Sustained mass media campaigns have been recommended to stem the tobacco epidemic in the United States. Propensity score matching (PSM) was used to estimate the effect of awareness of a national smoking cessation media campaign (EX) on quit attempts and cessation-related cognition. Participants were 4,067 smokers and recent quitters aged 18-49 in targeted U.S. media markets. Controlling for potential confounders through PSM and regression analysis, confirmed awareness of EX was not significantly associated with either outcome at 6-month follow-up. Matched analyses excluding 217 quitters resulted in a significant effect of EX on both outcomes.
持续的大众媒体宣传活动被推荐用于遏制美国的烟草流行。倾向评分匹配（PSM）被用于估计对全国戒烟媒体宣传活动（EX）的认识对戒烟尝试和戒烟相关认知的影响。参与者是年龄在 18-49 岁的目标美国媒体市场中的 4067 名吸烟者和最近的戒烟者。通过 PSM 和回归分析控制潜在混杂因素后，在 6 个月随访时，确认对 EX 的认识与两种结果均无显著关联。排除 217 名戒烟者的匹配分析得出，EX 对两种结果均有显著影响。
