The main objective of this study was to test the longer-term and differential efficacy of a mobile phone‒based life-skills training program designed to prevent substance use among adolescents.
A 2-arm, parallel-group, cluster RCT with assessments at baseline and follow-up after 6 and 18 months was conducted. The efficacy of the intervention was compared with that of an assessment-only control condition.
SETTING/PARTICIPANTS: A total of 1,473 students with a mean age of 15.4 years were recruited in 2019/2020 within 89 Swiss secondary and upper secondary school classes.
The automated intervention program included online feedback and individually tailored text messages provided over 22 weeks. The contents were based on social cognitive theory and addressed self-management, social, and substance use resistance skills.
Primary outcomes included 30-day prevalence rates for problem drinking and tobacco use.
The 18-month follow-up assessments were completed by 1,232 study (83.6%) participants. Those in the intervention group reported lower tobacco-smoking prevalence than the controls (OR=0.67; 95% CI=0.47, 0.96), but no significant difference in problem drinking (OR=0.84; 95% CI=0.61, 1.17) was observed. Among secondary outcomes, the intervention was effective at reducing cannabis-smoking prevalence (OR=0.55; 95% CI=0.39, 0.76) and cannabis use days (Cohen's d= -0.19; 95% CI= -0.29, -0.09), whereas no effects were observed for quantity of alcohol use, quantity of cigarettes smoked, well-being, or social skills. No significant moderators of the primary outcomes were observed.
An automated mobile phone‒based life-skills training program produced longer-term effectiveness in preventing tobacco smoking and cannabis use, whereas no effects were observed for problem drinking. These results suggest that digitally delivered life-skills training programs are similarly effective and are an easy-to-implement alternative to training conducted within a school curriculum.

本研究的主要目的是测试一种基于手机的生活技能培训计划的长期和差异化效果，该计划旨在预防青少年的物质使用。
这是一项 2 臂、平行组、群组 RCT 研究，在基线和 6 个月和 18 个月后的随访时进行评估。将干预的效果与仅评估对照条件进行比较。
设置/参与者：2019/2020 年，共在瑞士 89 所中学和高中的 89 个班级中招募了 1473 名平均年龄为 15.4 岁的学生。
自动化干预计划包括在线反馈和在 22 周内提供的个性化短信。内容基于社会认知理论，涉及自我管理、社会和物质使用抵制技能。
主要结果包括 30 天内饮酒和吸烟问题的流行率。
共有 1232 名研究（83.6%）参与者完成了 18 个月的随访评估。与对照组相比，干预组报告的吸烟流行率较低（OR=0.67；95%CI=0.47,0.96），但饮酒问题无显著差异（OR=0.84；95%CI=0.61,1.17）。在次要结果中，干预对减少大麻吸烟流行率（OR=0.55；95%CI=0.39,0.76）和大麻使用天数（Cohen's d=-0.19；95%CI=-0.29,-0.09）有效，而对饮酒量、吸烟量、幸福感或社交技能没有影响。主要结果的显著调节因素未见。
基于手机的自动化生活技能培训计划在预防吸烟和大麻使用方面具有长期效果，而对饮酒问题则没有影响。这些结果表明，数字交付的生活技能培训计划同样有效，是在学校课程中进行培训的一种易于实施的替代方案。
