Health literacy is critical to effective communication between individuals and their health care providers. However there is little consistency in conceptualization and measure of health literacy. The objective of this review is to examine existing health literacy models and measures to assess their application to limited English proficient population in the context of information and communication technology. Communication platforms change with the development of new technology and existing health literacy models and measures are insufficient to capture the complex interaction that occurred in these communication platforms. A new health literacy model composed of four domains: sources, context, process, and outcome were introduced.
