Assessing the potential link between smoking behavior and exposure to mass media depictions of smoking on social networking Web sites.
A representative longitudinal panel of 200 young adults in Connecticut.
Telephone surveys were conducted by using computer assisted telephone interviewing technology and electronic dialing for random digit dialing and listed samples.
Connecticut residents aged 18 to 24 years.
To measure encoded exposure, respondents were asked whether or not they had smoked a cigarette in the past 30 days and about how often they had seen tobacco use on television, in movies, and in social media content. Respondents were also asked about cigarette use in the past 30 days, and a series of additional questions that have been shown to be predictive of tobacco use.
Logistic regression was used to test for our main prediction that reported exposure to social media tobacco depictions at time 1 would influence time 2 smoking behavior.
Encoded exposure to social media tobacco depictions (B = .47, p < .05) was a significant predictor of time 2 smoking, even after controlling for all the aforementioned predictors.
Our results suggest that social media depictions of tobacco use predict future smoking tendency, over and above the influence of TV and movie depictions of smoking. This is the first known study to specifically assess the role of social media in informing tobacco behavior.
评估吸烟行为与社交网站上吸烟的大众媒体描述曝光之间的潜在联系。
对康涅狄格州200名年轻人进行具有代表性的纵向跟踪研究。
采用计算机辅助电话访谈技术和电子拨号进行随机数字拨号及列出样本的方式进行电话调查。
年龄在18至24岁的康涅狄格州居民。
为测量编码曝光，询问受访者在过去30天内是否吸过烟，以及他们在电视、电影和社交媒体内容中看到烟草使用的频率。还询问了受访者过去30天的吸烟情况，以及一系列已被证明可预测烟草使用的其他问题。
采用逻辑回归来检验我们的主要预测，即第1阶段报告的社交媒体烟草描述曝光会影响第2阶段的吸烟行为。
即使在控制了所有上述预测因素之后，编码的社交媒体烟草描述曝光（B = 0.47，p < 0.05）仍是第2阶段吸烟的显著预测因素。
我们的结果表明，除了电视和电影中吸烟描述的影响之外，社交媒体上的烟草使用描述可预测未来的吸烟倾向。这是第一项专门评估社交媒体在影响烟草行为方面作用的已知研究。
