Effectiveness of the Radio as a Health Information Source

This study assesses the radio as a source of health information and identifies contributing factors to listeners' intentions to change health-related behavior. After listening to a 1-hour health-talk radio program, 99 participants completed an Internet-based survey instrument. Results indicate 27.3% of participants regularly obtained health information from the radio and 68.7% from the Internet; 92.9% of participants reported an increase in knowledge and 65.7% reported intentions to change health behaviors. Participants were more likely to report behavior change intentions if they obtained health information from multiple sources (OR = 1.47). Implications of this study emphasize making radio content available via the Internet.
