To assess the effectiveness of including a social support intervention ('buddy system') in a group treatment programme to aid smoking cessation.
Five hundred and sixty-three smokers attended groups at a smokers' clinic. These groups were randomized either to be (a) groups in which smokers were paired with another person to provide mutual support (buddy condition: n=237 in 14 groups) or (b) to receive the same treatment without the buddy component (control: n=326 in 20 groups). Participants were seen weekly for the first 4 weeks after stopping then followed up again after 26 weeks.
Smokers in the buddy condition were no more likely than smokers in the control condition to stay abstinent at 1, 4 or 26 weeks. The effect was in the right direction at week one post-quit but after controlling for potential confounders the difference was not significant (odds ratio=1.45 (95% CI; 0.92-2.29), p=0.06).
We were unable to show that a buddy system improved abstinence rates of group treatment programmes. This might be due to the high level of social support already achieved through the groups.
The buddy system is a simple and very low cost addition to a group treatment programme; but the results from this study suggest that the kind of buddy system tested may not add substantially to the success rates. However there may be merits in a more intensive or protracted form of buddying.
评估在团体治疗项目中加入社会支持干预措施（“伙伴制度”）对帮助戒烟的有效性。
563名吸烟者参加了一家戒烟诊所的团体治疗。这些团体被随机分为两组：（a）吸烟者与另一人配对以提供相互支持的组（伙伴组：14个组，共237人）；（b）接受相同治疗但没有伙伴组成部分的组（对照组：20个组，共326人）。参与者在戒烟后的前4周每周接受一次检查，然后在26周后再次进行随访。
在1周、4周或26周时，伙伴组的吸烟者与对照组的吸烟者相比，戒烟成功的可能性并无差异。在戒烟后第1周时效果朝着正确方向发展，但在控制潜在混杂因素后，差异并不显著（优势比 = 1.45（95%置信区间：0.92 - 2.29），p = 0.06）。
我们无法证明伙伴制度能提高团体治疗项目的戒烟成功率。这可能是由于团体治疗已经提供了高水平的社会支持。
伙伴制度是团体治疗项目中一种简单且成本极低的补充措施；但本研究结果表明，所测试的这种伙伴制度可能不会显著提高成功率。然而，更密集或更持久形式的伙伴关系可能有其优点。
