The comprehensibility of Australian educational literature for patients with asthma.

Abstract

Education of patients with asthma is aimed at improving their knowledge, skills and attitudes, and thus compliance and control. Patient information pamphlets play a role in education, medication information and informed consent processes, and must be understood. We assessed the comprehensibility of Australian pamphlets on asthma. 50 Australian pamphlets on asthma (written in English for adults) were selected from the Asthma Foundation, a teaching hospital in South Australia, the pharmaceutical industry, the National Asthma Campaign and specialist books and journal articles. The Australian Rix readability formula was used to estimate the grade of reading difficulty, and thus comprehensibility, of these patient information pamphlets (grade 1 = most comprehensible; grade 12 = most difficult). The mean grade of reading difficulty of the 50 patient information pamphlets was 8 (SD, 1.4; range, 6-11). One-third were written at or above grade 9 and two-thirds were at or above grade 8. As recent educational attainment data suggest that up to 52% of 15-69-year-olds in Australia comprehend text at or below grade 7, a substantial number of pamphlets on asthma are beyond the reading and comprehension abilities of many of their target population.
