Readability of HIV/AIDS educational materials: the role of the medium of communication, target audience, and producer characteristics.
The reading difficulty of many HIV/AIDS brochures and pamphlets limits their effectiveness. This analysis addresses correlates of readability in 136 HIV/AIDS educational items. Readability is measured using the SMOG Index. The medium of communication is significantly related to readability: comic books and brochures are, on average, more readable than books and pamphlets (10.9 versus 11.9). The target audience also differentiates readability. Materials for HIV antibody test seekers, the general community, and sexually active adults have a more difficult reading grade, averaging 12.1, whereas materials for ethnic minorities average a more readable 9.2. The producer organization's type and location are unrelated to readability, but an AIDS-specific organizational focus correlates with better readability (grade 10.8 vs. 11.8). These findings remain significant in multivariate analysis. The results indicate that brochures and comics are more likely to be comprehended by low-literacy populations, that an understanding of the literacy of target audiences is needed to produce materials with appropriate reading levels, and that policies to influence producer organizations may result in the creation of more readable materials.
