Despite a growing body of research outlining the harms of thirdhand smoke (THS), the public remains generally unaware of risks and exposure routes. This project built on past tobacco prevention campaigns and the tenants of McGuire's input-output model to implement and evaluate a seven-month Facebook-disseminated campaign seeking to improve THS awareness among California adults ( = 1087). Multilinear regression showed that THS-related knowledge ([6] = 19.31, < .01), attitude ([6] = 13.88, < .05), and efficacy ([6] = 13.81, < .05) significantly increased by the campaign's end, with messages highlighting children's health ( = .110, < .05), pets ( = .145, < .01), and dust reservoirs ( = .144, < .01) as the most persuasive. Path analysis modeling found campaign recall to be associated with changes in knowledge (= .161, < .01), which predicated attitude change (= .614, < .001) and, in turn, behavior change (= .149, < .05). Findings suggest social media campaigns should continue to educate diverse populations about new tobacco risks and that tobacco control advocates should consider integrating educational THS messages.
尽管越来越多的研究概述了三手烟 (THS) 的危害，但公众普遍仍不知道其风险和暴露途径。本项目以过去的烟草预防运动和 McGuire 的投入-产出模型为基础，实施并评估了一项为期七个月的 Facebook 传播活动，旨在提高加利福尼亚成年人对 THS 的认识（= 1087）。多元线性回归显示，THS 相关知识（[6] = 19.31， < 0.01）、态度（[6] = 13.88， < 0.05）和效能（[6] = 13.81， < 0.05）在活动结束时显著提高，信息强调儿童健康（= 0.110， < 0.05）、宠物（= 0.145， < 0.01）和灰尘储库（= 0.144， < 0.01）最具说服力。路径分析模型发现，活动回忆与知识变化相关（= 0.161， < 0.01），这预示着态度变化（= 0.614， < 0.001），进而预示着行为变化（= 0.149， < 0.05）。研究结果表明，社交媒体活动应继续向不同人群宣传新的烟草风险，而烟草控制倡导者应考虑整合教育性的 THS 信息。
