Test of Functional Health Literacy in Adults (TOFHLA). Parker RM, Baker DW, Williams MV, et al. The test of functional health literacy in adults: a new instrument for measuring patients' literacy skills. J Gen Intern Med 1995; 10:537-41. This article describes the TOFHLA which assesses reading comprehension of health information by asking subjects to read passages in which every 5-7 words are omitted and the subject has to select a correct word from among four word choices. This instrument also involves subject responding to specific questions from a sample of health instructions.
Other tools such as the Fry tool for measuring reading level of materials are found in Doak, Doak & Root, 1996 cited above.
