Summary

This study looks at how smokers with different reading skills respond to various health messages about smoking risks. About 494 smokers will listen to and read messages that are either factual or emotional, and either highlight benefits of quitting or costs of not quitting. The goal is to see which message types increase smokers' intention to quit and improve their attitudes toward quitting.
