Aw. Reardon et al., THE DEVELOPMENT AND FIELD TESTING OF MATERIALS ON DIABETES FOR PERSONS WITH LOW-VISION OR LOW-LITERACY, Journal of visual impairment & blindness, 87(9), 1993, pp. 347-348
This article describes the development and field testing of topic-spec
ific instructional materials on diabetes with 98 patients at two large
teaching hospitals who had low vision and/or low literacy. A pretest

reduction in wrong answers overall and a 72 percent reduction in wrong
answers by a subset with low vision.
