We will assess health literacy with the Short Test of Functional Health Literacy in Adults (STOFHLA). The STOFHLA is a brief version of the widely used instrument, the Test of Functional Health Literacy in Adults (TOFHLA) that measures patients' ability to comprehend situations often encountered in the health care setting; e.g., reading registration forms and instructions for diagnostic tests. It is a 36-item reading comprehension test written in 14-point font that requires 7 minutes to complete.
