We examined engagement in novel quit-smoking private social support networks on Twitter, January 2012 to April 2014. We mapped communication patterns within 8 networks of adult smokers (n = 160) with network ties defined by participants' tweets over 3 time intervals, and examined tie reciprocity, tie strength, in-degree centrality (popularity), 3-person triangles, 4-person cliques, network density, and abstinence status. On average, more than 50% of ties were reciprocated in most networks and most ties were between abstainers and nonabstainers. Tweets formed into more aggregated patterns especially early in the study. Across networks, 35.00% (7 days after the quit date), 49.38% (30 days), and 46.88% (60 days) abstained from smoking. We demonstrated that abstainers and nonabstainers engaged with one another in dyads and small groups. This study preliminarily suggests potential for Twitter as a platform for adult smoking-cessation interventions.
我们于2012年1月至2014年4月期间，研究了推特上新型戒烟私人社交支持网络中的参与情况。我们绘制了8个成年吸烟者网络（n = 160）内的交流模式，网络联系由参与者在3个时间间隔内发布的推文定义，并研究了联系的互惠性、联系强度、入度中心性（受欢迎程度）、三人三角关系、四人小团体、网络密度和戒烟状态。平均而言，大多数网络中超过50%的联系是互惠的，且大多数联系存在于戒烟者和非戒烟者之间。推文形成了更多聚合模式，尤其是在研究早期。在各个网络中，35.00%（戒烟日期后7天）、49.38%（30天）和46.88%（60天）的人成功戒烟。我们证明了戒烟者和非戒烟者在二元组和小团体中相互交流。这项研究初步表明推特作为成人戒烟干预平台的潜力。
