关于在线同伴互动对健康行为改变的影响知之甚少。本研究探讨了在戒烟的在线社交网络中暴露于尼古丁替代疗法（NRT）的同伴情绪与NRT使用之间的关系。参与者是3297名参加互联网戒烟计划的吸烟者，参加了一项随机试验，并完成了3个月的随访。一半的人接受了免费的NRT作为试验的一部分。自动文本分类识别了一个或多个参与者在社交网络中接触到的27，038个关于NRT的帖子。对NRT的情绪在亚马逊土耳其机械上进行了评级。参与者对NRT的同伴情绪的暴露是通过分析点击流数据来确定的。改良泊松回归检查了3个月时自我报告的NRT使用情况，作为NRT情绪暴露的函数，控制研究组和暴露后。五分之一的参与者（19.3%，n = 639）暴露于任何NRT相关帖子（平均暴露= 6.5 ± 14.7，平均情绪= 5.4 ± 0.8）。情绪暴露和NRT使用之间的关联因接受免费NRT而异。在未接受免费NRT的受试者中，NRT积极情绪的更多暴露与NRT使用的可能性增加相关（校正率比1.22，95% CI 1.01，1.47; p = .043），而在接受免费NRT的受试者中未观察到这种关系（p = .48）。当吸烟者自己获得NRT时，暴露于对NRT的积极情绪与NRT使用增加相关。突出显示用户生成的包含积极NRT情绪的内容可能会增加寻求治疗的吸烟者使用NRT。
Little is known about the influence of online peer interactions on health behavior change. This study examined the relationship between exposure to peer sentiment about nicotine replacement therapy (NRT) in an online social network for smoking cessation and NRT use. Participants were 3297 current smokers who enrolled in an Internet smoking cessation program, participated in a randomized trial, and completed a 3-month follow-up. Half received free NRT as part of the trial. Automated text classification identified 27,038 posts about NRT that one or more participants were exposed to in the social network. Sentiment towards NRT was rated on Amazon Mechanical Turk. Participants’ exposure to peer sentiment about NRT was determined by analysis of clickstream data. Modified Poisson regression examined self-reported use of NRT at 3-months as a function of exposure to NRT sentiment, controlling for study arm and post exposure. One in five participants (19.3%, n = 639) were exposed to any NRT-related posts (mean exposure = 6.5 ± 14.7, mean sentiment = 5.4 ± 0.8). The association between sentiment exposure and NRT use varied by receipt of free NRT. Greater exposure to positive NRT sentiment was associated with an increased likelihood of NRT use among participants who did not receive free NRT (adjusted rate ratio 1.22, 95% CI 1.01, 1.47; p = .043), whereas no such relationship was observed among participants who did receive free NRT (p = .48). Exposure to positive sentiment about NRT was associated with increased NRT use when smokers obtained it on their own. Highlighting user-generated content containing positive NRT sentiment may increase NRT use among treatment-seeking smokers.
