我们评估了QuitNet的社交网络结构，QuitNet是最大的行为改变在线社区之一，并将其特征与其他已知的社交网络进行了比较。使用现代网络分析方法，我们确定了在60天内活跃的QuitNet成员，沿着他们的联系。然后，我们从连接和通信模式中派生出多个子组，例如关键参与者和集成商。在7569名参与者中，我们确定了103592个连接到其他成员。社交网络整合的增加与女性、年龄较大、在系统中的时间较长以及不吸烟的可能性增加有关。QuitNet社区是一个大型社交网络，具有可持续的社会支持和社会影响力所需的特征，以促进戒烟和禁欲。这些特征包括成员随时间的持续性，吸烟状态的异质性，以及丰富的双向通信的证据。我们确定的一些有影响力的亚组可能为未来的网络级干预提供目标。
We evaluated the social network structure of QuitNet, one of the largest online communities for behavior change, and compared its characteristics to other known social networks. Using modern network analysis methods, we identified QuitNet members who were active during a 60-day period, along with their ties. We then derived multiple subgroups, such as key players and integrators, from connections and communication patterns. Among 7569 participants, we identified 103592 connections to other members. Metrics of social network integration were associated with increased likelihood of being female, being older, having been in the system longer, and not smoking. The QuitNet community is a large-scale social network with the characteristics required for sustainability of social support and social influence to promote smoking cessation and abstinence. These characteristics include persistence of members over time, heterogeneity of smoking status, and evidence of rich, bidirectional communications. Some of the influential subgroups we identified may provide targets for future network-level interventions.
