Abstract
In this paper, we conducted a meta-analysis of published studies on the effects of entertainment education (EE) on health communication. A search of databases identified 22 studies (N = 19517) that met our inclusion criteria and contained relevant statistics. Analysis of the results suggested that overall, EE's effects on health outcomes – as measured by knowledge, attitudes, intention, and behaviors – was small but significant, with an average effect size (r) of .12, p < .001. Research designs (field studies vs. experiments) and exposure time (multiple episodes vs. one episode) were significant moderators of influence of EE in health communication. However, the impact of delivery channels, health issues, and study locations was not significant.

Notes
1. We reported two separate effect sizes for the study by Bouman et al. (Citation1998) because it examined two different health issues: heart disease prevention and organ donations.
2. Brodies et al. (Citation2001) measured behaviors by asking if the respondents had spoken to the doctor or a health professional about medical problems because of something they saw on ER. For our analysis, we used data from the Wave 1 Survey, conducted on September 1997. Knowledge measures were four items measuring awareness of both control and HPV prevention during the 1997 post-show survey (see p. 195).
