ABSTRACT

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 (n = 1087). Multilinear regression showed that THS-related knowledge (χ²[6] = 19.31, p < .01), attitude (χ²[6] = 13.88, p < .05), and efficacy (χ²[6] = 13.81, p < .05) significantly increased by the campaign’s end, with messages highlighting children’s health (r = .110, p < .05), pets (r = .145, p < .01), and dust reservoirs (r = .144, p < .01) as the most persuasive. Path analysis modeling found campaign recall to be associated with changes in knowledge (β = .161, p < .01), which predicated attitude change (β = .614, p < .001) and, in turn, behavior change (β = .149, p < .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.

摘要

尽管越来越多的研究概述了三手烟 (THS) 的危害，但公众仍然普遍不了解风险和接触途径。该项目建立在过去的烟草预防活动和 McGuire 投入产出模型的承租人的基础上，以实施和评估为期七个月的 Facebook 传播活动，旨在提高加利福尼亚成年人的 THS 意识 ( n = 1087)。多元线性回归表明，THS 相关知识 ( χ ² [6] = 19.31，p < .01)、态度 ( χ ² [6] = 13.88，p < .05) 和功效 ( χ ² [6] = 13.81，p< .05) 在活动结束时显着增加，信息强调儿童健康 ( r = .110, p < .05)、宠物 ( r = .145, p < .01) 和粉尘库 ( r = .144, p < .01) 最具说服力。路径分析模型发现运动回忆与知识变化相关 ( β  = .161, p < .01)，这预示着态度变化 ( β  = .614, p < .001)，反过来，行为变化 ( β  = .149，页< .05)。调查结果表明，社交媒体活动应继续就新的烟草风险对不同人群进行教育，烟草控制倡导者应考虑整合 THS 教育信息。
