Many young people report they want to stop smoking and have tried to do so, but most of their quit attempts fail. For adult smokers, there is strong evidence that group behavioural support enhances quit rates. However, it is uncertain whether group behavioural support enhances abstinence in young smokers trying to quit.
A cluster randomised trial for young people trying to stop smoking to compare the efficacy of a school-based 9 week intensive group behavioural support course versus a school-based 7 week brief advice only course. Participants were assessed for evidence of tobacco addiction and nicotine replacement therapy (NRT) was used if it was deemed appropriate by the therapist. Both types of course aimed to recruit approximately one hundred participants from approximately ten schools.The primary outcome was successful quitting at 4 weeks after quit day judged according to the Russell standard. Had the trial been completed, abstinence at 6 months after quit day and the relationships between successful quit attempts and 1) psychological assessments of dependence prior to quitting 2) salivary cotinine concentration prior to quitting and 3) sociodemographic characteristics would also have been assessed. The proportion of participants who stopped smoking in each arm of the trial were compared using Chi square tests.The trial was stopped shortly after it had started because funding to support the therapists running the stop smoking group behavioural support programme was withdrawn. Only three stop smoking courses were completed (two group support courses and one brief advice pharmacotherapy course). Seventeen participants in total entered the trial. At the end of the courses, one participant (10%) attending the group support programme had stopped smoking and no participant attending the brief advice programme had stopped smoking.
The trial was stopped so we were unable to determine whether group support helped more young people to stop smoking than brief advice. Engagement and recruitment of participants proved much more difficult than had been anticipated. Fifteen of the seventeen participants reported that quitting smoking was either pretty important or very important to them. Thus, the stop smoking success rate could, nevertheless, be considered disappointing.

许多年轻人表示他们想戒烟并已尝试过，但大多数戒烟尝试都失败了。对于成年吸烟者，有充分证据表明团体行为支持可提高戒烟率。然而，团体行为支持是否能提高试图戒烟的年轻吸烟者的戒断率尚不确定。
一项针对试图戒烟的年轻人的整群随机试验，比较以学校为基础的为期9周的强化团体行为支持课程与以学校为基础的为期7周的仅提供简短建议课程的效果。对参与者进行烟草成瘾证据评估，治疗师认为合适时使用尼古丁替代疗法（NRT）。两种课程都旨在从大约十所学校招募约一百名参与者。主要结局是根据拉塞尔标准判断在戒烟日4周后成功戒烟。如果试验完成，还将评估戒烟日6个月后的戒断情况以及成功戒烟尝试与以下因素之间的关系：1）戒烟前对依赖的心理评估；2）戒烟前唾液可替宁浓度；3）社会人口学特征。使用卡方检验比较试验各臂中戒烟的参与者比例。试验开始后不久就停止了，因为支持开展戒烟团体行为支持项目的治疗师的资金被撤回。总共只完成了三门戒烟课程（两门团体支持课程和一门简短建议药物治疗课程）。共有17名参与者进入试验。课程结束时，参加团体支持项目的一名参与者（10%）成功戒烟，参加简短建议项目的参与者无人戒烟。
试验停止了，所以我们无法确定团体支持是否比简短建议更有助于更多年轻人戒烟。事实证明，参与者的参与和招募比预期困难得多。17名参与者中有15人表示戒烟对他们来说要么相当重要要么非常重要。因此，戒烟成功率仍可能被认为令人失望。
