptability, cognitive determinants of quitting, and smoking outcomes (self-reported and cotinine-validated 7-day point prevalence abstinence) were assessed.Feasibility: 94% (95% CI 89%-99%) of MiQuit participants reported receiving both intervention components. Acceptability: 9% (95% CI 4%-15%) of MiQuit participants opted to discontinue the text messages. Mechanism: compared with controls, MiQuit participants were more likely to set a quit date (p = .049) and reported higher levels of self-efficacy (p = .024), harm beliefs (p = .052), and determination to quit (p = .019). Potential efficacy: self-reported abstinence-MiQuit 22.9%, control 19.6%; odds ratio (OR) = 1.22, 95% CI 0.62-2.41; cotinine-validated abstinence-MiQuit 12.5%, control 7.8%; OR = 1.68, 95% CI 0.66-4.31.Delivering tailored smoking cessation support to pregnant smokers via leaflet and text message is feasible and acceptable. The positive effects of MiQuit on cognitive determinants and the likelihood of setting a quit date are encouraging. A larger efficacy trial is warranted.
