Efficacy of Radio Entertainment Education in promoting health behavior: A Meta-analysis.

This article focuses on the effectiveness of radio-based entertainment education (EE) programs in promoting health-related knowledge, attitudes, intentions, and behaviors, particularly in developing countries. A meta-analysis of 20 published studies involving over 32,000 participants found that radio EE programs produce small but significant positive effects on health knowledge, attitudes, and behaviors, though not on behavioral intentions. The analysis identified key moderators influencing these effects, including repeated exposure to multiple episodes, type of health issue (notably family planning and HIV), and research design, with survey-based studies showing stronger effects than experimental ones. The findings highlight radio's unique advantages—such as wide reach, low cost, and adaptability to digital formats—as an effective medium for health communication, especially in resource-limited settings, and suggest that repeated, narrative-driven messaging enhances audience engagement and behavioral outcomes.
