INTRODUCTION
Engagement with online content and online social network integration are associated with smoking behavior change, but less is known about social dynamics of shared engagement between participants in group-based social media interventions.
METHODS
Participants were 251 young adult smokers aged 18 to 25 assigned to one of 29 secret Facebook groups tailored to their readiness to quit smoking ("pre-contemplation," "contemplation," and "preparation"). Groups varied in size and were randomly assigned to receive monetary incentives for engagement. All groups received daily posts for 90 days and were assessed for remote biochemically verified smoking abstinence at the end of the intervention. Across 29 groups, we examined associations between group features (group size, incentive condition, readiness to quit) with how connected members were within the group based on shared engagement with the same content (measured by density). At the individual level, we examined associations between 7-day biochemically verified smoking abstinence and how connected an individual was within the group (measured by degree centrality).
RESULTS
After adjusting for comment volume, being in a contemplation group (vs. pre-contemplation group) was associated with a decrease in comment-based density. Individual degree centrality was significantly associated with biochemically verified smoking abstinence for both comments and likes.
CONCLUSIONS
Future group-based social media interventions for smoking cessation may want to focus on promoting connected engagement between participants, rather than simply quantity of engagement.
IMPLICATIONS
Participants in a smoking cessation intervention delivered through Facebook groups were more likely to have biochemically verified smoking abstinence if they were more connected to the rest of the group via shared engagement. Promoting shared engagement between participants may be more likely to promote behavior change than volume of engagement alone.
简介
与在线内容的互动以及与在线社交网络的整合与吸烟行为的改变有关，但对于基于群组的社交媒体干预中参与者之间共享互动的社交动态知之甚少。
方法
参与者为 251 名年龄在 18 至 25 岁之间的年轻成年吸烟者，他们被分配到 29 个定制的秘密 Facebook 群组之一，这些群组根据他们戒烟的准备情况（“未考虑”、“考虑”和“准备”）进行定制。群组的大小不同，并随机分配接受参与度的金钱奖励。所有群组在 90 天内每天发布信息，并在干预结束时评估远程生物化学验证的吸烟戒断情况。在 29 个群组中，我们研究了群组特征（群组大小、激励条件、戒烟准备情况）与成员基于相同内容的共享参与度（通过密度衡量）之间的关联。在个体层面上，我们研究了 7 天生物化学验证的吸烟戒断与个体在群组中的连接程度（通过度中心性衡量）之间的关联。
结果
在调整了评论量后，与处于未考虑阶段的群组（与考虑阶段的群组相比）相比，评论的基于密度的密度下降与评论的密度下降有关。个体的度中心性与评论和点赞的生物化学验证的吸烟戒断均显著相关。
结论
未来的基于群组的社交媒体戒烟干预可能需要专注于促进参与者之间的连接互动，而不仅仅是参与的数量。
意义
通过 Facebook 群组提供的戒烟干预中，如果参与者通过共享互动与群组的其他成员更紧密地联系在一起，他们更有可能通过生物化学验证实现戒烟。促进参与者之间的共享互动可能比仅增加参与度更有可能促进行为改变。
