Most mobile cessation studies have found that such interventions have a higher quitting rate than interventions providing minimal smoking cessation support. However, why such interventions are effective has been almost unstudied by researchers.
This paper describes the principles of the personalized mobile cessation intervention-based WeChat app and used generalized estimated equations to assess why a personalized mobile cessation intervention was more likely to promote smokers from the preparation stage to the action stage than a nonpersonalized intervention.
This is a 2-arm, double-blind, randomized controlled trial in five cities in China. The intervention group received a personalized mobile cessation intervention. The control group received a nonpersonalized SMS text message smoking cessation intervention. All information was sent by the WeChat app. The outcomes were the change in protection motivation theory construct scores and the change in transtheoretical model stages.
A total of 722 participants were randomly assigned to the intervention or control group. Compared with those who received the nonpersonalized SMS text message intervention, smokers who received the personalized intervention presented lower intrinsic rewards, extrinsic rewards, and response costs. Intrinsic rewards were determinants of stage change, thus explaining why the intervention group was more likely to promote smokers from the preparation stage to the action stage (odds ratio 2.65, 95% CI 1.41-4.98).
This study identified the psychological determinants at different stages to facilitate smokers moving forward to the next stage of quitting behavior and provides a framework to explore why a smoking cessation intervention is effective.

大多数移动戒烟研究发现，此类干预措施的戒烟率高于提供最低限度戒烟支持的干预措施。然而，研究人员几乎没有研究过为什么这些干预措施是有效的。
本文描述了基于微信的个性化移动戒烟干预应用程序的原理，并使用广义估计方程评估为什么个性化移动戒烟干预比非个性化干预更有可能促使吸烟者从准备阶段进入行动阶段。
这是在中国五个城市进行的 2 臂、双盲、随机对照试验。干预组接受个性化移动戒烟干预，对照组接受非个性化短信戒烟干预。所有信息均通过微信应用程序发送。结局是保护动机理论结构评分的变化和跨理论模型阶段的变化。
共有 722 名参与者被随机分配到干预组或对照组。与接受非个性化短信干预的吸烟者相比，接受个性化干预的吸烟者内在奖励、外在奖励和反应成本较低。内在奖励是阶段变化的决定因素，因此解释了为什么干预组更有可能促使吸烟者从准备阶段进入行动阶段（优势比 2.65，95%置信区间 1.41-4.98）。
本研究确定了不同阶段的心理决定因素，以促进吸烟者向戒烟行为的下一阶段前进，并提供了一个探索戒烟干预措施有效的框架。
