title: Creating a gold standard for the readability measurement of health texts.
abstract: Developing easy-to-read health texts for consumers continues to be a challenge in health communication. Though readability formulae such as Flesch-Kincaid Grade Level have been used in many studies, they were found to be inadequate to estimate the difficulty of some types of health texts. One impediment to the development of new readability assessment techniques is the absence of a gold standard that can be used to validate them. To overcome this deficiency, we have compiled a corpus of 324 health documents consisting of six different types of texts. These documents were manually reviewed and assigned a readability level (1-7 Likert scale) by a panel of five health literacy experts. The expert assigned ratings were found to be highly correlated with a patient representatives readability rating (r = 0.81, p<0.0001).
