Message content in anti-smoking public service announcements (PSAs) can be delivered explicitly (directly with concrete statements) or implicitly (indirectly via metaphor), and the method of delivery may affect the efficacy of those PSAs. The purpose of this study was to conduct an initial test of this idea using tobacco industry manipulation PSAs in adolescents. A 2 (age: 11-14 years old; 15-17 years old)x2 (message delivery: implicit, explicit) mixed model design was used. There was a significant main effect of message delivery: Tobacco industry manipulation PSAs that delivered their messages explicitly were associated with stronger levels of smoking resistance self-efficacy compared to tobacco industry manipulation PSAs that delivered their messages implicitly. No significant main effects of age were found nor were any interactions between age and message delivery. These results suggest that message delivery factors should be taken into account when designing anti-smoking PSAs.
反吸烟公益广告（PSA）中的信息内容可以通过明确（直接用具体的陈述）或隐晦（通过隐喻间接传达）的方式传递，而传递方式可能会影响这些 PSA 的效果。本研究旨在通过对青少年进行烟草业操纵 PSA 的初步测试来验证这一观点。采用了 2（年龄：11-14 岁；15-17 岁）x2（信息传递：隐晦、明确）混合模型设计。信息传递方式有显著的主效应：与隐晦传递信息的烟草业操纵 PSA 相比，明确传递信息的烟草业操纵 PSA 与更强的吸烟抵制自我效能感相关。年龄没有显著的主效应，年龄和信息传递之间也没有交互作用。这些结果表明，在设计反吸烟 PSA 时应考虑信息传递因素。
