GLOBALink, a large online network of tobacco control professionals, was active in the promotion of the World Health Organization's Framework Convention on Tobacco Control treaty, an international treaty aimed at reducing the global burden of tobacco-related death and disease. We examined and compared the roles that different countries served in the GLOBALink community during FCTC negotiation and ratification. Previous studies of FCTC ratification found the process adhered to a diffusion of innovation model (Valente et al., 2015). We followed that work by conducting content analyses of discussion messages posted by GLOBALink members representing different countries. Based on the time when they ratified the FCTC, each country was labeled by one of the four adoption stages of the diffusion model and we investigated the amount of shared word use between the different stages. A goodness-of-fit chi-squared test indicated that content was not shared in an expected manner between stages ( = 11,856.45, = 51,447, < 0.001). A deeper look at the specific words shared between countries within and between adoption stages provided insight into how interactions between certain countries might have served to support the ratification process.
全球烟草控制专业人员在线网络（GLOBALink）积极推动世界卫生组织的《烟草控制框架公约》，这是一项旨在减轻全球烟草相关死亡和疾病负担的国际条约。我们研究并比较了不同国家在《烟草控制框架公约》谈判和批准过程中在GLOBALink社区中所扮演的角色。先前关于《烟草控制框架公约》批准的研究发现，该过程遵循创新扩散模型（瓦伦特等人，2015年）。我们在此基础上，对代表不同国家的GLOBALink成员发布的讨论信息进行了内容分析。根据各国批准《烟草控制框架公约》的时间，每个国家被标记为扩散模型的四个采用阶段之一，我们研究了不同阶段之间共享词汇的使用量。拟合优度卡方检验表明，各阶段之间的内容共享方式不符合预期（χ² = 11,856.45，自由度 = 51,447，p < 0.001）。深入研究采用阶段内和阶段间各国共享的具体词汇，有助于了解某些国家之间的互动如何可能支持批准过程。
