目前的文献表明，形成关于如何拒绝香烟的实施意图（简单的“如果-那么”计划）可能是减少青少年开始吸烟的有效干预措施。这项研究是一项务实的试验，旨在测试这种干预措施在减少英国青少年开始吸烟方面的有效性和成本效益。一项整群随机对照试验，至少有 36 所学校随机接受实施意向干预，目标是减少吸烟（干预组）或增加家庭作业（对照组）。干预措施将在课堂上进行，并在四年内每六个月重复一次（八次干预措施）。将在基线以及基线后 12、24、36 和 48 个月进行客观评估（一氧化碳监测仪）和自我报告的吸烟情况以及吸烟相关认知（例如吸烟意图、态度、规范和自我效能）。基线后 48 个月客观评估吸烟情况将是主要结果变量。健康经济分析将评估获得的生命年数。试验结果将提供关于拒绝香烟的重复实施意图对青少年开始吸烟率的影响的信息。 ISRCTN27596806
The current literature suggests that forming implementation intentions (simple ‘if-then’ plans) about how to refuse the offer of a cigarette may be an effective intervention to reduce smoking initiation in adolescents. This study is a pragmatic trial to test the effectiveness and cost-effectiveness of such an intervention in reducing smoking initiation in a sample of UK adolescents. A cluster randomised controlled trial with at least 36 schools randomised to receive an implementation intention intervention targeting reducing smoking initiation (intervention group) or increasing homework (control group). Interventions will be conducted at the classroom level and be repeated every six months for four years (eight interventions). Objectively assessed (carbon monoxide monitor) and self-reported smoking plus smoking related cognitions (e.g., smoking intentions, attitudes, norms and self-efficacy) will be assessed at baseline and 12, 24, 36 and 48 months post baseline. Objectively assessed smoking at 48 months post baseline will be the primary outcome variable. Health economic analyses will assess life years gained. The results of the trial will provide information on the impact of a repeated implementation intention for refusing offers of cigarettes on rates of smoking initiation in adolescents. ISRCTN27596806
