This study assessed the efficacy of the SinHumo App combined with a cognitive-behavioral smoking cessation treatment on 12-month follow-up abstinence, compared with the same smoking cessation treatment and a control App.
A sample of 288 treatment-seeking people who smoke were randomized: SinHumo App plus smoking cessation treatment (n = 140) and control App plus smoking cessation treatment (n = 148). The primary outcome was 7-day point prevalence abstinence (PPA) at the 12-month follow-up. Secondary outcomes were abstinence rates at the end of the intervention and 3- and 6-month follow-ups, cigarette per day (CPD) reduction over the 12-month follow-up, intervention engagement, and satisfaction.
Intention-to-treat analyses showed nonsignificant differences in self-reported 7-day PPA at the 12-month follow-up (37.1 and 42.6%, respectively; OR = 0.80). No significant differences were found in abstinence at the end of the treatment (68.6 vs. 62.8%) nor on 7-day PPA at 3- (35.7 vs. 45.9%) and 6-month (35.0 vs. 41.2%) follow-up. Complete case and multiple imputation analyses yielded similar results for abstinence outcomes. A significant reduction in CPD across the 12-month follow-up in the subsample of participants who smoked was observed, but nonsignificant differences between conditions were found. Higher engagement with the SinHumo App was a significant predictor of 12-month abstinence. Satisfaction with the intervention was high and similar in both groups.
High abstinence rates over the 12-month follow-up and satisfaction were found in both conditions. The inclusion of the SinHumo App did not improve abstinence rates in the intervention.
Scarce research has examined the long-term efficacy of smoking cessation treatments, including Apps, to support the quitting process. The present randomized controlled trial contributes to the existing literature about including information and communication technologies in behavior change interventions. The development of effective smoking cessation apps and information and communication technologies-based interventions is crucial for reducing the prevalence of smoking, as these interventions have the potential to reach a large number of people who smoke and reduce access-related barriers to treatment.
本研究评估了“SinHumo应用程序”联合认知行为戒烟治疗对12个月随访期戒烟效果的影响，并与单纯的戒烟治疗及一款对照应用程序进行比较。
选取288名寻求戒烟治疗的吸烟者作为样本，随机分为两组：“SinHumo应用程序”加戒烟治疗组（n = 140）和对照应用程序加戒烟治疗组（n = 148）。主要结局指标为12个月随访期的7日点患病率戒烟率（PPA）。次要结局指标包括干预结束时、3个月及6个月随访时的戒烟率，12个月随访期内每日吸烟量（CPD）的减少情况，干预参与度以及满意度。
意向性分析显示，12个月随访期自我报告的7日PPA无显著差异（分别为37.1%和42.6%；OR = 0.80）。治疗结束时的戒烟率（68.6%对62.8%）以及3个月（35.7%对45.9%）和6个月（35.0%对41.2%）随访时的7日PPA均无显著差异。完整病例分析和多重插补分析得出的戒烟结局结果相似。在吸烟参与者子样本中，观察到12个月随访期内CPD显著减少，但两组间无显著差异。对“SinHumo应用程序”的更高参与度是12个月戒烟的显著预测因素。两组对干预的满意度都很高且相似。
两种情况在12个月随访期内均有较高的戒烟率和满意度。纳入“SinHumo应用程序”并未提高干预组的戒烟率。
关于包括应用程序在内的戒烟治疗支持戒烟过程的长期疗效的研究较少。本随机对照试验为现有关于将信息通信技术纳入行为改变干预措施的文献做出了贡献。开发有效的戒烟应用程序和基于信息通信技术的干预措施对于降低吸烟率至关重要，因为这些干预措施有可能覆盖大量吸烟者并减少与治疗获取相关的障碍。
